Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, in particular to a self-heating enema jar which can be used by itself. Background Art

[0002] Enema is a medical procedure that injects a certain amount of enema liquid (such as clean water, saline, drug solution, etc.) into the intestine through the anus to clean the intestine, soften stool, stimulate intestinal peristalsis or treat certain diseases. This method can help patients relieve constipation, remove harmful substances in the intestine, and provide a clear view for further examination or surgery.

[0003] Existing enema operations are generally performed using enema bags, which are usually composed of a bag body, a hanging rope, a catheter and a flow control valve. The structure is relatively simple and the enema liquid can be injected into the patient's intestines to complete the enema operation. However, there are some problems in actual use. First, in order to reduce the stimulation to the intestines and improve the comfort of the patient, the enema liquid needs to be heated to about 40 degrees. Obviously, the existing enema bag cannot heat the added enema liquid. Therefore, it is necessary to manually use a heating device to heat the enema liquid, and then use a thermometer to measure the temperature of the enema liquid for multiple times. After reaching the appropriate temperature, The enema bag is a complicated operation, which is inconvenient for medical staff and patients to use it for self-enemas. In addition, due to the poor heat preservation effect of the enema bag, the enema liquid in the bag needs to be used in time, otherwise the low-temperature enema liquid will irritate the patient's intestines and affect the enema effect. On the other hand, in order to allow the enema liquid to fully enter the intestine, the catheter of the enema bag needs to be deeply inserted into the intestine, but it is difficult to control the insertion depth of the catheter in this enema method, and the foreign body sensation caused by the catheter deep in the intestine will cause discomfort to the patient.

Through this arrangement, The upper cover 21 and the heat-insulating casing 11 can be tightly connected together, and the sealing frame 23 is composed of a neutral plate and sealing guides on the upper and lower sides. The neutral plate of the sealing frame 23 is slidably connected to the inner wall of the exhaust port 22, and the upper and lower sealing guides of the sealing frame 23 are both in contact with the end surfaces of the plate body of the upper cover 21. Through this arrangement, the sealing frame 23 can be guided so that the sealing frame 23 can only be translated. The spring 24 is fixed between the neutral plate of the sealing frame 23 and the inner wall of the exhaust port 22. Through this arrangement, the spring 24 can reset the sealing frame 23. The push blocks 55 are all arranged on the lower side of the guide blocks 25. Through this arrangement, the upward movement of the push blocks 55 can squeeze the guide blocks 25.The left and right base blocks of the heat preservation shell 11 are rotatably connected with hanging belts 16. Through this arrangement, the self-heating enema tank can be hung at a high place. The damping sleeve 32 is sleeved on the outside of the heat preservation shell 11. The inner wall of the damping sleeve 32 fits the outer curved surface of the heat preservation shell 11. Through this arrangement, the lower cover 3 can be reliably installed on the lower side of the outer shell 1. The lower hole of the heating tank 4 is fixedly connected to the conduit 7. Through this arrangement, leakage of the lower hole of the heating tank 4 can be avoided. A flow regulator is provided on the conduit 7. Through this arrangement, the flow of the conduit 7 can be controlled. flow, the infusion head 8 is inserted into the inner side of the lubricating seat 33, and the lubricating seat 33 can lubricate the infusion head 8 through this setting, so as to facilitate the insertion of the infusion head 8; the upper end of the guide rod 13 contacts the inner wall of the upper cover 21, and the guide rod 13 can have a sufficient length to guide the liquid medicine tank 5 through this setting, and a gap is set between the lower end surface of the tank body 51 and the lower inner wall of the heating tank 4, and a space is left for the lime bag to be placed, and a gap is set between the inner curved surface of the heating tank 4 and the supporting piece 53, and water is conveniently added through this setting. ;

[0031] like Figure 9-12 As shown, the infusion head 8 includes a support baffle 81, the lower side of the support baffle 81 is connected to the middle tube 82, a group of multiple annular grooves 83 arranged at equal distances are opened on the outer curved surface of the middle tube 82, connecting grooves 84 are opened between the annular grooves 83 and the inner channel of the middle tube 82, the inner sides of the annular grooves 83 are fixedly connected with elastic damping belts 85, the lower side of the middle tube 82 is connected to the cannula 86, the inner side of the cannula 86 is fixedly connected with a flow blocking member 87, and the inner side of the lower annular channel of the support baffle 81 is fixedly connected with an adhesive tape 88, so that the enema liquid entering the infusion head 8 will pass through the support baffle 81 and enter the middle tube 82, and then will be slightly blocked by the flow blocking member 87 and then enter the cannula 86, so that the enema liquid is discharged into the patient's intestine through the cannula 86, wherein the flow blocking of the flow blocking member 87 will cause part of the enema liquid to pass through the connecting grooves 84 and enter each annular groove 83. As the liquid in the annular groove 83 flows, The increase in the number of elastic damping belts 85 will cause each elastic damping belt 85 to expand outward and fit closely to the patient's anal skin. While further positioning the infusion head 8, the possibility of leakage at the insertion site can be avoided, so that the enema liquid discharged through the infusion head 8 can only flow to the deep part of the intestine; the support block piece 81, the middle tube 82 and the insertion tube 86 are fixedly connected, and the insertion tube 86 is a tapered tube structure. This arrangement facilitates the insertion of the infusion head 8 into the anus. The lower end of the insertion tube 86 is a rounded corner arrangement.

