Description

Technical Field

[0001] This invention relates to the field of medical and nursing device technology, and in particular to an enema device with controllable squeezing function. Background Technology

[0002] Enemas are a common clinical medical and nursing procedure, mainly used for bowel cleansing, drug administration, and constipation relief. The core of enemas is the precise and safe injection of enema solution into the patient's intestines. Traditional enema devices often use gravity-feed enemas or simple manual squeeze enemas. The delivery pressure of the enema solution is difficult to control. When relying on manual squeezing of the reservoir, the pressure depends entirely on the operator's experience. Excessive pressure can damage the intestinal mucosa, while insufficient pressure cannot guarantee smooth injection, affecting the enema's effectiveness. Adjusting the enema solution flow rate is also inconvenient. Existing devices often use simple clamp controls with low precision and cannot accurately position the flow rate, easily leading to sudden changes in flow that can cause patient discomfort. Furthermore, the infusion tubing length is fixed and cannot be flexibly adjusted according to patient position or operating distance, resulting in poor operational convenience.

[0003] Therefore, there is an urgent need for an enema device with a reasonable structure, controllable extrusion pressure, precise flow regulation, convenient operation, and high safety and reliability to solve the problems existing in the current technology. Summary of the Invention

[0004] The purpose of this invention is to provide an enema device with controllable squeezing function, which enables real-time monitoring and controllable adjustment of enema pressure, precise control of enema flow rate, and flexible adaptation of infusion tube length. At the same time, it improves the sealing performance and operational stability of the device, ensures the safety and effectiveness of enema operation, and reduces the operational difficulty for nursing staff.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0006] An enema device with controllable squeezing function includes a reservoir, a squeezing balloon, and an enema cannula;

[0007] The storage bottle includes a bottle body and a removable cap. The bottle body is a hollow cavity with an open top. The outer wall of the bottle body is provided with a capacity scale to facilitate observation of the remaining amount of enema fluid. The removable cap is installed on the open end of the bottle body by threads. A sealing gasket is provided at the connection between the removable cap and the bottle body to further enhance the sealing performance and prevent leakage of the enema fluid.

[0008] The detachable bottle cap is equipped with a one-way air inlet valve and a one-way liquid outlet valve. The two valves are independent of each other and both communicate with the internal cavity of the storage bottle. The one-way air inlet valve only allows gas to enter the storage bottle from the outside, and the one-way liquid outlet valve only allows the enema fluid in the storage bottle to be output outward, so as to avoid gas backflow or enema fluid backflow and ensure the safety of enema operation.

[0009] The air outlet of the squeezing airbag is equipped with a pressure air tube, and the other end of the pressure air tube is detachably connected to a one-way air inlet valve, which facilitates the disassembly, cleaning and disinfection of the device; by repeatedly squeezing the airbag, the operator can inject gas into the storage bottle, and use the gas pressure to push the enema fluid in the storage bottle outward, so as to realize the pressurized supply of enema fluid.

[0010] The enema cannula has a rounded arc-shaped tip to avoid damaging the intestinal mucosa during insertion. The front side wall of the enema cannula has several evenly distributed outlet holes to allow the enema fluid to be injected into the intestine evenly, reducing local impact on the intestine. The rear end of the enema cannula is equipped with an infusion tube, and the other end of the infusion tube is detachably connected to a one-way outlet valve.

[0011] The infusion tubing includes two infusion tubing sections and a telescopic tube. The telescopic tube is located between the two infusion tubing sections and is made of foldable and stretchable medical corrugated tubing, allowing for flexible adjustment of the overall length of the infusion tubing to meet the needs of different patient positions and operating distances. A protective tube is provided on the outside of the telescopic tube. The protective tube is made of medical rigid plastic and is used to protect the telescopic tube and infusion tubing from being squeezed or bent, which would affect the delivery of the enema fluid. The infusion tubing connected to the detachable bottle cap passes through the rear end of the protective tube, and the infusion tubing connected to the enema cannula passes through the front end of the protective tube and is fixedly connected.

[0012] The protective tube has a long, narrow adjustment groove on its side wall, which is set along the length of the protective tube. The adjustment groove has a telescopic sliding groove inside, which runs through the side wall of the protective tube and is perpendicular to the adjustment groove. The connection between the infusion tubing and the rear end of the telescopic tube has a telescopic sliding column. The lower end of the telescopic sliding column is fixedly connected to the connection between the infusion tubing and the telescopic tube. The upper end of the telescopic sliding column runs through the telescopic sliding groove. The adjustment groove has a fastening nut inside, which is threaded to the upper end of the telescopic sliding column. Tightening the fastening nut can fix the telescopic sliding column in any position in the adjustment groove, thereby achieving positioning after the length of the infusion tubing is adjusted and preventing the telescopic tube from extending or retracting on its own during use.

