Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a medicine preparation device. Background Technology

[0002] I. In clinical practice, many medications need to be mixed and dissolved before use. Currently, during the preparation of fluids, doctors sometimes require the extraction of a certain amount of solvent beyond the standard volume to ensure drug concentration or limit the patient's fluid intake, before mixing and infusing the medication. In such cases, nurses need to extract and discard the solvent before dissolving the drug. Clinically, nurses often need to discard 200ml, 100ml, etc., of solvent before preparing a single medication solution, which is time-consuming and labor-intensive.

[0003] When nurses prepare medication solutions, they need to use a syringe to draw up the solvent, then inject it into another container to dissolve the drug, and then draw up the dissolved drug solution again and inject it back into the original solvent, repeatedly drawing up and down between at least two containers. This increases the risk of drug contamination. Furthermore, many medications are now stored in rubber-capped bottles. When using a syringe to draw up the solution, uneven pressure requires nurses to hold the syringe plunger for an extended period and constantly monitor the patient to avoid drawing up too much medication. To address these issues, a new medication preparation device is proposed. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution: a liquid dispensing device, including an outer shell 1, a squeezing assist component 2 mounted on the outer shell 1, a long-nozzle syringe 3 mounted inside the outer shell 1, the long-nozzle syringe 3 cooperating with the squeezing assist component 2, and a double-headed adjusting needle 4 mounted at the lower end of the long-nozzle syringe 3.

[0020] The outer shell 1 and the compression assist component 2 of this utility model can be reused repeatedly after disinfection.

[0021] Specifically, the outer shell 1 includes an outer shell body 11, a limiting ring plate 12 is fixedly connected to the lower inner end of the outer shell body 11, a limiting protrusion ring 13 is integrally formed on the lower outer side wall of the outer shell body 11, an internal thread 14 is provided on the upper inner side wall of the outer shell body 11, and scale lines 15 are engraved on the outer side wall of the outer shell body 11.

[0022] Specifically, the compression assist component 2 includes a pull plate 21 and two sleeve plates 22. Both sleeve plates 22 are sleeved together with the outer shell body 11. Both sides of the two sleeve plates 22 are fixedly connected with push rods 23. The outer side wall of the push rods 23 is sleeved with a spring 24 between the two sleeve plates 22. The pull plate 21 is sleeved together with the outer shell body 11 and is located between the two sleeve plates 22. The pull plate 21 is pressed together with the lower end of the spring 24. A snap-fit ​​component 25 is assembled on one side of the pull plate 21 and cooperates with the outer shell body 11.

[0023] When the compression assist component 2 is in use, the pulling plate 21 is pulled and the position of pulling upward is determined by the cooperation of the pulling plate 21 and the scale line 15 according to the actual suction volume. At this time, the spring 24 is compressed. Through the elastic force of the spring 24, the two sleeve plates 22 and the two push rods 23 are moved upward, thereby squeezing the piston handle 32 to move upward and sucking up the medicine. When the lower sleeve plate 22 is in contact with the pulling plate 21, the suction ends.

[0024] Specifically, the snap-fit ​​assembly 25 includes a rotating disk 251 and an elastic snap-fit ​​plate 252. The rotating disk 251 is rotatably connected to one side of the pulling plate 21. The outer end of the elastic snap-fit ​​plate 252 is fixedly connected to the bottom surface of the rotating disk 251. The outer side wall of the elastic snap-fit ​​plate 252 has a snap-fit ​​groove 253 opened on the outer side wall of the outer casing body 11.

[0025] When the pulling plate 21 is pulled to the position where the liquid medicine is absorbed, the elastic clamping plate 252 will engage with the clamping groove 253, thus engaging the pulling plate 21 with the outer shell body 11. When the pulling plate 21 is pulled upward, the elastic clamping plate 252 will bend downward, thereby pulling the pulling plate 21. When the pulling plate 21 is moved downward, the rotating disk 251 is rotated to separate the elastic clamping plate 252 from the clamping groove 253.

[0026] Specifically, the long-nozzle syringe 3 includes a syringe housing 31, a piston handle 32 is sleeved inside the syringe housing 31, and sleeves 33 are integrally formed on both sides of the upper end of the piston handle 32. The two sleeves 33 are respectively sleeved to the upper ends of the two push rods 23. An extension connecting nozzle 34 is integrally formed at the lower end of the syringe housing 31. The lower end of the outer wall of the extension connecting nozzle 34 is sleeved to the limiting ring plate 12. An external thread 35 is provided on the upper end of the outer wall of the syringe housing 31. The external thread 35 is screwed together with the internal thread 14.

[0027] Specifically, the dual-head adjusting needle 4 includes a main connecting tube 41, the upper end of which is sleeved with an extension connecting nozzle 34. Two symmetrical needle connecting nozzles 42 are integrally formed on the outer wall of the main connecting tube 41. An L-shaped needle seat 43 is sleeved on each needle connecting nozzle 42, and a needle 44 is fixedly connected to the L-shaped needle seat 43. A ball valve 45 is rotatably connected to the lower end of the main connecting tube 41. An inlet channel 46 is fixedly connected to the upper end of the ball of the ball valve 45. The ball has a T-shaped channel 47 in the middle, which is connected to the liquid inlet channel 46. The T-shaped channel 47 is matched with two needle connectors 42. The bottom surface of the main connecting tube 41 is engraved with three alignment lines 48. The ball valve 45 has a moving handle 49 fixedly connected to the outside of the ball. The moving handle 49 is matched with the three alignment lines 48. Two of the three alignment lines 48 are respectively opposite to the two needle connectors 42, and the remaining alignment line 48 is located between the two alignment lines 48.

[0028] When the handle 49 is aligned with the alignment line 48 on the side of the needle connector 42, the needle connector 42 on the opposite side will be connected to the syringe housing 31. When the handle 49 is aligned with the alignment line 48 in the middle, both needle connectors 42 are connected to the syringe housing 31 at the same time, thereby realizing the adjustable function.

[0029] As shown in the figure, the L-shaped needle holder 43 is fitted with a cover to protect the needle 44.

[0030] Working principle: When using this utility model, the long-nozzle syringe 3 is fitted into the outer shell 1 and connected and fixed. At this time, the double-headed adjusting needle 4 is installed on the long-nozzle syringe 3 and inserted into the medicine bottle. The liquid in the two medicine bottles is adjusted according to the actual situation. At this time, the squeezing assist component 2 is adjusted according to the suction volume. The squeezing assist component 2 will squeeze the long-nozzle syringe 3 to draw and prepare the medicine. Therefore, it is not necessary to manually pull the syringe piston rod for a long time, nor is it necessary to repeatedly draw between multiple containers with one syringe needle. The medicine can be accurately prepared directly.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