The flow blocking member 87 is composed of an outer fixed ring and an inner rubber elastic diaphragm. The inner side of the inner rubber elastic diaphragm of the flow blocking member 87 is provided with a cross opening. Through this arrangement, the flow blocking of the flow blocking member 87 will cause part of the enema liquid to enter each annular groove 83 through the connecting groove 84, thereby causing each elastic damping belt 85 to expand outward.

[0032] Workflow: The enema operation of the self-heating enema tank is as follows. For enema preparation, first remove the upper cover 2 from the outer shell 1, and then pull up the medicine tank 5 to extend the folding tube 54. At this time, put an appropriate amount of lime packs into the heating tank 4 (an appropriate amount of lime packs and water can just heat the enema liquid to a suitable temperature), and then reset the medicine tank 5 so that the guide strips 52 on both sides are sleeved on the outside of the guide rod 13, and then the guide strips 52 are embedded in the grooves 12 through the guidance of the guide rod 13. At this time, the tank body 5 1 is inside the heating tank 4, the medicine tank 5 is reset, and then a proper amount of water is added to the heating tank 4 based on the scale bar 15, and a proper amount of enema liquid is added to the medicine tank 5, and then the upper cover 2 is covered back to the upper side of the outer shell 1. At this time, the heat generated by the reaction of water and lime will cause the water to quickly heat up and fluctuate and generate a large amount of water vapor. On the one hand, the temperature rise of the water will heat the enema liquid in the medicine tank 5, and the water temperature can be observed through the temperature display bar 6. On the other hand, the rise of the water vapor is controlled by the trust piece 53. The current is limited, and the support piece 53 is pushed up, and then the upward push of the water wave is used to push the entire medicine liquid tank 5 to move upward with the guide rod 13 as the guide, so that the push blocks 55 on both sides squeeze the guide block 25, so that the guide blocks 25 on both sides drive the sealing frame 23 connected thereto to move, so that the spring 24 contracts, and the opened exhaust port 22 allows the steam to be discharged. When the water and lime react and no longer generate a large amount of steam, the medicine liquid tank 5 will move down and reset, so that the push block 55 no longer squeezes the guide block 25. At this time, the spring 24 can expand and start to push the sealing frame 23 to reset, and the exhaust port 22 is sealed by the sealing frame 23 to avoid the discharge of residual steam heat, so that the enema liquid heated in the medicine liquid tank 5 can be kept warm. At this time, the temperature display bar 6 can be used to confirm whether the temperature of the enema liquid in the medicine liquid tank 5 has reached the appropriate temperature (the temperature display bar 6 can display the temperature of the water in the heating tank 4, and the temperature of the enema liquid in the medicine liquid tank 5 is usually about 3-5 degrees lower than the external water temperature). After confirmation, the preparation operation of enema is completed;During enema operation, the entire self-heating enema tank is hung on the external rack by means of the hanging strap 16, and then the lower cover portion 3 is removed from the outer shell portion 1, and then the infusion head 8 is taken out from the lubrication seat 33 (the lubrication seat 33 groove is pre-filled with lubricating liquid, and the middle tube 82 and the cannula 86 of the infusion head 8 can be coated with lubricating liquid to facilitate insertion), and then most of the rolled-up catheter 7 is pulled out from the outer shell portion 1 by pulling the infusion head 8, and at this time, the cannula 86 and the middle tube 82 can be inserted into the patient's anus by holding the support baffle 81 of the infusion head 8 with one hand, so that the adhesive tape 88 adheres to the patient's skin and the position of the infusion head 8 is positioned, and at this time, the catheter 7 can be made to circulate through the flow regulator of the catheter 7, so that the heated enema liquid in the liquid medicine tank 5 can enter the infusion head 8 through the folding tube 54 and the catheter 7, and the enema liquid entering the infusion head 8 will pass through the support baffle 81 and enter the middle tube 82, and then will be slightly blocked by the flow blocker 87 Then, the intubation tube 86 is inserted, and the enema liquid is discharged into the patient's intestine through the intubation tube 86. The flow resistance of the flow blocking member 87 causes part of the enema liquid to enter the annular grooves 83 through the connecting groove 84. As the amount of liquid in the annular grooves 83 increases, the elastic damping belts 85 expand outwards and fit closely with the skin in the anus of the patient. While further positioning the infusion head 8, the possibility of leakage at the insertion site can be avoided, so that the enema liquid discharged through the infusion head 8 can only flow to the deep part of the intestine, so that the enema liquid input by the infusion head 8 at the anus can fully enter the intestine, thereby avoiding the discomfort caused by the catheter 7 penetrating into the intestine. After the enema is completed, since the enema liquid no longer flows in the infusion head 8, there is no enema liquid to support the expanded elastic damping belts 85. The elastic damping belts 85 will be reset and no longer fit closely with the skin in the anus. At this time, the infusion head 8 can be conveniently taken out from the anus to complete the enema operation. ;