[0013] The front end of the protective tube is equipped with a control component for adjusting the flow rate of the enema fluid. The control component includes a sleeve and an adjusting ring. The sleeve is fitted onto the outside of the infusion tubing at the front end of the protective tube and is sealed to the protective tube. The adjusting ring is rotatably located on the outside of the center of the sleeve. An annular groove is provided between the adjusting ring and the sleeve to ensure that the adjusting ring can rotate flexibly and will not fall off. A control sealing plate is provided inside the sleeve. The control sealing plate is located on one side of the infusion tubing. One end of the control sealing plate is rotatably connected to the inner wall of the sleeve through a rotating shaft. The control sealing plate rotates around the rotating shaft to achieve the opening and sealing of the infusion tubing. A sealing gear is provided at the end of the control sealing plate connected to the sleeve. The sealing gear is coaxially fixedly connected to the control sealing plate. A control drive tooth is provided on the inner side wall of the adjusting ring. The control drive tooth meshes with the sealing gear. When the adjusting ring is rotated, the control drive tooth drives the sealing gear to rotate, which in turn drives the control sealing plate to rotate around the rotating shaft, thereby adjusting the diameter of the infusion tubing and controlling the flow rate of the enema fluid.

[0014] Furthermore, the movable end of the control sealing plate is provided with an adsorption magnet one, and the sleeve is provided with an adsorption magnet two corresponding to the adsorption magnet one. The adjacent ends of the adsorption magnet one and the adsorption magnet two have opposite polarities. When the control sealing plate is fixed in rotation position, the adsorption magnet one and the adsorption magnet two attract each other, thereby positioning the control sealing plate and preventing the control sealing plate from rotating on its own during use, which would cause changes in flow rate. When it is necessary to adjust the flow rate, a certain torque is applied to rotate the adjusting ring, which can overcome the attraction force of the magnets and drive the control sealing plate to rotate.

[0015] Furthermore, the outer wall of the adjusting ring is provided with an indicator arrow, and the outer wall of the sleeve is provided with a flow rate scale. The indicator arrow and the flow rate scale work together to facilitate the operator to accurately observe and adjust the flow rate of the enema fluid, thereby improving the accuracy of the operation.

[0016] Furthermore, the detachable cap is equipped with a pressure sensor, the detection end of which extends into the interior of the storage bottle to detect the gas pressure inside the bottle in real time. The detachable cap also features a touchscreen electrically connected to the pressure sensor. The sensor transmits the detected pressure signal to the touchscreen, allowing the operator to visually observe the pressure value inside the bottle and precisely control the enema pressure by adjusting the squeezing force and frequency of the airbag. The detachable cap also contains a button battery that powers the pressure sensor and touchscreen. The touchscreen includes a power switch and a pressure alarm, and a preset pressure threshold is available. When the pressure inside the bottle exceeds the threshold, the touchscreen issues an audible and visual warning to alert the operator to stop squeezing and prevent excessive pressure from damaging the intestines.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. Stable and adjustable pressure is provided by squeezing the airbag, and the pressure sensor monitors it in real time to avoid excessively high or low pressure;

[0019] 2. The infusion tubing adopts a telescopic structure design, which, together with the adjustment groove and fastening nut on the protective tube, allows for flexible adjustment of the length of the infusion tubing to suit different patient positions and operating distances. At the same time, the protective tube can effectively protect the infusion tubing, preventing it from bending or being squeezed, and ensuring the smooth delivery of the enema solution.

[0020] 3. The control unit enables precise regulation of the enema fluid flow rate. The combination of the indicator arrow and the flow scale facilitates accurate flow control. The setting of the adsorption magnet enables the positioning of the sealing plate to prevent the flow rate from changing on its own, adapting to the enema needs of different patients.

[0021] 4. All components are detachable, making them easy to clean, disinfect, and replace. Attached Figure Description

[0029] To make the content of this invention easier to understand, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0030] like Figures 1 to 2 As shown, it includes a liquid storage bottle 1, a squeeze balloon 2, and an enema tube 3;

[0031] like Figures 1-6 As shown, the storage bottle 1 includes a bottle body 11 and a removable bottle cap 12. The bottle body 11 is a hollow cavity with an open top. The outer wall of the bottle body 11 is provided with a capacity scale line to facilitate observation of the remaining amount of enema fluid. The removable bottle cap 12 is installed on the open end of the bottle body 11 by threads. A sealing gasket is provided at the connection between the removable bottle cap 12 and the bottle body 11 to further enhance the sealing performance and prevent leakage of enema fluid.

