Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically to an insertion head of a drainage device for fecal incontinence patients. Background Art

[0002] Fecal incontinence refers to the loss of anal sphincter function, resulting in the patient's inability to control defecation independently. This problem is common in groups such as patients after rectal or anal surgery, spinal cord injury patients, and some elderly people. Currently, for the care of fecal incontinence patients, it mainly relies on external care products such as adult diapers. However, this method cannot clean feces in a timely and effective manner, and it is easy to cause problems such as dermatitis due to the long-term stimulation of the perianal skin by feces.

[0003] In response to the above problems, people have developed drainage devices to drain incontinence patients to avoid problems such as dermatitis and odors caused by long-term contact of diapers with the skin. However, the insertion heads of existing drainage devices have the following problems in actual use: 1. The drainage holes are easily blocked by particulate matter in the feces, resulting in poor drainage; in addition, after the drainage holes are blocked, the pressure outside the insertion head increases, causing feces to easily ooze from the anus, polluting the surrounding environment and causing various odors. 2. The fixing effect of the insertion head in the anus is not good and it is easy to prolapse. The above two factors will also affect each other. For example, after the drainage holes are blocked, the pressure in the intestinal tract increases, making the insertion head more likely to prolapse.

[0004] Therefore, a solution that can effectively solve the blockage of the drainage holes and improve the retention effect of the insertion head needs to be studied urgently. Summary of the Invention

[0005] The present invention aims to provide an insertion head of a drainage device for fecal incontinence patients, which effectively solves the problem of drainage hole blockage and improves the retention effect by improving the drainage holes and the retention balloon.

[0006] To solve the above technical problems, the technical solutions provided by the present invention are as follows:

[0007] An insertion head of a drainage device for fecal incontinence patients, including an insertion head body. A drainage channel is provided at the central position of the insertion head body. A drainage part is provided at the front end of the insertion head, and a connection head for connecting a drainage bag is provided at the tail end;

[0008] A drainage hole is provided at the front end of the drainage part. The drainage hole communicates with the drainage channel. An elastic sleeve membrane is provided at the circumferential position of the drainage hole. The elastic sleeve membrane is hermetically connected to the drainage part and forms a cavity;

[0009] A balloon inflation balloon is provided on the side of the insertion head body close to the connection head. A first inflation channel is provided on one side of the drainage channel in the insertion head body. Both ends of the first inflation channel are respectively connected to the cavity and the balloon inflation balloon;

[0010] After squeezing the drum balloon, the cavity is inflated and the elastic membrane is controlled to bulge.

[0011] As an improvement, a retention balloon is provided in the middle section of the insertion head body, and a second inflation channel for inflating the retention balloon is provided in the insertion head body;

[0012] One side of the insertion head body close to the connection head is provided with an inflation joint, and the second inflation channel is connected to the inflation joint.

[0013] As an improvement, a one-way valve is provided inside the inflation joint.

[0015] As an improvement, a second elastic membrane for increasing friction is provided on one side of the drum balloon close to the connection head;

[0016] The second elastic membrane is in a conical tube shape, with the thinner end fixed on the insertion head body and the thicker end fixed on the retention balloon.

[0017] As an improvement, the insertion head body is made of medical-grade silicone material and has a smooth surface.

[0018] As an improvement, a scale mark is provided on the outer surface of the insertion head body to indicate the insertion depth of the insertion head in the human body.

[0019] As an improvement, the material of the elastic membrane is elastic polyurethane, with a thickness of 0.1 - 0.3 mm, and an antibacterial coating is applied on the outer surface of the elastic membrane.

[0020] As an improvement, anti-slip lines for increasing friction are provided on the outer surface of the second elastic membrane.

[0021] As an improvement, the inflation pressure range of the retention balloon is 10 - 20 kPa, and the maximum inflation volume of the retention balloon is 5 - 10 cm 3 .

[0022] The advantages of the present invention are as follows:

[0023] 1. By providing an elastic membrane and a corresponding inflation structure around the drainage hole, the present invention can effectively prevent the drainage hole from being blocked by particulate matter in feces and ensure the smoothness of drainage. The elastic membrane can bulge and contract with the squeezing of the drum balloon, squeeze the particulate matter at the drainage hole, and promote it to enter the drainage channel for discharge, thus solving the problem of drainage hole blockage and maintaining the normal operation of the drainage device.

[0024] 2. In the present invention, a retention balloon and a second elastic membrane are provided in the middle section of the insertion head body, which can enhance the fixation effect of the insertion head in the anus, prevent it from prolapsing, and the second elastic membrane can also improve the sealing performance with the anal tissue and avoid the leakage of drainage.

Detailed implementation manners

[0036] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Components of the embodiments of the present invention usually described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0037] Embodiment 1

[0038] This embodiment discloses a placement head of a drainage device for fecal incontinence patients, including a placement head body 1. A drainage channel 2 is provided at the central position of the placement head body 1. A drainage part 3 is provided at the front end of the placement head body 1, and a connection head 4 for connecting a drainage bag is provided at the tail end.

