Description
Technical field
It is a kind of precisely hypodermic injection servicing unit specifically the present invention relates to technical field of medical instruments.
Background technology
Hypodermic injection is that decoction is injected into hypodermis.Common infusions position is upper arm and thigh lateral.With new technology
Weed out the old and bring forth the new, with the appearance of clinical practice new demand, carry out sentinel lymph node inspection using acoustic contrast agent is subcutaneously injected, have
Beneficial to the assessment of malignant tumour by stages, be conducive to the degree for instructing regional nodes to clean, be conducive to improving the postoperative life of patient
Bioplasm amount.The most important condition of sentinel lymph node Contrast-enhanced ultrasonography is that contrast agent is accurately expelled to local subcutaneous tissue, is made
Contrast agent is accurately back to lymph node by lymphatic vessel, realizes the Contrast enhanced imaging of sentinel lymph node.Therefore, hypodermic injection portion
Position has been not limited solely to the regular injection position of upper arm and thigh lateral, has expanded to other any positions of body surface, such as breast
Around room, neck portion etc..In view of skin different parts are touched a tender spot, the sensitiveness felt is different, and the elasticity of skin is different, hypodermis
Minimal thickness is different, and the routine made carries out hypodermic technology and is difficult to meet clinical demand.So, it is badly in need of that auxiliary dress is subcutaneously injected
Put, meet under conditions of different skin, realize and precisely, quickly, be easily subcutaneously injected.
Chinese patent literature CN101869734A discloses a kind of negative pressure adsorption type hypodermic injection unit, by adsorbent equipment,
Air compression plant, quick air releasing device and injection needle tube composition.Wherein absorber and air compressor is connected by tracheae, is passed through
Air compressor can extract the air in absorber rapidly, make to form negative pressure in absorber and then heave skin contraction, can lead to
Cross the bulge height that air compressor adjusts skin.Injection needle tube is tightly connected by syringe needle step and absorber, when skin is received
Syringe needle is penetrated in skin automatically when contracting is heaved, and then can carry out medicament injection.Quick air releasing device is made up of rubber stopper, when pulling out
When falling rubber stopper, air pressure reverts to atmospheric pressure in absorber, and skin diastole recovers smooth, and syringe needle is extracted from skin automatically.
There is obvious problem in the patent, first, it is all complete by negative pressure of vacuum that syringe needle, which enters skin and exits skin, in the patent
Into depth of needle control accuracy is not high；Second, resorption must be carried out before being subcutaneously injected subcutaneous blood is in exclude needle point
Guan Zhong, it is ensured that injection medicine is in subcutaneous compartment, rather than enters the circulatory system by blood vessel, causes malpractice；Third,
Subcutaneous and skin penetrating point is in subnormal ambient during drug injection.When medicine by the needle tubing of malleation enters hypodermis
Afterwards, skin surface can be drawn back into along gap around syringe needle；Simultaneously during the withdraw of the needle, medicine can also be by pin hole to skin
Exosmosis.So, it is difficult to realize and effect is subcutaneously injected.Meanwhile, the general dosage of medicine all very littles are subcutaneously injected, dosage control is required
Injection system in height, the patent is difficult to play a part of accurately controlling drug dose.Chinese patent literature CN205698759U
Disclose a kind of hypodermic injection skin fixator, including a flexible straw hat shape retainer body；The fixator sheet
Body includes crown and around the crown bottom the brim of a hat of one week；The lower surface of the brim of a hat sets the multiple suckers of a circle；Crown inner hollow；Crown
Top push can after upspring reset；A circle draw-string is set in the peripheral bottom of crown；Match somebody with somebody strainer on draw-string.The patent work is former
Reason is similarly under negative pressure state, its disadvantage is the same with patent CN101869734A again by negative pressure during injection.But
Accurate hypodermic injection servicing unit on the present invention separates hypodermis and muscle layer using negative pressure；Hypodermis is in during injection
Under normal pressure, realize and be precisely controlled drug injection amount；Self-closed injection site is realized after injection, hemostasis is realized, prevents
The only correlation function such as infection, possessing the product of correlation function at present, there is not been reported.
The present invention obtains following items subsidy：Promote 3 years action plans of City Hospitals clinical skill and clinical innovation ability
(16CR3105B)；Scientific and technical department of Medical College, Shanghai Communication Univ. technique transfers promotion project (ZT201710, ZT201711)；Shanghai

Crossing research fund (YG2015MS28)；Shanghai City health and Family Planning Committee's fund (201440290,201640043).
The content of the invention
The purpose of the present invention is that there is provided accurate hypodermic injection servicing unit for deficiency of the prior art.
To achieve the above object, the present invention is adopted the technical scheme that：A kind of precisely hypodermic injection servicing unit, it is described
Servicing unit is precisely subcutaneously injected to be made up of cylinder, exhaust apparatus, injection window and closing patch, the bottom of cylinder is open；It is described
Cylinder connection exhaust apparatus；The barrel of described cylinder is injected on window covered with closing patch provided with injection window；Closing
Patch is made up of adhesive plaster and adsorptive pads.
A kind of preferred technical scheme is：Described exhaust apparatus blocks up group by movable push bar, plug pipe, exhaust nozzle and glue
Into；Have at the top of described cylinder in exhaust hole, the bottom connection of exhaust hole and exhaust nozzle, exhaust nozzle and is pushed away provided with activity
Bar；The top of movable push bar is that spherical, middle part is that straight-bar, straight-bar lower end are that bulge loop, bulge loop lower end are turbination suspension member；Exhaust
Upper end in mouth is provided with plug pipe, and plug pipe sleeve is located at the middle part straight-bar of movable push bar；On the turbination suspension member of movable push bar
Set hangs with glue and blocked up, and glue is stifled to be matched with bulge loop, the turbination suspension member of movable push bar.
Another preferred technical scheme is：The barrel of described cylinder is provided with intake valve, the height of described intake valve
Degree is higher than injection window；Described exhaust apparatus is made up of piston, connecting rod and handle, and described piston is arranged in cylinder
