Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a disposable medical feces collecting device. Background Art

[0002] For some patients who are bedridden for a long time and cannot take care of themselves, the overflow of feces will cause serious pollution and bring great difficulties to nursing work. Long-term or repeated exposure of the patient's skin to feces can easily cause inflammation such as redness, swelling, pain, eczema, etc., causing incontinence-related dermatitis. In order to prevent feces from contacting the skin during the treatment process, the feces of patients with incontinence and diarrhea need to be collected and processed.

[0003] The feces collector is mainly suitable for patients who have diarrhea or fecal incontinence and are in critical condition and need to defecate in bed, so as to avoid contaminating clothes and beds, reduce skin damage or wound contamination of patients, not only increase patient comfort, but also reduce the daily workload of medical staff. The feces collector is also suitable for patients with long surgery time to maintain the cleanliness of the operating table and reduce the contamination of surgical wounds by patients' excrement. The existing feces collector only plays a major role in feces collection, but does not protect the skin around the anus and the sacrum, especially the special perineum of female patients. In addition, it does not take into account the comfort of patients when using the feces collector.

[0004] Some patents on feces collectors are disclosed in the prior art, among which the utility model patent with the announcement number CN213284703U discloses a feces collection device, which includes a negative pressure bucket, a bucket cover, a first conduit, a second conduit, a connecting pipe, an ostomy bag, a negative pressure conduit and a negative pressure aspirator; the negative pressure bucket is provided with a bucket cover, the bucket cover is provided with a first conduit and a second conduit, one end of the connecting pipe is connected to the liquid outlet of the ostomy bag, and the other end is connected to the first conduit, one end of the negative pressure conduit is provided on the second conduit, and the other end is connected to the negative pressure aspirator. Although the problem that the excessive dumping of feces will cause irritation to the skin, which will easily cause the ostomy bag to fall off and increase the workload of the nurses is solved, the problem of patient comfort in use is not considered.

[0005] In view of this, the inventor conducted in-depth research on the demand for a feces collector with a simple structure, easy operation and comfortable use for patients, and thus the present case was produced. Utility Model Content

[0017] Furthermore, an anti-blocking valve is provided on the side wall of the hose.

[0018] Furthermore, the waterproof layer is polyvinyl chloride, the pressure relief layer is polyurethane foam, and the skin-friendly layer is medical-grade silicone.

[0019] Beneficial effects:

[0020] The beneficial effects produced by adopting the technical solution of the utility model are as follows:

[0021] (1) The chassis composed of a skin-friendly layer, a pressure-reducing layer and a waterproof layer can provide good pressure-reducing protection for the skin of the sacrum and coccyx for clinically critically ill patients or patients who are bedridden for a long time and cannot turn over and move due to illness. It can prevent pressure damage to the skin of the sacrum and coccyx of patients, and at the same time, it is helpful to prevent feces from accumulating on the patient's buttocks and causing side leakage, greatly improving the effect of feces collection. The negative pressure suction function is designed to better collect feces when the patient has a lot of feces or exhausts a lot, which is prone to leakage, thereby reducing the work pressure of nursing staff. In addition, the collection chassis is set to a special-shaped structure corresponding to the different human body structures of men and women, especially for the special perineum of female patients.

At the same time, it also makes female patients more comfortable when using the device, while also protecting the patient's perianal skin and sacral coccyx skin.

[0023] (3) The stool collection part is set as an arc-shaped hollow collection ball. The shape of the arc-shaped hollow collection ball is designed because the sphere is a round structure. When in use, the collection ball is placed between the patient's legs, which will bring greater comfort to the patient. At the same time, the spherical structure will not cause pressure damage. If a rectangular or cube is used, the existing angular edges are likely to cause iatrogenic damage to the patient. Therefore, the design of the arc-shaped hollow collection ball brings a comfortable use experience to the patient.

[0024] (4) An anti-backflow connector is provided at the end of the negative pressure suction connector, which effectively prevents sputum from flowing back through a one-way flow structure, making it more hygienic and safer. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] During the specific implementation, the collecting chassis 1 is placed on the patient's buttocks so that the patient's anus corresponds to the collecting hole. When the negative pressure suction device 10 is started and the patient defecates, the feces enters the hose 8 through the collecting hole, and the feces in the hose 8 enters the collecting sphere 7 for temporary storage of feces and is temporarily stored. When it is temporarily necessary to retain a feces sample, the feces sample can be retained from the connecting part 11. When the amount of feces is large, a biodegradable agent or sodium hydroxide solution can be injected from the injection hole 12 to dissolve the feces in the collecting sphere 7. When cleaning the feces, air is allowed to enter the negative pressure suction barrel through the air release valve 14 to stop the suction tube 9 from draining the feces, and then the suction tube 9 is pulled out from the negative pressure suction barrel. In addition, the negative pressure suction barrel can use a conventional negative pressure suction barrel with a disposable inner bag in the outer barrel. After use, the inner bag is discarded to disinfect the outer barrel, or a disposable negative pressure barrel can be used for replacement.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
