Description

Insulin Syringe Structure

technical field

The utility model relates to a structure of an insulin syringe, in particular to a structure which, when the injection is finished, is set by means of a set of protective cover arranged outside the cylinder body, the cylinder body and the push rod are pulled back, and the needle can follow the cylinder body. It is retracted and accommodated inside the protective cap to form a convenient and safe insulin syringe structure.

Background technique

When the human body cannot secrete insulin or the tissues of the body do not respond to insulin, it will affect the glucose entering the muscle and fat tissue, so the glucose content (and blood sugar) in the blood will rise. When the blood sugar rises to a certain level, it exceeds the kidney When the limit of reabsorbing sugar is reached, the sugar will be excreted in the urine, which is commonly known as diabetes.

Therefore, for insulin-dependent patients who need to inject insulin subcutaneously, some syringes are equipped with protective devices to avoid the possibility of stabbing the human body due to the exposure of the needle during the operation.

Please refer to Fig. 6 and Fig. 7, it is a commonly used syringe structure 50 with a safety shield, wherein, the outer wall of the cylindrical tube 51 of the syringe 50 is covered with a safety shield 60, and the safety shield 60 is correspondingly located on At the upper end of the outer wall of the cylindrical tube 51, the protruding shaft 52 on the periphery is provided with a rail groove 61 that can be rotated left and right along the protruding shaft 52 and moved up and down, and the closing cover above the shield 60 is provided with an injection needle part 53 The fitted buffer hole 62 is rotated and pushed up the shield 60 after the hypodermic injection is completed, so that the rail groove 61 on the shield 60 is guided by the protruding shaft 52 on the cylindrical tube 51 to move upward and close accordingly The injection part 53 is used to avoid puncture injuries and prevent accidents, so as to ensure the safety of users and personnel handling medical waste.

However, the above-mentioned commonly used insulin syringes are complex in molding and have too many operating steps.

Contents of the invention

The purpose of this utility model is to provide a safe, easy-to-operate insulin syringe with simple components in order to overcome the above-mentioned defects.

In order to achieve the above purpose, the utility model provides an insulin syringe structure, which comprises: a cylinder body with a chamber for containing medicine, a push rod accommodated in the cylinder body for pushing medicine, an embedded It is composed of a needle seat set on the front end of the barrel for the needle sleeve, a set of needle sleeve set outside the needle, and a set of cover placed at the end of the push rod. The above-mentioned components form an insulin syringe structure. The main improvement is that :

The front end of the barrel and the nesting part of the needle seat are sleeved with a positioning piece, and a protective cover is set outside the barrel, and a fitting part with a larger aperture is arranged inside the end of the protective cover, and the end of the cover is inward. There is a rib that makes the front end of the protective cover just touch the needle seat, so that the protective cover is sleeved on the outside of the cylinder;

The outer side of the part, and through the rib and the end of the positioning part to form a locking position, so that the needle can be accommodated inside the protective cover with the pulling of the cylinder, forming a simple, fast and safe insulin syringe structure.

In other words, it is mainly provided with a protective cover on the outer casing of the cylinder, and a large-diameter accommodating space is provided inside the end of the protective cover, and a rib is provided inwardly at the end of the cover to form a fitting part, which can be used for injection. At the end, the user can hold the outside of the protective cover with one hand, and pull the barrel and the push rod back with the other hand. This force can just make the fitting part at the end of the protective cover slide into the outside of the positioning piece at the front end of the barrel. , and through the rib and the end of the positioning piece to form a locking position, so that the needle can be accommodated in the protective cover as the cylinder is retracted. Safe insulin syringe structure.

Known from the above description, the utility model can achieve the following effects compared with the prior art:

1. Safety: Since the protective cover is set on the outside of the barrel of the utility model, the barrel and the push rod can be pulled back after the injection, so that the fitting part at the end of the protective cover and the positioning piece at the front end of the barrel can be closed. They are fitted and fixed with each other, and the needle can be accommodated in the protective cover as the cylinder is pulled and retracted, so as to prevent the needle from hurting people, so as to achieve the effect of safe use and recycling.

2. Simple operation: Due to the embedded positioning formed by the fitting part at the end of the protective cover of the utility model and the end of the positioning part, when the pull cylinder is pulled backward, the fitting part is slid on the outside of the positioning part, and The ribs of the fitting part and the positioning seat are locked against each other, so that the needle is accommodated in the protective cover. The operation is simple and safe, and the overall structure is truly creative and has excellent usability benefits.

3. Simple components: the protection cover and the positioning part of the utility model are simple in structure and easy to form, and indeed have industrial applicability benefits.
