Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a portable handheld sputum suction device. Background Art

[0002] In daily medical care, respiratory infections and other conditions may cause a significant increase in respiratory secretions, and patients are prone to symptoms such as coughing and sputum. Some patients cannot cough up sputum on their own, and need to use a special suction device to suck out the sputum. Commonly used suction devices are wall-mounted devices or plug-in electric devices, which have the following technical defects when used: they require a fixed position and cannot move with the patient over a large range; when transporting patients in the hospital, especially for short-distance treatment such as intra-hospital transfer and home treatment, sputum is basically temporarily suctioned through a large empty syringe and a suction tube, which is extremely inconvenient to use; it is impossible to check whether the pressure in the patient's airway is appropriate, whether the front end of the suction tube is on the airway wall, and incorrect forceful suction may cause airway damage and bleeding, thereby inducing the possibility of suffocation; manual suction suction devices are rare on the market. This manual suction suction device is a negative pressure cupping device plus a disposable sputum collection bag, equipped with a small number of suction tubes; the suction nursing operation requires professional operation, and the suction tube is made of soft and easy-to-bend material. Ordinary people cannot accurately insert the suction tube into the patient's airway, and the patient will subconsciously bite the suction tube, and the operator cannot suck out the sputum, resulting in delays in the condition; the manual suction suction device requires the cooperation of both hands and cannot be operated with one hand. Once the disposable sputum collection bag is full, it can no longer be used; the sputum sucked out by the existing sputum collection bag may flow back into the suction device due to gravity.

[0003] Therefore, how to design a portable handheld sputum suction device has become an urgent problem to be solved. Summary of the invention

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

[0005] The technical solution of the present invention is: a portable handheld sputum suction device, comprising a main body, which is connected to a split body, a negative pressure suction device and a lithium battery are arranged in the main body, and a driving part of the negative pressure suction device is connected to the lithium battery; a Y-shaped sputum suction tube is arranged in the split body, the Y-shaped sputum suction tube 5 is a replaceable sputum suction tube, a first opening of the Y-shaped sputum suction tube is communicated with the suction port of the negative pressure suction device, a second opening of the Y-shaped sputum suction tube is exposed to the side wall of the split body, the second opening of the Y-shaped sputum suction tube is connected to a transparent replaceable sputum collection bag, a third opening of the Y-shaped sputum suction tube is exposed from the bottom surface of the split body, and the third opening of the Y-shaped sputum suction tube can enter the patient's oral cavity.

[0006] The present invention adopts a dual separation mode of a main device that can be detached and charged and a split device that needs to be disinfected. The negative pressure suction device is driven by a motor to generate negative pressure to absorb sputum. The machine has a longer service life, a small size, and is easy to carry. It can be used as an emergency rescue instrument for patients who need to be transferred or move over a large area outside the ward for examination. When the patient suffocates due to sputum, the sputum can be sucked out immediately to save the patient's life. The operation can be performed by medical staff or the patient's family members. At the same time, a replaceable Y-shaped sputum suction tube is used. When the patient's sputum is thick and blocks the catheter, the pipeline can be replaced immediately, which is convenient for replacement and disinfection. One person can use one, which meets the requirements for the use of medical equipment, prevents cross infection, and saves medical resources. BRIEF DESCRIPTION OF THE DRAWINGS
