Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a multifunctional enema tool. Background Technology

[0002] For conditions such as constipation, hemorrhoids, and anal fissures, a small-volume non-retention enema is administered before surgery to soften stool, lubricate the intestinal wall, stimulate intestinal peristalsis, promote defecation, and thus cleanse the intestines. Currently used small-volume non-retention enema products, such as mannitol and sodium phosphate enema solutions (Huili), are mostly made of soft PE material, requiring the operator to manually squeeze the enema solution into the rectum through the anus. During the enema, the operator must stabilize the patient's buttocks with one hand and squeeze the enema solution with the other.

[0003] The shortcomings of the above-mentioned technologies are as follows: First, the amount of enema fluid injected each time is uncontrollable. Excessive flow can easily lead to overflow of the enema fluid, resulting in waste and causing discomfort to the patient.

[0004] Second, the single-handed squeezing operation is laborious and easily results in residual enema fluid, which is wasted. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional enema tool that uses electric force instead of manual squeezing, which can control the amount of enema fluid injected each time, making it less likely to overflow and waste the enema fluid, and reducing patient discomfort.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: A multifunctional enema tool includes an anal tube and a housing. The housing has a bottle-holding cavity, a groove on its head end face, and a notch at the upper end of the groove. A reservoir bottle is placed inside the bottle-holding cavity, and the reservoir bottle has a chamber filled with enema fluid. The reservoir bottle has an outlet and a piston at each end, respectively. The piston is movable within the chamber, and the outlet is inserted into the groove through the notch. The anal tube has an injection port at its tail end, which is detachably connected to the outlet. The housing has a retractable push rod on its tail end face. The inner end of the push rod moves within the bottle-holding cavity. When the push rod moves the piston towards the outlet, the enema fluid is squeezed out and flows into the patient's anus through the anal tube. The housing contains gears and a control module. The gears mesh with the push rod and are driven to rotate by a motor. When the gears rotate in the forward direction, they cause the push rod to retract into the housing. When the gears rotate in the reverse direction, they cause the push rod to extend out of the housing. The control module is electrically connected to the gears. The housing is equipped with a dispensing button for controlling the push rod to retract into the housing in a measured amount and a return button for controlling the push rod to fully extend out of the housing. Both the dispensing button and the return button are coupled to the control module.

[0007] Compared with existing technologies, the multifunctional enema tool adopting the above technical solution has the following beneficial effects: I. Using the multifunctional enema tool of this utility model, medical staff insert the head end of the anal tube into the patient's anus and connect the tail end of the anal tube to the outlet of the liquid storage bottle. Then, they press the dispensing button to inject a measured amount of enema solution into the patient's anus. This makes it easy to control the amount of enema solution injected each time, reduces the risk of overflow and waste, and minimizes patient discomfort.

[0008] Second, by repeatedly pressing the dispensing button, medical staff can drain the enema fluid from the cavity, minimizing the possibility of residual enema fluid and avoiding waste. Moreover, the electric dispensing method replaces manual operation, making it simple to use.

[0009] Third, in the preferred solution, medical staff cover the bottle cavity with cap A to prevent the liquid storage bottle from falling out of the bottle cavity and improve the aesthetics; medical staff can open the bottle cavity to replace the liquid storage bottle. The liquid storage bottle is for single use, while the shell can be reused, reducing costs. In addition, the enema fluid is not likely to contaminate the bottle cavity, reducing cleaning work.

[0010] Preferably, the inner wall of the bottle cavity is equipped with a heating element for heating the liquid storage bottle. The liquid storage bottle is made of a thermally conductive material, and the outer shell is equipped with a heating button for turning the heating element on and off. Medical staff press the heating button once to start the heating element, and press it again to turn it off. Heating the enema fluid in the cavity by the heating element prevents the cold enema fluid from flowing into the patient's anus and causing discomfort.

