Description

Technical Field

[0001] This invention relates to the medical field, and in particular to a hot compress device for clinical ophthalmology. Background Technology

[0002] Warm compresses to the eyes are a commonly used adjunctive method in ophthalmological clinical treatment and care, and have a positive effect on relieving and treating various eye diseases and symptoms. Warm compresses can promote blood circulation in the eyes, increase the oxygen and nutrient supply to eye tissues, and help relieve discomfort symptoms such as eye fatigue, dryness, redness, and swelling. At the same time, in the treatment of some eye inflammations, warm compresses can promote the absorption and resolution of inflammation.

[0003] Existing eye heating devices have certain limitations. Some devices require frequent changes of the heating medium or adjustment of the device position during the heating process, which is cumbersome and inconvenient for patients and medical staff, essentially resulting in intermittent heating. In addition, some heating devices cannot well adapt to the differences in eye contours and orbital depths among different patients, making it difficult to ensure uniform pressure on the heating site, thus affecting the comfort and effectiveness of the heating.

[0042] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0043] To make the content of this invention easier to understand, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0044] Referring to the attached drawings, an ophthalmic clinical eye heat compress device includes a headband 100, a heat compress device 200, and a constant temperature hot water device 300.

[0045] A heat compress device 200 is used to cover the eyes; the heat compress device 200 includes heat compress pouches 210, a pushing component 220, a housing 240, and a heat compress pouch moving plate 250; the housing 240 is capable of covering the eyes. Two heat compress pouches 210 are located in the housing 240, and the heat compress pouches 210 are used for contact heat compresses on the patient's eyes. The heat compress pouch moving plate 250 is fixed to the side of the heat compress pouches 210 away from the patient's eyes. The pushing component 220 is used to push the heat compress pouch moving plate 250 away from / closer to the patient's eyes, so that the heat compress pouches 210 come into contact with the patient's eyes.

[0046] The two ends of the headband 100 are fixedly connected to the outer surface of the housing 240 of the heat compress device 200, and the headband 100 is used to put the heat compress device 200 on the patient's eyes.

[0047] The constant temperature hot water device 300 is used to heat water to a set temperature.

[0048] The circulating water component 400 forms a circulating water circuit with the water tank of the constant temperature hot water device 300 and the hot compress soft bag 210 of the hot compress device 200. The hot water from the water tank of the constant temperature hot water device 300 flows through the hot compress soft bag 210 of the hot compress device 200 and finally returns to the water tank of the constant temperature hot water device 300, so that the constant temperature hot water device 300 always maintains the water temperature.

[0049] In summary, when the patient wears the hot compress device 200 on their eyes, the constant temperature hot water device 300 maintains a constant water temperature, and the pushing component 220 keeps the hot compress soft bag 210 in contact with the eyes. Compared with the prior art, this application can maintain the effect of the hot compress soft bag 210 continuously providing constant temperature hot compress to the patient's eyes while maintaining the water temperature.

[0050] Furthermore, the circulating water assembly 400 includes a water pump 410, a water supply pipe 420, and a return water pipe 430; the inlet of the water pump 410 is connected to the water tank of the constant temperature hot water device 300; the outlet of the water pump 410 is connected to the heat compress soft bag 210 through the water supply pipe 420; both ends of the return water pipe 430 are connected to the heat compress soft bag 210 and the water tank of the constant temperature hot water device 300. The water pump 410 continuously supplies water from the water tank of the constant temperature hot water device 300 to the heat compress soft bag 210, while simultaneously, some water in the heat compress soft bag 210 flows back to the water tank of the constant temperature hot water device 300.

[0051] Furthermore, the driving component 220 includes a guide component 221, an air source cylinder 222, and a linear drive component 223;

[0052] The guide assembly 221 includes a telescopic rod 2211 and an actuating cylinder 2212; wherein, the side of the hot compress bag moving plate 250 away from the hot compress soft bag 210 is fixed to the first end of the telescopic rod 2211 and to the moving end (i.e. the actuating end of its piston rod) of the actuating cylinder 2212, and the other end of the telescopic rod 2211 and the actuating cylinder 2212 are fixedly disposed inside the housing 240.

[0053] The air source cylinder 222 includes an air source housing 2221, a piston, and a piston rod 2223; the piston slides inside the air source housing 2221, the first end of the piston rod 2223 is fixedly connected to the piston, and the second end of the piston rod 2223 extends out of the air source housing 2221.

[0054] The rodless chamber of the air source housing 2221 of the air source cylinder 222 is connected to the rodless chamber of the actuator cylinder 2212 in the guide assembly 221 through a pipeline; the movement of the piston rod 2223 of the air source cylinder 222 allows the gas in the rodless chamber of the air source cylinder 222 to enter / exit the rodless chamber of the actuator cylinder 2212, which enables the piston rod of the actuator cylinder 2212 in the guide assembly 221 to drive the hot compress bag moving plate 250 closer to / away from the patient's eye.

[0055] The linear drive assembly 223 is used to drive the movement of the piston rod 2223.

