Description

Technical Field

[0001] The invention belongs to the field of medical and sanitary appliances, and in particular relates to a rectal medication tube sealing component, a stool collecting bag, an enema auxiliary appliance, and a method for collecting excrement after enema. Background Art

[0002] Enemas are widely used in hospitals for two main purposes: first, preoperative bowel cleansing to prevent contamination of the operating table by stool during surgery after anesthesia; and second, enemas are used to assist in the defecation of hospitalized patients who have difficulty defecating on their own. The enema is administered through the anus to the rectum, and the patient then defecates in the bathroom.

[0003] A large proportion of patients who undergo enema are unable to go to the bathroom on their own due to loss of mobility and need to defecate in bed. Currently, the commonly used clinical method is to defecate directly on a nursing pad, but this method has the following disadvantages:

[0004] 1. It often leads to large-scale excrement pollution, emits a pungent odor, increases the difficulty of cleaning and causes discomfort to patients.

[0005] 2. Some patients will have excrement flowing out when taking enema medication, which will affect the enema operation.

[0006] Another method is to use a fecal drainage device, which needs to be inserted into the patient's rectum and left in place for a long time. However, this device can only drain a small amount of watery or loose stools, is prone to clogging, requires professional operation, is expensive, and has significant limitations.

[0007] Therefore, how to collect enema excrement simply, cleanly and hygienically has become a major problem that needs to be solved urgently in clinical enema. Summary of the Invention

[0008] Technical problem: The technical problem to be solved by the present invention is to effectively seal and isolate the delivery section and the administration section of the rectal administration tube when delivering medicine, and to collect excrement on the basis of such isolation to reduce the difficulty of subsequent processing.

[0009] Technical Solution: To address the above technical issues, the present invention utilizes a temporary wearable device. Before the enema, a specially designed, disposable feces collection bag is secured to the patient's anus using a silicone ring, reversed, and then excreted into the bag. A plastic medication nozzle is attached to the bag, through which medical personnel insert a rectal medication tube into the patient's anus to administer the enema. After the enema is completed and the medication tube is removed, the patient begins to excrete feces into the bag. Once defecation is complete, the bag is removed and discarded.

[0010] The specific technical solutions are as follows:

[0011] A rectal administration tube sealing assembly includes a through hole for the rectal administration tube to pass through the administration nozzle, and a sealing ring layer is provided on the inner wall of the through hole;

[0012] The sealing ring layer is made of an elastic material, and the sealing ring layer and the administration tube are sleeved in an interference fit manner.

[0013] The sealing ring layer made of the elastic material can enhance the wrapping property of the rectal administration tube, thereby improving the sealing and isolation effect; through the sealing assembly, the delivery section and the administration section of the rectal administration tube are isolated, providing a basic condition for the collection of excreta.

[0014] Further, the sealing assembly includes a first fastener and a second fastener that are buckled together. An inner concave portion is provided on the first fastener, and a protruding portion is provided on the second fastener;

[0015] A first through hole and a second through hole are respectively provided at the centers of the inner concave portion and the protruding portion. Through the connection method of the fastening member, it is convenient to set the seal on the feces collection bag.

[0016] Further, at least one section of the inner side wall of the inner concave portion is provided with a clamping groove and / or a clamping seat, and a clamping seat / clamping groove matching the clamping groove / clamping seat is provided on the outer side wall of the protruding portion;

[0017] That is, the buckling contact between the first fastener and the second fastener is limited and fixed by the clamping groove and the clamping seat, improving the stability of the seal itself.

[0018] A buffer washer is also provided between the first fastener and the second fastener. The buffer washer can offset the situation of loose buckling caused by the tolerance generated in the production process of the fastener.

[0019] Further, the sealing ring layer is arranged between the first through hole and the second through hole in any one of the following ways:

[0020] The sealing ring layer is fixedly connected above the first through hole;

[0021] The sealing ring layer is fixedly connected below the second through hole;

[0022] The sealing ring layer is an independent sealing ring, and the sealing ring layer is clamped between the first through hole and the second through hole by the buckling of the first fastener and the second fastener.

[0023] Further, it further includes a gland, and the gland is provided with an embedded portion, and the embedded portion is embedded in the through hole. The gland preferably adopts a rubber plug.

[0024] Further, the gland is separately provided or connected to the sealing assembly through a soft connecting member.

[0025] Further, both the first fastener and the second fastener are circular.

[0026] Further, the sealing ring layer is made of silica gel.

