Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a portable enema device. Background Art

[0002] Enema is a medical procedure that involves injecting a certain amount of liquid into the rectum and colon through the anus. It is widely used in clinical and home care scenarios such as promoting defecation, intestinal gas, intestinal cleansing, and local drug delivery. Traditional enema operations mostly use a gravity-fed system, which involves hanging an enema bag and using the liquid's own gravity to slowly inject the drug into the body. However, this traditional method has many limitations in actual application, especially when used in non-professional environments.

[0003] First, in terms of liquid flow rate control, traditional enema equipment relies on the hanging height of the enema bag to adjust the flow rate, which makes it difficult to accurately control the flow rate. When the hanging position is too high, the liquid flow rate is too fast, which may cause abdominal distension, pain or even intestinal damage to the patient; and the hanging position is too low, which will cause the flow rate to be too slow, affecting the treatment effect. This problem of unstable flow rate is particularly prominent in a home environment where there is a lack of guidance from professional medical staff, which increases the difficulty and risk of operation; secondly, during the catheter insertion process, in order to reduce the discomfort and tissue damage caused by friction, it is usually necessary to apply lubricant to the surface of the catheter. In most cases, manual application is still relied upon, which is not only cumbersome to operate, but also prone to uneven application, affecting the smoothness of insertion and patient comfort; finally, when the catheter is pulled out after the enema is completed, liquid medicine or secretions may remain on the outer wall of the catheter, which is prone to dripping, causing contamination of bed sheets, clothing, etc., bringing inconvenience to the user and increasing the risk of cross-infection. Summary of the Invention

[0004] In view of this, the present invention provides a portable enema device that can solve the shortcomings of traditional enema equipment, such as difficulty in accurately controlling the flow rate of liquid during use, reliance on manual application of lubricant, and the tendency of residual liquid or secretions on the outer wall to leak and contaminate bed sheets, clothing, etc. when the catheter is pulled out.

[0028] See Figure 4 As shown, the driving mechanism includes a second motor 601, a second gear 602 and a second gear ring 603; the second motor 601 is installed inside the rotating drum 3; the second gear 602 is connected to the output shaft of the second motor 601; six second gear rings 603 are arranged in a circular shape and rotated at intervals on the right side of the rotating drum 3, and the six second gear rings 603 are respectively located in six through holes 5, and the six spiral blades 7 are respectively connected to the inner sides of the six second gear rings 603, and the six second gear rings 603 are all engaged with the second gear 602.

[0029] See Figure 5 and Figure 6 As shown, the guide mechanism includes a sleeve 1301, a connecting plate 1302 and a scale rod 1303; the sleeve 1301 is installed on the infusion tube 9; the connecting plate 1302 is connected to the sleeve 1301; the scale rod 1303 is slidably connected to the front side of the connecting plate 1302, and the scale rod 1303 is provided with a scale, and the paint frame 14 is connected to the right end of the scale rod 1303.

[0030] See Figure 6 As shown, the positioning mechanism includes a screw 1304 and a nut 1305; the screw 1304 is slidably connected to the rear side of the connecting plate 1302, the right end of the screw 1304 is connected to the paint frame 14, and a nut 1305 is threadedly provided on the screw 1304.

[0031] See Figure 5 and Figure 6 As shown, the feeding mechanism includes a storage barrel 1501, a pump 1502 and a feeding pipe 1503; the storage barrel 1501 is installed on the front side of the liquid medicine tank 1; the pump 1502 is installed at the bottom of the storage barrel 1501, and the feed port of the pump 1502 is connected to the storage barrel 1501; the feeding pipe 1503 is connected between the discharge port of the pump 1502 and the front side of the paint frame 14.

