Description

Technical Field

[0001] The utility model relates to the technical field of sealing test, in particular to a device for testing the sealing of a drug injection point. Background Art

[0002] Testing the sealing properties of injection points is a crucial quality control step. It is mainly used to detect the ability of injection points to prevent drug leakage under various conditions. For example, in the medical field, if the injection point of an infusion device is not sealed properly, it may cause drug leakage, affecting the treatment effect and even causing serious consequences such as infection.

[0003] However, the prior art still has the following problems:

[0004] First, the existing technology for testing the sealing of injection points usually uses a manual squeeze test method. However, this method is less safe. If a leak occurs, the drug will directly contact the human hand, posing a safety hazard. In addition, the squeezing pressure control may not be accurate.

[0005] Secondly, the existing technology of the injection point sealing test is not convenient for limiting the position of the injection point. In this way, if the drug leaks, the leaked drug will spray out and easily splash onto the human body, which is not convenient for cleaning and poses a major safety hazard.

[0006] In response to the above problems, the inventors proposed a device for testing the sealing performance of injection points to solve the above problems. Utility Model Content

[0007] In order to solve the problems of poor safety of manual extrusion testing and inconvenience in limiting the position of the injection point, the purpose of the utility model is to provide a device for testing the sealing performance of the injection point.

After the medicine bag is placed, press down the lifting plate 3 to make the lifting plate 3 move downward between the four vertical rods 31, squeeze the medicine bag through the soft contact plate 37, and observe whether there is leakage at the injection point to determine whether the sealing is good. When squeezing is not required, the pins 33 on the two cross bars 32 are inserted into the two positioning blocks 34 to position the lifting plate 3 on the upper side of the bottom plate 1. The pins 33 can be removed when testing is needed. The overall structural design is simple and easy to operate, which greatly reduces the possibility of direct contact between the operator and the safety effect is good.

[0020] Both sides of the lower end of the limiting plate 21 are fixed with plug posts 22, and both sides of the upper end of the base plate 1 are provided with multiple column grooves 24 for use with the plug posts 22. The limiting plate 21 is installed by inserting the plug posts 22 into the corresponding column grooves 24. In this way, the appropriate spacing between the limiting plates 21 can be adjusted according to the different sizes of drug bags, thereby improving the versatility of the test.

[0021] Blocks 35 are fixed on both sides of both ends of the lifting plate 3, and a slot 36 for cooperating with the block 35 is opened at the inner end of the vertical rod 31. The lifting plate 3 can slide up and down between the vertical rods 31 by sliding the block 35 in the slot 36.

[0022] Example 2: Figure 3As shown, two vertical blocks 5 are fixedly provided on one side of the upper end of the base plate 1, and an L-shaped plate 51 is slidably provided on one side of the upper end of the base plate 1, and a T-shaped slider 52 is fixed on the lower end of the L-shaped plate 51, and a T-shaped slide groove 53 used to cooperate with the T-shaped slider 52 is opened on one side of the upper end of the base plate 1. The lower end of the L-shaped plate 51 is in movably contact with the upper ends of the two vertical blocks 5, and the injection point is placed in the two vertical blocks 5. The T-shaped slider 52 slides in the T-shaped slide groove 53, so that the L-shaped plate 51 can slide on the base plate 1. In this way, the L-shaped plate 51 is slid onto the two vertical blocks 5, and the injection point is stuck in the two vertical blocks 5. At this time, if the sealing of the injection point is not good, the medicine will flow out and enter the waste box 4 for collection. The position of the injection point can be effectively controlled, and the leaked medicine can be guided, thereby further improving the convenience and safety of the sealing test.

[0023] A waste box 4 is detachably provided at one end of the base plate 1, and clamping rods 41 are fixed on both sides of the upper end of the waste box 4. Two rectangular grooves 42 for cooperating with the clamping rods 41 are provided on one side of the upper end of the base plate 1. The installation of the waste box 4 is completed by inserting the clamping rods 41 into the corresponding rectangular grooves 42, making it easy to disassemble the waste box 4 and facilitate cleaning of leaked drugs.

[0024] Working principle: The base plate 1 is placed on the table for operation. First, the medicine bag is placed between the long plate 2 and the limiting plate 21. The long plate 2 and the limiting plate 21 can limit the medicine bag. The medicine pipeline can be transmitted through the through slot 23. After the medicine bag is placed, the lifting plate 3 is pressed down to move the lifting plate 3 downward between the four vertical rods 31. The medicine bag is squeezed through the soft contact plate 37. Observe whether there is leakage at the injection point to determine whether the sealing is good. When squeezing is not required, the pins 33 on the two cross bars 32 are inserted into the two positioning blocks 34 to position the lifting plate 3 on the upper side of the base plate 1. The pins 33 can be removed when testing is required. The overall structural design is simple and easy to operate, which greatly reduces the possibility of the operator directly contacting the medicine and has a good safety effect.

[0025] The limiting plate 21 is installed by inserting the pins 22 into the corresponding column slots 24. In this way, the spacing between the limiting plates 21 can be adjusted according to the different sizes of drug bags, thereby improving the versatility of the test.

[0026] By sliding the clamping block 35 in the clamping slot 36, the lifting plate 3 can slide up and down between the vertical rods 31;

[0027] The injection point is placed between the two vertical blocks 5, and the T-shaped slider 52 slides in the T-shaped slot 53, so that the L-shaped plate 51 can slide on the bottom plate 1. In this way, the L-shaped plate 51 is slid onto the two vertical blocks 5, and the injection point is clamped between the two vertical blocks 5. At this time, if the sealing of the injection point is not good, the medicine will flow out and enter the waste box 4 for collection. The position of the injection point can be effectively controlled and the leaked medicine can be guided, thereby further improving the convenience and safety of the sealing test;

[0028] The installation of the waste box 4 is completed by inserting the clamping rod 41 into the corresponding rectangular groove 42, so that the waste box 4 is easy to disassemble and the leaked medicine is easy to clean.
