[0001] The present invention relates to the technical field of sputum aspirators, and particularly to a visual sputum aspirator. Background Art

[0002] Sputum aspirators mainly include electric multi-functional negative pressure sputum aspirators and simple manual sputum aspirators. The operating end needs to be connected to a sputum suction tube or a sponge sputum suction tube before use. Generally, the electric type is commonly used, which has a power switch and a manual control switch, and uses the negative pressure principle for sputum aspiration and oral care, which is simple and easy to learn. It is used for routine sputum aspiration, tracheotomy and other treatments of the wounded and sick, and is suitable for military combat rescue medical treatment as well as timely sputum aspiration treatment in hospitals or at home when there is respiratory mucus or vomiting.

[0003] In the existing sputum aspiration device, during the use process, the medical staff places the sputum suction tube into the patient's esophagus for sputum aspiration operation. Since the above method is a blind aspiration, it is easy to cause mucosal damage, and the efficiency is low. The risk is higher especially in critically ill patients or children, resulting in lower performance. Therefore, a visual sputum aspiration device is urgently needed to solve the existing problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a visual sputum aspiration device to solve the above problems.

[0005] The present invention achieves the above purpose through the following technical solutions:

[0006] A visual sputum aspiration device includes an operation handle. A sleeve is arranged inside the operation handle. A partition is arranged inside the sleeve. A sputum suction tube is also inserted into the sleeve. A camera is arranged inside the free end of the sleeve. A supplementary light is installed outside the camera. A silica gel transparent cover is arranged on one side of the camera. A display screen is installed on one side wall of the operation handle. A transmission optical fiber is connected between the display screen and the camera. A pressure sensor is arranged on the outer side wall of the end of the sputum suction tube close to the sputum suction port. The pressure sensor is internally provided with a Bluetooth module. A pressure regulating valve is arranged at the end of the sputum suction tube far from the sputum suction port.

[0007] Further, the partition is formed inside the sleeve, and the sputum suction tube is bonded inside the sleeve.

One group of channels is used to install the sputum suction tube, and the other group of channels is used to install the adjusting wire and the camera, which can ensure that both groups of mechanisms are in normal use.

[0009] Further, the position of the sleeve port is 1 - 3 mm. The supplementary light is an LED light source, and the material of the silica gel transparent cover is medical silica gel.

[0010] By adopting the above technical solution, during the sputum suction process, the camera can capture the picture of sputum suction, the supplementary light lamp provides supplementary light for it, and transmits the captured picture into the display screen, thereby playing a role of visual auxiliary observation for medical staff and realizing the integrated operation of "suction while observing".

[0011] Furthermore, the display screen is fixed on the operating handle by screws. The transmission optical fiber is electrically connected to both the display screen and the camera, and the transmission optical fiber is laid along the inner wall of the sleeve.

[0012] By adopting the above technical solution, the transmission optical fiber can transmit the captured picture to the display screen at high speed for display.

[0013] Furthermore, the detection surface of the pressure sensor is a flexible sheet. The pressure sensor is remotely connected to the display screen through a Bluetooth module, and the pressure regulating valve is installed on the sputum suction tube by means of threads.

[0014] By adopting the above technical solution, during the flow of sputum in the sputum suction tube, the pressure sensor can detect the viscosity of the sputum and transmit the detected data into the display screen. The staff controls the pressure regulating valve by observing the detected data, thereby adjusting the negative pressure degree and realizing the automatic adjustment of the negative pressure intensity.

[0015] Furthermore, operation buttons are reserved on the operating handle, and the operation buttons are electrically connected to both the pressure regulating valve and the display screen.

At the same time, the camera can capture the sputum suction picture, the fill light supplements light for it, and the transmission optical fiber transmits the captured picture into the display screen, so as to play a visual auxiliary observation role for medical staff and realize the integrated operation of "suction while observing". When the sputum flows in the sputum suction tube, the pressure sensor can detect the viscosity of the sputum and transmit the detection data into the display screen. The staff observes the detection data and controls the pressure regulating valve through the operation button to adjust the negative pressure degree, so as to realize the automatic adjustment of the negative pressure intensity. And by rotating the adjusting knob, it drives the winding disc to rotate through the connecting shaft, so as to wind the adjusting steel wire.