[0011] Preferably, a temperature sensor is installed on the inner wall of the bottle cavity, and a display screen is installed on the outside of the shell. The display screen is electrically connected to the temperature sensor, and the display screen shows the temperature value of the enema fluid in the cavity. Medical staff can check the temperature of the enema fluid in the cavity through the display screen, and inject the enema fluid into the patient's anus after it has reached a suitable temperature.

[0012] Preferably, the anal cannula has an annular balloon on its outer circumferential surface at the proximal end for fixing its position within the patient's anus. An air delivery hose is located on the side of the anal cannula's distal end, with an inflation port at its end that communicates with the inner cavity of the annular balloon. An air pump and an air delivery channel are located within the housing, and an air outlet is located on the proximal end of the housing. The air delivery channel is connected to the air pump and the air outlet at both ends, respectively. Inflation of the annular balloon by the air pump causes it to expand, compressing the rectal wall and thus fixing the anal cannula in place, preventing it from prolapsed outside the anus.

[0013] Preferably, the bottle cavity opening cap is provided with cap A.

[0014] Preferably, the shell has a storage cavity for storing the anal tube, and the opening of the storage cavity is covered with a B-cap. Storing the anal tube through the storage cavity makes it convenient to carry and avoids situations where the anal tube cannot be found.

[0015] Preferably, the injection port is rotatably connected to the end of the rectal tube, and the injection port is threadedly connected to the outlet port. The inflation port is rotatably connected to the end of the air delivery hose, and the inflation port is threadedly connected to the outlet port. The threaded connection provides a high degree of sealing, making it difficult for medical staff to twist the rectal tube and air delivery hose when rotating the injection port and inflation port.

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] like Figures 1 to 7The multifunctional enema tool shown includes an anal tube 1 and a housing 2. The housing 2 has a bottle-holding cavity 20 and a slot 21 on its head end face. The upper end of the slot 21 has a notch 22. A liquid storage bottle 4 is placed in the bottle-holding cavity 20. The liquid storage bottle 4 has a cavity 40 filled with 300ml of enema fluid. The two ends of the liquid storage bottle 4 are respectively provided with a liquid outlet and a piston 42. The piston 42 is movable within the cavity 40. The liquid outlet is inserted into the slot 21 through the notch 22. The anal tube 1 has an injection port 11 at its tail end, which is detachably connected to the liquid outlet. The tail end face of the housing 2 has a retractable push rod 3. The inner end of the push rod 3 moves within the bottle-holding cavity 20. When the push rod 3 moves the piston 42 toward the liquid outlet, the enema fluid is squeezed out and flows into the patient's anus through the anal tube 1. The housing 2 contains a gear 30 and a control module. The gear 30 meshes with the push rod 3. The gear 30 is driven by a motor to rotate. When the gear 30 rotates forward, it causes the push rod 3 to retract into the housing 2. When the gear 30 rotates in the reverse direction, it causes the push rod 3 to extend out of the housing 2. The control module is electrically connected to the gear 30. The housing 2 is equipped with a handle 34. The handle 34 has a dispensing button 31 for controlling the push rod 3 to retract into the housing 2 in a measured amount and a returning button 32 for controlling the push rod 3 to fully extend out of the housing 2. Both the dispensing button 31 and the returning button 32 are coupled to the control module. Medical staff insert the head end of the rectal tube 1 into the patient's anus and connect the tail end of the rectal tube 1 to the outlet of the storage bottle 4. Then, holding the handle 34, they press the dispensing button 31 to dispense a measured amount of enema fluid into the patient's anus. This method makes it easy to control the amount of enema fluid injected each time, reduces the risk of overflow and waste, and minimizes patient discomfort. Medical staff can repeatedly press the dispensing button 31 until the enema fluid in the cavity 40 is completely drained, which reduces the likelihood of residual enema fluid and avoids waste. Moreover, the electric operation replaces the manual operation, making it simple to use.

