Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a portable handheld suction device. Background Technology

[0002] In routine medical practice, respiratory infections and other conditions can lead to a significant increase in respiratory secretions, causing symptoms such as coughing and phlegm production. Some patients may experience difficulty coughing up phlegm on their own, requiring the use of specialized suction devices. Commonly used suction devices are either wall-mounted or plug-in electric devices, which have the following technical drawbacks: they require a fixed location, making it impossible to move the device around with the patient; during patient transport within the hospital, especially for short-distance procedures like intra-hospital transport or home visits, phlegm is typically suctioned temporarily using a large-bore syringe and suction tube, which is extremely inconvenient; it's impossible to check if the airway pressure is appropriate or if the suction tube is properly positioned against the airway wall, potentially leading to airway damage and bleeding, and even suffocation; manual suction devices are rare on the market. This manual suction device consists of a negative pressure cupping device with a disposable sputum collection bag and a small number of suction tubes. The suctioning procedure requires professional skills, and the suction tubes are made of a flexible and easily bendable material, making it difficult for ordinary people to accurately insert the tubes into the patient's airway. Furthermore, patients may subconsciously bite down on the suction tubes, preventing the operator from suctioning sputum and thus delaying treatment. The manual suction device requires both hands and cannot be operated with one hand. Once the disposable sputum collection bag is full, it cannot be used again. Due to gravity, the sputum suctioned from the existing sputum collection bag may flow back into the suction device.

[0003] Therefore, designing a portable handheld suction device has become an urgent problem to be solved. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides a portable handheld suction device to solve at least one of the above-mentioned technical problems.

[0005] The technical solution of this utility model is: a portable handheld suction device, including a main body and a split body. The main body is equipped with a negative pressure suction device and a lithium battery. The driving part of the negative pressure suction device is connected to the lithium battery. The split body is equipped with a Y-shaped suction tube. The Y-shaped suction tube 5 is a replaceable suction tube. The first opening of the Y-shaped suction tube is connected to the suction port of the negative pressure suction device. The second opening of the Y-shaped suction tube is exposed on the side wall of the split body and is connected to a transparent replaceable sputum collection bag. The third opening of the Y-shaped suction tube is exposed from the bottom surface of the split body and can enter the patient's oral cavity.

[0006] This invention employs a dual-separation mode, consisting of a detachable, separately charged main unit and a separate unit requiring disinfection. The negative pressure suction device generates negative pressure via a motor to suction sputum, resulting in a longer service life. Its smaller size and portability make it easy to carry. For patients requiring extensive transport or leaving the ward for examination, it can be used as an emergency medical device. In cases of sputum choking, sputum can be suctioned immediately to save the patient's life. It can be operated by medical staff or family members. Furthermore, the use of a replaceable Y-shaped suction catheter allows for immediate replacement when the patient's sputum becomes viscous and clogs the catheter, facilitating disinfection and ensuring one-person-one-use, meeting medical device usage requirements, preventing cross-infection, and conserving medical resources.
