Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular, to a constant-temperature glycerin enema warmer. Background Art

[0002] Clinically, glycerin enema is a common clinical laxative, and its usage method is to inject the liquid medicine into the rectum through the anus. In practice, to avoid discomfort caused by intestinal irritation due to too low temperature of the injected liquid medicine, the glycerin enema bottle is usually pre-soaked and heated in warm water at about 40°C. However, this method has problems such as inaccurate temperature control, low heating efficiency, cumbersome operation, and may also cause temperature fluctuations of the liquid medicine due to water temperature fluctuations. Therefore, how to develop a new-structured glycerin enema bottle heating device to overcome the above problems of the existing technical solutions is a direction that those skilled in the art need to further study. Summary of the Invention

[0003] The purpose of the present invention is to provide a constant-temperature glycerin enema warmer for realizing constant heating of the glycerin enema bottle and overcoming the problem of unstable temperature of the liquid medicine caused by the traditional heating method.

[0004] The present invention discloses a constant-temperature glycerin enema warmer, which includes:

[0005] A heating container, on which there is a receiving cavity with an open top, and the shape of the receiving cavity is configured to accommodate at least a part of the glycerin enema bottle;

[0006] A heating part, which is arranged on the inner wall of the receiving cavity and is configured to contact and heat the glycerin enema bottle placed in the receiving cavity;

[0007] A displacement device, which is arranged in the receiving cavity and connected to the heating part, and is configured to collect the temperature value of the glycerin enema bottle placed in the receiving cavity and adjust the contact surface between the glycerin enema bottle and the heating part according to the temperature value.

[0008] By adopting this technical solution: at least a part of the glycerin enema bottle is placed in the receiving cavity, and the heating part contacts and heats the glycerin enema bottle placed in the receiving cavity; at the same time, the displacement device collects the temperature value of the glycerin enema bottle placed in the receiving cavity and adjusts the contact surface between the glycerin enema bottle and the heating part according to the temperature value. Furthermore, the heating speed of the heating part on the glycerin enema bottle is adjusted, thereby realizing constant heating of the glycerin enema bottle and avoiding the problem of too high or too low temperature of the liquid medicine.

[0009] Preferably, the displacement device includes:

[0010] A helical shape memory alloy that extends in the vertical direction with its upper end pointing to the top opening;

[0011] A gear transmission mechanism, which includes a first rack coaxially connected to the lower end of the helical shape memory alloy, a first gear meshing with the first rack, a first screw coaxially installed on the first gear, and first bearing seats respectively installed at both ends of the first screw; two first sliders symmetrically installed on the first screw, two second racks respectively connected to the two first sliders; two second gears respectively meshing with the two second racks; two second screws respectively coaxially installed on the two second gears; second bearing seats respectively installed at both ends of the two second screws; second sliders respectively installed on the two second screws;

[0012] The heating part is fixedly connected to each of the second sliders as a whole.

[0013] By adopting this technical solution: at least a part of the glycerin enema bottle is placed in the accommodating cavity, and the heating part contacts and heats the glycerin enema bottle placed in the accommodating cavity; the upper end of the helical shape memory alloy contacts the glycerin enema bottle extending into the accommodating cavity. When the temperature of the glycerin enema bottle is too high, the helical shape memory alloy expands and pushes the first rack downward. The first rack drives the first gear and the first screw to rotate, and then drives the two first sliders to move along the first screw respectively. The two second racks synchronously push the two second gears to rotate, and then drive the two second screws to rotate respectively, and then synchronously push the two second sliders to rotate along the two second screws, and then drive the heating part to move in the vertical direction, so as to reduce the contact area between the heating part and the outer wall of the glycerin enema bottle, thereby achieving the effect of temperature control. When the heating work is over, the helical shape memory alloy cools and contracts, and the overall reset of the displacement device can be realized.

[0014] Preferably, the accommodating cavity includes:

[0015] An upper cavity, which is a cylindrical cavity with an open top and is configured to place at least a part of the glycerin enema bottle;

[0016] A conical cavity, the large end of which is communicated with the lower side of the upper cavity;

[0017] A lower cavity, the small end of the conical cavity is communicated with the lower cavity; a partition is provided between the conical cavity and the lower cavity;

[0018] The upper end of the helical shape memory alloy is located in the conical cavity near the upper cavity.

[0019] By adopting this technical solution: the position of the glycerin enema bottle placed is limited by the conical cavity, avoiding excessive extrusion of the spring-shaped shape memory alloy by the glycerin enema bottle, and improving the service life of the device.

[0020] Preferably, the heating part adopts an arc-shaped surface electric heating plate, an installation groove is provided on the outer wall of the heating container, and an electric socket electrically connected to the annular electric heating plate is installed on the installation groove.

[0021] By adopting this technical solution: the body of the glycerin enema bottle placed in the accommodating cavity is heated by using an electric heating method. By providing the installation groove, the problem of placing the electrical connection line of the electric socket for the moving arc-shaped surface electric heating plate is solved.

[0022] Preferably, the heating container is made of heat-insulating material.

