Fig. 1-5 are referred to, the utility model provides a kind of technical scheme:A kind of regional anaest, including needle tubing 1, drug storage Pipe 2, draw pencil 3, closure 4, injection needle 5 and injection putter 6;The bottom of the drug storage pipe 2 is placed in needle tubing 1 and and needle tubing 1 inwall is slidably matched;The injection putter 6 includes piston rod 61 and piston 62;The piston 62 be located at drug storage pipe 2 in and with The inwall of drug storage pipe 2 is slidably matched, and drug storage space is formed between the bottom of the piston 62 and drug storage pipe 2;The piston rod 61 Bottom be connected on piston 62, the top of the piston rod 61, which is upward through the top of drug storage pipe 2 and slided with drug storage pipe 2, matches somebody with somebody Close;Connected between the top for drawing pencil 3 and the bottom of drug storage pipe 2, the bottom for drawing pencil 3 is passed down through needle tubing 1;Institute State closure 4 and be coated at the bottom for drawing pencil 3;The bottom of the needle tubing 1 is circumferentially evenly arranged with multiple pin holes 11;The injection Syringe needle 5 includes medicine feeding hole 52, catch 53 and the medicine outlet hole 54 set gradually along top to bottom;The medicine outlet hole 54, enter medicine Hole 52 and the connection of the bottom of drug storage pipe 2, the medicine feeding hole 52 are inserted in pin hole 11 and can moved down with drug storage pipe 2 and passed to needle tubing Outside 1, the catch 53 is connected with the bottom of drug storage pipe 2, and be cased with two ends outside the injection needle 5 connects with catch 53 and needle tubing 1 respectively The withdraw of the needle spring 51 connect.First closure 4 is removed when using, disposable aspiration needle is loaded onto on pencil 3 drawing, injection putter 6 is twitched Arcotic is sucked by drug storage space 63 by disposable aspiration needle, excludes after air, disposable aspiration needle is removed, closure 4 is covered Sealing.Skin damaged position is carried out disinfection and analgesic is oppressed, then needle tubing 1 is vertically arranged in skin damaged position, drug storage pipe 2 is pressed, injected Syringe needle 5 is pierced into skin corium, while promoting injection putter 6, arcotic is injected into patient's skin corium.Unclamp drug storage pipe 2, injection needle 5 extract in the presence of withdraw of the needle spring 51 from patient skin, complete anesthesia.Due to being hidden in needle tubing 1 using preceding injection needle 5 In, it is to avoid infant is frightened, cry and scream, and facilitates doctor to operate.Pressing drug storage pipe 2 is punctured, and is realized certainly by withdraw of the needle spring 51 The dynamic withdraw of the needle.Operating time is short, realizes that quick piercing is subcutaneous and quickly exits, punctures pain unobvious.
As the further improvement to above-mentioned technical proposal, concave up groove is provided with the bottom center of the needle tubing 1 12;The bottom for drawing pencil 3 is extended in groove 12;The closure 4 is integrally located in groove 12.Put down the bottom surface of needle tubing 1 It is whole, infant comfort is improved, facilitates doctor to operate.
As the further improvement to above-mentioned technical proposal, when the withdraw of the needle spring 51 reaches compression limit, the injection Syringe needle 5 stretches out the bottom 1-1.5mm of needle tubing 1.Meet ergonomics, prevent injection needle 5 is pierced into too deep, mistake notes arcotic Enter intravascular, be easy to doctor to operate.
As the further improvement to above-mentioned technical proposal, the drug storage pipe 2 also includes connecting and position with drawing the slip of pencil 3 In the needle cover 21 in drug storage pipe 2 and enter medicine spring 22;It is described enter medicine spring 22 be coated at draw on pencil 3 and two ends respectively with pin Lid 21 and needle tubing 1 are connected;The needle cover 21 is provided with top sealing and the sealing hole 211 being uniformly distributed circumferentially from the bottom to top;Institute The top fit with injection needle 5 under the nature of sealing hole 211 is stated, medicine feeding hole 52 is closed, the stress of needle cover 21 is moved up backward It is dynamic to make that sealing hole 211 departs from injection needle 5 and medicine feeding hole 52 is connected with drug storage pipe 2.After injection needle 5 is pierced into skin, enter Medicine spring 22 is compressed to critical value by needle cover 21, and the bounce-back of medicine spring 22 makes needle cover 21 be separated with injection needle 5, makes injection needle 5 Connected with drug storage pipe 2.Prevent that medicine oozes out needle tubing 1 when injection needle 5 is not pierced into skin, according into waste.
As the further improvement to above-mentioned technical proposal, the drug storage pipe 2 also includes locking pin 23 and and locking pin The locking slot corresponding with locking pin 23 is provided with the locking spring 24 of 23 connections, the needle cover 21;The locking pin 23 is certainly It is caught under right state in locking slot and locks needle cover 21.Nature locking pin 23 locks needle cover 21, makes medicine feeding hole 52 closed, Drug leakage is prevented, causes to waste.Injection putter 6 is promoted when using, needle cover 21 is moved down with drug storage pipe 2, compressed into medicine spring 24, After the decrement for entering medicine spring 24 reaches critical value, needle cover 21 is separated in the presence of medicine spring 24 is entered with injection needle 5, Medicine feeding hole 52 is set to be connected with drug storage pipe 2.
Be cased with as the further improvement to above-mentioned technical proposal, outside the piston rod 61 two ends respectively with drug storage pipe 2 and What piston 62 was connected pushes away medicine spring 64.Compressed drawing arcotic pusher medicine spring 64 by piston 62, one is produced to piston 62 Thrust, is covered after closure 4, and drug storage space 63 forms a confined space.Injection needle 5 is pierced into after patient skin, patient's Hypodermis is connected by injection needle 5 with drug storage space 63, and confined space is destroyed, in the presence of the thrust of medicine spring 64 is pushed away Piston 62 compresses drug storage space 63 automatically, by infusion of medicine patient skin, shortens the operating time, mitigates patient suffering.
As the further improvement to above-mentioned technical proposal, the top of injection putter 6 sets cartoon head portrait.Cartoon head portrait Infant can be attracted to note, it is to avoid infant is cry and screamed, facilitate doctor to operate.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above, for For those skilled in the art, it is clear that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and without departing substantially from this In the case of the spirit or essential attributes of utility model, the utility model can be realized in other specific forms.Therefore, no matter From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is by institute Attached claim rather than described above are limited, it is intended that will fall in the implication and scope of the equivalency of claim All changes are included in the utility model.Any reference in claim should not be considered as to the right involved by limitation It is required that.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art It may be appreciated other embodiment.
