Description

Technical Field

[0001] The invention relates to the technical field of enema devices, in particular to a household Chinese medicine retention enema device. Background Art

[0002] Pelvic inflammatory disease is a common female disease, 20% of which leave behind chronic pelvic pain, seriously affecting the quality of life of patients. The 2023 edition of the expert consensus on the integrated treatment of chronic pelvic pain in women with traditional Chinese and Western medicine clearly states: Chinese medicine retention enema reduces gastric irritation, while the liquid medicine reaches the lesion directly, improving the drug efficiency, and also reduces lesion congestion and edema, and improves the pelvic microenvironment (consensus level: 2A). On the other hand, digestive system diseases such as functional constipation and ulcerative colitis recur repeatedly, with unclear pathogenesis and poor drug treatment effects. It is currently believed that Chinese medicine retention enema can directly act on the intestines, fully absorb, and reduce the effects of oral medications on the gastrointestinal tract, liver and kidneys, making it economical and effective. However, in the fast-paced modern life, going to the hospital for Chinese medicine retention enema treatment every day is a luxury, so a simple, hygienic and safe home Chinese medicine retention enema device will be more suitable for patients to use on their own.

[0003] The existing medical enema device mainly includes a medicine storage bag, and an infusion tube is provided at the output end of the medicine storage bag. The free end of the infusion tube is inserted into the intestine from the human anus after being coated with lubricant. A valve is provided on the infusion tube to adjust the flow rate of the traditional Chinese medicine liquid. The problems with the medical enema device are: first, the medicine storage bag must be hung at a high place and rely on gravity to fall into the intestine; second, the existing infusion tube is relatively hard. Once the operator operates it improperly, two inflection points are formed at the bend after the infusion tube is bent. The inflection points are relatively sharp and can easily cause intestinal damage; third, the existing medical enema device is not intelligent enough. When used, the control of the temperature, flow rate, etc. of the traditional Chinese medicine liquid is not accurate enough. Summary of the Invention

[0004] The present invention provides a household Chinese medicine retention enema device, which improves the existing insertion end to avoid intestinal damage caused by self-operation by personnel. Secondly, the Chinese medicine liquid is transported by an infusion pump and does not need to be hung high for use, which is more suitable for household use. Thirdly, the temperature and flow rate of the Chinese medicine liquid are intelligently controlled.

[0005] The technical problem solved by the present invention is achieved by adopting the following technical solutions:

[0006] The present invention provides a household Chinese medicine retention enema device, comprising a tank body for storing Chinese medicine liquid;

[0007] An infusion pump, the input end of which is connected to the output end of the tank body, and is used to pump the liquid medicine inside the tank body;

[0008] The infusion tube is provided at the output end of the infusion pump and is used to guide the liquid medicine into the human intestine;

[0009] An insertion end is provided on the side of the infusion tube away from the infusion pump. The insertion end has an inner and outer double-layer structure. The outer layer structure of the insertion end is a flexible layer with a Shore A value of 0-10A, and the inner layer structure of the insertion end is a supporting inner layer with a Shore A value gradually increasing from away from the infusion pump to close to the infusion pump. The smallest Shore A value of the supporting inner layer is 60A, and the largest part is 80A.

[0010] Preferably, the Shore A value of the supporting inner layer varies uniformly along its axial direction.

[0011] Preferably, the Shore A value of the supporting inner layer changes in stages along its axial direction.

[0012] Preferably, adsorption micropores are provided on the flexible layer.

[0013] Preferably, the free end of the insertion end is hemispherical, and a plurality of drainage side holes are provided at a position of the insertion end close to the free end.

[0014] Preferably, the device further comprises a controller for controlling the infusion pump to pump the liquid in the tank and a remote control terminal capable of communicating with the controller.

[0015] Preferably, a flow rate sensor is provided at the output end of the infusion pump, and the output end of the flow rate sensor is connected to the input end of the controller for feeding back a flow rate signal of the drug delivery to the controller.

