Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a rapid liquid extraction device. Background Art
[0002] Traditionally, when preparing vasoactive drugs or configuring analgesic pumps, physiological saline or other liquids need to be extracted to dilute the drug solution. The usual clinical method of extracting saline or other liquids is to draw the required amount of liquid from a large-capacity bag or liquid container or other liquid with a syringe with a needle, and then inject it into the drug solution that needs to be diluted.
[0003] However, the existing extraction method is time-consuming, labor-intensive, and has a cumbersome configuration process, which brings great inconvenience to medical staff. In addition, the operation of extracting saline or other liquids multiple times also increases the risk of contamination of saline and liquid medicine. For this reason, we propose a rapid extraction device. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rapid liquid extraction device, comprising a liquid container, and a liquid extraction mechanism and an anti-reversal mechanism located below the liquid container;
[0006] The surface of the liquid container is provided with a scale mark, the bottom of the liquid container is provided with a puncture tube, the surface of the puncture tube is provided with a first liquid passage opening, and a limit block is provided below the puncture tube.
[0007] Preferably, the liquid pumping mechanism includes a hemispherical plug, a baffle is connected below the hemispherical plug, a second liquid port is provided below the baffle, a liquid pump is provided below the second liquid port, and a piston is provided below the liquid pump.
[0008] Preferably, a pressure rod is connected below the piston, and a return spring is arranged outside the pressure rod.

[0012] Preferably, a first liquid extraction pipe is provided below the limiting block.
[0013] It can be seen from the above description that the technical problem to be solved by this application can definitely be solved through the above technical solution of this application.
[0014] At the same time, through the above technical solutions, the utility model has at least the following beneficial effects:
[0015] The utility model presses the pressure rod inward to inject the saline in the liquid extractor into the dilution medicine bottle through the second liquid extraction tube. After the pressing is completed, the pressure rod is automatically reset under the elastic force of the reset spring, and the saline in the liquid container is extracted into the liquid extractor. This arrangement solves the problem that the existing liquid extraction method is time-consuming, labor-intensive, and has a cumbersome configuration process, which brings great inconvenience to medical staff.
[0016] The utility model only needs one puncture operation by providing the first liquid extraction tube, the second liquid passage port and the puncture tube. Before the liquid extraction is completed, it is not necessary to repeatedly puncture and extract the liquid from the liquid container, which can effectively reduce the risk of physiological saline contamination and ensure the safety of the use of physiological saline.

DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0023] Implementation Case 1
[0024] As attached Figure 1 and Figure 4 As shown, the utility model provides a technical solution: a rapid liquid extraction device, comprising a liquid container 1, and a liquid extraction mechanism 5 and an anti-reversal mechanism 7 located below the liquid container 1;
[0025] The surface of the liquid container 1 is provided with a scale mark 2, the bottom of the liquid container 1 is provided with a puncture tube 10, the surface of the puncture tube 10 is provided with a first liquid opening 11, a limit block 3 is provided below the puncture tube 10, a second liquid extraction tube 8 is provided on the right side of the liquid extraction mechanism 5, a liquid blocking clamp 6 is provided on the right side of the second liquid extraction tube 8, a dilution medicine bottle 9 is provided on the right side of the liquid blocking clamp 6, and a first liquid extraction tube 4 is provided below the limit block 3. By providing the first liquid extraction tube 4, the second liquid opening 503 and the puncture tube 10, only one puncture operation is required, and no operation is required before the liquid extraction is completed. Repeatedly puncturing and extracting the liquid container 1 can effectively reduce the risk of contamination of the saline solution, ensure the safety of the use of the saline solution, and prevent the puncture tube 10 from repeatedly puncturing the rubber stopper of the liquid container 1, which is very easy to be damaged and cause tiny rubber particles to fall off and be mixed into the prepared medicine solution and injected into the human body, causing embolism of tissues and organs with blood circulation. When the rubber particles are large or block important blood vessels, it may cause large-scale embolism of organs or seriously affect organ function, causing functional disorders or even death and other serious adverse consequences.
