Description

A kind of Painless Muscle Injection pump with heating massage function
Technical field
The invention belongs to medical auxiliary apparatus technical fields, especially relate to a kind of nothing with heating and massage functions Pain intramuscular injection pump.
Background technique
Now, administered intramuscular mode is essential in the treatment, has a wide range of application.Nurse executes muscle at work It is higher to inject the frequency, and was all in the past that nurse is completed to operate with manpower.The technical key point for grasping Silent Neuritis intramuscular injection is " two Fast one is slow ", that is, inserting needle speed wants fast when injecting, and injection liquid speed is slow, and pulling out needle speed will fastly, and there are many medical and nursing works at present Personnel cannot grasp the technical key point of inserting needle completely, this is the main reason for causing pain.On the one hand, patient it is strong to irritation, The painless injection demand of dosage slightly multiple medicine liquid is higher and higher, manually adjusted by nurse grasp at the uniform velocity, slowly skill have one Determine difficulty, and homogeneity cannot be reached.On the other hand, injection site hot compress is given before intramuscular injection, helps to improve part Blood circulation promotes medical fluid to absorb, and mitigates pain;When intramuscular injection, nurse makes the movement of part massage of hand, helps to disperse Patient's attention mitigates patient pain.There is a kind of needleless painless syringe currently on the market, is a kind of setting by pressure injection It is standby, after so that liquid drug is passed through a superfine hole by high pressure, a liquid column is generated, skin is penetrated and is ejected into subcutaneously, only It is to be widely used in insulin, the injection of the gobbets drug such as vaccine, big quantity of fluid does not have temporarily.
Therefore, in order to mitigate workload of the nurse, patient pain is reduced, it is next to need a kind of new technical solution in the prior art Solve the problems, such as this.
Summary of the invention
The technical problems to be solved by the present invention are: a kind of Painless Muscle Injection pump with heating massage function is provided, With heating and massage functions, the blood circulation of injection site part can promote before intramuscular injection and in injection process, promote medicine Liquid absorbs;Manually adjustable injection speed is at the uniform velocity injected by instrument, easy to operate, can not only mitigate patient pain, but also can be with Human ltc is saved, working efficiency is improved.
It is a kind of with heating massage function Painless Muscle Injection pump, it is characterized in that: include support frame, shell, control and Display screen, syringe needle adjusting knob, connecting line and vibration massage function patch, the side of the shell are provided with waveform hand-held part; One end of shell is arranged in support frame as described above;The vibration massage function is sticked the other end set in shell;The control and display screen The same side of shell is set with syringe needle adjusting knob;
The interior of shell be provided with syringe mounting rack, regulation handle gear, syringe, lead screw, syringe advance seat, Motor and battery, nearly support frame one end in the inside that the syringe mounting rack is fixed at shell, on syringe mounting rack It is provided with regulation handle gear;The syringe is arranged on syringe mounting rack;The lead screw is arranged in syringe mounting rack Lower part, one end of lead screw is connected to motor, and syringe advance seat is provided on lead screw;The upper end of the syringe advance seat is The propulsion boom end of L shape, L-shaped short side and syringe connects;Massage plaster one end is moved near earthquake inside the housing for the battery setting, And it is connect with motor by conducting wire;
The vibration massage function patch includes that Resistant heating piece, vibration motor and heating massage paste shell, and the heating is pressed Rubbing and pasting shell is truncated cone, and heating massage patch interior of shell center is provided with vibration motor, and vibration motor passes through connection Line and the battery of interior of shell connect;The Resistant heating piece is arranged in heating massage patch interior of shell along outer profile, is passed through Connecting line and the battery of interior of shell connect.
The regulation handle gear and the syringe needle adjusting knob of shell exterior connect.
Power switch and speed adjusting knob are provided on the control and display screen.
The vibration massage function patch from shell in use, can remove.
Through the above design, the present invention can be brought the following benefits: a kind of nothing with heating massage function Pain intramuscular injection pump, has heating and massage functions, can promote the blood of injection site part before intramuscular injection and in injection process Liquid circulation, promotes medical fluid to absorb;Manually adjustable injection speed is at the uniform velocity injected by instrument, easy to operate, can both mitigate trouble Person's pain, and human ltc can be saved, improve working efficiency.
Further, the beneficial effects of the present invention are drive the design of lead screw and syringe using motor, it is ensured that note The injection process of emitter is uniform motion, significantly reduces and keenly feels to patient's bring;
The waveform hand-held part design used on shell, facilitates medical staff to operate, improves working efficiency;
The design of vibration massage function patch instead of manually carrying out muscle massage, can be such that patient muscle loosens, to subtract before the injection Light patient pain.

Specific embodiment
A kind of Painless Muscle Injection pump with heating massage function, as shown in FIG. 1 to 3, including shell 8, setting exist The support frame 1 of 8 one end of shell, plays a supportive role in intramuscular injection, and the control on shell 8 and display screen 11 and syringe needle is arranged in Adjusting knob 12, be arranged in 8 other end of shell vibration massage function patch 10, can the auxiliary heat of vibration massage function, be internally provided with vibration motor 14 massage effects, heating massage patch 15 built-in resistor silk heating sheet 13 of shell play hot compress, and vibration massage function patch 10 is in not work Work is that can link together with shell 8 for an entirety, and when work removes, and the position injected is being needed to be heated and massaged;
The syringe mounting rack 3 being arranged inside shell 8 is for installing fixed syringe 4, and regulation handle gear 3 is for adjusting Needle injection depth, lead screw 5 and syringe advance seat 6 are used cooperatively, for promoting and recalling syringe 4, motor 7 and lead screw 5 Connection, for push lead screw 5 rotate, by control and display screen 11 set injection speed, control inject emitter 4 into or recall, Battery 9 is rechargeable battery or common batteries, is powered for whole device.
The working principle of the invention and process are as follows: before carrying out injection operation, be first powered and carry out to vibration massage function patch 10 Syringe 4 with drug is put on syringe advance seat 6 by preheating 1 minute or so, according to the requirement of injection site, is adjusted Syringe needle adjusting knob 12 drives handle gear 3 to determine the injection depth of syringe needle, concurrently sets the fltting speed of syringe 4, then Vibration massage function patch 10 is removed, massage operation is carried out in injection areas, makes injection areas loosening all muscles, pass through control and display screen 11 adjust injection speed, finally quickly carry out penetrating operation, open injection switch, and motor 7 drives lead screw 5 to rotate, makes on lead screw 5 Syringe advance seat 6 along injection direction uniform motion, carry out injection work, extracted rapidly after the completion of to be injected, close power supply.
Design through the invention solves the problems, such as two: first is that the depth restriction of injection quickly can be penetrated and be pulled out Out, second is that drug at the uniform velocity can be injected.Medical worker is allowed easily to grasp the technical key point of Silent Neuritis intramuscular injection --- " two is fast One is slow ".