[0016] Preferably, a heater for heating the liquid medicine inside the tank is also provided inside the tank body, and a temperature sensor is also provided at the output end of the infusion pump. The output end of the temperature sensor is connected to the input end of the controller for providing a temperature signal to the input end of the controller. The output end of the controller is used to send a control signal, and the control signal is used to control the operation of the heater.

[0017] Preferably, a pressure sensor for monitoring the internal pressure of the intestine is provided near the free end of the insertion end, and the output end of the pressure sensor is connected to the input end of the controller. When the controller determines through the pressure sensor that the pressure inside the intestine exceeds a threshold, the controller issues a warning message.

[0018] The beneficial effect of the present invention is that, by improving the insertion end of the existing enema device, intestinal damage will not be caused when ordinary people insert the insertion end into the anal canal.

[0019] By setting up an infusion pump as the power delivery of the traditional Chinese medicine liquid, the traditional Chinese medicine liquid does not need to be hung at a high place for use during the delivery process, and is more suitable for home use.

[0020] By setting up temperature sensors, flow rate sensors, controllers, infusion pumps, and heaters, the entire enema operation process can be made more intelligent and achieve better enema effects. By setting up pressure sensors to monitor the pressure inside the intestines, an alarm can be issued when the intestinal pressure exceeds the threshold, alerting personnel to stop the enema.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0034] refer to Figure 1-Figure 4 The present invention provides a household Chinese medicine retention enema device, which includes a tank body 1, an infusion pump 2 and an infusion tube 9, wherein the input end of the infusion pump 2 is connected to the output end of the tank body 1, and the output end of the infusion pump 2 is connected to the input end of the infusion tube 9. During the enema process, the Chinese medicine liquid inside the tank body 1 sequentially flows from the inside of the tank body 1, the infusion pump 2 and the infusion tube 9 to the inside of the intestine under the power provided by the infusion pump 2. Figure 6-Figure 8 As shown, an insertion end 10 is provided on the side of the infusion tube 9 away from the infusion pump 2. The insertion end 10 is a double-layer structure of an inner and outer layer, wherein the outer layer is a relatively soft flexible layer 15, and the inner layer is a supporting inner layer 16 that is harder than the outer layer. In order for those skilled in the art to better understand the difference between the tube body part inserted into the anus in the prior art and the insertion end 10 of the present invention, the tube body part inserted into the anus in the prior art and the insertion end 10 of the present invention are respectively introduced in detail. The tube body part inserted into the anus in the prior art is made of silicone, and its Shore A value (for evaluating the degree of softness and hardness) is 70-80A, and the overall hardness is uniform. The insertion end 10 of the present invention is divided into a flexible layer 15 and a supporting inner layer 16. The Shore A value of the flexible layer 15 is 0-10A, and the Shore A value of the supporting inner layer 16 varies. The Shore A value gradually increases from away from the infusion pump 2 to close to the infusion pump 2. The Shore A value of the supporting inner layer 16 is the smallest at 60A and the largest at 80A.

[0035] Specifically, refer to Figure 9 The Shore A value of the supporting inner layer 16 can be varied as follows: Figure 9 As shown in B, the Shore A value of the supporting inner layer 16 varies uniformly along its own axial direction. The Shore A value of the supporting inner layer 16 can also be as follows: Figure 9As described in A, the infusion tube 9 changes in stages along its axial direction, and the insertion end 10 of the infusion tube 9 thus formed has a tendency to gradually harden from the direction close to the free end to the direction away from the free end. The outside of the insertion end 10 has a flexible layer 15 as a whole, so even when it is bent, it will not form a hard bending point, causing the bending point to scratch the intestine. Since the Shore A value of the supporting inner layer 16 near the free end is small, and the outer layer is covered with the flexible layer 15, it will not cause damage to the anus.

