Abstract
A high-pressure booster comprises a master collet, a bolt connected on the enclosed end of the master collet, and an end cap connected on the opening end of the master collet. The top face of the end cap is provided with through-holes, and one end of the bolt which is penetrated into the master collet is equipped with a plunger, wherein the plunger can rotationally connect on the bolt, and the peripheral walls of the plunger are engaged with the inner walls of the master collet which are provided with a guide slot along the axial direction. A guidance key which is engaged with the guide slot is arranged on the plunger. The plunger of the utility model just can move forwards and not rotate, therefore the push-rod of a disposal injector only withstands the forward thrust without torsion force effect, so the push-rod of injector can not deform and the soup can not seep backwards, which improves injection success rate, and applies conveniently. The utility model can appreciably improve curative rate, reduce cure times of patients and medical treatment charges, and relieve the sufferings of patients caused by the past cure method, which is worth wise to popularize.
Description
Technical field
This utility model relates to a kind of medical surgical instrument.
Background technology
To skin lesion tissue plumpness, densification, inflammatory, proliferative skin disorders, many as neurodermatitis, prurigo nodularis, keloid etc. with antihistaminic for oral administration, the topical class steroid hormone, treatments such as the ointment of salicylic acid medicine, plaster and dimethylsulfoxide treatment or employing surgical operation, carbon dioxide laser, liquid nitrogen freezing.Problems such as though these methods can obtain certain curative effect, it is slow to exist onset, and the course of treatment is long; Operative treatment exists painful big, the relapse rate height, and the patient is difficult for accepting shortcomings such as medical fee height.Micro-long-acting steroids hormonal medicaments is injected in chronic, inflammatory, the proliferative skin disorders skin lesion, utilize steroid hormone anti-inflammatory, anti-karyokinesis, be suppressed to the effect of fibroblast proliferation and reach fast, direct therapeutical effect.But because the skin lesion tissue is plump, fine and close, tough and tensile, adopt normal injection apparatus and technology, seriously restricting extensively carrying out of this method so far.Therefore, develop a kind of function admirable, be applicable to that the clinical high pressure booster of department of dermatologry shows important especially.
Referring to Fig. 1.Use more high pressure booster structure to comprise master collet 1 and screw rod 2 at present.Wherein the opening of master collet 1 is by the end cap 12 that has been threaded, and end cap 12 end faces are provided with central through hole, and all sides are provided with two opposed spacing holes; The blind end of master collet 1 is provided with the screwed hole that matches with described screw rod 2, and an end that stretches in the master collet 1 of screw rod 2 is fixed with plunger 4, and the other end is equipped with handwheel 3.During use, the exposed junction of push rod that installs the disposable syringe of medicine is stretched in the master collet 1, the ear handle of needle tubing right-hand member is stuck in the left end of master collet 1; Then end cap 12 is inserted in by the first end of syringe needle, make the ear handle of needle tubing place the spacing hole of end cap 12 after, tighten end cap 12; Tight syringe needle of handgrip and needle tubing afterwards, the another hands turns handwheel 3, and handwheel 3 drives screw rods 2 and plunger 4 and advances to left-hand screw with respect to master collet 1, thus the pushing syringe push rod injects patient part with the medicinal liquid in the needle tubing.In the above-mentioned use, when in scleroid skin lesion, injecting, because when pressure is big, disposable syringe needle tubing very easily occurs and expand to become big or syringe needle and needle tubing advance out phenomenon, for anti-phenomenon here takes place, must cause the inconvenience in the operation with a hand-tight syringe needle and a needle tubing of fastening during operation; And in the screw propulsion process of screw rod 2, because plunger 4 is fixed on the screw rod 2, also do the screw propulsion motion at frictional force effect lower plunger 4, this just easily causes torsional deformation, the syringe piston distortion of disposable syringe plastic push-rod, cause occurring oozing problem behind the medicine hands injection failure.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of injection success rate height is provided, the convenient high pressure booster that is suitable for.
This utility model high pressure booster comprises master collet, is connected the screw rod of master collet blind end and is connected the end cap of master collet opening that the end face of end cap has through hole, and an end that stretches in the master collet of screw rod is provided with plunger.Wherein said plunger is rotatably connected on the screw rod, and its periphery wall matches with described master collet inwall.Described master collet inwall in axial direction is provided with gathering sill.Described plunger is provided with the feather key that matches with gathering sill.
This utility model high pressure booster, wherein also comprising secondary sleeve, matches with the needle tubing of disposable syringe in this pair sleeve middle part, and the left part is connected with described end cap, the right part is connected with the left part of described master collet, and right part week side is provided with two opposed spacing holes.
This utility model high pressure booster, wherein said end cap is made up of gland with central through hole or eccentric through-hole and locking nut, locking nut is connected secondary telescopic left part, which is provided with spacing shoulder, and described gland is provided with the flange that matches with spacing shoulder.
This utility model high pressure booster, the perisporium of wherein said master collet is provided with slotted hole I vertically.
This utility model high pressure booster, the perisporium outer surface of wherein said master collet, contiguous slotted hole I position are provided with scale.
This utility model high pressure booster, the telescopic perisporium of wherein said pair is provided with slotted hole II vertically.
The advantage and the good effect of this utility model high pressure booster are: owing to be provided with gathering sill in master collet, plunger is provided with the feather key that matches with gathering sill, plunger is rotatably connected on the screw rod, so do the screw propulsion motion at screw rod, and plunger only moves forward, do not rotate, has only forward thrust so the push rod of disposable syringe bears, and there is not twisting force, so the push rod of syringe can not deform, medicinal liquid does not ooze after the meeting, has improved injection success rate, convenient being suitable for.
Other details of this utility model high pressure booster and characteristics can be cheer and bright by reading the embodiment hereinafter encyclopaedize in conjunction with the accompanying drawings.
