Abstract

A powder injection combined dosing injector assembly sleeve is characterized in that a sleeve body (5) is provided with a limit groove (4), and a clamping button (3) on a push handle sleeve (2) is embedded into the limit groove (4). The limiting grooves are symmetrically arranged on the sleeve body and have a two-section structure. An observation port (6) is longitudinally arranged on the sleeve body. The push handle sleeve (2) is connected with the push handle (1) into a whole. The solute bottle and the solvent bottle are both packaged in the sleeve body, and the medicine mixing and injection can be completed only by rotating the push handle twice and applying external force during injection, so that the integrity is good, and the operation is very convenient.

Description

Powder injection combination dosing syringe assembly set

technical field

The utility model relates to an assembly sleeve of a powder injection combination dosing syringe.

Background technique

The applicant once filed two patent applications on November 21, 2003, "Drug Storage Type Powder Injection Combination Dosing Syringe" and "Internal Pressure Storage Type Powder Injection Combination Dosing Syringe". It has been explained in the document. However, due to structural deficiencies, it is difficult for the nurse to grasp the force required to make the connecting tube pierce the sealing plug of the solute bottle and the piston of the solvent bottle simultaneously during specific operations, and the depth of needle insertion is also difficult to control. In addition, because the matching distance between the solute bottle and the solvent bottle is short, and it is not easy to achieve a tight fit, it is easy to shake. If an external force is accidentally applied during transportation, handling or use, the two will be separated from the damage or the solute bottle will be damaged. Premature conduction with the solvent bottle, and it is inconvenient for the nurse to operate.

Contents of utility models

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art, and provide a powder injection combination dosing syringe assembly set with stroke limit and self-locking functions, and easy to grasp the force and needle insertion depth.

The technical improvement of the utility model is that: a limit groove is provided on the sleeve body, and the snap button on the push handle sleeve is embedded in the limit groove.

The further technical improvement of the utility model is:

The limiting slots are arranged symmetrically on the casing and are of a two-stage structure. An observation port is longitudinally arranged on the sleeve body. The push handle cover is integrated with the push handle.

Due to the improvements made on the basis of the previous two patents, both the solute bottle and the solvent bottle are installed in one sleeve, and the cooperation between the button and the limit groove can control the force when the solute bottle and the solvent bottle are connected. It also has a self-locking function, which can prevent misoperation or damage during transportation, handling, and use. It is easy to grasp the depth of needle insertion and is more convenient to operate. From the perspective of the overall structure, it tends to be more reasonable, good in integrity, convenient and practical, and fundamentally solves the deficiencies in the prior art.

Detailed ways

As shown in Fig. 1 and Fig. 2, the utility model has a cylindrical sleeve body 5, and a position-limiting groove 4 is arranged on the sleeve body 5. This limiting groove 4 is two right-angled sections that communicate with each other, wherein the length of the longer part of the first section can meet the needle-shaped connecting tube 14 piercing the sealing plug 12 and the piston 9 at the same time; the longer part of the second section is easy for nurses to grasp Needle insertion depth, while the two shorter sections are designed for self-locking. For the convenience of grasping the mixing situation of solute and solvent, an observation port 6 is also provided on the sleeve body 5, and this observation port 6 can also be designed longer as shown by the dotted line in Figure 2, to observe that the connecting pipe 14 pierces the sealing plug 12 and The case of piston 9. Two snap buttons 3 are arranged symmetrically on the push handle sleeve 2 which is integrated with the push handle 1 , and the two snap buttons 3 are respectively embedded in the limiting groove 4 and are slidably matched with the limiting groove 4 . When the product leaves the factory, the snap button 3 should be located in the uppermost short part of the limit groove 4 to realize self-locking.

When in use, first turn the push handle 1 so that the button 3 is located at the uppermost end of the limit groove 4, press the push handle 1 with your hand, the button 3 moves along the limit groove 4 to the bottom end of the first section and stops, and the push handle sleeve 2 Apply pressure to the solute bottle 8, so that the needle-shaped connecting tube 14 fixed on the bracket 13 pierces the sealing plug 12 and the piston 9 at the same time as the bracket 13 slides, at this time, the liquid in the solvent bottle 8 will pass through the connecting tube 14 Enter the solute bottle 10 to dissolve the powder. Then take off the protective cover 7 at the front end, then the needle 16 can be inserted into the muscle or the rubber stopper of the infusion bottle, and the push handle 1 is rotated again to make the snap button 3 enter the second section of the limit groove 4, and continue to push the push handle 1 Make the piston 9 move downwards to press the mixed medicinal liquid to enter the human body or the infusion bottle through the needle 16, and complete one operation. Because the needle 16 is fixed with the support 11, the support 11 can slide upwards and make the needle 16 pierce the sealing plug 15 of the solute bottle 10 so that the needle 16 enters the human body or the infusion bottle through the needle 16 when piercing the muscle or the infusion bottle.

The solvent bottle 8 and the solute bottle 10 are all assembled in the sleeve body 5 and become a whole, which can only be used once and discarded after use. Therefore, it is actually a self-destructing syringe, and there is no possibility of cross-infection. question.

The utility model can have more embodiments, such as the limit groove 4 can also be designed as a structure embedded in the inner wall of the sleeve body 5; the cross section of the sleeve body 5 can be square, rectangular, oval, triangular, or five-square , Hexagonal, outer square and inner circle, etc. The observation port 6 can also be arranged symmetrically.
