Description
Technical field
The present invention relates to a kind of medicament sprayer, more particularly, to one kind can convenient, stably by multi-medicament component mist
The device changed, mix.
Background technology
In modern surgery operation, some medicines need to join to be used, such as Clinical practice fibrin sealant
(fibrin sealant), the key component of this product is the protein-based one-tenth such as Fibrinogen, the xiii factor, thrombin, fn
Divide and ca2+Deng salt ion composition, this pure biological product, simulate the final stage of body hemostasis and work, permissible
For stopping blooding, bonding, wound closure, wound healing etc..
Fibrinogen in fibrin sealant is the structural protein in Blood Coagulation Process mid-term Main Function, leads to
Crossing thrombin makes Fibrinogen hydrolysis fibroblast cells monomer, and this fiber monomer is condensed into little fiber, then again by
Gradually form the reticular fiber of three-dimensional.The xiii factor is in ca2+In the presence of.Activity form is changed into by thrombin hydrolytic scission.So
The active xiii factor being activated afterwards is converted into the non-covalent bond between the fiber monomer assembled covalently by transamination
Key.This reduces the sensitivity of the proteolytic digestion to fibrin solvent for the fiber gel, increase the total of gel simultaneously
Body intensity and dynamics so as to be adhere strongly on wet wound surface, formed a kind of semihard, hemostasis, immobilising viscous
Property material, play hemostasis and bonding wound effect.
Because the condition that Fibrinogen and thrombin react is room temperature, normal pressure, therefore, both can not mix in advance
Close, need to mix Fibrinogen and thrombin when using temporarily, and coat rapidly to wound surface.
In prior art, generally use double syringe blender as the applicator of bio-tissue binding agent, by fibre
Two kinds of drug components such as fibrillarin original solution and thrombin solution are added separately in different syringes, and drug component is released
Mix in same hydrid component afterwards, then spray atomization, medicinal liquid mixing as disclosed in cn2561423y, cn101554502a
Aerosol apparatus.There are some problems in the blender of this structure, as poor in atomizing effect, and the droplet size after atomization is larger；Next, by
It is much smaller than syringe intracavity diameter in dispersive nozzle diameter, releases extremely difficult during medicine, need to apply very big external force；Separately
Outward, after being applied to the pressure release of syringe, in syringe, syringe plunger can be rebounded certain distance by medicine resilience, releases
Injection volume is difficult to control to.

Specific embodiment
Embodiment 1
See figures.1.and.2, multicomponent pharmaceutical mixing sprayer of the present invention includes syringe part and aerosol apparatus part.
, syringe part includes two drug component syringes 11 and an air syringe taking three syringes as a example
12, air syringe 12 is located between two drug component syringes 11, but the present embodiment is not limited to three syringes,
As long as at least two drug component syringes 11 and at least one air syringe 12.
Referring to figs. 1 to Fig. 3, air syringe 12 and two drug component syringes 11 are fixed by fixing shell 10.
Drug component injector push-rod 110, the outer end of air syringe push rod 120 are linked together by integral piece 13, so permissible
Push or pull on the push rod of three syringes simultaneously；The head end of syringe is provided with fixture 14, and syringe is fixed by fixture 14
In fixing shell 10.
With reference to Fig. 3, fixture 14 can be the cylindrical structure of two ends insertion, and inner surface is provided with screw thread, and passes through thread bush
Put the head in centrally located syringe, such as outside air syringe liquid outlet 122.In addition, fixture can also be
Bore a hole including three, the head of three syringes passes in perforation.
In the present invention, fixing shell 10 can be two parts up and down fastening, and such as Fig. 4 gives a kind of fixing shell 10
Upper part-structure, lower partly can be symmetrical with it, it is fixing that two parts pass through multiple connectors 103.Fixing shell 10 includes
The outside framework 100 of the left and right sides, three syringes are located between outside framework 100.Between outside framework 100, it is provided with head limiting section
101 and afterbody limiting section 102.
Head limiting section 101, afterbody limiting section 102 include three curved portions, and three syringes are located at different curved portions
The inner recess space being formed.Head limiting section 101 is provided with baffle plate (not showing in accompanying drawing), baffle plate towards the side of blowing portion
It is provided with perforation, the head for syringe stretches out, but syringe tube is by baffle.Pass through plug-in unit between fixed mount 14 and baffle plate
Structure connects.
Blowing portion includes aerosol apparatus 2, and with reference to Fig. 5 to Fig. 7, aerosol apparatus 2 include shell 20, drug component passage 21, sky

Close.Mixing chamber 23 front end is provided with flow export 231, and the mixture in mixing chamber 23 enters spray nozzle by flow export 231
24 intracavity, is sprayed by top aperture 241.
The diameter of mixing chamber 23 is more larger than drug channel 21, and drug component enters and forms turbulent flow during mixing chamber 23, from
And there is good mixed effect, meanwhile, air participates in turbulent flow and mixing in mixing chamber, further increases mixing effect
Really.
In addition, in the case of pressing to push rod, the pressure pushing away before push rod usually makes medicine produce bounce, in addition, spray
Atomizing nozzle aperture 241 diameter very little, limited by drug flux, usually therefore leads in prior art be difficult to promote push rod and push rod
Bounce-back.But drug component syringe of the present invention and air syringe simultaneously in the presence of, the thrust of push rod and drug component
Bounce, is transferred to mixing chamber 23 by medicinal fluid passage 22, and passes to air in mixing chamber 23 further
Air in air syringe 12 is passed to by air duct 22, air has good compressibility, therefore, when promoting push rod
Substantially save external force it is easier to promote.
Additionally, in prior art, due to the elastic force of medicine, when stopping pressing to push rod, drug component also may proceed to from
Spray in spray nozzle aperture 241, exist delayed, but it was unexpectedly determined that drug component syringe of the present invention and air note
When emitter simultaneously promotion, once stopping promoting, then stop spraying at once, and push rod does not rebound.
And, air is compressed in mixture, after spraying through small holes 241, because pressure suddenly disappears, compressed air
Very fast collision, occurs " blast ", liquid is atomized further, improves atomizing effect.