[0056] Furthermore, the linear drive assembly 223 includes a motor 2231, a screw 2232, a connector 2233, a slider 2234, a connecting assembly 2235, and a moving nut 2236;

[0057] The motor 2231 is fixedly installed in the housing 240. The output end of the motor 2231 is fixedly connected to one end of the screw 2232. The motor 2231 is used to drive the screw 2232 to rotate.

[0058] The movable nut 2236 is threaded onto the outside of the screw 2232;

[0059] The movable nut 2236 is fixedly connected to the slider 2234 via the connector 2233; the slider 2234 is fixedly connected to the second end of the piston rod 2223 of the air source cylinder 222 via the connecting assembly 2235.

[0060] It should be noted that the reciprocating rotation of the motor 2231 is converted into the reciprocating linear motion of the moving nut 2236. The linear motion of the moving nut 2236 drives the piston rod 2223 of the air source cylinder 222 to move linearly through the connector 2233, the slider 2234, and the connecting assembly 2235, thereby causing the air source cylinder 222 to drive the piston rod of the actuator cylinder 2212 to extend / retract.

[0061] Furthermore, it also includes an elastic longitudinal beam 22354, a bending sensor 22355, and a controller;

[0062] The connecting assembly 2235 includes a connecting seat 22351, a rotating rod 22352, and a spring 22353;

[0063] Two connecting seats 22351 are provided; each connecting seat 22351 is rotatably provided with two rotating rods 22352; the adjacent rotating rods 22352 on the two connecting seats 22351 are rotatably connected;

[0064] The spring 22353 is located between the two connecting seats 22351, and the two ends of the spring 22353 are fixedly connected to the two connecting seats 22351 respectively.

[0065] The two connecting seats 22351 are fixedly connected to the slider 2234 and the piston rod 2223 respectively.

[0066] The elastic longitudinal beam 22354 is located on one side of the connecting assembly 2235, and the length direction of the elastic longitudinal beam 22354 is parallel to the moving direction of the connecting assembly 2235. Both ends of the elastic longitudinal beam 22354 are fixedly connected to the inner wall of the housing 240.

[0067] The detection part of the bending sensor 22355 is fixedly connected to the elastic longitudinal beam 22354; the bending sensor 22355 is used to detect whether the elastic longitudinal beam 22354 has deformed.

[0068] The controller is electrically connected to the bending sensor 22355 to obtain a signal that the elastic longitudinal beam 22354 is bending; the controller is also electrically connected to the motor 2231.

[0069] When the controller receives a signal that the elastic longitudinal beam 22354 is bending, the controller controls the motor 2231 to stop rotating.

[0070] Working principle explanation:

[0071] After the user puts on the eye heat therapy device, the motor 2231 is started to rotate forward. The motor 2231 drives the screw 2232 to rotate, causing the threaded movable nut 2236 to move linearly. The movable nut 2236 drives the piston rod 2223 of the air source cylinder 222 to move linearly through the connector 2233, the slider 2234 and the connecting assembly 2235. This allows the gas in the rodless chamber of the air source cylinder 222 to enter the rodless chamber of the actuating cylinder 2212 of the guide assembly 221, pushing the piston rod of the actuating cylinder 2212 to extend and drive the moving plate 250 of the heat therapy bag to move, so that the heat therapy soft bag 210 directly contacts the user's eyes.

[0072] Because different users have different head shapes and eye socket depths, the movement distance of the hot compress soft bag 210 needs to be adjusted accordingly to ensure that the hot compress soft bag 210 applies the same pressure to the eyes. This invention determines whether the hot compress soft bag 210 has moved into position based on the set pressure applied to the eyes. The specific principle is as follows: When the pressure of the hot compress soft bag 210 on the eyes reaches the set threshold pressure, the gas pressure in the execution cylinder 2212 becomes a fixed value, and the gas pressure in the air source cylinder 222 is also fixed. At this time, the connecting component 2235 is subject to the reaction force of the piston rod 2223 of the air source cylinder 222, the compression of the spring 22353 is unique, the connecting seats 22351 move closer to each other, and the two rotating rods 22352 rotate and connect outwards, pressing against the elastic longitudinal beam 22354, causing the elastic longitudinal beam 22354 to bend and deform. When the bending sensor 22355 detects that the elastic longitudinal beam 22354 is bent, it transmits a signal to the controller, which controls the motor 2231 to stop rotating, thereby achieving the same pressure effect of the hot compress soft bag 210 on the user's eyes.

[0073] Furthermore, it also includes an infrared sensor, which is fixed inside the housing and electrically connected to the controller;

[0074] When the heat pack 200 is placed over the user's eyes, the infrared sensor's detection end is pointed at the user's head, and the controller drives the motor to rotate forward, bringing the heat pack into contact with the user's eyes. When the heat pack 200 is removed from the user's eyes, and the infrared sensor's detection end can no longer detect the head, the controller drives the motor to rotate in reverse, and the heat pack returns to its initial position.

[0075] Furthermore, the motor is a servo motor.

[0076] The above description is merely 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 scope of protection of the present invention.