[0039] A drainage hole 5 is provided at the front end of the drainage part 3. The drainage hole 5 is communicated with the drainage channel 2. An elastic sleeve film 6 is provided at the circumferential position of the drainage hole 5. The elastic sleeve film 6 is hermetically connected to the drainage part 3 and forms a cavity 7. A balloon 8 is provided on one side of the placement head body 1 close to the connection head 4. A first bulging channel 9 is provided on one side of the drainage channel 2 inside the placement head body 1. Both ends of the first bulging channel 9 are respectively connected to the cavity 7 and the balloon 8. After squeezing the balloon 8, the cavity 7 is inflated and the elastic sleeve film 6 is controlled to bulge.

[0040] The main function of the elastic sleeve film 6 is to adjust the size of the drainage hole 5. When there are particulate matters in the drainage and the drainage hole 5 is blocked, it is easy to cause the pressure near the patient's anus to rise rapidly and seep out from the anus bypassing the placement head. The elastic sleeve film 6 can effectively avoid the above problems. When medical staff find that the drainage speed decreases during the drainage process, they can suspect that the drainage hole 5 is blocked. At this time, repeatedly squeeze the balloon 8, and the elastic sleeve film 6 can bulge and contract following the balloon 8, squeezing the particulate matters at the drainage hole, so as to promote the particulate matters to enter the drainage channel 2 and be drained out.

[0041] The number of the drainage holes 5 is two, and they are arranged in a staggered manner on both sides of the placement head body 1.

[0042] In the middle section of the placement head body 1, there is an indwelling balloon 10. Inside the placement head body 1, there is a second air injection channel 11 for inflating the indwelling balloon 10. On the side of the placement head body 1 close to the connection head 4, there is an air injection joint 12. The second air injection channel 11 is connected to the air injection joint 12. Inside the air injection joint 12, there is a one-way valve 13. There is also a sealing cover 14 on the air injection joint 12. The sealing cover 14 is screwed to the air injection joint 12, and there is a sealing gasket 15 inside the sealing cover 14. On the side of the air injection balloon 8 close to the connection head 4, there is a second elastic membrane 16 for increasing friction. The second elastic membrane 16 is in the shape of a conical cylinder, with the thinner end fixed on the placement head body 1 and the thicker end fixed on the indwelling balloon 10. After injecting air through the air injection joint 12, the one-way valve 13 can initially seal the air injection channel 12 to prevent gas leakage from the air injection channel 12. Then, the sealing cover 14 is screwed onto the air injection joint 12 to ensure the sealing of the air injection joint 12.

[0043] The indwelling balloon 10 can increase the diameter of the corresponding position to be used for retaining the placement head body 1 at the anal position. At the same time, during the drainage process, the indwelling balloon 10 can block the anus to prevent the drainage from leaking from the anus. The second elastic membrane 16 can further improve the combination effect with the anus. When the second elastic membrane 16 is close to the anus, the second elastic membrane 16 can form folds on the outer side close to the outer side of the indwelling balloon 10 under the extrusion of the sphincter, further increasing the friction between the indwelling balloon 10 and the tissue at the anus to prevent the indwelling balloon 10 from slipping out of the anus. In addition, the folds can also improve the sealing between the indwelling balloon 10 and the anal tissue to prevent the drainage from seeping out between the indwelling balloon 10 and the anal tissue. The outer surface of the second elastic membrane 16 is provided with anti-slip lines for increasing friction.

[0044] The placement head body 1 is made of medical-grade silicone material and has a smooth surface, which can effectively reduce the irritation of the placement head body 1 to the intestine for easier placement. The outer surface of the placement head body 1 is provided with scale markings 17 for indicating the insertion depth of the placement head into the human body. The material of the elastic sleeve membrane 6 is elastic polyurethane with a thickness of 0.1 - 0.3 mm, and the outer surface of the elastic sleeve membrane 6 is coated with an antibacterial coating. The inflation pressure range of the indwelling balloon 10 is 10 - 20 kPa, and the maximum inflation volume of the indwelling balloon 10 is 5 - 10 cm 3 。

[0045] The usage method of this solution is as follows:

[0046] 1. Check whether all components of the drainage device placement head are complete and prepare medical lubricant to reduce friction during the placement process.

[0047] 2. The patient assumes a suitable position (such as the lateral position or the knee-chest position), and cleans the skin around the anus. Apply an appropriate amount of medical lubricant to the front end of the insertion head body 1, gently insert it into the anus, and control the insertion depth according to the scale mark 17 to ensure that the indwelling balloon 10 is in a suitable position within the anus. After insertion in place, inject an appropriate amount of gas into the indwelling balloon 10 through the inflation connector 12 (the inflation pressure is controlled at 10 - 20 kPa, and the maximum inflation volume does not exceed 10 cm 3 ), causing the indwelling balloon 10 to expand and fixing the insertion head body 1 within the anus to prevent it from slipping out.

[0048] 3. Connect the drainage bag to the connector 4 to ensure a firm connection. When performing drainage, observe the drainage situation. If it is found that the drainage speed decreases, it may be that the drainage hole 5 is blocked. At this time, repeatedly squeeze the inflation balloon 8 to cause the elastic membrane 6 to bulge and contract, squeezing the particulate matter at the drainage hole 5 to promote its entry into the drainage channel 2 for discharge.

[0049] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