[0026] Reference Figure 2 The housing 2 is equipped with three adjustment keys 33 for presetting the single retraction length of the push rod 3. These keys 33 are coupled to the control module and are designated as key I, key II, and key III: pressing key I retracts the push rod 3 1cm into the housing 2; pressing key II retracts it 2cm; and pressing key III retracts it 3cm. Medical personnel can select different adjustment keys 33 to preset the single retraction length of the push rod 3 as needed.

[0027] Reference Figure 5The enema cavity 20 is shaped to fit the storage bottle 4. The storage bottle 4 is inserted into the cavity 20. The opening of the cavity 20 is covered with a cap A 23, which is magnetically connected to the opening of the cavity 20. Medical staff can close the cavity 20 with cap A 23 to prevent the storage bottle 4 from detaching and to improve aesthetics. Medical staff can open the cavity 20 to replace the storage bottle 4. The storage bottle 4 is disposable, while the casing 2 is reusable, reducing costs. Furthermore, the enema fluid is less likely to contaminate the cavity 20, reducing cleaning work.

[0028] The enema fluid in the cavity 20 is equipped with a heating element 61 on its inner wall. The storage bottle 4 is made of a thermally conductive material, and the outer shell 2 has a heating button 62 for turning the heating element 61 on and off. Medical staff press the heating button 62 once to activate the heating element 61, and press it again to deactivate it. The heating element 61 heats the enema fluid in the cavity 40, preventing the cold enema fluid from flowing into the patient's anus and causing discomfort.

[0029] Reference Figure 2 and Figure 5 A temperature sensor 60 is installed on the inner wall of the bottle cavity 20, and a display screen 6 is installed on the outside of the housing 2. The display screen 6 is electrically connected to the temperature sensor 60 and displays the temperature value of the enema fluid in the cavity 40. Medical staff can check the temperature of the enema fluid in the cavity 40 through the display screen 6, and inject the enema fluid into the patient's anus after it has reached a suitable temperature.

[0030] Reference Figure 5 and Figure 6 The anal cannula 1 has an annular air bladder 13 on its outer peripheral surface at the head end and an air delivery hose 14 on its side at the tail end. The air delivery hose 14 has an inflation port 12 at its end, which communicates with the inner cavity of the annular air bladder 13. The housing 2 contains an air pump and an air delivery channel. The housing 2 has an air outlet 51 at its head end, and the air delivery channel is connected to the air pump and the air outlet 51 at both ends. Inflation of the annular air bladder 13 by the air pump causes it to compress the inner wall of the patient's rectum, thus fixing the position of the anal cannula 1 and preventing it from prolapsed outside the anus.

[0031] The housing 2 has a knob 5 for starting and stopping the air pump. The knob 5 has a pointer 50. The housing 2 has the words "Inflate" and "Stop" marked on both sides of the knob 5. When the pointer 50 of the knob 5 turns to the word "Inflate", the air pump starts to inflate. When the pointer 50 of the knob 5 turns to the word "Stop", the air pump stops to inflate.

[0032] The injection port 11 is rotatably connected to the end of the rectal tube 1, and is threadedly connected to the outlet port. The inflation port 12 is rotatably connected to the end of the air delivery hose 14, and is threadedly connected to the air outlet 51. The threaded connection provides a high degree of sealing, making it difficult for medical staff to twist the rectal tube 1 and the air delivery hose 14 when rotating the injection port 11 and the inflation port 12.

[0033] Reference Figure 3 and Figure 4 The shell 2 is provided with a storage cavity 24, which includes two compartments, each holding one anal tube 1. The opening of the storage cavity 24 has slots 27 on both sides, and the opening of the storage cavity 24 is covered with a B-cover 26. The B-cover 26 has locking strips 28 on both sides, which are inserted into the slots 27. Storing the anal tube 1 through the storage cavity 24 facilitates carrying and prevents the anal tube 1 from being lost.