[0036] Furthermore, in order to enable the flexible layer 15 to have a better lubricating effect after being applied with lubricating liquid, adsorption micropores 17 are provided on the flexible layer 15. During the process of applying the lubricating liquid, the flexible layer 15 can be tightly gripped to deform the flexible layer 15, and the air inside the adsorption micropores 17 is discharged, generating negative pressure and adsorbing more lubricating liquid. During the process of inserting into the anus, the lubricating liquid is squeezed by the anus and can be discharged from the adsorption micropores 17, thereby reducing the friction force generated by the squeezing of the anus and acting more accurately on the position where friction is generated (the process of the adsorption micropores 17 absorbing the lubricating liquid is similar to the process of a sponge absorbing water). Specifically, after the insertion end 10 is inserted into the target position of the human intestine, tape or other fixing devices can be used to fix the infusion tube 9 to prevent the insertion end 10 from slipping.

[0037] Furthermore, the free end of the insertion end 10 is hemispherical, and a plurality of drainage side holes 13 are provided near the free end. The hemispherical shape enables the insertion end 10 to have a good breakthrough effect and is relatively smooth without causing scratches. The plurality of drainage side holes 13 can make the liquid medicine spray more evenly, and also prevent the problem that a single drainage hole is easily blocked, resulting in the inability to perform the enema operation normally.

[0038] Furthermore, in order to enable those skilled in the art to more clearly understand the concept of the Shore A value involved in the present invention, the present invention explains the Shore A value. Shore hardness A is used to judge soft silicone, wherein Shore hardness D is used to judge hard silicone. The insertion end 10 of the infusion tube 9 of the present invention is made of soft silicone, so Shore hardness A is further explained here. In order to facilitate those skilled in the art to clearly understand, five levels of Shore value are introduced here. The first is extremely soft, with a Shore A value of 0-10A, which is similar to plasticine in life and can be easily deformed. The second is soft, with a Shore A value of 20-40A, similar to an eraser, with a certain elasticity. The third is medium, with a Shore A value of 50-70A, similar to soft plastic. The fourth is hard, with a Shore A value of 80A, close to hard rubber. The fifth is extremely hard, with a Shore D value of 20D or above, similar to hard plastic, and almost no elasticity.

[0039] Furthermore, the household Chinese medicine retention enema device provided by the present invention also includes a controller 7 for controlling the infusion pump 2 to pump the medicinal liquid inside the tank body 1, and a remote control terminal 11 capable of communicating with the controller 7. When in use, the personnel sends instructions to the controller 7 through the remote control terminal 11, and the controller 7 then controls the operation of each component to achieve the adjustment of various parameters in the enema. The parameter adjustment includes the enema flow rate parameter (also referred to as the flow rate parameter) and temperature parameter (proposed below).

[0040] Furthermore, a flow rate sensor 4 is provided at the output end of the infusion pump 2 (the output end of the infusion pump 2 is the extension tube 3), and the output end of the flow rate sensor 4 is connected to the input end of the controller 7 for feeding back a flow rate signal of the drug delivery to the controller 7. The controller 7 adjusts the power of the infusion pump 2 through the flow rate signal fed back by the flow rate sensor 4, thereby achieving precise control of the flow rate parameters. Generally, the flow rate should not be adjusted too fast during enema. An excessively fast flow rate will cause a sudden increase in the pressure in the intestine, triggering a defecation reflex, and making it impossible to fully absorb the drug. At the same time, it is also easy to cause greater stimulation to the intestine in a short period of time, causing severe pain. Slow dripping can prolong the residence time of the drug in the intestine and promote drug absorption. The general drug flow rate is designed to be 3 to 5 ml per minute, and the volume of a single enema drug solution generally does not exceed 200 ml.

