Description:

TECHNICAL FIELD

The present invention relates in general to a cleaning and storage system for an aspirator instrument. The present invention more particularly relates to a cleaning and storage system for a body cavity aspirator instrument which facilitates the storage of a body cavity aspirator instrument when not in use and which further facilitates the cleaning of the body cavity aspirator instrument prior to its use by a patient as well as sanitary storage of the instrument after its use.

BACKGROUND

For many patient care applications, bodily fluids, such as mucus fluids and meconium fluids, as well as other potentially harmful bodily fluids must be removed from a patient and disposed of in a safe and efficient manner. In this regard, there have been many different types and kinds of aspirator instruments, devices and tools for moving bodily fluids by suction or vacuum processes. For example, reference may be made to the following U.S. Pat. Nos. 5,333,607; 5,183,467; 5,062,835; 5,038,766; 5,002,534;and 4,921,488, each of said patents being incorporated herein by reference.

As disclosed in the foregoing mentioned patents, various aspirator instruments are configured for removing certain types of bodily fluids from specific body cavities. For example, U.S. Pat. No. 5,183,467 discloses an aspirator instrument which is used to dislodge and remove secretions, mucus and debris from a nasal passageway of a user or patient, while U.S. Pat. No. 5,062,835 discloses an aspirator device which can remove meconium or mucus fluids from a stomach or lung cavity during delivery of an infant.

Aspirator instruments then, are configured in various shapes depending upon their intended use and more specifically depending upon the shape of the body cavity holding the bodily fluids to be removed. For example, U.S. Pat. No. 5,002,534 discloses a very common type of oral aspirator device for removing fluids from the mouth and throat cavities of a user or patient.

Because the removal of mucus fluids from the mouth and throat of patients confined in a primary care facility, such as a hospital facility, is such a common requirement in patient care, most, if not all, primary care facilities are equipped with bedside access control consoles. Such access control consoles provide primary care givers immediate access to gases, monitoring equipment and suction/vacuum/water sources for patient care and treatment.

U.S. Pat. No. 5,002,534 describes in detail the typical use of such an oral aspirator instrument indicating the aspirator instrument is attached to the neck of a user/patient using a cord so that a mouthpiece or Yankauer tip instrument can be easily inserted into the mouth of the patient for drawing mucus and other fluids from the body cavity of the patient.

While such an arrangement may have been satisfactory for some applications, it has proven to be less than satisfactory in that a health care provider when not using the aspirator is compelled to either remove the aspirator instrument from the aspirator or lay the instrument with the vacuum tube attached thereon on the patient or the bed of the patient. Thus, if the instrument has been in use, residual body fluids may contaminate the patient or the bed of the patient creating an unwanted and undesired health risk due to the presence of undesirable bacteria and harmful bodily fluids.

Conversely, if the user desires to maintain a safe, clean environment, the aspirator must be utilized promptly so that the Yankauer instrument can be removed and immediately disposed of or alternately removed and placed in a proper container for cleaning and sterilization purposes.

While such a procedure can be followed for minimizing the creation of unwanted and undesired health risks, it is very expensive and time consuming, particularly, where a patient must have his or her mouth and throat cleared on a regular and short term or elapsed time basis.

Another problem associated with prior known aspirator systems when utilized on a regular short elapsed time basis is associated with the accumulation of residual mucus fluids in and on the Yankauer tip when the vacuum or suction is terminated. In this regard, in many aspirator systems, when the body cavity aspirator instrument is removed from the mouth of the patient, the suction operation is substantially diminished permitting any fluids remaining in the body cavity instrument to be trapped within the tip or end of the instrument and tubing connected to the aspirator.

Some of these problems have been considered and addressed by U.S. Pat. No. 5,752,286 (“the '286 patent”), which is incorporated herein by reference in its entirety. The '286 patent describes a cleaning and storage system for a body cavity aspirator instrument. The system includes a holder for receiving an aspirator instrument for temporary storage purposes between periods of non-use. A wiper cap disposed over the mouth of the holder helps wipe the instrument of residual fluids when being inserted and removed from the holder. An inlet near the bottom of the holder permits the admittance of a cleaning agent to periodically clean the instrument.

While such an arrangement has solved many of the problems associated with the use of aspirator instruments in clean-room environments, increased concern about hospital sterilization in conjunction with the rising costs of healthcare and healthcare equipment has necessitated further improvements. The '286 patent requires that the holder be cleaned periodically in order to maintain sanitary conditions for its continued use. That notwithstanding, it has been found that after a certain period of time, depending on the frequency of use, cleaning is insufficient to maintain sanitary conditions and the entire holder must be replaced. Given the costs associated with replacing the entire holder, it would be desirable to find a solution that would obviate the need to replace the holder while maintaining sanitary conditions that are appropriate for hospital and clinical use.

