Technical Field

[0001] This utility model relates to the field of medical rescue technology, specifically a negative pressure suction device for rescue. Background Technology

[0002] Medical rescue refers to the process of providing timely and effective medical assistance and care in a medical setting for sudden situations or emergencies. The purpose of medical rescue is to provide timely and effective on-site assistance and care to individuals or groups to save lives, alleviate injuries and suffering, and, under medical supervision, transport the injured or sick to a hospital for further comprehensive treatment using modern transportation. A negative pressure suction device is an emergency rescue device that creates a negative pressure state at the suction head, forcing external substances towards the suction head to achieve a "suction" effect. This device, based on the principle of negative pressure suction, can quickly restore a patient's breathing and is particularly suitable for emergency situations such as suffocation, difficulty breathing, or situations requiring artificial respiration. To improve the efficiency of medical rescue, a negative pressure suction device is needed; however, existing negative pressure suction devices still have the following shortcomings:

[0003] When using existing negative pressure aspirators, the waste liquid collection bottle is not easy to disassemble and assemble quickly, and the overall size of the negative pressure aspirator is too large to carry. As a result, the use of negative pressure aspirators is relatively cumbersome, and it is not easy to quickly replace the waste liquid collection bottle according to the needs of use. This leads to a decrease in the practicality and efficiency of negative pressure aspirators. Utility Model Content

[0004] The purpose of this invention is to provide a negative pressure suction device for rescue, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a negative pressure suction device for rescue, comprising a main housing and an installation assembly. The upper end of the main housing is connected to an installation top cover. Installation assemblies are arranged on both sides inside the main housing. Each installation assembly includes an installation block, a docking groove, a receiving groove, a spring damping rod, a limiting ball, a docking block, a limiting through groove, a fixing block, and a collection bottle.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1 to 3As shown, a rescue negative pressure suction device includes a main housing 1 and a mounting assembly 3. A mounting top cover 2 is connected to the upper end of the main housing 1. The mounting assembly 3 is arranged on both sides inside the main housing 1. The mounting assembly 3 includes a mounting block 301, a docking groove 302, a receiving groove 303, a spring damping rod 304, a limiting ball 305, a docking block 306, a limiting through groove 307, a fixing block 308, and a collection bottle 309. A docking groove 302 is formed in the middle of the mounting block 301, and receiving grooves 303 are formed on both sides of the docking groove 302. A spring damping rod 304 is installed inside the receiving groove 303. The spring damping... A limiting ball 305 is installed at the front end of rod 304. A docking block 306 is connected inside the docking groove 302. Limiting through grooves 307 are opened on both sides inside the docking block 306. A fixing block 308 is installed on the upper end of the docking block 306. A liquid collection bottle 309 is provided on the outside of the fixing block 308. The internal dimensions of the docking groove 302 are adapted to the external dimensions of the docking block 306. The docking block 306 is embeddedly connected to the mounting block 301 through the docking groove 302. The spring damping rod 304 and the limiting ball 305 are vertically distributed. The limiting ball 305 is elastically connected to the receiving groove 303 through the spring damping rod 304, limiting the movement. The external dimensions of ball 305 are adapted to the internal dimensions of limiting groove 307, and the limiting ball 305 is connected to the mating block 306 through the limiting groove 307. The mounting block 301 is fixedly installed on both sides inside the main housing 1 by fastening bolts, and the spring damping rod 304 is fixedly installed in the receiving groove 303 inside the mounting block 301 with the fastening bolts. The spring damping rod 304 allows the limiting ball 305 to be elastically connected to the receiving groove 303. Simultaneously, the external dimensions of the mating block 306 at the lower end of the fixing block 308 are adapted to the internal dimensions of the mating groove 302 inside the mounting block 301, thereby allowing the ball to pass through the groove. The docking groove 302, in conjunction with the docking block 306, completes the docking and limiting of the fixing block 308 and the mounting block 301. This limits the liquid collection bottle 309, which is installed outside the fixing block 308, to be positioned between the two mounting blocks 301. The internal dimensions of the limiting through groove 307 inside the docking block 306 are adapted to the external dimensions of the limiting ball 305. Thus, the docking block 306 is fixedly installed inside the mounting block 301 through the limiting through groove 307 and the limiting ball 305, thereby fixing the liquid collection bottle 309 in place. This also improves the overall ease of disassembly and assembly of the liquid collection bottle 309 and increases the overall practicality and efficiency of the negative pressure suction device.

[0022] like Figures 1 to 3As shown, a suction assembly 4 is provided on the outside of the collection bottle 309. The suction assembly 4 includes a vacuum pump 401, a connecting pipe 402, and a liquid level sensor 403. The connecting pipe 402 is connected to the outside of the vacuum pump 401. The liquid level sensor 403 is installed on the upper end of the collection bottle 309. The suction assembly 4 also includes a buzzer 404, a connecting hose 405, and a check valve 406. The buzzer 404 is located on the left side of the liquid level sensor 403. The connecting hose 405 is connected to the upper end of the collection bottle 309, and the check valve 406 is connected to the middle of the connecting hose 405. The outer side of the vacuum pump 401 is horizontally distributed with the outer side of the collection bottle 309, and the upper surface of the vacuum pump 401 is in close contact with the lower surface of the collection bottle 309. The outer side of the buzzer 404 is horizontal with the outer side of the collection bottle 309. The vacuum pump 401 is fixedly installed inside the lower end of the main housing 1 by bolts and the buzzer 404 is fixedly connected to the collection bottle 309 by fastening bolts. The vacuum pump 401 is connected to the collection bottle 309 by the connecting pipe 402, so that the vacuum pump 401 works with the connecting pipe 402 to perform vacuum suction inside the collection bottle 309. The connecting hose 405 connected to the upper end of the collection bottle 309 generates negative pressure to attract external substances, and the check valve 406 prevents the liquid from flowing back. At the same time, the liquid level sensor 403 monitors the liquid level inside the collection bottle 309, and the buzzer 404 reminds the staff to replace the collection bottle 309 when the liquid level reaches the preset value, which further improves the overall practicality and efficiency of the negative pressure suction device.

[0023] In summary, when using this rescue negative pressure suction device, first screw the mounting cap 2 onto the upper part of the main housing 1. The spring damping rod 304 elastically connects the limiting ball 305 to the receiving groove 303. Simultaneously, the docking groove 302, in conjunction with the docking block 306, completes the docking and limiting of the fixing block 308 and the mounting block 301. The limiting through groove 307, in conjunction with the limiting ball 305, fixes the docking block 306 inside the mounting block 301, thereby fixing the collection bottle 309 in place and improving the overall ease of assembly and disassembly of the collection bottle 309. The vacuum pump 401, in conjunction with the connecting pipe 402, performs a vacuum suction operation inside the collection bottle 309. The connecting hose 405 connected to the upper end of the collection bottle 309 then generates negative pressure to attract external substances. In conjunction with the check valve 406, the backflow of liquid is prevented. At the same time, the liquid level sensor 403 monitors the liquid level inside the collection bottle 309, and when the liquid level reaches the preset value, the buzzer 404 reminds the staff to replace the collection bottle 309, further improving the overall practicality and efficiency of the negative pressure suction device.
