Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Please refer to Figure 1 An embodiment of the utility model provides a negative pressure stool collection device, including a negative pressure drainage device 1 and a drainage pipe 2. The various components of this embodiment are described in detail below in conjunction with the accompanying drawings.
[0021] like Figure 1 As shown, the top of the negative pressure drainage device 1 can be fixedly connected to one end of the drainage tube 2. The drainage tube 2 includes a drainage tube 21, an airbag assembly 22 and a flushing assembly 23. The airbag assembly 22 is fixedly arranged on the outer wall of the front end of the drainage tube 21, and the flushing assembly 23 is fixedly arranged on the outer wall of the front end of the drainage tube 21 and is connected to the inside of the drainage tube 21.
[0022] Specifically, the drainage tube 21 can be integrally formed with the airbag assembly 22 and the flushing assembly 23 .
[0023] Preferably, the interior of the negative pressure drainage device 1 is hollow, the tail end of the drainage tube 21 extends from the top of the negative pressure drainage device 1 and is connected to the hollow cavity of the negative pressure drainage device 1, and a one-way valve 11 is provided inside the pipeline of the drainage tube 21, wherein a one-way valve 11 is provided at the inlet position inside the negative pressure drainage device 1, and the drainage material inside can only enter but not exit.
[0024] In this embodiment, the negative pressure drainage device 1 can be made of transparent soft plastic, and the negative pressure drainage device 1 can be set as a negative pressure drainage bottle or a negative pressure drainage bag, wherein the negative pressure drainage bottle or the negative pressure drainage bag can be manually flattened to form a negative pressure inside the two. The negative pressure force makes the drainage tube 21 negative pressure, which can directly suck out the patient's feces.
[0025] Furthermore, a discharge switch 12 is provided at the bottom outlet position outside the negative pressure drainage device 1, and scale lines 13 can be evenly arranged on the outer wall of the negative pressure drainage device 1. When implemented, the discharge switch 12 can directly realize manual opening and closing operations. After turning on the switch, the negative pressure drainage device 1 can automatically inflate, and the interior is in a positive pressure state. The amount of stool can be seen through the transparent bottle body. In addition, the stool can be directly squeezed out through its bottom outlet, which is convenient for retaining specimens.
[0026] like Figure 2 As shown, the drainage tube 21 can be made of a transparent elastic silicone rubber material, and a collecting head 211 with an umbrella-shaped structure is provided at the head end of the drainage tube 21. The collecting head 211 is configured as a semi-closed and semi-open structure, and a collecting hole 201 is provided in the middle of the top of the collecting head 211. A plurality of arc-shaped openings 202 distributed at intervals in a petal shape are provided on the outer wall of the collecting head 211, and each arc-shaped opening 202 extends downward with the collecting hole 201 as the center and is symmetrically distributed.
[0027] During specific implementation, the silicone head end of the drainage tube 21 is inserted into the patient's anus, and its front end is easily sucked onto the intestinal wall. The semi-closed and semi-open structure of the collecting head 211 can more easily protect the intestinal mucosa and is conducive to collecting stool in the intestine.
[0028] Furthermore, a plurality of drainage holes 212 are evenly recessed on the outer wall of the drainage tube 21 close to the collecting head 211, and the inner wall shape of the drainage holes 212 can be set to a concave semi-arc structure. The drainage holes 212 of the drainage tube 21 are all semi-arc openings, which can prevent the drainage tube 21 from being close to the intestinal wall, so as to better attract the patient's stool.
[0029] like Figure 3 As shown, the airbag assembly 22 may include an perianal airbag 221, an inflatable balloon 222 and an air injection tube 223. The perianal airbag 221 is molded and arranged on the outer wall surface of the drainage tube 21 near the drainage hole 212. One end of the air injection tube 223 is connected to the inner cavity of the perianal airbag 221, and the other end of the air injection tube 223 is connected to the inner cavity of the inflatable balloon 222. A positive pressure valve 224 is arranged at the inner end of the inflatable balloon 222.
[0030] Among them, after the drainage tube 21 is inserted into the patient's anus, the inflatable balloon 222 is pressed and the perianal airbag 221 is inflated and filled through the air injection tube 223. After the perianal airbag 221 expands, the skin on both sides of the patient's gluteal groove can be stretched open, thereby avoiding the skin on both sides of the gluteal groove from being tightly adhered and aggravating the inflammation and ulceration of the skin. The perianal airbag 221 can also be used to fix the drainage tube 21 to prevent it from falling out and prevent the patient's stool from leaking out. In addition, a positive pressure valve 224 is provided at the inner end of the inflatable balloon 222, and the gas can only enter but not exit, so as to prevent the gas from flowing back.
[0031] Specifically, the flushing assembly 23 may include a flushing tube 231 and a flushing connector 232, one end of the flushing tube 231 is connected to one end of the flushing connector 232, and the other end of the flushing tube 231 extends from the side wall of the drainage tube 21 into the interior of the pipeline and extends to the head end of the drainage tube 21.
[0032] The flushing tube 231 can be connected to the head end of the drainage tube 21 with clean saline to prevent the drainage tube 21 from being blocked by feces, or connected to medicine to achieve drug injection, enema and other operations.
[0033] During the specific implementation, first ensure that the discharge switch 12 of the negative pressure drainage device 1 is in the closed state, insert the drainage tube 21 into the anorectal through the patient's anus, and the medical staff repeatedly squeezes and holds the inflatable balloon 221 to inflate the perianal airbag 221 so that it expands in the anorectal and fully fits the inner wall of the anorectal, and then squeezes and flattens the negative pressure drainage device 1 to put it in a negative pressure state. The patient's feces and excrement can flow into the negative pressure drainage device 1 through the collecting head 211 and the drainage hole 212 of the drainage tube 21. The negative pressure drainage device 1 collects the feces and fecal fluid excreted by the patient. The flushing tube 231 can be connected to a syringe or other tools through the flushing connector 232 to inject clean saline or medicine into the head end of the drainage tube 21. The medical staff can clean the patient's anorectal or inject medicine according to the situation.
[0034] To sum up, the utility model can complete the drainage and collection operation of stool by inserting the drainage tube into the patient's anus and rectum, so that the negative pressure drainage device is in a negative pressure state. The umbrella-shaped collecting head of the drainage tube can protect the intestinal mucosa, and the drainage hole can prevent the tube from sticking to the wall and sucking out stool. After the airbag component is inflated and filled, it can prevent the patient's stool from leaking sideways and fix the drainage tube. The flushing component can complete operations such as anti-blocking, cleaning and injection of medicine. The utility model reduces the occurrence of incontinence dermatitis in patients, which not only alleviates the patient's pain and improves the comfort of use, but also reduces the nursing workload of medical staff.
