Description

Technical Field

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

[0002] In the medical field, a negative pressure suction device for the throat is a common device, mainly used to remove secretions and foreign objects from the throat. It works by creating a pressure environment below atmospheric pressure, using the pressure difference to suction out liquids or solids from the throat, thereby achieving cleaning and treatment purposes.

[0003] In related technologies, negative pressure is created by pulling on a corrugated tube. However, due to the structural characteristics of the corrugated tube, its mechanical strength is insufficient, making it difficult for the patient to apply enough pulling force during voluntary operation. This results in unstable negative pressure generation, a technical defect that may affect the effectiveness of emergency treatment and pose operational safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a negative pressure suction device for the throat, addressing the problem in related technologies where patients using corrugated tubes cannot apply sufficient suction force during voluntary operation, leading to unstable negative pressure generation. This technical defect may affect the effectiveness of emergency treatment and pose operational safety hazards. Therefore, this invention provides a negative pressure suction device for the throat, comprising: a main body, a pull rod, a piston, and a mask. The pull rod extends from one end of the main body into the interior of the main body. The piston is fixedly installed at one end of the pull rod and is located inside the main body, slidably connected to it. The mask is fitted and connected to the main body.

[0005] Preferably, a connecting seat is provided on the side wall of the main body, and the connecting seat is connected to the mask.

[0006] Preferably, the center of the connecting seat is provided with a first air hole.

[0007] Preferably, a first one-way valve is provided inside the main body.

[0008] Preferably, the pull rod is connected to the piston via a thread.

[0009] Preferably, the piston is provided with a sealing ring.

[0010] Preferably, the bottom of the main body is provided with a bottom cover.

[0011] Preferably, the bottom cover is provided with a second air hole.

[0012] Preferably, a second one-way valve is provided at the second air hole.

[0013] Preferably, a handle is fixedly installed at one end of the pull rod.

[0014] Beneficial effects:

[0015] 1. This utility model provides a negative pressure suction device for the throat, which forms negative pressure through the structure of the pull rod and piston. The structure is stable, the suction is strong, and it is simple and convenient to use, allowing patients to operate it themselves. Attached Figure Description

[0023] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0024] Example 1:

[0025] Provided such as Figure 1-5The pharyngeal negative pressure suction device shown includes: a main body 1, a pull rod 2, a piston 3 and a mask 4. The pull rod 2 extends from one end of the main body 1 into the interior of the main body 1. The piston 3 is fixedly installed at one end of the pull rod 2 and is inside the main body 1. The piston 3 is slidably connected to the main body 1. The mask 4 is connected to the main body 1 in a cooperative manner.

[0026] A connecting seat 11 is provided on the side wall of the main body 1, and the connecting seat 11 is connected to the face mask 4. A first air hole 12 is provided in the center of the connecting seat 11. A first one-way valve 13 is provided inside the main body 1. The face mask 4 is set on the side wall of the main body 1 through the connecting seat 11, and works with the first one-way valve 13 to prevent foreign objects from entering the interior of the main body and causing contamination when foreign objects are removed. The face mask 4 is available in various sizes to suit different groups of people. For example, the size of the adult face mask is 102×132mm, and the size of the child face mask is 77×100mm. The size of the face mask 4 can be customized according to actual needs, as long as the interference fit between the face mask 4 and the connecting seat 11 ensures a stable connection.

[0027] The lever 2 and piston 3 are connected by threads. The piston 3 has a groove for placing the sealing ring 5 to achieve a seal between the piston and the main body. A handle 6 is fixedly installed at one end of the lever 2 for easy pulling. The lever 2 drives the piston 3 to slide within the main body 1, generating negative pressure to form suction from the mask 4, thereby sucking out foreign objects from the patient's throat.

[0028] A bottom cover 7 is provided at the bottom of the main body 1, and the bottom cover 7 is fixedly connected to the main body 1. A second vent 71 is provided on the bottom cover 7. A second one-way valve 72 is provided at the second vent 71.

[0029] Working principle: The mask 4 is fastened over the patient's mouth and nose. Pulling handle 6 causes lever 2 to move piston 3 within the main body 1 away from the mask 4, creating negative pressure and suction from the mask 4, thus drawing out foreign objects from the patient's throat. Pressing handle 6 pushes lever 2 to move piston 3 closer to the mask 4, expelling air from the second one-way valve 72 on the bottom cover 7. Repeating the pulling and pressing of handle 6 continues until all foreign objects in the patient's throat are completely drawn out.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
