Description

Technical Field

[0001] This application relates to the field of patient hydration devices, and more specifically, to an automatic dripping device for relieving thirst. Background Technology

[0002] After many surgeries, to help patients recover faster, medical staff require that patients not drink water post-surgery. However, thirst can be very uncomfortable for patients. Usually, medical staff will offer a small amount of water (lemon water or peppermint oil) to the patient's lips or mouth to relieve thirst and soothe their emotions.

[0003] Currently, medical staff typically feed water manually with a spoon, and this manual feeding is frequently required throughout the patient's care cycle. This frequent feeding results in time-consuming, labor-intensive, and physically demanding work for medical staff.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] The purpose of this application is to provide an automatic dripping device to relieve thirst, which solves the problem in the prior art that requires medical staff to frequently feed water, resulting in time-consuming, labor-intensive, and high-labor intensity work for medical staff.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] This application provides an automatic dripping device for relieving thirst, comprising:

[0008] The water inlet chamber is equipped with a compressible cavity, which has an inlet and an outlet. The inlet is equipped with an inlet check valve, and the outlet is equipped with an outlet check valve. A liquid guide tube is connected to the outlet and is used to insert into the patient's mouth.

[0009] The elastic element connects to the inlet chamber and is used to compress the compressible chamber so that the liquid in the compressible chamber flows out unidirectionally from the outlet.

[0010] The electromagnetic component stretches the compressible cavity by magnetically engaging with the water inlet chamber.

[0011] A timer switch is electrically connected to an electromagnetic component and is used to control the energization and de-energization of the electromagnetic component.

[0012] Optionally, the water inlet chamber includes: a cover plate, with the water inlet formed on the cover plate;

[0013] Folding telescopic cover; the folding telescopic cover can be extended or retracted.

[0014] The bottom plate and the water outlet are located on the bottom plate. The two ends of the folding telescopic cover are fixedly connected to the cover plate and the bottom plate, respectively, forming a compressible cavity.

[0015] Optionally, the two ends of the elastic element are connected to the cover plate and the bottom plate respectively. The bottom plate moves toward the cover plate by the elastic force of the elastic element and compresses and folds the telescopic cover.

[0016] Optionally, the elastic element includes multiple return springs distributed along the outer side of the folding telescopic cover.

[0017] Optionally, the electromagnetic component includes a magnetic attraction part, which is disposed on the base plate;

[0018] An electromagnetic coil is located on the side of the base plate away from the cover plate and is matched with a magnetic suction part. The electromagnetic coil is electrically connected to a timer switch and is energized or de-energized by the timer switch.

[0019] Optionally, the automatic dripper also includes a housing, with a water inlet chamber disposed within the housing;

[0020] The shell also contains a water storage chamber, which is connected to the water inlet.

[0021] Optionally, the automatic dripper also includes a telescopic adjustment assembly, on which an electromagnetic element is disposed and moved to adjust the distance from the water inlet chamber.

[0022] Optionally, the telescopic adjustment assembly includes: a rack, which is movably disposed within the housing and connected to an electromagnetic component;

[0023] The gear is rotatably mounted inside the housing and meshes with the rack;

[0024] And an adjusting rod, which is connected to a gear, and by turning the adjusting rod, the gear is driven to rotate, thereby driving the rack to move the electromagnetic component to a predetermined position.

[0025] Optionally, there are two racks, and two corresponding gears are provided. The two racks are spaced apart inside the housing, and the liquid guide tube is located between the two racks.

[0026] Optionally, the adjusting rod is provided with a locking structure, which cooperates with the housing to lock the position of the adjusting rod.

[0027] The beneficial effects of the automatic dripping device for relieving thirst provided in this application are at least as follows: A compressible chamber is provided in the water inlet, through which water is introduced to fill the compressible chamber with a thirst-quenching liquid (water, lemonade, or peppermint oil). The compressible chamber is connected to a liquid guide tube via an outlet, which is inserted into the patient's mouth. Through the combined action of an elastic element and an electromagnetic element, the compressible chamber contracts or expands. When the compressible chamber contracts, a one-way valve is provided in the outlet, allowing water to flow in only one direction. The contracted compressible chamber squeezes out the thirst-quenching liquid, which enters the patient's mouth through the liquid guide tube, providing a small amount of thirst-quenching liquid to relieve the patient's thirst. When the compressible chamber expands, the one-way valve at the inlet allows water to flow in only one direction, thus replenishing the thirst-quenching liquid from the inlet. The timer switch is electrically connected to the electromagnetic component, which controls the energization and de-energization of the electromagnetic component at a predetermined time. This allows the elastic component to cooperate with the electromagnetic component to control the contraction of the compressible cavity, enabling the timely delivery of small amounts of thirst-quenching liquid into the patient's mouth. This timed water delivery eliminates the need for frequent manual feeding by medical staff, reducing their workload. Attached Figure Description