SUMMARY

The present inventor recognized a need for a cleaning and storage system for a body cavity aspirator instrument that is easily sanitized and has means to prolong its useful life. In one embodiment, a cleaning and storage system for a body cavity aspirator instrument includes storage means having a hollow interior for holding between periods of non-use, the body cavity aspirator instrument. The system also includes a disposable insert shaped to be received within the interior of the storage means. Furthermore, the disposable insert can be removably inserted within the hollow interior of said storage means.

In another embodiment, an insert for a body cavity aspirator instrument cleaning and storage system includes a disposable hollow tube having a proximal end and a distal end. The proximal end forms a lip that folds down a distance toward the distal end of the hollow tube. The proximal end of the hollow tube can be at an angle θ relative to the distal end.

DETAILED DESCRIPTION

Referring now to the drawings, and more particularly to FIGS. 1 and 2 thereof, there is illustrated a cleaning and storage system for a body cavity aspirator instrument. The system includes a hollow holder 30 that can be formed of a moldable plastic material. The system further includes a removable and disposable insert 20 that fits within the hollow section of the hollow holder 30. The holder 30 and disposable insert 20 make up the cleaning and storage system for a body cavity aspirator instrument 10, which is also depicted in FIGS. 1 and 2.

The holder 30 has three regions or ends: a proximal region 35; a medial region 40; and a distal region 45. The proximal region 35 forms an opening 37 that receives the disposable insert 20. The medial region 40 forms a transition between the proximal and distal regions. The medial region 40 can form a bend that results in the proximal region 35 being at an angle θ relative to the distal region 45. In other words, a longitudinal axis of the proximal region 35 is at an angle θ relative to the longitudinal axis of the distal region 45. The angle θ can be designed to be substantially complementary to a given type of aspirator instrument, such as the Yankauer tip mouthpiece instrument 10. In one embodiment, the angle θ is between about 0 degrees and about 12 degrees. In another embodiment, the angle θ is between about 12 degrees and about 16 degrees. In another embodiment, the angle θ is between about 13 degrees and about 15 degrees. In another embodiment, the angle θ is about 14 degrees. In another embodiment, the angle θ is greater than 16 degrees.

Referring now to FIGS. 3, 4 and 5, the removable and disposable insert 20, like the holder 30, has three regions or ends: a proximal region 50, a medial region 60, and a distal region 70. The insert 20 forms a hollow tube that is closed at its distal region 70. The proximal region 50 of the insert 20 forms an opening 57 through which the aspirator instrument 10 can be inserted into the insert 20. The medial region 60 forms a transition between the proximal and distal regions. The medial region 60 can form a bend that results in the proximal region 50 being at an angle θ relative to the distal region 70. In other words, a longitudinal axis of the proximal region 50 is at an angle θ relative to the longitudinal axis of the distal region 70. The angle θ can be designed to be substantially complementary to a given type of aspirator instrument, such as the Yankauer tip mouthpiece instrument 10. In one embodiment, the angle θ1 is between about 0 degrees and about 12 degrees. In another embodiment, the angle θ1 is between about 12 degrees and about 16 degrees. In another embodiment, the angle θ1 is between about 13 degrees and about 15 degrees. In another embodiment, the angle θ1 is about 14 degrees. In another embodiment, the angle θ1 is greater than 16 degrees. Furthermore, the angle θ1 can be substantially complementary to the θ formed by the medial region 40 of the holder 30.

The proximal region 50 of the removable and disposable insert 20 has a proximal end that forms a lip 55. The lip 55 folds down a distance toward the medial and distal regions or ends of the insert 20. The lip can have a circumference and shape that is complementary to the proximal region or end 35 of the holder 30. The inset 20 can be supported by the interface between the top edge 38 of the holder 30 and the bottom surface 58 of the lip 55. Accordingly, the insert 20 can be easily removed by pulling or pushing up on the top lip 55 of the insert.

The insert 20 also has one or more accordion pleats 65 defined along a portion of the distal end or region 70 of the insert 20. The insert 20 can have one, two, three, four, five, or more accordion pleats 65 in its distal region 70. The accordion pleats 65 allow the distal region of the insert 20 to bend as needed to accommodate the size and shape of the aspirator instrument 10 being used.

Other embodiments are within the scope of the following claims.
