Description

A new type of anesthesia syringe

technical field

The utility model relates to the technical field of medical equipment, in particular to a novel anesthesia syringe.

Background technique

In medical practice, anesthesia is a strict and extremely important operation technique before surgery. At present, clinically, patients need anesthesia before surgery. Most of the anesthesia methods are to inject anesthetics at the lumbar spine. Due to the special location of the injection, The needle tube is unstable and easy to shake, and the angle and depth of the injection are determined by the experience of the medical staff. It is very easy for the injection position to be inaccurate, which will affect the anesthesia effect, bring unnecessary pain to the patient, and also affect the medical staff. The personnel increase the work difficulty greatly, and the existing syringes do not have the function of filtering the impurities in the medicine, which also affects the anesthesia effect of the medicine. Therefore, solving the above problems has become a key research topic in the prior art.

Utility model content

The purpose of this utility model is to address the deficiencies of the above-mentioned prior art, and propose a new type of anesthesia syringe. When injecting, the angle and depth of the needle are stable and controllable, the operation is simple, and the impurities in the medicine can be filtered out, greatly reducing the It is difficult for medical staff to operate, which improves the effect of anesthesia and reduces the psychological burden of patients.

In order to achieve the purpose of the utility model, the utility model proposes a novel anesthesia syringe, including a syringe, a piston, a push rod, a needle seat and a handle, the inner wall of the syringe is slidably connected to the piston, and the piston is connected to the Push rod, the other end of the push rod is connected to the handle outside the syringe, the top of the syringe is provided with a needle seat, one end of the needle seat is provided with a filter core, and the other end is connected to the needle; the bottom of the syringe is provided with A depth ruler and a protractor, the depth ruler is provided with a scale and is slidably connected with the injection barrel, and the end of the depth ruler without scale is flush with the needle head; the protractor is semi-circular and fixed under the injection barrel, its A rotating shaft is arranged at the center of the bottom edge, and a supporting plate is hinged on the rotating shaft, and the supporting plate overlaps with the surface of the protractor in parallel.

Further, a scale is provided on the outer side of the tube wall of the syringe.

Further, a raised red mark is provided on the needle.

Further, the support plate is a telescopic structure, which includes an upper support plate and a lower support plate, the upper support plate is provided with external threads, and the lower support is provided with internal threads, and the upper support plate can be inserted into the lower support plate. In the support plate, the variation of the length of the support plate is adjusted by rotating the upper support plate.

The beneficial effects of the utility model are: the bottom of the injection cylinder is equipped with a scaled depth gauge, which is designed to be flush with the needle and slidingly connected with the injection cylinder. When the needle is close to the skin, the depth gauge is also close to the skin. When the needle extends into the skin, the depth gauge is pushed against the skin and slides in the opposite direction, so that by observing the change of the scale on the depth gauge, the depth of the needle entering the skin can be judged; the protractor is fixed on the bottom of the injection barrel, There is a rotating shaft at the center of the bottom edge, on which a supporting plate is hinged, and the supporting plate is designed to be parallel to the surface of the protractor. When preparing for injection, first adjust the angle between the supporting plate and the protractor according to the body part to be injected. , and then move the support plate close to the position to be injected, and without changing the angle between the support plate and the protractor, adjust the length of the support plate so that one end of the support plate is pressed against the skin, and then the needle is deep into the skin to start the injection. The angle of the needle is controllable, and the support plate also supports the purpose of supporting the syringe, making the syringe more stable to hold and not easy to shake; the injection volume of the anesthetic can be controlled through the design of the scale on the outside of the syringe wall ;Through the raised red mark on the needle head, it is easier to judge the direction of the needle tip on the needle head and prevent the direction of the needle tip from deviating from the set position; the design of the filter element at one end of the needle seat can effectively filter out the impurities in the medicine. In a word, when injecting, the syringe of the utility model has stable and controllable needle angle and depth, and is easy to operate. At the same time, it can also filter out impurities in the medicine, which greatly reduces the difficulty of operation for medical staff, improves the anesthesia effect, and reduces the psychological burden of patients. .