[0037] like Figure 1 , Figure 2 , Figure 3As shown, this embodiment proposes an automatic dripping device for relieving thirst, mainly comprising: a water inlet chamber 100, an elastic element 200, an electromagnetic element 300, and a timer switch 400. The water inlet chamber 100 has a compressible cavity 121, which has an inlet 111 and an outlet 131. An inlet check valve 112 is installed inside the inlet 111, and an outlet check valve 132 is installed inside the outlet 131. A guide tube 140 is connected to the outlet 131 for insertion into the patient's mouth. Specifically, one end of the water inlet chamber 100 is fixed, while the other end is movable, allowing the compressible cavity 121 to expand or contract. The elastic element 200 connects to the inlet chamber 100 and is used to compress the compressible chamber 121 so that the liquid in the compressible chamber 121 flows out unidirectionally from the outlet 131. When the compressible chamber 121 is compressed, its volume decreases, generating a squeezing force. Under the action of the squeezing force, the inlet check valve 112 closes and the outlet check valve 132 opens, allowing the thirst-quenching liquid in the compressible chamber 121 to be discharged from the outlet 131. The thirst-quenching liquid is then squeezed into the guide tube 140 and enters the patient's mouth through the guide tube 140. When the compressible chamber 121 extends, its volume increases, generating a suction force. Under the action of the suction force, the inlet check valve 112 opens and the outlet check valve 132 closes, allowing the thirst-quenching liquid to be drawn from the inlet 111 into the compressible chamber 121, thereby replenishing the thirst-quenching liquid in the compressible chamber 121. This repeated action enables automatic dripping from the infusion tube 140. When not under force, the elastic element 200 is in a compressed state, and the electromagnetic element 300 stretches the compressible cavity 121 through magnetic attraction with the water inlet chamber 100. The timer switch 400 is electrically connected to the electromagnetic element 300 and controls its energization and de-energization. Medical personnel set a predetermined time for the timer switch 400. When the timer switch 400 reaches the predetermined time, it de-energizes the electromagnetic element 300. Without energization, the electromagnetic element 300 does not generate attraction. Under the return action of the elastic element 200, the compressible cavity 121, which is in a stretched state, is compressed, thus achieving the compression function of the water inlet chamber 100. After compression, the timer switch 400 energizes the electromagnetic element 300. The energized electromagnetic element 300 generates attraction, stretching the compressible cavity 121. Simultaneously, the elastic element 200 is stretched, generating elastic force, and water is replenished to the compressible cavity 121 in this stretched state.

[0038] like Figure 2 , Figure 3As shown, this embodiment of an automatic dripping device for relieving thirst involves a compressible chamber 121 in the water inlet chamber 100. Water enters the compressible chamber 121 through the water inlet 111, filling it with a thirst-quenching liquid (water, lemonade, or peppermint oil). The compressible chamber 121 is connected to a liquid guide tube 140 through the water outlet 131, which is then inserted into the patient's mouth. Through the combined action of the elastic element 200 and the electromagnetic element 300, the compressible chamber 121 contracts or expands. When the compressible chamber 121 contracts, a one-way valve 132 is installed in the water outlet 131, allowing only one-way water flow. The contracted compressible chamber 121 squeezes out the thirst-quenching liquid, which then enters the patient's mouth through the liquid guide tube 140, providing a small amount of thirst-quenching liquid to alleviate the patient's thirst. When the compressible cavity 121 expands, the inlet 111 is equipped with a one-way valve 112, which allows water to enter in only one direction, thus replenishing the thirst-quenching liquid through the inlet 111. The timer switch 400 is electrically connected to the electromagnetic component 300, controlling its energization and de-energization at predetermined times. This causes the elastic component 200 to cooperate with the electromagnetic component 300 to control the contraction of the compressible cavity 121, enabling the timed delivery of small amounts of thirst-quenching liquid into the patient's mouth. This timed hydration eliminates the need for frequent manual feeding by medical staff, reducing their workload.