[0032] When in use, first place the medicine liquid tank 1 on the table, then add an appropriate amount of lubricant into the storage barrel 1501, then insert the catheter 12 into the right end of the infusion tube 9 from right to left, so that the catheter 12 and the infusion tube 9 are docked, and then according to the scale on the scale rod 1303, twist the nut 1305 to rotate or reverse, so that the nut 1305 moves on the screw 1304, thereby adjusting the position of the nut 1305 on the screw 1304, so as to adjust the area of ​​the outer wall of the catheter 12 that needs to be lubricated. After adjustment, start the pump 1502 to draw the lubricant in the storage barrel 1501 into the feeding pipe 1503, so that the lubricant enters the paint frame 14 through the feeding pipe 1503, so that the lubricant is sprayed out through the paint port of the paint frame 14, and at the same time push The paint frame 14 moves to the left, causing the paint frame 14 to drive the scale rod 1303, the screw rod 1304 and the nut 1305 to move to the left, so that the conduit 12 passes through the center of the paint frame 14. When the conduit 12 passes through the center of the paint frame 14, the lubricant sprayed from the paint port will be evenly sprayed on the outer wall of the conduit 12, thereby automatically and evenly spraying the lubricating oil on the outer wall of the conduit 12. When the nut 1305 moves to the left and contacts the connecting plate 1302, the connecting plate 1302 will block the movement of the nut 1305, causing the nut 1305, the screw rod 1304, the scale rod 1303 and the paint frame 14 to stop moving, thereby positioning the paint frame 14 to ensure that the paint frame 14 sprays the lubricant on the required area of ​​the outer wall of the conduit 12, and then turn off the pump 1502. Then, the catheter 12 coated with lubricant is inserted into the rectum through the patient's anus, and then the medicine is poured into the medicine tank 1, and the flow rate sensor 10 and the second motor 601 are started, so that the second motor 601 drives the second gear 602 to rotate, thereby causing the second gear 602 to drive the second gear ring 603 and the spiral blade 7 to rotate. As the medicine is poured into the medicine tank 1, the medicine in the medicine tank 1 will flow into the through hole 5 on the lower side of the rotating drum 3 through the connecting pipe 8, and the spiral blade 7 in the through hole 5 provides a driving force for the medicine, so that the medicine flows to the right into the infusion tube 9 and the catheter 12, and is finally discharged into the patient's rectum through the catheter 12. During this period, when the medicine passes through the infusion tube 9, the flow rate sensor 10 will sense the flow rate of the medicine in the infusion tube 9. When the flow rate sensor When the device 10 senses that the flow rate of the liquid medicine in the infusion tube 9 is greater than or less than a preset value (the preset value is set as: not higher than the flow rate of the liquid medicine generated by the driving force provided by the spiral blade 7 with the largest pitch, and not lower than the flow rate of the liquid medicine generated by the driving force provided by the spiral blade 7 with the smallest pitch), the flow rate sensor 10 will send a signal. After receiving the signal, the controller 11 will control the first motor 401 to drive the first gear ring 403 and the rotating drum 3 to rotate (counterclockwise rotation when viewed from left to right) or reverse (clockwise rotation when viewed from left to right) through the first gear 402, so that the rotating drum 3 drives the position of the through hole 5 to be adjusted, so that the original lowermost through hole 5 is no longer aligned with the connecting tube 8 and the infusion tube 9, so that the spiral blade 7 in the original lowermost through hole 5 no longer provides driving force for the liquid medicine.Until the rotating drum 3 drives the next through hole 5 to align with the connecting tube 8 and the infusion tube 9, so that the spiral blade 7 in the next through hole 5 continues to provide a driving force for the liquid medicine. In this way, the driving force for the liquid medicine can be provided by switching the spiral blades 7 with different pitches, thereby automatically adjusting the flow rate of the liquid medicine in the infusion tube 9 to ensure that the flow rate of the liquid medicine in the infusion tube 9 can improve the patient's comfort when it is input into the patient's rectum. After the liquid medicine is input, the flow rate sensor 10 and the second motor 601 are turned off, and then the two collection frames 18 are respectively placed on the right side of the magnetic ring 17 from the upper and lower directions, so that the collection frame 18 contacts the outer wall of the catheter 12, so that the catheter 12 is in the arc groove of the collection frame 18, and the left side of the collection frame 18 is adsorbed on the magnetic ring 17 (such as, Figure 7 As shown), the paint frame 14 is then pushed to the right, causing the paint frame 14 to drive the scale rod 1303, the screw 1304, the nut 1305, the fixing ring 16, the magnetic ring 17 and the collection frame 18 to move to the right until the collection frame 18 contacts the patient's skin. The sleeve 1301 is then pulled to the left, causing the sleeve 1301 to drive the connecting plate 1302 and the catheter 12 to move to the left, thereby causing the catheter 12 to leave the patient's anus until the catheter 12 moves to the left and leaves the center of the fixing ring 16. During this period, as the catheter 12 gradually moves to the left, the inner left wall of the collection frame 18 will push the catheter 12 The adhesion on the outer wall is scraped off and the scraped adhesion falls into the collection frame 18 for collection, thereby automatically cleaning the adhesion on the outer wall of the catheter 12 to prevent the adhesion on the outer wall of the catheter 12 from dripping and causing contamination of bed sheets or clothes. Then, as the catheter 12 continues to move to the left, the outer wall of the catheter 12 will separate from the collection frame 18. After the catheter 12 moves to the left and leaves the center of the fixed ring 16, the catheter 12 is pulled off the infusion tube 9 to the right, and the two collection frames 18 are removed from the magnetic ring 17. Then, the collection frames 18 are disassembled and the adhesion inside is cleaned.

[0033] See Figure 5 As shown, an infusion thermostat 20 is also included; the infusion thermostat 20 is installed on the infusion tube 9, and the infusion thermostat 20 can be removed from the infusion tube 9. The infusion thermostat 20 is used to heat the liquid medicine in the infusion tube 9.

[0034] By setting up the infusion thermostat 20, the infusion thermostat 20 can be clamped on the infusion tube 9 when the medicine is transported through the infusion tube 9, and then the infusion thermostat 20 is used to heat the medicine in the infusion tube 9 to ensure that the temperature of the medicine injected into the patient is appropriate, thereby improving the patient's comfort; after the medicine in the infusion tube 9 is completed, the infusion thermostat 20 is removed from the infusion tube 9.

[0035] See Figure 9As shown, a stirring mechanism is also included, which includes a third motor 21 and an agitator 22; the third motor 21 is installed on the lower side of the liquid medicine tank 1; the output shaft of the third motor 21 rotates through the bottom of the liquid medicine tank 1, and the output shaft of the third motor 21 is connected to the agitator 22, which is located on the inner side of the liquid medicine tank 1, and the agitator 22 is used to stir the liquid medicine in the liquid medicine tank 1.

[0036] By setting up a stirring mechanism, after the medicine liquid is poured into the medicine liquid tank 1, the stirrer 22 can be driven to rotate by the third motor 21, so that the stirrer 22 stirs the medicine liquid in the medicine liquid tank 1, thereby keeping the components in the medicine liquid evenly distributed, ensuring that the concentration of the medicine liquid used each time is consistent, and improving the treatment effect.
