Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a multi-purpose enema device. Background Art

[0002] An enema device is a device used to inject irrigation fluid into the rectum. It helps patients clean the intestines, defecate, pass gas, or supply medicine from the intestines to achieve treatment and cleansing purposes. It mainly includes anal enema and colostomy enema.

[0003] A colostomy is also known as an "artificial anus". Since a colostomy has no sphincter, the patient needs to connect a stoma plate to a stoma bag to collect excrement after surgery. The stoma plate is bonded around the colostomy, but long-term bonding can cause the skin around the colostomy to develop dermatitis, eczema and other skin diseases due to lack of air permeability. The colostomy needs to be connected to a stoma bag to prevent excrement leakage. Therefore, after skin diseases occur around the stoma, the stoma plate needs to be bonded again as soon as possible after applying medicine. The medication area cannot be kept dry and breathable, resulting in poor skin recovery. Summary of the Invention

[0004] The present invention aims to provide a multi-purpose enema device which can solve the problem that skin diseases around the enterostomy cannot be recovered in time while performing enema operation.

[0005] To achieve the above-mentioned object, the present invention adopts the following technical solution: a multi-purpose enema device, comprising a liquid filling unit, a fixing unit and a retention unit, the liquid filling unit comprising an enema liquid bag and a drainage tube, the drainage tube being connected to the enema liquid bag; the fixing unit comprising a built-in catheter and a fixing assembly; the retention unit comprising a connecting seat and a convex retention piece, the convex retention piece comprising two ends, one of larger and one of smaller diameters, the end with the larger diameter being an embedded end, the end with the smaller diameter being a sealed end, and a sealing cover being detachably connected to the sealed end; the connecting seat and the convex retention piece are detachably connected, and the connecting seat is arranged on the drainage tube, and the built-in catheter is connected to the embedded end.

[0006] The beneficial effects of this solution are as follows: before performing an enema on a patient through an enterostomy, the fixing unit is first inserted into the patient's intestine through the stoma, and the embedded end of the convex retention piece is located in the stoma, the embedded end and the stoma are sealed, and the fixing unit fixes the device in the intestine, ensuring that waste liquid does not flow out of the stoma during enema;

[0007] After the enema is completed, the connecting seat and the convex retention piece are separated, and the sealing cover is connected to the sealing end to seal the stoma. Even if the convex retention piece replaces the stoma connecting bag, since the intestinal stoma is convex compared to the patient's abdomen, after the embedded end is inserted into the stoma, the sealing end will be located above the stoma, that is, the entire convex retention piece will not contact the skin around the stoma, and the skin around the stoma will no longer be squeezed and covered by the stoma base. At the same time, by applying medicine, the skin disease caused by the long-term squeezing of the stoma base can be treated, so that the multi-purpose enema device can achieve the effects of enema and replace the stoma bag for a certain period of time, so that the skin around the stoma can be breathable and treated.

[0008] At the same time, during the period when the convex-shaped retention piece remains in the stoma, the embedded end can also expand the patient's intestinal stoma to prevent the stoma from closing, thereby replacing the medical staff or the patient's own fingers in expanding the stoma.

[0009] Preferably, a regulating valve is connected to the drainage tube.

[0010] The beneficial effect of this solution is that the cutoff or flow of the saline solution in the drainage tube can be controlled by turning the regulating valve, and the flow rate of the saline solution in the drainage tube can be adjusted at the same time.

[0011] Preferably, a waste liquid bag is connected to the drainage tube, and the regulating valve is located between the waste liquid bag and the enema liquid bag.

[0012] The beneficial effects of this solution are: during the enema process, intermittent filling and draining operations can be achieved by controlling the regulating valve and the stop valve, which can not only prevent the waste liquid from flowing back or spraying, but also reduce the patient's discomfort caused by excessive pressure in the intestine during the enema process.

[0013] Preferably, the enema liquid bag is provided with scales and a handle.

[0014] The beneficial effects of this solution are: the scale line allows medical staff to record the amount of normal saline poured into the patient's intestine; the handle on the top of the enema liquid bag enables the enema liquid bag to be hung high, making the filling operation convenient.

[0015] Preferably, the fixing assembly includes a mesh bracket, a support rod and several connecting rods. The mesh bracket is connected to the built-in catheter, and the brackets in the mesh bracket are slidingly connected to each other. The support rod is located in the built-in catheter, and one end of the connecting rod is fixed to the inner wall of the mesh bracket, and the other end is slidingly connected to the support rod.

[0016] The beneficial effects of this solution are as follows: the mesh stents that are slidably connected to each other have two states: contraction and expansion. The mesh stents are connected to the built-in catheter. In the process of the support rod driving the connecting rod to slide up and down, the mesh stents can be operated to switch between the contraction and expansion states. The expanded mesh stent supports the inner wall of the intestine, which not only expands the diameter of the connection between the mesh stent and the inner wall of the intestine, so that the waste liquid in the intestine can be discharged smoothly, but also plays a role in fixing the built-in catheter, preventing the built-in catheter from slipping outward during the enema process, causing waste liquid to flow out and pollute the environment.

