Abstract

The utility model provides an automatic muscle and subcutaneous tissue injector, which belongs to a medical device. A cylinder with an angle of 45 degree is formed by a bottom face and the bottom face of a side face. A direct current deceleration micro-motor is arranged in the cylinder. A motor axis is a screw thread axis with the covering of screw thread rings. A hollow cylinder is attached to the screw thread ring. A horizontal cylinder is covered on the left of the screw thread ring. A long rod is arranged in the hollow part of the screw thread ring. A pressure spring is arranged in the screw thread ring. A bite rodent cup and an occlusion rodent are arranged on the outside of the cylinder. The long rod is fixed and moved by pressing the bite rodent cup. A horizontal long rod, which is connected with a vertical spring clamp used for clamping the injector, is also arranged. The pressure spring and the cylinder shell of the occlusion rodent are arranged on both the lower part and the upper part of the horizontal long rod. When the arc pull handle on the shell is pulled outwards, the horizontal long rod moves upwards or downwards in a groove cylinder, so the injector is shot into or out of the muscle. An electrical machine is turned on; the screw thread ring is driven; the long rod in the cylinder is pulled and the medical liquid is injected into the muscle. The utility model is suitable for the self-operation by patients or family members or is used to operate a quick operation to the patient who is critically ill and can not cooperate with the operation; so the utility model provides convenience to nurse and reduces the workload.

Description

Automatic muscle, hypodermic syringe

Technical field:

This utility model belongs to medical apparatus and instruments: automatic muscle, hypodermic syringe.

Background technology:

Present clinical muscle, subcutaneous injection are 2ml, 5ml syringe, the fundamental operation care method of doing by professional nurse, patient does muscle, subcutaneous injection, must to hospital by professional nurse do operation treatment, muscle, subcutaneous injection operation, two fast one slow, inserting needle is fast, push away that medicine is slow, each nurse operation action is different, brings painful different to patient.

The utility model content: automatic muscle, the hypodermic syringe that the utility model proposes, its purpose at first solve patient and must go to hospital to do muscle, hypodermic problem, realize that patient and family members can oneself operate; Secondly to critical, rescue the patient that can not cooperate and implement quick operation, provide convenience and reduce workload to the nurse.

Technical solutions of the utility model: bottom surface and lateral bottom surface form the cylinder bodily form of miter angle, being positioned at the inside is direct current deceleration micromachine, motor shaft is positioned at the limit that takes over above the motor, motor shaft is a thread-shaped, overcoat is joined the fillet of screw that type is meshed, the right outside of the outer attached round of the fillet of screw, round is hollow, round is the empty shape face in the side of connection up and down, the left side is the circle macaroni, overlaps the traverse cylinder that matches, cylinder height and round equal diameters in left macaroni place and open circles body, be hollow the same in the middle of the cylinder with round upper and lower macaroni size position, cylindrical this head that is positioned at round is with compression spring, and the compression spring other end is attached to the right, open circles body the inside, and cylinder the outside is the medicated cap that gnaws, the outer attached interlock of cylinder is nibbled, the medicated cap that gnaws is nibbled with interlock and is matched, and is stock during cylinder side is hollow, and stock accounts for cylinder side's macaroni 1/2, stock the higher authorities are circular cap, the circular entity in other end; The attached cabinet of motor shaft, it between shell attached middle school the elongate recesses cylinder, the rounded nose of the horizontal shape stock of cover in the cylinder groove, the attached perpendicular shape spring clip in horizontal shape stock other end, horizontal shape stock has outstanding cylinder above the middle part, and the right is provided with tooth engaged in the middle of the cylinder, enclosure pressure spring on the cylinder, the compression spring overcoat is that the inside is provided with the cylinder blanket that the interlock down that matches is nibbled, and the compression spring other end is attached to bottom surface, cylinder blanket the inside, and the cylinder blanket outside is provided with arc pull handle.Horizontal shape stock has outstanding cylinder below the middle part, the right is provided with tooth engaged in the middle of the cylinder, enclosure pressure spring above the cylinder, the compression spring overcoat is that the inside is provided with the down interlock that matches and nibbles cylinder blanket, the compression spring other end is attached to bottom surface, cylinder blanket the inside, and the cylinder blanket outside is provided with arc pull handle.

Above-mentioned direct current deceleration micromachine 3 per minute rotating speeds and thread spindle 4 spacings, medicine enter intramuscular optimum speed and are complementary.

This utility model beneficial effect: i. with the tooth engaged interlock, makes stock up and down when pressing the medicated cap 8 that gnaws, and realizes that pushing away the medicine axle advances or go out; Move in groove when pulling the horizontal stock of arc pull handle, make entry needle in the muscle into ejection of being hit by a bullet; Open motor, thread spindle rotates the fillet of screw and hollow cylinder 6 is moved up and down, and medicine is pushed muscle, throws off with tooth engaged when the pressure medicated cap 8 that gnaws, and stock is fixed, and pushes away the medicine process, closes until finishing motor.Realize that thus patient or family members can carry out automatic muscle subcutaneous injection from line operate.In addition to critical, rescue the patient who can not cooperate and can implement quick operation, provide convenience and reduce workload to the nurse.Ii. compression spring elastic force all is directly proportional with pin is long with pin turnover power and groove length, to guarantee to realize injection, injection safety and comfortable not pain.Iii. as long as select the motor speed and the tooth pitch of suitable coupling, just can obtain medicine and enter the muscle optimum speed.
