Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a quantitative anesthesia injector, which includes a device main body 1, a drug inlet 2 and a support frame 3, wherein a drug outlet joint 101 is embedded in the left side surface of the device main body 1, the drug inlet 2 is embedded in the bottom end of the drug outlet joint 101, a sealing gasket 102 is embedded in the right side of the device main body 1, a sealing ring 103 is embedded in the outer side surface of the sealing gasket 102, the right side surface of the device main body 1 is fixedly connected with the support frame 3 through a thread, and the middle part of the right side surface of the support frame 3 is fixedly connected with an adjusting sleeve 4;

the top fixedly connected with snap ring 301 of support frame 3, the inner wall embedding of snap ring 301 is provided with packing ring 303, the bottom fixedly connected with handle 304 of support frame 3, the nested movable sleeve 401 that is provided with in lateral surface right side of adjusting collar 4, the right flank middle part of movable sleeve 401 runs through and is provided with the activity hole 404, the inside embedding of activity hole 404 is provided with bracing piece 402, scale interval 403 has been seted up in the front of bracing piece 402, the right side fixedly connected with handle 5 of bracing piece 402.

Further, adjust between cover 4 and the movable sleeve 401 through the threaded fixation, when the medicament ration of need to inject, the user can rotate movable sleeve 401 and move right through the screw thread for clearance between movable sleeve 401 and the handle 5 is adjusted, and can more accurately need the dose of regulation control through observing scale interval 403, makes to promote handle 5 and injects the in-process and can shelter from through movable sleeve 401, reaches the medicament dose of injecting and carries out quick control.

Furthermore, the upper side and the lower side of the cross section of the movable sleeve 401 are in a sawtooth shape, so that when a user rotates the movable sleeve 401, the hand and the outer side surface of the sawtooth-shaped movable sleeve 401 increase friction force, and the movable sleeve 401 is not easy to slip when rotated.

Further, fixedly connected with is the second spring 302 that the annular equidistance was arranged between snap ring 301 and the packing ring 303, and when the support frame 3 was handed to the user, the user pointed to and can insert in snap ring 301 further supported fixedly to support frame 3, and packing ring 303 can closely laminate user's finger lateral surface all the time through the elasticity of second spring 302, further increases the fastness between user's hand and the support frame 3.

Further, packing ring 303 is the rubber material, and the packing ring 303 of rubber material can have deformation for packing ring 303 can closely laminate the finger lateral surface, and soft packing ring 303 is difficult for causing the damage to the hand simultaneously.

Furthermore, the inner wall of the cross section of the gasket 303 is wavy, so that when the gasket 303 is tightly attached to a finger, a discontinuous gap is formed between the gasket 303 and the outer side surface of the finger, and the phenomenon that blood is blocked due to the fact that the gasket 303 clamps the outer side of the finger is avoided.

Furthermore, the supporting rod 402 penetrates through the supporting frame 3 and extends to the right side of the sealing gasket 102 in the device main body 1, when a user needs to use the device, the handle 5 is pushed to drive the supporting rod 402 to move leftwards so as to extrude the sealing gasket 102, and the sealing gasket 102 moves leftwards so as to enable the medicament in the device main body 1 to flow out through the medicament outlet joint 101.

Further, the first spring 104 is fixedly connected between the sealing ring 103 and the sealing gasket 102, the sealing ring 103 is made of friction-resistant rubber, the sealing gasket 102 moves leftwards and rightwards along the inside of the device body 1, the sealing ring 103 can be tightly attached to the inner wall of the device body 1 outwards through the elastic force of the first spring 104, liquid medicine in the device body 1 is difficult to leak rightwards through a gap between the sealing gasket 102 and the inner wall of the device body 1, and the injection dosage is inaccurate.

The working principle is as follows: when in use, when a user holds the support frame 3, the fingers of the user can be inserted into the snap ring 301 to further support and fix the support frame 3, and the washer 303 is always closely fitted to the outer side of the user's finger by the elastic force of the second spring 302, then, the user can rotate the movable sleeve 401 to the right by the screw, so that the gap between the movable sleeve 401 and the handle 5 is adjusted, then, the dosage to be regulated and controlled can be more accurately adjusted and controlled by observing the scale value 403, so that the movable sleeve 401 can shield the handle 5 in the process of injection, and finally, the sealing gasket 102 can move left and right along the inner part of the device main body 1, the sealing ring 103 is tightly adhered to the inner wall of the apparatus body 1 outward by the elastic force of the first spring 104, so that the liquid medicine in the device main body 1 is not easy to leak rightwards through the gap between the sealing gasket 102 and the inner wall of the device main body 1, and the injection dosage is inaccurate.

The embodiments of the present application have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
