Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intelligent anus with an artificial intestine and a preparation method thereof. Background Art

[0002] A colostomy is a surgical procedure to remove all or part of the colon, which is a long, tube-shaped organ at the end of the digestive tract. A colon resection may be necessary to treat or prevent certain conditions that affect the colon. A colostomy is then used to create an opening (ostomy) in the abdomen to allow waste to pass out of the body after a section of the large intestine has been removed or bypassed. Waste is removed through the ostomy instead of the anus.

[0003] Since this method has no sphincter to control waste discharge, patients cannot defecate independently and can only collect waste into the drainable ostomy bag system. This not only leads to extremely poor quality of life for patients, but also the severe odor emitted by the ostomy bag cannot be eliminated, which has a serious negative impact on the patient's work, life and interpersonal relationships.

[0004] In order to solve the above problems, the present application proposes an intelligent anus with an artificial intestine and a preparation method thereof. Summary of the invention

[0007] A pressure transmission unit is connected between the artificial intestine body and the artificial anus body, and the pressure transmission unit is used to control the passage of excrement in the artificial intestine body;

[0008] The artificial intestine body and the artificial anus body are both equipped with pressure sensing units, and the pressure sensing units are used to monitor the pressure in the artificial intestine body and the artificial anus body, and discharge of excrement in the artificial intestine body is achieved through the pressure transmission unit.

[0009] As a further optimization solution of the present invention, the pressure transmission unit includes a valve body, which is connected between the artificial intestine body and the artificial anus body and is used to control the passage of excrement in the artificial intestine body.

[0010] As a further optimization scheme of the present invention, the pressure sensing unit is a pressure sensor, the inner walls of the artificial intestine body and the artificial anus body are coated with pressure sensors, and the pressure sensors are used to monitor the pressure inside the artificial intestine body and the artificial anus body.

[0011] As a further optimization scheme of the present invention, the inner wall of the artificial intestine body is also coated with a controller, and the controller is respectively communicated with the pressure transmission unit and the pressure sensing unit. A Bluetooth module is installed on the controller, and the Bluetooth module is used to communicate with a smart phone and a watch.

[0012] As a further optimization solution of the present invention, the artificial intestine body comprises a polymer elastomer;

[0013] The polymer elastomer is one or more of polyurethane elastomer, polystyrene elastomer, silica gel or rubber.

[0014] As a further optimization solution of the present invention, the artificial intestine body is an elastic body with an inner lining spring tube or a braided tube;

[0015] The spring tube or braided tube includes but is not limited to medical stainless steel and nickel-titanium alloy.

[0016] As a further optimization solution of the present invention, the hardness of the artificial intestine body is 40A-90A.

[0017] As a further optimization solution of the present invention, the artificial anus body includes a polyurethane elastomer and a memory metal skeleton.

[0021] Step three, assembly: connect the artificial intestine body to the artificial anus body, and connect a pressure transmission unit between the artificial intestine body and the artificial anus body.

[0022] The above technical solution of the present invention has the following beneficial technical effects:

[0023] 1. Through surgical operation, the artificial intestine body is sutured with the patient's existing intestine, and the artificial anus body is sutured with the existing anus. The pressure in the artificial intestine body and the artificial anus body can be monitored by the pressure sensing unit. When the excrement in the artificial intestine body reaches a certain level and exceeds the preset valve body of the pressure sensing unit, the controller transmits the pressure data of the pressure sensing unit to the patient's mobile phone through the Bluetooth module.

[0032] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0033] like Figure 1-6 As shown, the present invention provides a smart anus with an artificial intestine, comprising an artificial intestine body 1 and an artificial anus body 2 connected to the artificial intestine body 1;

[0034] A pressure transmission unit 3 is connected between the artificial intestine body 1 and the artificial anus body 2, and the pressure transmission unit 3 is used to control the passage of excreta in the artificial intestine body 1. The pressure transmission unit 3 includes a valve body, which is connected between the artificial intestine body 1 and the artificial anus body 2 and is used to control the passage of excreta in the artificial intestine body 1.

