Description

Technical Field

[0001] This utility model relates to the field of fecal collection technology, specifically a water sample fecal collection device with flushing and negative pressure suction functions. Background Technology

[0002] In the field of medical care, the care of patients with severe diarrhea has always been a challenging problem. These patients often pass large amounts of watery stools due to intestinal dysfunction and other reasons, and fecal incontinence is relatively common.

[0003] Currently, there is no ideal solution for stool collection in patients with severe diarrhea. Traditional care methods, such as simply using diapers or nursing pads, are insufficient to effectively prevent the seepage and spread of watery stools, leading to continuous contact between harmful substances in the feces (such as bacteria and digestive enzymes) and the perianal skin. These substances can damage the skin's barrier function, causing an imbalance in the skin's pH level, which in turn irritates the skin and easily triggers incontinence dermatitis.

[0004] Incontinence-associated dermatitis not only causes discomfort such as pain and itching, reducing patients' quality of life, but also increases the risk of skin infections, prolongs hospital stays, and exacerbates the financial burden on patients and their families. Furthermore, the frequent handling of patient feces and contaminated nursing supplies significantly increases the workload of medical and nursing staff, reducing the efficiency of nursing care.

[0005] Existing stool collection devices suffer from problems such as poor fit, low collection efficiency, and lack of effective cleaning and drainage functions, failing to meet actual clinical needs. Therefore, there is an urgent need to develop a stool collection device that can efficiently collect watery stools from patients with severe diarrhea, while also possessing cleaning and drainage functions, effectively reducing fecal irritation to the skin and preventing incontinence dermatitis.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0026] Example 1

[0027] To facilitate the collection and removal of watery stool, and to simplify the cleaning of the collection device, this embodiment provides a watery stool collection device. This device adheres to the patient's perianal area and can be connected to a negative pressure device. Therefore, when the patient defecates watery stool, the negative pressure device can be activated to pump the stool out, preventing prolonged contact between the stool and the perianal skin and potential skin irritation leading to incontinence dermatitis. Furthermore, the collection device can also be connected to a flushing device to clean the device after the watery stool has been discharged, thus achieving perianal cleanliness for the patient.

[0028] The aforementioned negative pressure devices can be configured as medical negative pressure pumps, central suction systems, or negative pressure aspirators. Negative pressure aspirators generally consist of a pressure regulator, a collection bottle, and tubing. A negative pressure environment is created by a pump (mechanical or electric). When the negative pressure terminal is connected, a negative air pressure is generated inside the collection bottle, using the pressure difference to guide water samples, etc., into the collection bottle through the tubing. A central suction system generally consists of a vacuum pump, a vacuum tank, a piping system, and a control system. The vacuum pump generates negative pressure, making the pressure inside the vacuum tank lower than the external atmospheric pressure, creating suction. This suction is connected to terminals in various departments through piping. Medical negative pressure pumps create a pressure difference to form a negative pressure area by mechanically or electrically changing the internal volume or gas flow rate. They can be used independently or as components of other negative pressure devices.

[0029] The aforementioned flushing device can be configured as a flushing machine, syringe, etc., capable of receiving dedicated flushing solution, clean water, and saline solution to clean the perianal area, remove embedded debris, and reduce the number of bacteria and viruses. The flushing device can even be configured as an infusion bottle or tubing to deliver the cleaning solution from the infusion bottle to the perianal area.

[0030] like Figure 1 , Figure 2 As shown, to collect watery stool, the collection device includes an ostomy bag 1, an ostomy disc 2, a suction tube 3, and a cleaning tube 4. The ostomy disc 2, suction tube 3, and cleaning tube 4 are respectively located at both ends of the ostomy bag 1. The ostomy disc 2 is made of skin-friendly materials such as hydrocolloids and hydrogels. The ostomy disc 2 adheres to the perianal area, creating a passage between the ostomy bag 1 and the patient's anus. This allows the ostomy bag 1 to temporarily store watery stool when the patient defecates, preventing splashing. Furthermore, the ostomy disc 2 can be cut to fit different adhesion areas. The suction tube 3 is connected to a negative pressure device; therefore, when the negative pressure device is working, the stool can be discharged along the suction tube 3. The cleaning tube 4 is connected to a flushing device, allowing cleaning fluid to be injected into the ostomy bag 1 under the action of the flushing device. The cleaning fluid then flows out along the suction tube 3, achieving cleaning of the ostomy bag 1 and the perianal area.

[0031] Example 2

[0032] like Figure 3 , Figure 4 , Figure 5 As shown, based on Example 1, in order to reduce the treatment cost for patients, the stoma disc 2, suction tube 3, cleaning tube 4 and stoma bag 1 can be set as a detachable structure so that they can be replaced when a certain part is damaged.

[0033] Specifically, an annular end 21 is provided in the middle of the stoma disc 2. The annular end 21 is sleeved at the feed inlet 11, and the clamp 23 sleeved on the outside of the annular end 21 presses the annular end 21 to fit the feed inlet 11. Therefore, under the action of the clamp 23, the annular end 21 can be tightly sleeved at the feed inlet 11, realizing a stable connection between the stoma disc 2 and the stoma bag 1, and also providing convenience for disassembling the stoma bag 1 and the stoma disc 2 as needed.

[0034] In order to effectively achieve the sealed connection between the ostomy bag 1 and the stoma disc 2, annular protrusions 22 and annular grooves 12 are respectively provided on the contact surfaces of the annular end 21 and the inlet 11. Under the action of extrusion pressure, the annular protrusions 22 are filled in the annular grooves 12, which can not only achieve the sealed connection between the ostomy bag 1 and the stoma disc 2, but also increase the resistance to the relative movement of the ostomy bag 1 and the stoma disc 2.

[0035] In order to detachably install the suction tube 3 on the side of the ostomy bag 1, a connecting cap 32 is provided at the end of the suction tube 3. An annular connecting groove 33 is provided on the side wall of the connecting cap 32, and the discharge port 13 of the ostomy bag 1 and the side wall of the annular connecting groove 33 are respectively provided with matching threaded structures. Therefore, the connecting cap 32 can be threaded onto the discharge port 13 to achieve a stable connection between the suction tube 3 and the ostomy bag 1, and to facilitate the disassembly of the suction tube 3 as needed.

[0036] The cleaning tube 4 can be directly connected to the cover 32, or the end of the cleaning tube 4 can be connected to the suction tube 3.

[0037] In addition, a first valve body 31 and a second valve body 41 are respectively provided at the ends of the suction tube 3 and the cleaning tube 4 away from the ostomy bag 1. The unobstructed flow of the suction tube 3 and the cleaning tube 4 can be controlled by the valve bodies, thereby controlling the discharge of excrement.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