[0027] The present application also provides a feces collection bag, with a bag mouth provided above the feces collection bag, and the above-mentioned sealing assembly is also installed on the feces collection bag;

[0028] The first fastener is placed on the outer side of the feces collection bag, and the second fastener is placed on the inner side of the feces collection bag for fastening.

[0029] Further, after fastening, the edge of the through hole of the sealing ring layer inclines towards the inside of the feces collection bag. On the one hand, it increases the sealing effect of preventing the outflow of excrement, and on the other hand, it can play a certain cleaning effect on the tube wall when pulling out the rectal administration tube.

[0030] The present application also provides an enema auxiliary appliance, including the above-mentioned feces collection bag, and also including a feces collection bag fixing device. The feces collection bag fixing device includes a fixing seat, with an excretion hole provided in the middle of the fixing seat, and at least two sides around the excretion hole are provided with limiting protrusions.

[0031] Further, under the condition of air filling, the diameter of the fixing waist ring in the upper part of the feces collection bag is smaller than that of the upper and lower parts. When fixing with the fixing seat, the bag mouth passes through the excretion hole and turns outwards, the fixing waist ring is located at the excretion hole, and the sealing assembly is arranged below the fixing waist ring.

[0032] Further, the fixing seat includes an opposite contact surface and a separation surface, and the limiting protrusions are arranged on the contact surface. Below the separation surface is the bag body of the feces collection bag, and the contact surface contacts the patient's perianal area.

[0033] Further, it also includes a front connecting belt and a rear connecting belt. One end of the front connecting belt and the rear connecting belt are respectively connected to the front and rear sides of the fixing seat. The front connecting belt and the rear connecting belt can be fixed to the waist belt or connected to other force-applying components.

[0034] The present application also provides an assembly method for the enema auxiliary appliance, including the following steps

[0035] S1: Pass one end of the bag mouth of the feces collection bag through the excretion hole of the fixing seat, and the passing direction is from the separation surface to the contact surface. The part above the fixing seat is the connecting part, and the part below the fixing seat is the collection part;

[0036] S2: Turn the bag mouth of the connecting part in the opposite direction so that the outer wall of the connecting part closely adheres to the contact surface of the fixing seat or the cushion layer on the contact surface;

[0037] S3: By tightening the front connecting belt and / or the rear connecting belt, make the inner wall of the connecting part closely adhere to the skin or the cushion layer on the skin.

[0038] The feces collection bag passes through the excretion hole, with a part of the bag wall serving as the lining of the excretion hole and a part being directly or indirectly clamped around the anus through the contact surface. Therefore, all the contact surfaces of excreta and the drug (vaseline) are located on the inner wall of the feces collection bag, which effectively isolates the fixing seat and facilitates the reuse of the fixing seat. The disposable item is only the feces collection bag, effectively reducing the usage cost for patients.

[0039] This application also provides an enema excreta collection method, which uses the above enema auxiliary appliance.

[0040] The method includes the following steps.

[0041] S1: Use the sealing component to isolate the delivery section and the administration section of the rectal administration tube.

[0042] S2: Install a feces collection bag on the sealing component to collect excreta.

[0043] S3: After completing the enema operation, pull out the rectal administration tube, cover the rubber plug, and remove the feces collection bag for subsequent treatment after excretion.

[0044] The beneficial effects of the present invention are as follows:

[0045] 1. By using the sealing component, the sealing ring layer made of silica gel is used to isolate the delivery section and the administration section of the rectal administration tube, improving the sealing effect and isolation performance. The administration tube can move back and forth in the through hole, which not only avoids affecting the pushing of the medicine delivery tube to deliver medicine, but also provides a basic condition for connecting the collection bag on the sealing component.

[0046] 2. Install a feces collection bag on the sealing component to directly excrete excreta into the feces collection bag. This method can effectively collect excreta and reduce the difficulty of subsequent treatment.

[0047] 3. After fixing the disposable feces collection bag at the patient's anus, enema operation and excreta collection can be conveniently carried out. Medical staff can insert the rectal administration tube into the patient's anus through the medicine administration nozzle, and there will be no leakage of excreta during the enema process. After the enema is completed, the patient can excrete feces into the feces collection bag by himself.

[0048] After passing through the excretion hole, the bag mouth of the feces collection bag is turned backward and closely adheres to the contact surface, without falling off, and plays a role in isolating feces from the entire fixing seat, enabling the fixing seat to remain clean and reusable, and reducing the usage cost.