[0032] The detachable bottle cap 12 is equipped with a one-way air inlet valve 13 and a one-way liquid outlet valve 14. The two valves are independent of each other and both communicate with the internal cavity of the storage bottle 1. The one-way air inlet valve 13 only allows gas to enter the storage bottle 1 from the outside, and the one-way liquid outlet valve 14 only allows the enema fluid in the storage bottle 1 to be output outward, so as to avoid the backflow of gas or the backflow of enema fluid and ensure the safety of the enema operation.

[0033] The air outlet of the compression airbag 2 is equipped with a pressure air tube 21. The other end of the pressure air tube 21 is detachably connected to the one-way air inlet valve 13, which facilitates the disassembly, cleaning and disinfection of the device. By repeatedly squeezing the compression airbag 2, the operator can inject gas into the liquid storage bottle 1 and use the gas pressure to push the enema fluid in the liquid storage bottle 1 outward, thereby realizing the pressurized supply of the enema fluid.

[0034] The enema cannula 3 has a rounded arc-shaped front end to avoid damage to the intestinal mucosa during insertion. The front side wall of the enema cannula 3 has several evenly distributed liquid outlet holes to allow the enema fluid to be injected into the intestine evenly and reduce local impact on the intestine. The rear end of the enema cannula 3 is provided with an infusion tube 31, and the other end of the infusion tube 31 is detachably connected to the one-way outlet valve 14.

[0035] The infusion tube 31 includes two infusion tubing sections 311 and a telescopic tube 312. The telescopic tube 312 is located between the two infusion tubing sections 311. The telescopic tube 312 is made of foldable and stretchable medical corrugated tubing, which allows for flexible adjustment of the overall length of the infusion tube 31 to meet the needs of different patient positions and operating distances. A protective tube 313 is provided on the outside of the telescopic tube 312. The protective tube 313 is made of medical rigid plastic and is used to protect the telescopic tube 312 and the infusion tubing 311 to prevent them from being squeezed or bent, which would affect the delivery of the enema fluid. The infusion tubing 311 connected to the detachable bottle cap 12 passes through the rear end of the protective tube 313, and the infusion tubing 311 connected to the enema cannula 3 passes through the front end of the protective tube 313 and is fixedly connected.

[0036] The protective tube 313 has a long, narrow adjustment groove 314 on its side wall, which is set along the length of the protective tube 313. A telescopic sliding groove 315 is provided within the adjustment groove 314, penetrating the side wall of the protective tube 313 and perpendicular to the adjustment groove 314. A telescopic sliding column 316 is provided at the rear end connection of the infusion tubing 311 and the telescopic tube 312. The lower end of the telescopic sliding column 316 is fixedly connected to the connection between the infusion tubing 311 and the telescopic tube 312. The upper end of the telescopic sliding column 316 passes through the telescopic sliding groove 315. A fastening nut 317 is provided within the adjustment groove 314, which is threaded to the upper end of the telescopic sliding column 316. Tightening the fastening nut 317 can fix the telescopic sliding column 316 at any position in the adjustment groove 314, thereby achieving positioning of the infusion tubing 31 after length adjustment and preventing the telescopic tube 312 from extending or retracting on its own during use.

[0037] like Figures 2-5As shown, the front end of the protective tube 313 is provided with a control component 32 for adjusting the flow rate of the enema fluid. The control component 32 includes a sleeve 321 and an adjusting ring 322. The sleeve 321 is sleeved on the outside of the infusion tubing 311 at the front end of the protective tube 313 and is sealed to the protective tube 313. The adjusting ring 322 is rotatably located on the outside of the center of the sleeve 321. An annular groove is provided between the adjusting ring 322 and the sleeve 321 to ensure that the adjusting ring 322 can rotate flexibly and will not fall off. A control sealing plate 323 is provided inside the sleeve 321. The control sealing plate 323 is located on one side of the infusion tubing 311, and one end of the control sealing plate 323 is connected to a rotating shaft. The control sealing plate 323 is rotatably connected to the inner wall of the sleeve 321, and rotates around the pivot to achieve the opening and closing of the infusion tubing 311. The end of the control sealing plate 323 connected to the sleeve 321 is provided with a sealing gear 324, which is coaxially fixedly connected to the control sealing plate 323. The inner side wall of the adjusting ring 322 is provided with a control drive tooth 325, which meshes with the sealing gear 324. When the adjusting ring 322 is rotated, the control drive tooth 325 drives the sealing gear 324 to rotate, which in turn drives the control sealing plate 323 to rotate around the pivot, thereby adjusting the diameter of the infusion tubing 311 and controlling the flow rate of the enema fluid.