[0035] The artificial anus body 2 includes a polyurethane elastomer 21 and a memory metal skeleton 22 . The polyurethane elastomer 21 is coated with the memory metal skeleton 22 , and the memory metal skeleton 22 is used to support the polyurethane elastomer 21 .

[0036] The artificial intestine body 1 and the artificial anus body 2 are both installed with a pressure sensing unit 4, and the pressure sensing unit 4 is used to monitor the pressure in the artificial intestine body 1 and the artificial anus body 2, and the discharge of excrement in the artificial intestine body 1 is achieved through the pressure transmission unit 3. The pressure sensing unit 4 is a pressure sensor, and the inner walls of the artificial intestine body 1 and the artificial anus body 2 are both coated with a pressure sensor, and the pressure sensor is used to monitor the pressure in the artificial intestine body 1 and the artificial anus body 2;

[0037] The inner wall of the artificial intestine body 1 is also coated with a controller 5, which is respectively connected to the pressure transmission unit 3 and the pressure sensing unit 4 for communication. A Bluetooth module is installed on the controller 5, and the Bluetooth module is used to communicate with a smart phone or a watch.

[0038] In a specific embodiment, the artificial intestine body 1 includes a polymer elastomer, and the polymer elastomer is one or more of polyurethane elastomer, polystyrene elastomer, silicone or rubber.

[0039] In a specific embodiment, the artificial intestine body 1 is an elastic body with an inner lining of a spring tube or a braided tube, and the spring tube or the braided tube includes but is not limited to medical stainless steel and nickel-titanium alloy.

[0040] In a specific embodiment, the hardness of the artificial intestine body 1 is 40A-90A, preferably 50A-80A.

[0041] It should be noted that: the artificial intestine body 1 is sutured to the patient's existing intestine through surgical operation, and the artificial anus body 2 is sutured to the existing anus. The pressure in the artificial intestine body 1 and the artificial anus body 2 can be monitored by a pressure sensor. When the excrement in the artificial intestine body 1 reaches a certain level and exceeds the preset valve body of the valve body, the controller 5 transmits the pressure data of the pressure sensing unit 4 to the patient's mobile phone through the Bluetooth module. Then the patient can send an instruction to the controller 5 through the mobile phone. After receiving the instruction, the controller 5 sends an opening instruction to the valve body, so that the pressure transmission unit 3 is in an open state, and the excrement in the artificial intestine body 1 enters the artificial anus body 2 along the pressure transmission unit 3. When the excrement in the artificial intestine body 1 falls on the polyurethane elastomer 21, the excrement gradually accumulates, and when pressure is generated on the polyurethane elastomer 21 and the memory metal skeleton 22, the polyurethane elastomer 21 and the memory metal skeleton 22 will emit The artificial anus body 2 is deformed, thereby opening the excretion port at the bottom of the artificial anus body 2, and excrement is discharged from the excretion port. When the pressure in the intestine is released, the polyurethane elastomer 21 and the memory metal skeleton 22 return to their original state under the action of their own elasticity. After the pressure on the pressure sensing unit 4 is lower than that on the valve body, the signal can be transmitted to the mobile phone through the Bluetooth module. The patient can send a closing command to the controller 5 through the mobile phone, and the controller 5 immediately sends a command to the pressure transmission unit 3, so that the pressure transmission unit 3 is closed. With the continuous changes in the pressure in the intestine, the synergistic effect of the polyurethane elastomer 21 and the memory metal skeleton 22 simulates the peristaltic process of the human intestine, making the entire excretion process more natural and controllable. Through the intelligent pressure monitoring function, the structure allows the patient to autonomously control the excretion according to the prompt, which is convenient and humane, and can effectively eliminate the serious odor caused by the abdominal stoma, improve the patient's living environment, and reduce the adverse effects of the odor on the patient's psychology and social life.
