Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, specifically a medicinal enema bag. Background Technology

[0002] Traditional Chinese medicine enema is a treatment method that involves inserting a catheter through the rectum into the colon to infuse liquid, thereby relieving constipation and gas. It has been used clinically for many years and is a relatively good route of drug administration. It can stimulate intestinal peristalsis, soften and clear feces, and has the effects of cooling, inducing labor, diluting intestinal toxins, and reducing absorption. In addition, it can also achieve therapeutic purposes such as supplying drugs, nutrients, and water. It mainly relies on the permeability of the semi-permeable membrane of the intestinal wall to rapidly absorb the infused Chinese medicine, thereby causing a systemic therapeutic effect, especially on nearby organs such as the pelvic cavity and abdominal cavity.

[0003] Currently, existing enema bags are not convenient for observing the depth of insertion into the anus, cannot guarantee accurate suitability for patients of all body types, require repeated insertion, and make it difficult to adjust the flow rate of the medication into the patient's body, leading to severe discomfort. Furthermore, leakage from the anus is very common during self-use. Therefore, improvements and developments are needed to address these issues. Utility Model Content

[0034] Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0035] Example 1, combined with Figures 1 to 6 As shown, this embodiment provides a medicinal enema bag, including an enema bag body 1, a tubing disposed on the enema bag body 1, and a silicone graduated tube 9 disposed on the tubing. A control mechanism 5 is disposed on the tubing, which abuts against the tubing to squeeze it, thereby changing the flow rate of the medication output from the enema bag body 1 to the tubing. A leak-proof element 8 is disposed on the silicone graduated tube 9, and the leak-proof element 8 is movably disposed on the silicone graduated tube 9, and is limited to any position on the silicone graduated tube 9 by a locking element 82. A color temperature card 2 is disposed on the enema bag body 1, which allows medical personnel or patients to easily observe the temperature of the medication inside the enema bag body 1 and take timely measures to adjust the medication temperature based on the temperature displayed on the color temperature card 2.

[0036] Specifically, the catheter includes a first catheter 3 and a second catheter 7. A control mechanism 5 is disposed on the first catheter 3, and a silicone graduated tube 9 is disposed on the second catheter 7. The first catheter 3 and the second catheter 7 are connected, allowing the medication in the enema bag body 1 to flow through the first catheter 3 and the second catheter 7 into the silicone graduated tube 9. The silicone graduated tube 9 has an outlet hole 92, which allows the medication in the silicone graduated tube 9 to be output into the body. The first catheter 3 and the second catheter 7 are connected by a sealing ring 6. The two ends of the sealing ring 6 are threaded to the first catheter 3 and the second catheter 7, respectively. Sealing rings are disposed inside the sealing ring 6 corresponding to the first catheter 3 and the second catheter 7, respectively, to seal the connection between the sealing ring 6 and the first catheter 3, and the connection between the sealing ring 6 and the second catheter 7. A clip 4 is disposed on the first catheter 3, which prevents the medication flowing into the first catheter 3 from continuing to flow.

[0037] Specifically, to prevent backflow of the medication flowing into the silicone graduated tube 9, a check valve 93 is provided on the silicone graduated tube 9. The silicone graduated tube 9 forms a flow chamber communicating with the conduit. The check valve 93 is located in the flow chamber and can effectively prevent the medication flowing into the flow chamber from flowing back, thereby avoiding affecting the remaining medication in the enema bag body 1. For example, a regulating valve 10 may also be provided on the first conduit 3. The regulating valve 10 is located below the control mechanism 5 to further prevent backflow of the medication.

[0038] Specifically, to facilitate medical staff or patients to visually observe the depth of the silicone graduated tube 9 inserted into the anus, a scale line 91 is provided on the silicone graduated tube 9, which makes it easy to observe the insertion depth of the silicone graduated tube 9.

[0039] Specifically, the control mechanism 5 includes a control box 54, which is made of transparent material and is mounted on the catheter. The control box 54 can be fixedly connected to an external infusion stand. The control mechanism 5 also includes a first rotating shaft 52, a squeezing wheel 53 and a ratchet 555 respectively mounted on the first rotating shaft 52, and a stop structure 55 that cooperates with the ratchet 555 to brake the squeezing wheel 53. The squeezing wheel 53 abuts against the catheter to squeeze it, and the ratchet 555 cooperates with the stop structure 55 to restrict the movement of the squeezing wheel 53. The first rotating shaft 52 is rotatably mounted on the control box 54, and the stop structure 55 is movably mounted on the control box 54. To facilitate the rotation of the first rotating shaft 52 by medical personnel, a control wheel 51 is provided at the shaft end of the first rotating shaft 52 and located outside the control box 54. The control wheel 51 is used to drive the first rotating shaft 52 and the squeezing wheel 53 and ratchet 555 respectively mounted on the first rotating shaft 52 to rotate.

[0040] In practical applications, the first rotating shaft 52 drives the squeezing wheel 53 and the ratchet 555 to rotate. The squeezing wheel 53 generates squeezing force on the conduit, which reduces the flow rate of the liquid medicine flowing through the conduit. The ratchet 555 cooperates with the stop structure 55 to prevent the squeezing wheel 53 from continuing to rotate, thereby achieving the function of regulating the flow rate of the liquid medicine in the conduit.

