Description

visual aspirator

technical field

The utility model relates to a clinical medical device, in particular to a visual sputum suction device with convenient use and enhanced safety.

Background technique

Clinically, many patients cannot expectorate sputum on their own, and need artificial assisted sputum suction to keep the airway unobstructed and facilitate lung ventilation. Therefore sucking sputum with sputum aspirator is a kind of medical technology commonly used in clinical medicine, but there are many defects in existing sputum aspirator: for example conventional sputum aspirator mainly by operator's feeling and experience, blind intubation carries out sputum suction. This deep intubation method will directly cause damage to the tracheal mucosa, including congestion and edema, epithelial peeling, loss of cilia, and granuloma formation, and increases the chance of bleeding and infection in patients. It is also often caused by irritating cough or insufficient oxygen supply. The patient has hypoxemia; if the suction tube is inserted too shallow, the sputum in the upper part of the airway can only be sucked out, but not all the sputum can be completely sucked out, and the sputum in the deep part of the trachea can easily form sputum scabs to block the airway or lead to pulmonary infection complication.

At present, sputum suction can also be performed under the guidance of laryngoscope or bronchofiberscope, but the former can only observe part of the airway, which is not helpful for deep sputum suction, while the latter needs to be performed on the basis of local anesthesia, which is cumbersome to operate. The cost of the two is expensive, and the technical level of medical personnel is high. Therefore, there is an urgent need for a more convenient and effective suction method and technology to serve clinical work.

Contents of the invention

The purpose of this utility model is to overcome the above-mentioned shortcomings existing in the prior art, and provide a visual sputum suction device that is convenient to use, simple to operate, more effective and enhances safety.

The utility model is realized through the following technical solutions. A visible sputum suction device includes a transparent tube body made of medical polymer materials, and a sputum suction channel is axially arranged in the tube body; the feature is that: An observation cavity is arranged in the tube body, and a micro camera or an optical fiber is placed in the observation cavity, and the signal line of the micro camera or the other end of the optical fiber is led out of the tube body and connected to the signal output end of the visual device.

The utility model has the advantages of adopting the above-mentioned structure: due to the visibility, the blindness in the process of suctioning the sputum is greatly reduced, and the location of the accumulated sputum can be quickly and accurately found and eliminated in time, greatly reduce the suffering of patients. And the operation is simple and has no technical requirements.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Referring to the accompanying drawings, it includes a transparent tube body 1 made of medical polymer material, and a sputum suction channel is arranged axially in the tube body; A micro-camera or an optical fiber is placed in the observation cavity, and the signal line of the micro-camera or the other end of the optical fiber is led out of the tube and connected to the signal output end of the visual device 6 .

The miniature camera and its visual device adopt commercially available products, such as DX-8623, an ultra-small high-definition camera of Dingxin Company, to be remanufactured.

The optical fiber and its visual device are commercially available products, such as Shanghai Precision Fiber Bronchoscope XZ3 refitted.

In the embodiment shown in the drawings, an oxygen injection channel 8 is also provided in the pipe body 1 .

As shown in the figure: the front end of the tube body 1 is blunt; the side wall of the inlet end of the sputum suction channel 7 is provided with a through hole 3 . A through hole 3 is opened on the side wall of the outlet of the oxygen injection channel 8 .

The working principle of the utility model: insert the front end of the sputum suction tube 1 into the throat from the patient's mouth or nostril, connect the tail end of the sputum suction channel with the sputum suction machine; look for the position of the accumulated sputum under the guidance of the visual device 6 , and then turn on the suction machine to achieve visual suction.

With the above structure, an oxygen injection machine can also be connected to the tail end of the oxygen injection channel 8 to ensure smooth breathing of the patient. This not only reduces the patient's pain, reduces the patient's medical expenses and improves the work efficiency of the nursing staff, because the micro-camera or optical fiber is in the observation cavity, there is no pollution during use, and it can be used multiple times, saving costs.