[0038] like Figure 4 and Figure 5 As shown, the movable end of the control sealing plate 323 is provided with an adsorption magnet 326, and the sleeve 321 is provided with an adsorption magnet 327 corresponding to the adsorption magnet 326. The adjacent ends of the adsorption magnet 326 and the adsorption magnet 327 have opposite polarities. When the rotation position of the control sealing plate 323 is fixed, the adsorption magnet 326 and the adsorption magnet 327 attract each other, thereby positioning the control sealing plate 323 and preventing the control sealing plate 323 from rotating on its own during use, which would cause changes in flow rate. When it is necessary to adjust the flow rate, a certain torque is applied to rotate the adjusting ring 322, which can overcome the attraction force of the magnet and drive the control sealing plate 323 to rotate.

[0039] like Figure 1 As shown, the outer wall of the adjusting ring 322 is provided with an indicator arrow 328, and the outer wall of the sleeve 321 is provided with a flow rate scale 329. The indicator arrow 328 and the flow rate scale 329 cooperate with each other to facilitate the operator to accurately observe and adjust the flow rate of the enema fluid, thereby improving the accuracy of the operation.

[0040] like Figure 1 and Figure 6As shown, the removable bottle cap 12 is equipped with a pressure detection sensor 15. The detection end of the pressure detection sensor 15 extends into the interior of the liquid storage bottle 1 to detect the gas pressure inside the liquid storage bottle 1 in real time. The removable bottle cap 12 is equipped with a touch screen 16, which is electrically connected to the pressure detection sensor 15. The pressure detection sensor 15 transmits the detected pressure signal to the touch screen 16. The operator can intuitively observe the pressure value inside the liquid storage bottle 1 through the touch screen 16, and then control the squeezing force and frequency of the squeezing airbag 2 to achieve precise control of the enema pressure. The removable bottle cap 12 is also equipped with a button battery, which powers the pressure detection sensor 15 and the touch screen 16. The touch screen 16 is also equipped with a power switch and a pressure alarm device. A pressure threshold can be preset. When the pressure inside the liquid storage bottle 1 exceeds the threshold, the touch screen 16 issues an audible and visual warning to remind the operator to stop squeezing and avoid excessive pressure that could damage the intestines.

[0041] During use, unscrew the removable cap 12, inject an appropriate amount of enema fluid into the body 11 of the storage bottle 1, and control the amount added according to the capacity scale line; tighten the removable cap 12 onto the body 11 to ensure that the sealing gasket fits tightly; connect the pressure tube 21 of the air outlet of the squeezing airbag 2 to the one-way air inlet valve 13, and connect the infusion tube 31 to the one-way liquid outlet valve 14 to complete the device assembly.

[0042] Loosen the fastening nut 317 and push the telescopic slide column 316 to slide along the adjustment groove 314 and the telescopic slide groove 315, thereby causing the telescopic tube 312 to stretch or contract, and thus adjust the overall length of the infusion tube 31 to suit the patient's position and operating distance; after adjustment, tighten the fastening nut 317 to fix the telescopic slide column 316 and realize the positioning of the length of the infusion tube 31.

[0043] Apply medical lubricant to the tip of the enema tube 3 and slowly insert it into the patient's intestine, controlling the insertion depth according to the scale lines on the enema tube 3; turn on the power switch of the touch screen 16 and preset the pressure threshold according to the patient's condition; the operator holds the compression bag 2 and slowly and repeatedly squeezes it to inject gas into the reservoir bottle 1, and the pressure in the reservoir bottle 1 gradually increases. The pressure detection sensor 15 transmits the detected pressure signal to the touch screen 16, and the operator observes the pressure value through the touch screen 16, controls the squeezing force and frequency, and keeps the pressure within a suitable range.

[0044] Rotating the adjusting ring 322 controls the drive gear 325 to drive the sealing gear 324 to rotate, which in turn drives the control sealing plate 323 to rotate around the shaft. According to the correspondence between the indicator arrow 328 and the flow scale 329, the diameter of the infusion tubing 311 is adjusted to achieve precise control of the enema fluid flow rate. When it is necessary to pause the enema, rotating the adjusting ring 322 causes the control sealing plate 323 to completely block the infusion tubing 311. At this time, the first adsorption magnet 326 and the second adsorption magnet 327 attract each other and fix the position of the control sealing plate 323. When resuming the enema, simply rotate the adjusting ring 322 in the opposite direction.

[0045] After the enema is completed, stop squeezing the air bag 2, turn the adjusting ring 322 to close the infusion tube 31, and slowly pull out the enema tube 3; disassemble all parts, clean and sterilize them at high temperature, dry them and store them for future use.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