[0041] Specifically, the extrusion wheel 53 includes a wheel body and extrusion blocks disposed on the wheel body for extruding the conduit. Multiple extrusion blocks are disposed, each protruding outwards from the outer circumference of the wheel body. The multiple extrusion blocks are spaced apart along the circumference of the wheel body, and the extrusion force exerted by the multiple extrusion blocks on the conduit increases sequentially. Each extrusion block is a rectangular structure with an arc-shaped end. Five extrusion blocks are disposed, spaced apart along the circumference of the wheel body. The length of the multiple rectangular extrusion blocks increases sequentially along the circumference of the wheel body, ensuring that the force exerted by each extrusion block on the first conduit 3 is different. The longest extrusion block exerts the greatest extrusion force on the first conduit 3. After being extruded by the extrusion blocks, the flow rate of the liquid medicine within the first conduit 3 decreases, thereby regulating the flow rate of the liquid medicine within the conduit.

[0042] Specifically, the stop structure 55 includes a limiting rod 552 movably mounted on the control box 54 and a stop head 554 mounted on the limiting rod 552. The stop head 554 engages with the ratchet 555 to brake the ratchet 555. The control box 54 is provided with a first fixing member 56 corresponding to the limiting rod 552. The limiting rod 552 is slidably mounted on the first fixing member 56. The first guide tube 3 is squeezed by the extrusion block. At the same time, the stop head 554 engages with the teeth of the ratchet 555 to prevent the extrusion wheel 53 from continuing to rotate, thereby limiting the extrusion wheel 53 to a fixed position.

[0043] Specifically, the limiting rod 552 is provided with an elastic element, the two ends of which abut against the stop head 554 and the control box 54, respectively. Preferably, the elastic element is a return spring 553, the two ends of which abut against the stop head 554 and the control box 54, respectively. When the stop head 554 loses external force, the return spring 553 drives the stop head 554 to return to its original position. The two ends of the return spring 553 are connected to the first fixing member 56 and the stop head 554, respectively. When the ratchet 555 rotates, the teeth of the ratchet 555 push the stop head 554 to move towards the first fixing member 56. At this time, the return spring 553 is subjected to compressive force and deforms. When the missing tooth of the ratchet 555 corresponds to the stop head 554, the return spring 553 drives the stop head 554 to return to its original position, so that the stop head 554 locks the ratchet 555, thereby braking the ratchet 555 and preventing the compression wheel 53 from continuing to rotate.

[0044] Specifically, the leakage prevention component 8 includes a base plate 81, which is fitted onto the silicone graduated tube 9. A locking component 82 passes through a hole in the base plate 81 and abuts against the silicone graduated tube 9. The locking component 82 can be a screw, with its end abutting against the outer wall of the silicone graduated tube 9 to fix the base plate 81 to the silicone graduated tube 9. When the patient uses the silicone graduated tube 9 independently, they slide the base plate 81 along the length of the silicone graduated tube 9. Based on the patient's own condition and the graduation lines 91, the base plate 81 is fixed in a suitable position on the silicone graduated tube 9, thus preventing the patient from inserting it too deeply and causing discomfort.

[0045] Specifically, a second fixing member 83 is provided on the base plate 81, a second rotating shaft 84 is provided on the second fixing member 83, and an elastic snap-fit ​​member 85 is rotatably provided on the second rotating shaft 84. The base plate 81 has a snap-fit ​​groove 811 corresponding to the elastic snap-fit ​​member 85. A detachable medical sponge 86 is provided on the base plate 81. The medical sponge 86 is sleeved on the silicone graduated tube 9. The edge of the medical sponge 86 is located in the snap-fit ​​groove 811 and is snapped into the snap-fit ​​groove 811 by the elastic snap-fit ​​member 85, so that the medical sponge 86 is fixed on the base plate 81. The medical sponge 86 can absorb the medicine liquid after it flows out during the patient's use, preventing the medicine liquid from contaminating the bedding or clothing.

[0046] In this embodiment, combined with Figure 1 As shown, medical staff use an enema bag to operate on the patient. First, the enema bag body 1 is hung in a designated position such as an IV stand. The clip 4 is opened. When a slower flow rate is needed, the control wheel 51 is rotated. The control wheel 51 drives the first rotating shaft 52 to rotate, which in turn drives the squeezing wheel 53 and ratchet 555 on the first rotating shaft 52 to rotate. The longest squeezing block on the squeezing wheel 53 exerts the greatest squeezing force on the first catheter 3. After the first catheter 3 is squeezed by the squeezing block, the flow rate of the medicine in the first catheter 3 is reduced, thereby adjusting the flow rate of the medicine in the catheter. At the same time, the stop head 554 and the toothed ratchet 555 engage to prevent the squeezing wheel 53 from continuing to rotate, thereby limiting the squeezing wheel 53 to a fixed position. The medical staff inserts the silicone graduated tube 9 into the patient's anus. The depth of insertion of the silicone graduated tube 9 can be directly observed according to the scale line 91 to avoid discomfort to the patient.

[0047] When a patient uses an enema bag, they first slide the base plate 81 along the length of the silicone graduated tube 9. Based on the patient's condition and the graduation lines 91, the base plate 81 is fixed in the appropriate position on the silicone graduated tube 9. Then, the silicone graduated tube 9 is inserted into the anus. When the appropriate depth is reached, the base plate 81 will press against the outside of the patient's anus. At this time, the medical sponge 86 can absorb the medication after it flows out during the patient's use, preventing the medication from staining the bedding or clothing. After the patient has finished using the enema bag, the medical sponge 86 can be removed from the base plate 81 for easy replacement.

[0048] Many other changes and modifications can be made without departing from the concept and scope of this utility model. It should be understood that this utility model is not limited to the specific embodiments, and the scope of this utility model is defined by the appended claims.
