Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to a novel portable syringe. Background Art

[0002] When using a syringe, it is usually necessary to mix liquid medicine with powder medicine and inject it into the body. When mixing the liquid medicine with powder medicine, it is necessary to insert the needle into the medicine bottle and inject the liquid medicine into it to mix the liquid medicine with the powder medicine in the medicine bottle. However, traditional syringes have the following shortcomings: when a traditional syringe injects liquid medicine into a medicine bottle, since the medicine bottle is a sealed environment, the air pressure in the medicine bottle will continue to increase, thereby exerting resistance on the liquid medicine in the syringe, making it impossible to continue to inject the liquid medicine. Generally, it is necessary to pull out the needle and shake the medicine bottle for the next injection. This injection method is time-consuming and labor-intensive, and therefore, it needs to be improved. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a novel portable syringe, which has the advantage of being convenient to use.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 6 As shown, the utility model provides a new portable syringe, including:

[0023] A syringe 1, a push ring 2 is fixedly installed above the syringe 1, and a liquid outlet tube 3 is fixedly installed below the syringe 1;

[0024] A mounting pipe 6 is movably sleeved on the outside of the liquid outlet pipe 3, a screening ring 7 is fixedly installed below the mounting pipe 6, and a liquid outlet pipe 2 8 is fixedly installed below the screening ring 7;

[0025] A partition plate 16 is fixedly installed inside the screening ring 7, an air-proof and water-permeable membrane 12 is fixedly installed on the upper left side of the partition plate 16, a waterproof and breathable membrane 13 is fixedly installed on the upper right side of the partition plate 16, a semi-arc block 14 is fixedly installed on the inner left side of the screening ring 7, a rectangular block 17 is fixedly installed on the left side of the partition plate 16, a movable groove 18 is opened inside the rectangular block 17, a limit block 19 extending to the lower side of the rectangular block 17 is movably installed inside the movable groove 18, and a stopper 15 located below the semi-arc block 14 is fixedly installed below the limit block 19.

[0026] When using a syringe to inject water into the medicine bottle, insert the needle 10 into the medicine bottle, and then push the push block 20 to move the piston 4 downward to push the liquid in the syringe 1 out of the interior of the screening ring 7, and transport the liquid to the left side of the screening ring 7 through the air-proof and water-permeable membrane 12 and the waterproof and breathable membrane 13 installed in the screening ring 7. When the medicine liquid contacts the block 15, the block 15 is pushed downward by gravity, so that the limit block 19 moves downward to stretch the return spring 21. When the liquid is discharged, the return spring 21 contracts and drives the block 15 back to its original position. The discharged liquid is injected into the medicine bottle through the needle 10, and the air in the medicine bottle is injected into the right side of the screening ring 7 through the air hole 11, thereby relieving the air pressure in the medicine bottle, making it convenient for medical staff to push out all the liquid in the syringe 1 at one time.

[0027] By installing a screening ring 7 under the syringe 1, the air-proof and water-permeable membrane 12 and the waterproof and breathable membrane 13 installed in the screening ring 7 screen the liquid, and the liquid is discharged from the inside of the medicine bottle through the needle 10, and the air in the medicine bottle is injected into the right side of the screening ring 7 through the air hole 11. Compared with the traditional syringe, this new portable syringe sucks the gas in the medicine bottle into the right side of the screening ring 7 through the air hole 11, thereby relieving the air pressure in the medicine bottle, making it convenient for medical staff to inject the medicine into the inside of the medicine bottle at one time.

[0028] The outer side of the second liquid outlet tube 8 is movably sleeved with a second mounting tube 9 , a needle 10 is fixedly mounted below the second mounting tube 9 , and an air hole 11 is opened on the right side of the needle 10 .

[0029] Since there is an angle at the bottom of the needle 10, there may be residual medicine when the medicine is sucked out. This can be done by separating the liquid outlet tube 2 8 and the mounting tube 2 9, installing the mounting tube 2 9 directly under the liquid outlet tube 1 3, tilting the medicine bottle, and sucking the medicine into the interior of the syringe 1 through the needle 10.

[0030] A rectangular block 17 is fixedly installed below the partition plate 16 , and the other end of the rectangular block 17 is fixedly installed on the lower side of the air hole 11 .

[0031] The liquid and the gas are separated by the rectangular block 17 to prevent the liquid and the gas from mixing and affecting the use.

[0032] A piston 4 is movably installed inside the syringe 1 , a connecting shaft 5 is fixedly installed above the piston 4 , and a push block 20 is fixedly installed above the connecting shaft 5 .

[0033] Push the push block 20, so that the connecting shaft 5 drives the piston 4 to move downward, and the liquid in the syringe 1 is discharged through the liquid outlet pipe 3.

[0034] Among them, a return spring 21 is elastically installed between the bottom side of the movable groove 18 and the bottom side of the limit block 19, and the liquid outlet pipe 1 3 corresponds to the installation pipe 2 9.

[0035] When the liquid medicine contacts the block 15 , the block 15 is pushed downward by gravity, so that the limit block 19 moves downward to stretch the return spring 21 . When the liquid is drained, the return spring 21 contracts and drives the block 15 back to its original position.

[0036] The working principle and use process of this utility model:

[0037] When using a syringe to inject water into the medicine bottle, insert the needle 10 into the medicine bottle, and then push the push block 20 to move the piston 4 downward to push the liquid in the syringe 1 out of the interior of the screening ring 7, and transport the liquid to the left side of the screening ring 7 through the air-proof and water-permeable membrane 12 and the waterproof and breathable membrane 13 installed in the screening ring 7. When the medicine liquid contacts the block 15, the block 15 is pushed downward by gravity, so that the limit block 19 moves downward to stretch the return spring 21. When the liquid is discharged, the return spring 21 contracts and drives the block 15 back to its original position. The discharged liquid is injected into the medicine bottle through the needle 10, and the air in the medicine bottle is injected into the right side of the screening ring 7 through the air hole 11, thereby relieving the air pressure in the medicine bottle, making it convenient for medical staff to push out all the liquid in the syringe 1 at one time.

[0038] Since there is an angle at the bottom of the needle 10, there may be residual medicine when the medicine is sucked out. This can be done by separating the liquid outlet tube 2 8 and the mounting tube 2 9, installing the mounting tube 2 9 directly under the liquid outlet tube 1 3, tilting the medicine bottle, and sucking the medicine into the interior of the syringe 1 through the needle 10.