[0041] Furthermore, the interior of the tank body 1 is further provided with a heater 6 for heating the medicinal liquid inside the tank body 1, and the output end (extension tube 3) of the infusion pump 2 is further provided with a temperature sensor 5, the output end of the temperature sensor 5 is connected to the input end of the controller 7, for providing a temperature signal to the input end of the controller 7, and the output end of the controller 7 is used to send a control signal, and the control signal is used to control the operation of the heater 6. The controller 7 can heat the medicinal liquid inside the tank body 1 by controlling the operation of the heater 6. At the same time, the controller 7 can adjust the power of the heater 6 through the feedback of the temperature sensor 5, thereby accurately adjusting the temperature parameters. During the enema process, the temperature of the medicinal liquid is generally adjusted to the range of 38°C-41°C, which is slightly higher than the body temperature. The main reason is that the Chinese medicinal liquid will also have temperature loss during the transportation process in the infusion tube 9. In order to minimize the The temperature of the Chinese medicine liquid can be made to be 37 degrees Celsius when it reaches the inside of the intestine. Generally, the temperature of the medicine liquid is adjusted between 38°C and 41°C during the enema process (adjusted according to the ambient temperature. For example, the temperature loss during transportation in winter is large and is generally adjusted to close to 41°C. The temperature loss during transportation in summer is small and is generally adjusted to close to 38°C). If the enema liquid enters the intestine at a higher temperature (greater than 41°C), it will scald the intestinal mucosa. If the enema liquid is at a lower temperature of less than 35 degrees Celsius, intestinal peristalsis will be weakened, affecting absorption. The existing technology generally does not have the function of temperature regulation. In the later stage of enema (the enema time generally lasts 15-20 minutes), the temperature of the medicine liquid loses seriously, resulting in a greatly reduced absorption effect of the medicine liquid by the intestine. Specifically, in order to further reduce the heat loss of the Chinese medicine liquid inside the tank body 1, the tank body 1 can adopt a tank body with better thermal insulation effect.

[0042] Furthermore, during the enema process, the pressure inside the intestine will gradually increase as the enema liquid enters. In order to avoid excessive pressure inside the intestine, which may lead to mechanical damage to the intestine, water and electrolyte imbalance and other complications, a pressure sensor 14 for monitoring the pressure inside the intestine is provided near the free end of the insertion end 10. The output end of the pressure sensor 14 is connected to the input end of the controller 7. When the controller 7 determines through the pressure sensor 14 that the pressure inside the intestine exceeds the threshold, the controller 7 issues a warning message. The specific form of the warning message may be that the corresponding indicator light (not shown in the figure) flashes or the speaker (not shown in the figure) broadcasts a voice prompt.

[0043] Specifically, the tank body 1 for storing the Chinese medicine liquid is provided with a scale line 8 for indicating the volume of the Chinese medicine liquid inside. It is preferably designed with a transparent material. The controller 7 and the infusion pump 2 are both arranged at the bottom of the tank body 1. A rechargeable power supply 18 is also provided at the bottom of the tank body 1 for providing electricity. In order to prevent the insertion end 10 from entering deeper into the human body during the enema process, a flange 12 is also provided on the infusion tube 9 to prevent the insertion end 10 from entering deeper into the human body.

[0044] Furthermore, in the specific implementation process of the present invention, existing technical means can also be used in combination to assist enema operation, such as Figure 10 As shown, in order to make the infusion tube 9 have a better fixing effect, facilitate the position stability of the insertion end 10, and prevent the Chinese medicine liquid from flowing out of the anus, an inflatable sac 20 is further provided on the outer surface of the insertion end 10. The inflatable sac 20 is connected to a branch pipe 21. During the process of inserting the insertion end 10 into the anus, the inflatable sac 20 is in a non-expanded state. When the insertion end 10 is inserted into the anus, the fluid (liquid or gas) is filled into the inflatable sac 20 through the branch pipe 21, so that the inflatable sac 20 is expanded. The outer wall 20 and the side wall of the anus are pressed against each other to achieve sealing. In order to prevent the Chinese medicine liquid inside the intestine from flowing back to the tank body 1 through the infusion tube 9, a one-way valve 19 is also provided on the infusion tube. The one-way valve 19 only allows the liquid inside the infusion tube 9 to flow from the inside of the tank body 1 to the insertion end 10, thereby preventing the liquid from flowing out of the anus or flowing back from the inside of the infusion tube 9. The above expandable bladder 20 and the one-way valve 19 are conventional technical means, which should be known to those skilled in the art, so their detailed structural composition will not be elaborated in detail here.

[0045] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
