Description

Technical Field

[0001] The utility model provides an injection quantitative extraction container, belonging to the technical field of injection extraction auxiliary equipment. Background Art

[0002] Injections refer to sterile solutions (including emulsions and suspensions) made of drugs for injection into the body, as well as sterile powders or concentrated solutions for preparation into solutions or suspensions before clinical use. Injections act quickly and reliably, are not affected by pH, enzymes, food, etc., have no first-pass effect, can exert systemic or localized effects, and are suitable for patients who are not suitable for oral medication or cannot take oral medication. However, the development and production process of injections is complicated, and the safety and body adaptability are poor, and the cost is high. At present, after the injections are produced by pharmaceutical factories, they usually need to use injection extraction containers to extract them into the corresponding containers.

[0003] When extracting injections, existing extraction containers are usually operated manually by staff. This method has relatively strict requirements on the operators. Any carelessness will lead to inaccurate extraction of the injection, which has certain safety hazards and wastes medicines. The use of mechanical structures to assist extraction is too costly and is not suitable for most usage situations. Utility Model Content

[0007] Preferably: the fixing ring comprises a pair of mother-and-child rings symmetrically distributed on both sides of the straight cylinder, and a connecting rod corresponding to the adjusting threaded rod is fixedly connected to one side of one end of the mother-and-child rings close to the auxiliary plate, the adjusting threaded rod is inserted into the connecting rod and correspondingly engaged with it, and a corresponding locking nut is provided on the outer sleeve of the adjusting threaded rod.

[0027] like Figure 1 and Figure 2 As shown, a quantitative extraction container for injection includes a syringe body 1, a limiting structure 2 located on the outside of the syringe body 1, a straight cylinder 11 located on the syringe body 1 and placed between fixed rings 21, a piston rod 12 is provided inside the straight cylinder 11, and auxiliary plates 13 are fixedly connected on both sides of the opening of one end of the straight cylinder 11 close to the auxiliary ring 23, the limiting structure 2 includes a fixed ring 21 sleeved on the outside of the tube body part of the syringe body 1, and auxiliary rings 23 symmetrically distributed on both sides of the adjusting threaded rod 22 are connected to the fixing ring 21 through an adjusting threaded rod 22, and symmetrically distributed guide rails 24 are provided between the auxiliary rings 23 and the syringe body 1, and a limiting rod 25 is movably connected inside the guide rail 24.

[0028] In this embodiment, a limiting structure 2 is provided on the outside of the syringe body 1. The limiting structure 2 is fixed to the outside of the syringe body 1 by means of the cooperation between the fixing ring 21 and the adjusting threaded rod 22. By adjusting the length of the threaded rod 22, different types of syringes can be adapted. At the same time, with the help of a limiting rod 25 that slides freely in the guide rail 24, when the limiting rod 25 is fixed, the drug extraction of the syringe body 1 can be quantified.

[0029] like Figure 3 and Figure 4 As shown, the fixing ring 21 includes a pair of mother-and-child rings 211 symmetrically distributed on both sides of the straight cylinder 11, and a connecting rod 212 corresponding to the adjusting threaded rod 22 is fixedly connected to one side of the mother-and-child rings 211 close to the auxiliary plate 13 at one end. The adjusting threaded rod 22 is inserted into the connecting rod 212 and correspondingly engaged therewith, and a corresponding clamping nut 213 is sleeved on the outside of the adjusting threaded rod 22. A mounting ring 26 is fixedly connected between the auxiliary rings 23, and the mounting ring 26 is passed through by the adjusted threaded rod 22 and is close to the bottom plate of the guide rail 24. The guide rail 24 is placed between the auxiliary plate 13 and the mounting ring 26. A sliding groove 27 is provided inside the guide rail 24, and a limiting plate 241 corresponding to itself is provided inside the sliding groove 27. The limiting rod 25 passes through the limiting plate 241, and both ends of the limiting rod 25 are sleeved with locking nuts 242 placed on the outside of the guide rail 24.

[0030] In this embodiment, a scale corresponding to the locking nut 242 and the locking pressure piece is provided on the side wall of the guide rail 24 to assist in quantitative extraction; the position of the column limit rod 25 is fixed by the locking nut 242, and when the piston rod 12 in the syringe body 1 is driven to rise with the help of the auxiliary ring 23, the fixed position of the limit rod 25 can play a role in limiting the movement, thereby realizing the quantitative extraction of the syringe body 1; the parent and child ring 211 realizes its own fixation with the help of the mounting ring 26, the adjusting threaded rod 22 and the locking nut 213.

[0031] When using:

[0032] 1. Install the limit structure:

[0033] The limiting structure 2 is installed on the outside of the syringe body 1. The specific steps are:

[0034] The fixing ring 21 is sleeved on the outside of the tubular body of the syringe body 1 .

[0035] The fixing ring 21 and the auxiliary ring 23 are connected by adjusting the threaded rod 22 to ensure that the auxiliary ring 23 is symmetrically distributed with the syringe body 1 and can slide freely in the guide rail 24 .

[0036] 2. Adjust the length of the threaded rod:

[0037] The length of the threaded rod 22 is adjusted to suit different types of syringes. Ensure that the threaded rod 22 is inserted into and engaged with the connecting rod 212, and the externally sleeved compression nut 213 should be tightened to fix the length of the threaded rod.

[0038] 3. Set the limit rod position:

[0039] The limiting rod 25 is inserted into the sliding groove 27 of the guide rail 24 , so that both ends of the limiting rod 25 are sleeved on the locking nuts 242 arranged on the outside of the guide rail 24 .

[0040] According to the required extraction amount, the position of the limit rod 25 is adjusted to fix it at a suitable scale position, and the locking nut 242 is locked.

[0041] 4. Quantitative extraction of reagents:

[0042] After adjustment, the syringe is inserted into the produced injection.

[0043] The piston rod 12 in the syringe body 1 is driven to rise with the aid of the auxiliary ring 23 .

[0044] When the piston rod 12 rises to the position where the limiting rod 25 is fixed, the piston rod 12 will be restricted at this position, thereby achieving the purpose of quantitative extraction of medicine.

[0045] 5. Complete the extraction:

[0046] After ensuring that the quantitative extraction of the medicine is completed, loosen the locking nut 242 and move the limiting rod 25 out of the guide rail 24.

[0047] Remove the syringe and complete the entire quantitative extraction process.

[0048] 6. Cleaning and maintenance:

[0049] After use, the limiting structure 2 is removed from the syringe body 1 and cleaned and disinfected for next use.

[0050] These steps can help users accurately and quantitatively extract the injection, ensuring a consistent dose each time, which helps improve the accuracy and safety of the operation.

[0051] Although the present invention has been disclosed as above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