[0039] like Figure 1 , Figure 3 As shown, the automatic drip device in this embodiment further includes a housing 10, with a water inlet chamber 100 disposed within the housing 10. An elastic element 200 and an electromagnetic element 300 are also disposed within the housing 10, forming an integral structure, allowing the liquid guide tube 140 to extend beyond the housing 10 for convenient use. A water storage chamber 150 is also provided within the housing 10, connected to a water inlet 111. The water storage chamber 150 has a larger volume than the compressible chamber 121, allowing it to store a large amount of thirst-quenching liquid at once. When the compressible chamber 121 needs replenishment, it expands by extending, opening the one-way valve 112 at the water inlet 111. This connects the water storage chamber 150 to the compressible chamber 121, replenishing the compressible chamber 121. Thus, only one addition of water to the water storage chamber 150 is needed for multiple automatic drips, reducing the frequency of water replenishment for medical personnel.

[0040] like Figure 2 , Figure 3As shown, the water inlet chamber 100 of this embodiment further includes: a cover plate 110, a folding telescopic cover 120, and a base plate 130. The cover plate 110 can be snapped and fixed inside the housing 10, and the base plate 130 is movably disposed inside the housing 10. The water inlet 111 is opened on the cover plate 110, and the water outlet 131 is opened on the base plate 130. The two ends of the folding telescopic cover 120 are respectively fixedly connected to the cover plate 110 and the base plate 130, forming a compressible cavity 121. The folding telescopic cover 120 is telescopically detachable. When the base plate 130 is movable, it drives the folding telescopic cover 120 to extend and retract, thereby changing the volume of the compressible cavity 121 and realizing the compression and expansion functions of the compressible cavity 121.

[0041] like Figure 2 , Figure 3 As shown, in this embodiment, the two ends of the elastic member 200 are connected to the cover plate 110 and the bottom plate 130, respectively. The bottom plate 130 moves toward the cover plate 110 due to the elastic force of the elastic member 200, and compresses the folding telescopic cover 120. The elastic member 200 can be disposed on the outer or inner side of the folding telescopic cover 120. When the electromagnetic member 300 moves the bottom plate 130 due to its magnetic attraction, it pulls the elastic member 200 to stretch, thereby generating elastic force. Once the electromagnetic member 300 is de-energized, the bottom plate 130 moves rapidly toward the cover plate 110 under the action of the elastic force of the elastic member 200, thereby rapidly compressing the folding telescopic cover 120 and achieving the purpose of rapid liquid dripping.

[0042] like Figure 2 , Figure 3 , Figure 4 As shown, the elastic element 200 in this embodiment further includes a plurality of return springs 210, which are distributed along the outer side of the folding telescopic cover 120. Using a plurality of return springs 210 allows for uniform application of elastic force in the circumferential direction, resulting in more even force distribution when compressing the folding telescopic cover 120 and faster extrusion of the thirst-quenching liquid.

[0043] like Figure 2 , Figure 3 , Figure 4As shown, the electromagnetic component 300 in this embodiment further includes a magnetic suction part 320 and an electromagnetic coil 310. The magnetic suction part 320 can be snapped into the base plate 130 and fixed by adhesive. The electromagnetic coil 310 is disposed on the side of the base plate 130 away from the cover plate 110 and matches the magnetic suction part 320. The electromagnetic coil 310 is electrically connected to the timer switch 400 and is energized or de-energized by the timer control of the timer switch 400. The timer switch 400 is disposed on the outer wall of the housing 10, and a rechargeable battery is also disposed inside the housing 10 to power the circuit. After the electromagnetic coil 310 is energized, it generates a magnetic force that attracts the magnetic suction part 320. This magnetic force is greater than the elastic force generated by the elastic component 200 at its extreme position. By controlling the electromagnetic coil 310 through the timer switch 400, the generation of the magnetic force can be controlled, which is convenient for medical personnel to set the time.

