Description
Technical Field
The utility model relates to an auxiliary device for rapidly removing a syringe needle, and belongs to the technical field of biochemical experimental equipment.
Background
Syringes are widely used in biological science, and the following are examples: transfection, the injector can be used for introducing exogenous genes or siRNA and other molecules into cells to realize transfection; vaccination, injection of a vaccine is commonly performed using a syringe to vaccinate humans and animals; cell culture, the syringe can be used for operations such as preparing culture medium, separating and re-suspending cells; the protein purification, the injector can be used for sample collection, washing, adsorption and other steps in the protein purification process; animal pharmacological studies the syringe may be used to inject drugs into experimental animals such as mice, rats, rabbits, etc., and to take blood samples.
A syringe is a medical device for injecting a liquid drug or other liquid substance. It generally consists of a movable piston, a needle and a syringe. By moving the plunger up or down, the volume of liquid in the syringe can be changed and the liquid injected into the human or animal body through the injection needle. Syringes are used for medical procedures such as drug delivery, vaccination, blood sampling, and have wide application in biotechnology and laboratory research. However, in the daily use of biotechnology, it is necessary for a person to manually insert the needle sheath back onto the needle and then rotate the needle sheath to remove the needle and discard it into the sharps container. Therefore, there is a need in the art for an auxiliary device for a syringe that can rapidly and safely discard a needle, and can obtain the effect of discarding the needle into a sharps container in one step, which is helpful for subsequent experimental operations, and can safely remove the needle, thereby improving the experimental work efficiency.
Disclosure of Invention
The technical problems to be solved by the utility model are as follows: the syringe auxiliary device can safely and quickly pull out the needle sleeve, and can discard the needle head into the sharp instrument box in one step, so that the experimental work efficiency and the safety degree are improved.
In order to solve the problems, the utility model adopts the following technical scheme: an auxiliary device for rapidly removing a syringe needle comprises a fixing device clamped on the outer wall of a syringe barrel of the syringe, wherein a raised auxiliary handle is arranged on one side of the fixing device, the fixing device is connected with the needle extraction device through a connecting part along the outer wall of the syringe barrel, a hole for sleeving an injection port of the syringe is formed in the needle extraction device, and the injection port is exposed from the hole and is connected with the needle.
The needle head can be safely and quickly pulled out through the utility model, so that the pollution caused by touching the needle head manually is avoided, the risk of hand being injured by the needle head is avoided, and the experimental safety and the working efficiency are improved.
The needle head removing device is used for rapidly removing the needle head, protecting the health and safety of an experimenter from being damaged by the sharp machine, and can be rapidly abandoned into the sharp machine box, so that the working efficiency of the experimenter is improved. The syringe is disposable, and the rest part of the syringe needle can be directly discarded into the medical waste barrel after the syringe needle is taken down, so that multiplexing is not needed to be considered.
The subsequent processing steps of the needle head of the existing injector in the cell biology are complicated, the application of the injector in different fields needs to be considered, the requirements of partial cell biology are not met, after the injector auxiliary device is adopted, the needle head can be directly pulled out, any risk of sharp instrument damage is avoided, and the experimental efficiency and the safety are greatly improved.
Drawings
Fig. 1 is a schematic view of an auxiliary device for rapidly removing a syringe needle according to the present utility model.
Detailed Description
In order to make the utility model more comprehensible, preferred embodiments accompanied with figures are described in detail below.
Examples
As shown in fig. 1, the utility model provides an auxiliary device for rapidly removing a syringe needle, which is characterized by comprising a fixing device 1 clamped on the outer wall of the syringe, wherein one side of the fixing device 1 is provided with a raised auxiliary handle 2, the fixing device 1 is connected with a needle removing device 4 through a connecting part 3 along the outer wall of a syringe, and the needle removing device 4 is provided with a hole for sleeving an injection port of the syringe, and the injection port is exposed from the hole and connected with the needle.
The device is produced together with a syringe, and the syringe packaging bag contains a syringe needle cylinder and a syringe needle without installation. In daily aseptic production, an operator opens a packaging bag, installs a needle head and uses the needle head according to experimental requirements; after the use, the syringe is aligned with the sharp instrument box and the auxiliary handle is pressed to rapidly pull out the needle. The section of the fixing device 1 is U-shaped and is in tight fit with the needle cylinder part of the injector, namely, the fixing device 1 is clamped on the outer wall of the needle cylinder, after the injector is used, downward pressure is applied to the auxiliary handle 2 to drive the whole device to be downward, and the connecting part 3 transmits force to the needle extraction device 4 to push the needle to be extracted, so that the needle is naturally dropped into the sharp box.
