Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, in particular to a medical aspirator. Background Art

[0002] A medical aspirator is a medical device mainly used to remove secretions, blood, pus and other liquid substances from the patient's body. It is usually composed of a negative pressure source, a collection container, connecting pipes and a control device. By generating negative pressure, the liquid is sucked out of the patient's body to keep the surgical area or the patient's respiratory tract clean, which helps the smooth progress of medical operations and the patient's recovery.

[0003] A portable suction pump is a small suction device that is easy to carry and operate. It is mainly used to suck out sputum in the patient's respiratory tract in time in emergency situations or when it needs to be used on the move to keep the respiratory tract unobstructed. Compared with traditional large-scale suction equipment, the portable suction pump has the characteristics of small size, simple operation and easy use. The working principle of the electric portable suction pump is that the electric pump or compressor starts to run, and the air inside the suction pump is extracted, so that a pressure difference is formed between the inside of the suction pump and the outside world, generating negative pressure. Under the action of negative pressure, the suction tube connected to the suction pump will suck the sputum in the patient's respiratory tract into a special collection container to achieve the purpose of clearing the respiratory tract.

[0004] In existing portable sputum aspirators, the connecting tube on the top of the cover is usually connected to a disposable medical connecting pipe, wherein the two sets of pipes are connected to the aspirator and the patient respectively, so as to suck the sputum in the patient's respiratory tract into the cover. However, when the device is not in operation, the top of the connecting pipe is open, which makes it easy for dust to enter the collection box. In addition, the pipe is sleeved on the outer wall of the connecting pipe, and there is no good positioning of the pipe. Long-term use can easily cause the pipe to shift. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a medical suction device to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a medical suction device, comprising a device shell and a collection box, a cover plate is provided on the top of the collection box, and multiple groups of connecting tubes are installed on the top of the cover plate, a dust block is provided on the top of the connecting tube, and a positioning assembly for limiting the pipeline is provided at one end of the connecting tube, the positioning assembly comprises a slider, a positioning block and a rotating rod, a positioning block is provided at one end of the slider, and a rotating rod is provided on the inner wall of the positioning block, a belt is provided on one end of the rotating rod, and a screw is provided on the other end of the belt, and a nut is movably installed on the outer wall of the screw.

[0007] By adopting the above technical solution, the top of the connecting pipe is effectively sealed by setting up multiple groups of dust-proof blocks, and the round blocks formed by the multiple groups of dust-proof blocks fit the diameter of the top of the connecting pipe, and a torsion spring is set between the bottom of the multiple groups of dust-proof blocks and the connecting pipe. When the pipe is pulled out from the surface of the connecting pipe, the multiple groups of dust-proof blocks will automatically close, effectively sealing the top of the connecting pipe and reducing the entry of dust into the collection box. Through the setting of the positioning component, when the medical staff inserts the pipe into the outer wall of the connecting pipe, the bottom of the pipe contacts the nut, and the nut drives the screw to rotate, so that the sliders at both ends of the connecting pipe clamp the pipe, and effectively limit the position of the pipe, thereby improving the stability and sealing of the connection between the pipe and the connecting pipe.

[0008] Furthermore, the number of the dust-proof blocks is eight groups, and the eight groups of dust-proof blocks form a circular plate shape, and the connecting pipe and the multiple groups of dust-proof blocks are connected by a torsion spring.

[0009] By adopting the above technical solution, multiple groups of dust blocks are located in the pipeline, and the multiple groups of dust blocks are in an upward-turned shape. The outer walls of the dust blocks fit the inner walls of the pipeline. When the pipeline is pulled out, the multiple groups of dust blocks will automatically close, effectively sealing the top of the connecting pipe and reducing dust from entering the collection box.

[0010] Furthermore, a magnetic block is provided at one end of the sliding block close to the connecting pipe, and the magnetic block is in contact with the outer wall of the connecting pipe.

[0011] By adopting the above technical solution, the position of the slider is effectively limited, and the outer wall of the pipe is limited, which reduces the displacement of the slider, improves the sealing of the connection between the pipe and the connecting pipe, and thus improves the quality of the equipment.

[0012] Furthermore, a metal sheet is provided on the inner wall of the connecting pipe, and the metal sheet is arranged opposite to the magnetic block.

[0013] By adopting the above technical solution, the metal sheet and the magnetic block are arranged relative to each other, so that the magnetic block and the metal sheet are adsorbed, which effectively limits the position of the pipeline and improves the sealing of the pipeline sleeve on the outer wall of the connecting pipe.

[0014] Furthermore, support rods are sleeved on both ends of the slider, and a first spring is provided on the outer wall of the support rod, and the first spring is located between the two groups of sliders.

[0015] By adopting the above technical solution, the slider is driven to move toward both ends by the action force of the first spring, which facilitates the reset of the slider.