[0049] 4. The sealing component adopts a first fastener and a second fastener that are mutually buckled. Through the limit fixation of the card slot and the card seat, the stability and reliability of the seal are improved. In addition, the buffer gasket can offset problems such as loose buckling caused by tolerances during the production process to ensure the sealing effect.

[0050] After the enema operation is completed, gently pull out the rectal administration tube and cover the rubber stopper. After excretion is completed, remove the feces collection bag for subsequent processing, which can reduce cross-infection and environmental pollution problems during the processing.

[0082] Embodiment Four:

[0083] An enema excrement collection method uses the above-mentioned enema auxiliary appliance;

[0084] The method includes the following steps.

[0085] (1)After the enema administration, the patient needs to lie flat to defecate. In order to prevent the buttocks from pressing the feces collection bag and making it unable to collect feces, an inflatable gasket is additionally configured and placed under the patient's buttocks to keep the anal area of the buttocks suspended. On the one hand, it prevents the feces collection bag from being crushed and unable to collect feces, and on the other hand, it prevents pressure sores from occurring at the sacrococcygeal area.

[0086] (2)Fasten the fixing belt around the patient's waist and adjust the tightness.

[0087] (3)Connect the front connecting belt with the rear connecting belt 17.

[0088] The wearing of the collection bag and the fixing seat can refer to the specific implementation part and the drawings of the instruction manual of a defecation and perianal care appliance with the publication number CN 216417476 U and the name of a defecation and perianal care appliance, and the cotton pad therein is introduced for supporting use.

[0089] When assembling the feces collection bag and the fixing seat, the following method is adopted: Pass one end of the bag mouth of the feces collection bag through the excretion hole 15 of the fixing seat 14, and the passing direction is from the isolation surface to the contact surface. The part above the fixing seat 14 is the connecting part, and the part below the fixing seat is the collection part; the length of the extended connecting part is greater than the width of the fixing seat 14 from the center to the outer edge.

[0090] S2: Turn the connecting part reversely so that the outer wall of the connecting part closely adheres to the contact surface or the cushion layer of the contact surface of the fixing seat (14).

[0091] S3: By tightening the front connecting belt and / or the rear connecting belt (17), make the inner wall of the connecting part closely adhere to the skin or the cushion layer on the skin.

[0092] Considering that the patient's excrement is a mixture of feces and enema medicine, a cotton pad is added as a cushion layer, and it is better to smear vaseline to achieve a better sealing and leakage prevention effect.

[0093] (4)Put the feces collection bag on the excretion hole of the rear connecting belt 17.

[0094] (5)Connect the front connecting belt with the fixing belt, and the patient maintains the left lateral lying position.

[0095] (6)Slowly insert the rectal administration tube through the administration nozzle on the feces collection bag.

[0096] (7)Slowly insert the administration tube into the patient's anus to an appropriate position.

[0097] (8)Connect the rear connecting belt 17 with the fixing belt, adjust the position until the anus is aligned with the center of the excretion hole, and adjust the front and rear connecting belts 17 to make the excretion hole closely adhere to the anus.

[0098] (9)Gently pull out the excess length of the administration tube and maintain the depth of enema in the anus.

[0099] (10) Stretch the outer opening of the feces collection bag as much as possible in all directions to prevent the excretion hole from being blocked and affecting the feces collection effect.

[0100] (11) Start enema administration.

[0101] (12) After the enema administration is completed, pull out the administration tube and throw it away, and cover the rubber stopper 8 of the administration nozzle.

[0102] (13) Help the patient lie flat and start defecating. Check whether the anus is located at the center of the middle hole of the inflatable gasket and whether the feces collection bag is crushed by the buttocks.

[0103] (14) After defecation is completed, remove the feces collection bag and throw it away.

[0104] Precautions

[0105] If feces overflows during feces collection, the reasons are:

[0106] (1) The front and rear connecting bands 17 are not adjusted to the proper tightness, so that the excretion hole does not closely adhere to the perianal skin.

[0107] (2) The anus is not aligned with the center of the excretion hole.

[0108] (3) The anus is not located at the center of the inflatable gasket, and the buttocks crush the feces collection bag.

[0109] (4) The inflatable gasket is not fully inflated, resulting in the buttocks sinking and crushing the feces collection bag.

[0110] (5) Before installing the feces collection bag for each enema, first tighten the rubber stopper 8 of the administration nozzle and blow air to check whether the feces collection bag has air leakage.