[0026] Embodiment 2
[0027] The solution in the first embodiment is further introduced below in combination with a specific working method, as described below for details:
[0028] like Figure 2As shown, as a preferred embodiment, on the basis of the above method, further, the liquid extraction mechanism 5 includes a hemispherical plug 501, a baffle 502 is connected to the bottom of the hemispherical plug 501, a second liquid port 503 is arranged below the baffle 502, a liquid extractor 504 is arranged below the second liquid port 503, a piston 505 is arranged below the liquid extractor 504, a pressure rod 507 is connected to the bottom of the piston 505, and a reset spring 506 is arranged on the outside of the pressure rod 507. By pressing the pressure rod 507 inward, the saline in the liquid extractor 504 is injected into the dilution medicine bottle 9 through the second liquid extraction tube 8. After the pressing is completed, the pressure rod 507 is automatically reset under the elastic force of the reset spring 506, and the saline in the liquid container 1 is extracted into the liquid extractor 504. This arrangement solves the problems that the existing liquid extraction method is time-consuming, labor-intensive, and has a cumbersome configuration process, which brings great inconvenience to medical staff.
[0029] like Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the anti-reverse mechanism 7 includes a liquid inlet channel 701, a spherical plug 702 is arranged on the right side of the liquid inlet channel 701, a limiting spring 703 is arranged on the right side of the spherical plug 702, and a liquid outlet channel 704 is arranged on the right side of the limiting spring 703.
[0030] From the above, we can know that:
[0031] The utility model aims at the technical problem that the existing extraction method is time-consuming, labor-intensive, and has a cumbersome configuration process, which brings great inconvenience to medical staff, and the operation of extracting physiological saline multiple times also increases the risk of contamination of physiological saline and liquid medicine; the technical solutions of the above embodiments are adopted. At the same time, the implementation process of the above technical solution is:
[0032] First, when preparing vasoactive drugs or configuring an analgesic pump and needing to extract physiological saline to dilute the medicine solution, the puncture tube 10 can be first inserted into the liquid container 1, and the bottom of the puncture tube 10 is connected to the first extraction tube 4, the other end of the first extraction tube 4 is connected to the extraction device 504, the right side of the extraction device 504 is connected to the second extraction tube 8, and the end of the second extraction tube 8 is connected to the dilution medicine bottle 9. When it is necessary to extract saline, the pressure rod 507 can be pressed inward to inject the saline in the extraction device 504 into the dilution medicine bottle 9 through the second extraction tube 8. After the pressing is completed, the pressure rod 507 is automatically reset under the elastic force of the reset spring 506, and the saline in the liquid container 1 is extracted into the extraction device 504 at the same time. This arrangement solves the problem of the time-consuming, heavy workload, and cumbersome configuration process of the existing extraction method, which brings great troubles to medical staff. The problem of great inconvenience is that through the hemispherical plug 501, when the saline in the liquid container 1 is extracted, the hemispherical plug 501 moves downward, and the saline is sucked into the inside of the extractor 504 through the first liquid extraction tube 4 and the second liquid passage 503. After pressing the pressure rod 507, the baffle 502 moves toward the first liquid extraction tube 4 under the action of pressure, and the hemispherical plug 501 blocks the first liquid extraction tube 4 to prevent the saline from flowing back. Through the anti-reverse mechanism 7, when the saline is injected into the dilution medicine bottle 9, the spherical plug 702 moves to the right under the action of pressure, and the saline flows out through the liquid outlet channel 704. After the injection is completed, the spherical plug 702 is reset under the action of the limit spring 703, blocking the liquid inlet channel 701 to prevent the liquid in the dilution medicine bottle 9 from flowing back. When the dilution is completed, the liquid blocking clamp 6 can be closed to stop the extraction.
[0033] Through the above configuration, the present application can certainly solve the above technical problems and achieve the following technical effects:
[0034] The utility model presses the pressure rod 507 inward to inject the saline in the liquid extractor 504 into the dilution medicine bottle 9 through the second liquid extraction tube 8. After the pressing is completed, the pressure rod 507 is automatically reset under the elastic force of the reset spring 506, and the saline in the liquid container 1 is extracted into the liquid extractor 504. This arrangement solves the problem that the existing liquid extraction method is time-consuming, labor-intensive, and has a cumbersome configuration process, which brings great inconvenience to medical staff.
[0035] The utility model only needs one puncture operation by providing the first liquid extraction tube 4, the second liquid passage port 503 and the puncture tube 10. It is not necessary to repeatedly puncture the liquid container 1 before the extraction is completed, which can effectively reduce the risk of physiological saline contamination and ensure the safety of the use of physiological saline. At the same time, it is prevented that the puncture tube 10 will be repeatedly punctured on the rubber bottle stopper of the liquid container 1, which is very easy to be damaged and cause tiny rubber particles to fall off and be mixed into the prepared medicine and injected into the human body, causing embolism of tissues and organs with blood circulation. When the rubber particles are large or block important blood vessels, it may cause large-area embolism of organs or seriously affect organ functions, causing functional disorders or even death and other serious adverse consequences.
[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