[0023] By adopting this technical solution:

[0024] Compared with the prior art, the present invention can achieve constant heating of the glycerin enema bottle, overcome the problem of unstable liquid medicine temperature caused by the traditional heating method, and also has the advantages of simple structure and easy preparation.

[0032] Example 1, please refer to Figures 1-4 :

[0033] A constant-temperature glycerin enema warmer, which includes: a warming container 100, a warming part 200, and a displacement device.

[0034] The warming container 100 is used to place at least a part of the glycerin enema bottle 400. The warming part 200 is used to contact and warm the glycerin enema bottle 400 placed in the warming container 100. The displacement device is used to collect the temperature value of the glycerin enema bottle 400 placed in the accommodation cavity and adjust the contact surface between the glycerin enema bottle 400 and the warming part 200 according to the temperature value.

[0035] Specifically:

[0036] The warming container 100 is made of heat-insulating material as a whole. The warming container 100 is provided with an accommodation cavity with an open top. The accommodation cavity includes: an upper cavity 110, a conical cavity 120, and a lower cavity 130. The upper cavity 110 is a cylindrical cavity with an open top. The upper cavity 110 is configured to place at least a part of the glycerin enema bottle 400. (That is, the inner radius of the upper cavity 110 matches the outer radius of the bottle body of the glycerin enema bottle 400). A chute is also opened on the side wall of the upper cavity. The number and shape of the chute match the warming part 200, so that the warming part 200 is installed on the chute and can move along the chute under the action of the displacement device.

[0037] The large end of the conical cavity 120 is communicated with the lower side of the upper cavity 110. The small end of the conical cavity 120 is communicated with the lower cavity 130. A partition 140 is provided between the conical cavity 120 and the lower cavity 130. An installation groove 150 is also provided on the outer wall of the warming container 100, and an electric socket 160 is installed on the installation groove 150. A part of the lower cavity is located outside the side wall of the upper cavity.

[0038] The heating part 200 adopts an arc-shaped surface electric heating plate. The electric socket 160 is electrically connected to the arc-shaped surface electric heating plate through an electric wire, and is used to access an external power supply to realize power supply. The electric wire passes through the installation groove 150 and is connected to the arc-shaped surface electric heating plate, and the shape of the installation groove 150 is configured such that the electric wire can move relatively within the installation groove 150 along with the up and down displacement of the arc-shaped surface electric heating plate.

[0039] The displacement device includes: a spring-shaped shape memory alloy 310 and a gear transmission mechanism. Among them, the shape memory alloy is a material with obvious thermal expansion and contraction, and it can deform according to different temperatures. The spring-shaped shape memory alloy 310 extends in the vertical direction, and the upper end of the spring-shaped shape memory alloy 310 is located at a height close to the upper cavity 110 within the conical cavity 120.

[0040] The gear transmission mechanism includes a first rack 321. The upper end of the first rack 321 is coaxially connected to the lower end of the spring-shaped shape memory alloy 310. The lower end of the first rack 321 is located in the lower cavity 130 and is meshed with the first gear 322. A first screw 323 is coaxially installed on the first gear 322. The first screw 323 extends along the horizontal direction, and both ends of its rod body are installed on two first bearing seats 324. In this example, the threads of the first screws 323 on both sides of the first gear 322 are arranged in the opposite direction. Two first sliders 325 are also installed on the first screw 323 and are distributed on both sides of the first gear 322. The two first sliders 325 move towards / away from each other as the first screw 323 rotates; two second racks 326 are respectively connected to the two first sliders 325; the two second racks 326 are respectively meshed with two second gears 327; a second screw 328 is coaxially installed on each of the two second gears 327; the two second screws 328 respectively extend in the vertical direction, and both ends of the two second screws 328 are respectively installed on two groups of second bearing seats 329; second sliders 3210 are respectively installed on the rod bodies of the two second screws 328; there are two heating parts 200 in total, which are respectively fixedly connected to the respective second sliders 3210 as a whole.

[0041] In practice, its working process is as follows:

[0042] Place at least a part of the glycerin enema bottle 400 into the accommodation cavity, so that the heating part 200 contacts and heats the glycerin enema bottle 400 placed in the accommodation cavity; the upper end of the spring-shaped shape memory alloy 310 contacts the glycerin enema bottle 400 extending into the accommodation cavity. When the temperature of the glycerin enema bottle 400 is too high, the spring-shaped shape memory alloy 310 expands and pushes the first rack 321 downward. The first rack 321 drives the first gear 322 and the first screw 323 to rotate, and then drives the two first sliders 325 to move along the first screw 323 respectively. The two second racks 326 synchronously push the two second gears 327 to rotate, and then drive the two second screws 328 to rotate respectively, and then synchronously push the two second sliders 3210 to rotate along the two second screws 328, and then drive the heating part 200 to move in the vertical direction, so as to reduce the contact area between the heating part 200 and the outer wall of the glycerin enema bottle 400, thus achieving the effect of temperature control. When the heating work is over, the spring-shaped shape memory alloy 310 cools and contracts, and the overall reset of the displacement device can be realized. Through intelligent temperature control, this device solves the pain points of the traditional glycerin enema heating method, such as low efficiency, high risk, and cumbersome operation, and provides a safe, convenient and low-cost temperature management solution for intestinal drug administration.
