Description

Technical Field

[0001] The present invention mainly relates to the technical field of medical equipment, and in particular to an easy-to-clean assembled negative pressure aspirator. Background Art

[0002] The negative pressure suction device is composed of a pressure regulator, a liquid collecting bottle, a hose, etc. There are two hose interfaces on the liquid collecting bottle, one connected to the negative pressure terminal, and the other connected to the working chamber; when the negative pressure terminal is connected, air negative pressure will be generated in the liquid collecting bottle, and the negative pressure will guide dirt (such as dirty blood, sputum, etc.) to flow into the liquid collecting bottle from the other hose; when the liquid level in the liquid collecting bottle reaches a certain height, the stop valve on the liquid collecting bottle cover will start to work, cutting off the liquid flowing into the pipeline, thereby preventing the liquid in the liquid collecting bottle from overflowing due to excess; considering the different drainage volumes, multiple liquid collecting bottles can be cascaded to achieve the extraction and storage of large amounts of liquid; the negative pressure suction device has two structures: split and integrated. The split structure separates the pressure regulator from the liquid collecting bottle, connects them through a hose, and the gas terminal plug is connected to the pressure regulator together.

[0003] During the specific implementation process, the inventor discovered the following defects: The split-type negative pressure aspirators currently on the market will inevitably leave some waste liquid or bacterial particles in the hose after use, which is troublesome to clean and easily leads to incomplete cleaning. The general solution is to directly replace the hose, which increases the consumption of consumables and leads to increased costs.

[0024] Refer to the attached Figure 1-7 , an easy-to-clean assembled negative pressure aspirator, comprising a negative pressure regulator body 1 and a base 2, a self-cleaning mechanism 3 and a positioning mechanism 4 are arranged in sequence at the front end of the negative pressure regulator body 1, a collecting container 5 is arranged on the positioning mechanism 4, a positioning plate 6 is arranged at the front end of the self-cleaning mechanism 3 near the positioning mechanism 4, a lifting card assembly 7 is arranged on the positioning plate 6, wherein the positioning mechanism 4 comprises a card seat 401 and a rotating motor 402, a telescopic card holder 403 connected to the driving end of the rotating motor 402 is arranged in the card seat 401, the collecting container 5 comprises a bottle cap 501 and a bottle body 502, a filter inner cover 503 is arranged in the bottle body 502.

[0025] Refer to the attached Figure 1-7The self-cleaning mechanism 3 includes a shell 305, a water tank 301, a cleaning connecting pipe 1 302, a high-pressure spray nozzle 303 and a cleaning connecting pipe 2 304. The two ends of the cleaning connecting pipe 1 302 are respectively connected to the water tank 301 and the high-pressure spray nozzle 303. The water tank 301 is arranged in the shell 305. The water tank 301 is provided with an electric control valve 306. The cleaning connecting pipe 1 302 penetrates the shell 305 and is connected to the electric control valve 306. The self-cleaning mechanism 3 is connected to the negative pressure pump connecting pipe 101 on the negative pressure regulator body 1 through the cleaning connecting pipe 2 304. The atomized water vapor sprayed by the high-pressure spray nozzle 303 is used to rinse a section where the negative pressure pump connecting pipe 101 is connected to the bottle cap 501 to keep the inside of the negative pressure pump connecting pipe 101 clean to prevent cross contamination during the next use. The water tank 301 controls the spray flow rate through the electric control valve 306. The electric control valve 306 is connected to the switch button to realize controllable cleaning.

[0026] Refer to the attached Figure 1-7 A negative pressure pump connecting pipe 101 is connected to the negative pressure regulator body 1, and a filter 102 is arranged on the negative pressure pump connecting pipe 101. One end of the negative pressure pump connecting pipe 101 is connected to the bottle cap 501, and one end of the cleaning connecting pipe 304 is connected to the negative pressure pump connecting pipe 101. The filter 102 arranged on the negative pressure pump connecting pipe 101 can prevent the negative pressure pump connecting pipe 101 from flowing into the negative pressure regulator body 1, prevent bacterial particles and waste liquid from entering the pipeline system of the negative pressure regulator body 1, reduce the maintenance rate of the pipeline system, and reduce the risk of cross infection.