[0017] The umbrella-shaped connecting rod breaks up the solid excrement under the impact of physiological saline, so that the solid excrement can be discharged smoothly, thereby improving the enema effect. The broken excrement is dispersed in the waste liquid, which makes it convenient for medical staff to stop the enema in time by observing the turbidity of the discharged waste liquid at any time, thereby reducing the enema time of the patient.

[0018] Preferably, it further comprises an annular connecting block, the support rod is provided with threads, the annular connecting block is threadedly connected to the support rod, and a plurality of connecting rods are rotatably connected to the annular connecting block in an umbrella shape.

[0019] The beneficial effect of this solution is that: through the threaded connection mechanism, the annular connection block is driven to move by rotating the support rod, thereby achieving control over the contraction and expansion of the mesh bracket.

[0020] Preferably, a knob is further included, which is rotatably arranged on the sealing end, and the support rod is fixed on the knob.

[0021] The beneficial effect of this solution is that the knob is provided to control the rotation of the support rod, which is convenient for operation.

[0022] Preferably, the sum of the lengths of the internal catheter and the mesh stent is between 5 cm and 8 cm.

[0023] The beneficial effect of this solution is that, under the fixation of the mesh stent, the length of the entire multi-use filling device entering the patient's intestine is relatively short.

[0024] Preferably, a plurality of soft membranes are arranged in a dotted pattern on the outer wall of the mesh support.

[0025] The beneficial effects of this solution are: by adding a number of soft membranes evenly distributed in a dotted manner, when the mesh stent is deployed to support the inner wall of the intestine, the soft membranes can just fill in the several folds of the intestinal wall, thereby further improving the fixation effect. The soft membrane can also reduce the direct contact between the mesh stent and the inner wall of the intestine, thereby reducing the damage caused to the inner wall of the intestine by the device during the fixation process.

[0033] The following is further described in detail through specific implementation methods:

[0034] The reference numerals in the drawings of the specification include: enema liquid bag 1, handle 11, drainage tube 2, regulating valve 21, three-way valve 22, waste liquid bag 221, stop valve 222, connecting seat 3, convex retention part 4, embedded end 41, sealing end 42, snap-fit ​​groove 421, annular groove 422, built-in catheter 5, mesh bracket 6, support rod 61, annular connecting block 611, connecting rod 62, knob 63, fixing rod 631, strip groove 632, snap-fit ​​block 633, spring 634, soft membrane 7.

[0035] Example 1

[0036] Example 1 is basically as shown in the attached Figure 1-6 As shown, Figure 1 The multi-purpose enema device shown is used for enterostomy enema or anal enema. The device in this embodiment is used for enterostomy enema and includes a liquid filling unit, a fixing unit and a retention unit. The retention unit connects the liquid filling unit with the fixing unit. The fixing unit enters the intestine through the enterostomy and is used to fix the end of the device in the intestine to improve the stability of the device during the enema process.

[0037] The filling unit is used to inject the enema solution into the patient's intestine. In this embodiment, the enema solution in the enema bag 1 is physiological saline. The filling unit includes the enema bag 1 and a drainage tube 2. The drainage tube 2 is fixed to the bottom of the enema bag 1 and is connected to the inside of the enema bag 1. The enema bag 1 is made of transparent plastic material. Figure 1As shown, the enema liquid bag 1 is provided with scale lines to facilitate medical staff to record the amount of normal saline injected into the patient's intestines; a handle 11 is integrally formed on the top of the enema liquid bag 1, and the handle 11 enables the enema liquid bag 1 to be hung at a high place for easy liquid injection operation; a regulating valve 21 is sealedly connected to the drainage tube 2, and by turning the regulating valve 21, the control of whether the normal saline in the drainage tube 2 is cut off or circulated is achieved, and the flow rate of the normal saline in the drainage tube 2 can also be adjusted.

[0038] In addition, as physiological saline is continuously poured into the intestine, the pressure inside the intestine will become greater and greater. The increase in pressure will cause the waste liquid inside the intestine to reflux or spray out from the stoma, polluting medical staff and the surrounding environment. Therefore, a three-way valve 22 is also connected to the drainage tube 2. The three-way valve 22 is located below the regulating valve 21. A waste liquid bag 221 is connected to the three-way valve 22 through a thread, and a stop valve 222 is provided at the connection between the three-way valve 22 and the waste liquid bag 221. Closing the stop valve 222 can prevent the physiological saline in the drainage tube 2 from entering the waste liquid bag 221. During the process of performing enterostomy enema on the patient, intermittent filling and draining operations can be achieved by controlling the regulating valve 21 and the stop valve 222. That is, after filling with normal saline for a period of time, the regulating valve 21 is closed and the stop valve 222 is opened to discharge the waste liquid in the intestine. Then, the stop valve 222 is closed and the regulating valve 21 is opened to refill the intestine. This is repeated multiple times. This not only prevents the waste liquid from flowing back or spraying, but also reduces the patient's discomfort caused by excessive pressure in the intestine during the enema process.