[0016] Furthermore, the positioning block is in a rectangular shape, and the rotating rod on the inner wall of the positioning block is movably connected to the inner wall of the cover plate.

[0017] By adopting the above technical solution, the positioning block is driven to rotate by the rotating rod so that the two groups of sliders move, and the positioning block limits the position of the sliders.

[0018] Furthermore, the screw and nut are ball screw nuts, and the outer wall of the screw is sleeved with a second spring, and the bottom of the screw is also movably connected to the inner wall of the cover.

[0019] By adopting the above technical solution, when the medical staff pulls the pipe upward, the nut moves upward under the action of the second spring, driving the screw to flip, thereby causing the slider to detach from the outer wall of the connecting pipe, thereby releasing the limit on the pipe.

[0020] Furthermore, one end of the nut close to the connecting pipe is in an arc shape, and the arc-shaped end of the nut is in contact with the outer wall of the connecting pipe.

[0021] By adopting the above technical solution, the bottom of the pipe contacts the nut, which drives the nut downward. The downward movement of the nut causes the screw to rotate, which drives the belt to rotate, causing the rotating rod to drive the positioning block to rotate.

[0022] Furthermore, a sliding groove is provided on the top of the cover plate, and the sliding groove is engaged with the bottom of the sliding block.

[0023] By adopting the above technical solution, the movement trajectory of the slider is controlled by setting the sliding groove and the stability of the slider during movement is effectively improved.

[0024] In summary, the present invention mainly has the following beneficial effects:

[0025] 1. The present invention effectively seals the top of the connecting pipe by setting up multiple groups of dust-proof blocks, and the round blocks formed by the multiple groups of dust-proof blocks fit the diameter of the top of the connecting pipe, and a torsion spring is provided between the bottom of the multiple groups of dust-proof blocks and the connecting pipe. When the pipe is pulled out from the surface of the connecting pipe, the multiple groups of dust-proof blocks will automatically close, effectively sealing the top of the connecting pipe and reducing dust from entering the collection box.

[0026] 2. The present invention provides a positioning component. When medical personnel insert the pipe into the outer wall of the connecting pipe, the bottom of the pipe contacts the nut. The nut drives the screw to rotate, so that the sliders at both ends of the connecting pipe clamp the pipe and effectively limit the position of the pipe, thereby improving the stability and sealing of the connection between the pipe and the connecting pipe.

A positioning block 34 is provided at one end of the slider 30, and a rotating rod 35 is provided on the inner wall of the positioning block 34. A belt 36 is provided at one end of the rotating rod 35, and a screw 5 is provided at the other end of the belt 36. A nut 50 is movably installed on the outer wall of the screw 5. By setting multiple groups of dust blocks 4, the top of the connecting pipe 21 is effectively sealed, and multiple The round block formed by the group of dust-proof blocks 4 fits the diameter of the top of the connecting tube 21, and a torsion spring is arranged between the bottom of the multiple groups of dust-proof blocks 4 and the connecting tube 21. When the pipe is pulled out from the surface of the connecting tube 21, the multiple groups of dust-proof blocks 4 will automatically close, effectively sealing the top of the connecting tube 21, reducing the entry of dust into the collection box 2. Through the setting of the positioning component 3, when the medical staff inserts the pipe into the outer wall of the connecting tube 21, the bottom of the pipe contacts the nut 50, and the screw 5 is driven to rotate by the nut 50, so that the sliders 30 at both ends of the connecting tube 21 clamp the pipe and effectively limit the position of the pipe, thereby improving the stability and sealing of the pipe when connected to the connecting tube 21.

[0037] See also Figure 1 - Figure 4 The number of dust-proof blocks 4 is eight groups, and the eight groups of dust-proof blocks 4 form a circular plate shape. The connecting pipe 21 is connected to the multiple groups of dust-proof blocks 4 by a torsion spring. Through the downward pushing force of the medical staff, the multiple groups of dust-proof blocks 4 are located in the pipeline, and the multiple groups of dust-proof blocks 4 are turned upside down. The outer wall of the dust-proof block 4 fits with the inner wall of the pipeline. When the pipeline is pulled out, the multiple groups of dust-proof blocks 4 will automatically close, effectively sealing the top of the connecting pipe 21, reducing dust from entering the collection box 2.

[0038] See also Figure 4 - Figure 6 A magnetic block 31 is provided at one end of the slider 30 close to the connecting pipe 21, and the magnetic block 31 is in contact with the outer wall of the connecting pipe 21. A metal sheet is provided on the inner wall of the connecting pipe 21, and the metal sheet and the magnetic block 31 are arranged opposite to each other, so that the magnetic block 31 and the metal sheet are adsorbed, which effectively limits the position of the pipeline and improves the sealing of the pipeline on the outer wall of the connecting pipe 21.