[0027] Refer to the attached Figure 1-7 The bottle body 502 is placed in the holder 401, and the bottom of the bottle body 502 has a recessed portion that is mutually engaged with the telescopic holder 403. The bottle body 502 is threadedly connected to the bottle cap 501. The bottle cap 501 is provided with a drainage connection pipe 504 that is connected thereto. The rear end of the bottle cap 501 is fixedly connected to the lifting card assembly 7. A sealing ring is provided between the filter inner cover 503 and the bottle body 502. The filter inner cover 503 is also provided with a pick-up and drop portion 5031. The filter inner cover 503 can be pulled out of the bottle body 502 by grabbing the pick-up and drop portion 5031, and can be placed in the bottle body 502. When separated from the bottle cap 501, the filtering inner cover 503 plays the role of sealing the bottle body 502 to prevent the waste liquid or bacterial particles in the collection container 5 from overflowing or leaking during the taking and placing process. The bottle body 502 and the bottle cap 501 are connected in a split manner, wherein the bottle cap 501 is fixed by a lifting card plate assembly 7, and the lower end of the bottle body 502 is inserted into the holder 401 of the positioning mechanism 4, and is clamped with the telescopic card holder 403. The telescopic card holder 403 is rotated by the rotating motor 402 to drive the bottle body 502 to rotate, thereby realizing the screwing action between the bottle body 502 and the bottle cap 501.

[0028] Refer to the attached Figure 1-7The lifting card assembly 7 includes an automatic telescopic locking mechanism 701 and a connecting plate 702 connected thereto. A curved plate 703 and a positioning block 704 are provided on one side of the connecting plate 702 close to the bottle cap 501. The curved plate 703 is in contact with the side of the bottle cap 501, and the positioning block 704 is fixedly connected to the upper end surface of the bottle cap 501. In the present technical solution, the automatic telescopic locking mechanism 701 is a prior art and will not be described in detail herein. By pressing the automatic telescopic locking mechanism 701, the up and down position adjustment of the curved plate 703 and the positioning block 704 is achieved, thereby driving the bottle cap 501 to move up and down to cooperate with the taking and placing operation of the bottle body 502.

[0029] Refer to the attached Figure 1-6 The positioning mechanism 4 is located at the front end of the positioning plate 6. The positioning mechanism 4 is detachably connected to the negative pressure regulator body 1 and the base 2. In the present technical solution, the tray 403 has a double-layer positioning plate, and a spring structure is arranged between the two positioning plates. During the screwing process of the bottle body 402 and the bottle cap 401, the bottle body 402 can achieve a small upward and downward floating space; during cleaning, the positioning mechanism 4 can be separated from the negative pressure regulator body 1 as a whole to prevent the atomized water vapor sprayed by the high-pressure spray nozzle 303 from wetting the positioning mechanism 4.

[0030] In this embodiment, the negative pressure pump connecting pipe 101, the drainage connecting pipe 504, the cleaning connecting pipe 1 302, and the cleaning connecting pipe 2 304 are all soft tubes, and the collecting container 5 is made of glass; The specific implementation is as follows: Installation: put the clean bottle body 502 into the positioning mechanism 4, install the filter inner cover 503, insert the bottle bottom into the holder 401 and clamp it on the holder 403, and adjust the bottle cap 401 to the lower gear by pressing the automatic telescopic locking mechanism 701 in the lifting card assembly 7, so as to facilitate docking with the bottle body 502, start the rotating motor 402 to rotate forward, and the holder 403 connected to the driving end of the rotating motor 402 drives the bottle body 502 to rotate. As the bottle body 502 rotates, it is gradually screwed upward and connected to the bottle cap 401 through a thread. After the bottle body 502 and the bottle cap 501 are screwed into place, the rotating motor 402 stops; the drainage connecting pipe 504 on the bottle cap 501 is connected to the working chamber, and the negative pressure pump connecting pipe 101 is connected to the negative pressure regulator body 1; Start: Start the negative pressure regulator body 1, set the drainage volume, start to guide the waste into the collection container 5, and close the negative pressure regulator body 1 after completion; Taking out: Start the rotary motor 402 to rotate in the reverse direction, the bottle body 502 and the bottle cap 501 are separated by reverse rotation, the automatic telescopic locking mechanism 701 is pressed again, the bottle cap 401 is adjusted to the upper gear position, and the bottle body 502 with the filter inner cover 503 is taken out; Cleaning: remove the positioning mechanism 4 as a whole, then start the self-cleaning mechanism 3, open the electric control valve 306, and clean water from the water tank 301 passes through the cleaning connecting pipe 302 and is sprayed out from the high-pressure spray nozzle 303 after being atomized. The sprayed atomized water vapor enters the front section of the negative pressure pump connecting pipe 101 to perform high-pressure washing on the inside.

[0031] To sum up, the present technical solution adopts a separate and automatically dockable collection container 5 to reduce the frequency of operator contact with the collection container 5, and realizes automatic cleaning of the negative pressure pump connecting pipe 101 by providing a self-cleaning mechanism 3 connected to the negative pressure pump connecting pipe 101, thereby avoiding contamination of the internal piping system of the negative pressure regulator body 1 and avoiding cross contamination during the next use, thereby effectively improving the convenience during use.

[0032] The above-described embodiments only express a certain implementation mode of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