[0039] Retention unit such as Figure 1 、 Figure 2 As shown, it includes a connecting seat 3 and a convex-shaped retention piece 4. The convex-shaped retention piece 4 includes two ends with a larger diameter and a smaller diameter, wherein the end with a larger diameter is an embedded end 41, and the end with a smaller diameter is a sealing end 42. The connecting seat 3 and the convex-shaped retention piece 4 are detachably connected, and the connecting seat 3 and the convex-shaped retention piece 4 are both provided with drainage channels. When the connecting seat 3 and the convex-shaped retention piece 4 are connected, the drainage channels inside the two are interconnected to ensure that physiological saline can smoothly enter the patient's intestine through the retention unit. The specific detachable connection method is: the drainage channel on the connecting seat 3 is set to a threaded channel with an internal thread, and an external thread is set on the outer wall of the sealing end 42 of the convex-shaped retention piece 4. The external thread on the sealing end 42 cooperates with the threaded channel to realize the threaded sealing connection between the connecting seat 3 and the convex-shaped retention piece 4.

[0040] The top of the connecting seat 3 is sealed and fixed to the end of the drainage tube 2 by gluing. The embedded end 41 of the convex retention piece 4 is provided with different sizes according to the different sizes of the stoma of the intestinal stoma patient to ensure that the embedded end 41 can fit with the stoma with interference and achieve a sealed connection; the sealing end 42 is also equipped with a sealing cover, which is also detachably connected to the sealing end 42 by a thread. After the enema is completed, the convex retention piece 4 is separated from the connecting seat 3, and the sealing cover is then connected to the sealing end 42 to close the stoma. Even if the convex retention piece 4 replaces the stoma connection bag, since the intestinal stoma is convex compared to the patient's abdomen, when the embedded end 41 of the convex retention piece 4 is inserted into the stoma, The sealing end 42 is located above the stoma, that is, the sealing end 42 will not contact the skin around the stoma, and the skin around the stoma will no longer be squeezed and covered by the stoma base. At the same time, by applying medicine, the skin disease caused by the long-term squeezing of the stoma base can be treated, so that the multi-purpose enema device can achieve enema and replace the stoma bag for a certain period of time, allowing the skin around the stoma to breathe and be treated; at the same time, during the period when the convex retention piece 4 is retained in the stoma, the embedded end 41 can also expand the patient's intestinal stoma to prevent the stoma from closing, thereby replacing the medical staff or the patient's own fingers to expand the stoma.

[0041] Fixed unit such as Figure 3 、 Figure 4 As shown, it includes an internal catheter 5 and a fixing assembly. The internal catheter 5 is fixed to the embedded end 41 of the convex retention piece by bonding. The fixing assembly includes a mesh bracket 6, which is fixed to the end of the internal catheter 5 away from the embedded end 41. The brackets in the mesh bracket 6 are connected by sliding to ensure that the mesh bracket 6 has two states of contraction and expansion. When the mesh bracket 6 is expanded, Figure 6 As shown, the whole is spherical; in this embodiment, the material of the built-in catheter 5 and the mesh bracket 6 are both soft stainless steel, the built-in catheter 5 and the mesh bracket 6 are integrally formed, and the sum of the lengths of the built-in catheter 5 and the mesh bracket 6 is between 5cm and 8cm.

