Problems solved by technology

[0004] Most of the existing local infiltration anesthesia is carried out by injecting with a syringe. For people who need anesthesia in a large area or have a tall patient, one tube of drugs is obviously not enough. At this time, a second injection is required, which delays the best operation. Time is not conducive to the timely treatment of patients

Embodiment 1

[0029] see Figure 1~4 , in an embodiment of the present invention, an injection device for local infiltration anesthesia, including a syringe 1, a medicine box 2, a servo motor 5, a stirring shaft 6, a screw rod 15 and a rubber stopper 18; the side above the syringe 1 is fixed with a medicine box 2 , the upper side wall of the medicine box 2 is communicated with and fixed with a dosing pipe 3, wherein a sealing partition 4 is fixed inside the top of the medicine box 2, and a servo motor 5 is fixed on the outer flange of the upper end of the medicine box 2, and the output end of the servo motor 5 is rotated and connected to stir The shaft 6 and the stirring shaft 6 pass through the upper wall of the medicine box 2 and are rotationally connected with it. The servo motor 5 wire is connected to the power supply and the switch. Pressing the switch in the forward direction makes the servo motor 5 energized to drive the stirring shaft 6 to rotate in the forward direction, and pressin...

Embodiment 2

[0032] In order to further explain the above injection device for local infiltration anesthesia, the present application provides another embodiment, the injection device for local infiltration anesthesia in this embodiment has the following technical features: the injection port is sealed and connected with the injection hose 20, The end of the injection hose 20 is connected and fixed with a needle 21, and a sticker 22 is fixed on the side of the injection hose 20 close to the needle 21. The medicine extruded by the rubber stopper 18 enters the injection hose 20 through the injection port and then from The needle head 21 enters the body, and the needle head 21 is pasted on the epidermis of the patient through the adhesive tape 22, so as to facilitate the stability of the needle head 21.

[0033] According to the specific description of the above embodiment, it is easy to know that the working principle of the present invention is: press the switch in the forward direction to m...

Abstract

The invention discloses an injection device for local infiltration anesthesia and in particular relates to the injection device for the situation that a large amount of anesthetic is needed for a person who is big and tall or a relatively large local anesthesia area, aiming at solving the problems that a drug storage amount of an existing injection tube is limited in use, secondary injection is needed, the best operation time is delayed and in-time treatment of patients cannot be carried out. Specifically, the invention is characterized in that a servo motor is fixed on an outer flange of theupper end of a medical kit; an output end of the servo motor is in rotary connection with a stirring shaft; a plurality mixing blades are longitudinally arranged on the stirring shaft; a transmissionshaft is arranged at the outer part of the medical kit; the transmission shaft is connected with the upper part of the stirring shaft through a first synchronous belt; the lower end of a rotary shaftis fixedly connected with a first bevel gear; the first bevel gear is engaged with a second bevel gear; the second bevel gear is fixed on a screw rod; the front part of the screw rod is in thread connection with a thread sleeve rod; the thread sleeve rod is in sleeve joint with a retainer; a rubber plug is fixedly connected with the end part of the thread sleeve rod; the edge of the rubber plug isin sliding connection with an inner wall of an injector hermetically.

Description

technical field [0001] The invention relates to a medical device, in particular to an injection device for local infiltration anesthesia. Background technique [0002] Anesthesia is the temporary loss of sensation of the whole or part of the patient through drugs or other methods, so as to achieve the goal of painlessness and provide conditions for surgical treatment or other medical examination and treatment. Anesthesia is a variety of methods used to eliminate pain, ensure patient safety, and create good surgical conditions during operations or diagnostic inspections, and is also used to control pain. [0003] The most commonly used method in anesthesia is local infiltration anesthesia. Local infiltration anesthesia is to directly inject the local anesthetic into the surgical site and evenly distribute it in each layer of tissue in the entire surgical area to block the conduction of pain. It is a minor clinical operation. Commonly used methods of anesthesia. [0004] Mos...