[0044] like Figure 3 , Figure 4 As shown, the automatic dripping device of this embodiment further includes a telescopic adjustment assembly 500. An electromagnetic component 300 is mounted on the telescopic adjustment assembly 500 and moves via the telescopic adjustment assembly 500 to adjust its distance from the water inlet chamber 100. By adjusting the distance between the electromagnetic coil 310 and the bottom plate 130 of the water inlet chamber 100, the maximum extension length of the folding telescopic cover 120 can be adjusted. The greater the extension of the folding telescopic cover 120, the larger the volume of the compressible cavity 121. Therefore, by adjusting the volume of the compressible cavity 121 via the telescopic adjustment assembly 500, the amount of liquid dripped at one time can be adjusted.

[0045] It is easy to see that if the drip volume does not need to be adjusted, the electromagnetic coil 310 can be fixed inside the housing 10 by a bracket, maintaining a predetermined distance from the base plate 130.

[0046] like Figure 3 , Figure 4As shown, the telescopic adjustment assembly 500 of this embodiment further includes a rack 510, a gear 520, and an adjusting rod 530. The rack 510 is movably disposed within the housing 10 and connected to the electromagnetic component 300. The rack 510 extends along the telescopic direction of the compressible cavity 121 and has two oblong holes. Limiting posts are correspondingly provided on the housing 10, and the oblong holes are fitted into the limiting posts, thereby allowing the rack 510 to move in a directional manner. The gear 520 is rotatably disposed within the housing 10 and meshes with the rack 510. The adjusting rod 530 is connected to the gear 520, and turning the adjusting rod 530 drives the gear 520 to rotate, thereby driving the rack 510 to move the electromagnetic component 300 to a predetermined position. In the specific structure, the adjusting rod 530 can pass through the left and right sides of the housing 10. The part of the adjusting rod 530 inside the housing 10 is fixedly connected to the gear 520. So when the adjusting rod 530 is turned, the gear 520 also rotates, which in turn moves the rack 510. The moving rack 510 drives the electromagnetic coil 310 to move, thereby adjusting the distance between the coil and the base plate 130. One end of the adjusting rod 530 extends out of the housing 10 and is connected to a handle, which allows medical personnel to easily make adjustments.

[0047] like Figure 3 , Figure 4 As shown, in this embodiment, two racks 510 are provided, and two gears 520 are correspondingly provided. The two racks 510 are spaced apart inside the housing 10, and the liquid guide tube 140 is located between the two racks 510. The two racks 510 form a symmetrical structure, which makes the connection of the electromagnetic coil 310 more stable, and the force distribution is symmetrical and uniform when magnetic attraction is generated.

[0048] like Figure 1 , Figure 3 , Figure 4As shown, in this embodiment, the adjusting rod 530 is further provided with a locking structure 540. The locking structure 540 cooperates with the housing 10 to lock the position of the adjusting rod 530. When the adjusting rod 530 is turned to the predetermined position, the locking structure 540 needs to lock the position so that the electromagnetic component 300 can attract the base plate 130 to the position each time it is energized. The locking structure 540 may specifically include: a telescopic handle 541, a positioning boss 542, and a positioning groove 543. The positioning groove 543 is formed on the outer wall of the housing 10 and multiple grooves are arranged around the adjusting rod 530. The telescopic handle 541 is connected to the outer end of the adjusting rod 530 located in the housing 10. The telescopic handle 541 can move along the axial direction of the adjusting rod 530, while being relatively fixed in the circumferential direction of the adjusting rod 530 (not rotating relative to it, which can be achieved by setting a key). The positioning boss 542 is provided on the side of the telescopic handle 541 facing the housing 10 and matches the positioning groove 543. When medical staff twist the telescopic handle 541 to rotate the adjusting rod 530, they can then push the telescopic handle 541 toward the housing 10 so that the positioning boss 542 is engaged in a positioning groove 543, thus fixing the telescopic handle 541 to the housing 10 and locking the adjusting rod 530.

[0049] In summary, the automatic dripping device for relieving thirst provided in this application uses a compressible cavity to extend and retract, thereby delivering lemon water or peppermint oil into the patient's mouth at regular intervals and in measured amounts (little by little) through a delivery tube, thus relieving thirst. It can be timed and controlled, eliminating the need for medical staff to frequently manually feed water, reducing the workload of medical staff.

[0050] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