[0042] The fixing assembly also includes a support rod 61, an annular connecting block 611, a knob 63 and a plurality of connecting rods 62. The knob 63 is rotatably connected to the bottom of the convex retention member 4, and a drainage channel is also provided in the knob 63 to ensure that the physiological saline can enter the patient's intestine through the knob 63. The specific rotation connection method is as follows: Figure 5 As shown: an annular groove 422 is formed on the surface of the sealing end 42, and the longitudinal section of the annular groove 422 is T-shaped, and the longitudinal section of one end of the knob 63 is inverted T-shaped, and the inverted T-shaped end of the knob 63 is located in the annular groove 422. At the same time, Figure 3As shown, four engaging grooves 421 are connected in the circumferential direction of the annular groove 422, and the four engaging grooves 421 are evenly distributed. A strip groove 632 is provided on the knob 63, and a engaging block 633 is provided in the strip groove. A spring 634 is connected between the engaging block 633 and the strip groove. The knob 63 can be freely rotated on the sealing end 42 by pressing the engaging block 633 into the strip groove 632. When the engaging block 633 is engaged in the engaging groove 421 by means of the spring 634, the knob 63 and the sealing end 42 are relatively fixed. A fixing rod 631 is fixed radially to the annular knob 63, and the support rod 61 is vertically fixed to the middle section of the fixing rod 631. After being fixed, the support rod 61 is located inside the built-in catheter 5. A thread is provided on the end of the support rod 61 away from the knob 63, and the annular connecting block 611 is rotatably sleeved on the support rod 61 through a threaded connection. Figure 4 As shown, one end of several connecting rods 62 is fixed to the inner wall of the mesh support 6 by hinge. The specific hinge method is as follows: a through hole is opened in the radial direction at the end of the connecting rod 62. The support of the mesh support 6 is passed through this through hole, so that the connecting rod 62 can be rotatably connected to the mesh support 6; the other end of the connecting rod 62 is rotatably connected to the annular connecting block 611. All the connecting rods 62 are distributed outward in an umbrella shape with the axial direction of the support rod 61 as the center. Figure 6 As shown, since the mesh support 6 can be expanded outward, by continuously rotating the support rod 61, under the condition that the relative position of the mesh support 6 and the support rod 61 remains unchanged, the annular connecting block 611 is continuously moved toward the end away from the knob 63 under the action of the thread. During the movement of the knob 63, the connecting rod 62 is stretched around, thereby expanding the mesh support 6 as a whole. The expanded mesh support 6 will stretch the wrinkled intestinal wall, not only expanding the diameter of the connection between the mesh support 6 and the intestinal wall, so that the waste liquid in the intestine can be discharged smoothly, but also playing a role in fixing the built-in catheter 5, preventing the built-in catheter 5 from slipping outward during the enema process, causing the waste liquid to flow out and pollute the environment. The several umbrella-shaped connecting rods 62 are broken up by the impact of the physiological saline solution, so that the solid waste can be discharged smoothly, thereby improving the enema effect. The broken waste is dispersed in the waste liquid, which can facilitate medical staff to stop the enema in time by observing the turbidity of the discharged waste liquid at any time, thus reducing the enema time of the patient.

[0043] The specific implementation process is as follows: before performing enema on the patient through the intestinal stoma, the fixing unit is first inserted into the patient's intestine through the stoma, and the embedded end 41 of the convex retention piece 4 is located in the stoma. After ensuring that the embedded end 41 is tightly connected to the stoma, the filling unit and the fixing unit are connected through the connecting seat 3.

[0044] During enema, the regulating valve 21 is first opened to allow physiological saline to be continuously poured into the patient's intestine. When a portion of waste liquid is observed to be discharged, the regulating valve 21 is closed, the input of physiological saline is suspended, and the stop valve 222 is opened to allow the waste liquid to be discharged through the three-way valve 22 and collected in the waste liquid bag 221. The stop valve 222 is then closed and the regulating valve 21 is opened. The above steps are repeated multiple times to perform intermittent operations of filling and draining liquid to prevent waste liquid from spraying out of the stoma due to excessive pressure in the intestine. At the same time, the connecting rods 62 break up the solid excrement to improve the enema effect. Medical staff can also end the enema in time by judging the turbidity of the discharged waste liquid, thereby alleviating the patient's discomfort.

[0045] After the enema is completed, the connecting seat 3 is separated from the convex retention piece, and the sealing cover is connected to the sealing end 42. At this time, the skin around the patient's stoma can be treated with medicine. The convex retention piece 4 replaces the ostomy bag to expand the stoma and prevent closure, while also allowing the skin around the stoma to recover.

[0046] Example 2

[0047] like Figure 7 The multi-purpose enema device shown is different from Example 1 in that in this embodiment, a plurality of soft membranes 7 are fixed to the mesh support 6 by bonding, the soft membranes 7 are all hemispherical, and the soft membranes 7 are evenly distributed on the outer wall of the mesh support 6 in the form of dots.

[0048] Several soft membranes 7 are evenly distributed in a dotted pattern. When the mesh stent 6 is deployed and supported on the intestinal wall, the soft membranes 7 can fill in the several folds of the intestinal wall. The soft membranes 7 not only increase the perimeter of the mesh stent 6 when deployed, thereby supporting the intestinal wall more quickly, but also allow some of the soft membranes 7 to fit into the folds of the intestinal wall, further improving the fixation effect. The soft membranes 7 also reduce direct contact between the mesh stent 6 and the intestinal wall, thereby reducing damage to the intestinal wall caused by the device during fixation. At the same time, several soft membranes 7 are fixed between the mesh stent 6 and the intestinal wall. During the enema process, some of the soft membranes 7 can also play a role in breaking up solid excrement.

[0049] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the description can be used to interpret the content of the claims.
