Description

Technical Field

[0001] The present invention relates to the technical field of anesthesia devices, and in particular to an injection anesthesia device. Background Art

[0002] Anesthesia means using drugs or other methods to temporarily inactivate sensation in the patient, either overall or locally, to achieve painless surgical treatment. Currently, there are three main types of anesthesia: general anesthesia, local anesthesia, and spinal anesthesia. Anesthesiology is a science that uses the basic theories, clinical knowledge, and techniques of anesthesia to eliminate surgical pain, ensure patient safety, and create favorable conditions for surgery.

[0003] However, at present, hospitals usually use injections to deliver drugs when anesthetizing patients. Medical staff usually insert the needle manually during the injection process. Due to the different physical conditions of different patients, the required insertion depth is different. Medical staff have a certain degree of subjectivity when performing manual insertion and cannot accurately control the insertion depth, which may cause excessive or insufficient anesthesia in some parts of the body, resulting in poor anesthesia effect. At the same time, if the dose is insufficient during the injection process, it is inconvenient to take out the syringe and then replenish the fluid, which is easy to cause infection.

[0033] The end of the syringe 1 is fixedly connected to a sealing ring 103, and the outer surface of the sealing ring 103 is in contact with the limiting plate 301 sleeved on the outer surface of the needle 3. By setting the limiting plate 301, the needle 3 can be inserted into the syringe 1 for positioning. At the same time, the sealing ring 103 can increase the sealing between the needle 3 and the syringe 1.

[0034] The outer surface of the syringe 1 is provided with distance scale lines 101 and capacity scale lines 102, and the distance scale lines 101 and the capacity scale lines 102 are symmetrically arranged. The distance scale lines 101 and the capacity scale lines 102 can be used to control the length of the needle 3 and the injection dose. The outer side of the syringe 1 is provided with an indicator rod 405 for pointing to the distance scale line 101. The indicator rod 405 can facilitate a clearer view of the distance adjustment.

[0035] The limiting component 4 includes a sliding ring 401 that slides with the injection tube 1, and a threaded groove is provided on the outer surface of the sliding ring 401. The outer surface of the sliding ring 401 is provided with multiple groups of notches 402. The notches 402 can facilitate the up and down movement of the sliding ring 401 during the adjustment process. At the same time, when the sleeve 403 is screwed into the fixed sliding ring 401 and fixed, the notches 402 will be tightened, thereby fixing the position of the sliding ring 401 and the connecting plate 406. The outer surface of the sliding ring 401 is meshedly connected with the sleeve 403. The bottom surface of the sliding ring 401 is fixedly connected to two groups of connecting rods 404. The bottom ends of the two groups of connecting rods 404 are fixedly connected to the connecting plate 406. The setting of the connecting plate 406 can be used to limit the needle 3.

[0036] The top surface of the sleeve 403 is truncated into a cone shape, and the upper inner surface of the sleeve 403 is in contact with the outer surface of the injection tube 1. The sleeve 403 is used to fix the position of the sliding ring 401.

[0037] The support member 5 includes a support plate 501 that is slidably fitted into a groove 4061 formed on the outer surface of the connecting plate 406. The support plate 501 can be used to support the needle 3. The support plate 501 is arc-shaped, which can be easily adapted to the human body. A rubber pad 502 is fixedly connected to the outer surface of the support plate 501, and the rubber pad 502 is more comfortable in contact with human skin.

[0038] The adjusting assembly 6 includes two sets of screw rods 602 connected by a belt assembly 601. By setting the belt assembly 601, the two screw rods 602 can be driven to transmit synchronously at the same time. A protective shell 605 is provided on the outside of the belt assembly 601 to protect the belt assembly 601 and is also more beautiful. The screw rods 602 are arranged inside a square groove provided inside the connecting plate 406. One end of one set of screw rods 602 is fixedly connected to a rotating member 603. The outer surface of the screw 602 is meshedly connected to a push rod 604 that slides with the inner wall of the square groove. One side of the push rod 604 is fixedly connected to the support plate 501 and is connected to the support plate 501 through the push rod 604, so that the support plate 501 can be moved by moving the push rod 604.

[0039] The sealing member includes a sealing cap 8 threadedly connected to the infusion tube 7. The outer surface of the sealing cap 8 is fixedly connected to a sealing ball 801, and the sealing ball 801 fits against the inner wall of the infusion tube 7. During the injection process, the infusion tube 7 can be sealed to reduce the entry of external gas and viruses into the injection tube 1.

[0040] The switch assembly 9 includes a baffle 901 respectively arranged inside the injection tube 1 and the infusion tube 7, and a limit rod is provided on one side of the baffle 901 for limiting the direction of rotation of the baffle 901. Two sets of connecting blocks 902 are fixedly connected to one side of the baffle 901. The setting of the connecting block 902 is consistent with the side of the baffle 901 (such as Figure 8 (as shown in FIG) The opposite surfaces of the two sets of connecting blocks 902 are fixedly connected to round rods 903, and the outer surfaces of the round rods 903 are sleeved with rotating blocks 904. The rotating blocks 904 are respectively fixedly connected to the inner walls of the injection tube 1 and the infusion tube 7. The outer surfaces of the round rods 903 are sleeved with elastic members 905;

[0041] Among them, the elastic member 905 is configured as a torsion spring, one end of the elastic member 905 is fixedly connected to the connecting block 902, and the other end is fixedly connected to the rotating block 904. The setting of the elastic member 905 can make the baffle 901 in a Figure 8 Position in

[0042] Specifically, when medical personnel need to use the above device, they first loosen the sleeve 403 according to the required insertion length of the needle 3. At this time, due to the setting of the incision 402, the sliding ring 401 can move up and down. The required movement length is set according to the distance scale line 101 pointed by the indicator rod 405, and the sleeve 403 can be tightened to fix the sliding ring 401. At this time, the connecting plate 406 will limit the needle 3, which is convenient for controlling the insertion length of the needle 3. After the needle 3 is inserted, the injection tube 1 and the needle 3 need to be tilted during the refraction process. Before this, the rotation of the screw 602 can be driven by rotating the rotating member 603. , and then drive the push rod 604 to push the support plate 501. Since the support plate 501 supports the needle 3, the discomfort and uncontrollability caused by manual support can be reduced. When the dosage is insufficient in one injection, the sealing cap 8 is unscrewed out of the infusion tube 7, and then connected with the medicine bottle through the connecting tube, and then the piston rod 2 is pulled. At this time, due to the change in internal pressure, the baffle 901 in the infusion tube 7 rotates open, and the baffle 901 inside the injection tube 1 is closed due to the limit of the limit rod, and the liquid in the medicine bottle can enter the injection tube 1, reducing the need to pull out the injection tube 1 due to insufficient dosage, avoiding infection, and is also more convenient.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
