Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, described a kind of nasal cavity two capsule treatment pump, comprise for be packed in nasal cavity to nasal cavity pressurization and to the pressurization of nasal cavity surface sustained-release administration to be positioned at when medicine bag 1, treatment choana opening part oral cavity for the fixing capsule 2 that prevents described pressurization and deviate from from nasal cavity to medicine bag 1 and with the chemical feed pipe 3 be communicated with respectively with fixing capsule 2 to medicine bag 1 that pressurizes.Described chemical feed pipe 3 is " Y " shape, the head end of two bifurcateds being separately positioned on " Y " shape chemical feed pipe 3 to medicine bag 3 and fixing capsule 2 that pressurize.Setting is embedded respectively for adding the pressurized capsule chemical feed pipe 31 of injecting medical liquid and the fixing capsule chemical feed pipe 32 for adding injecting medical liquid to fixing capsule 2 to pressurization to medicine bag 1 in chemical feed pipe 3 and " Y " shape bifurcated head end; The tail end of described chemical feed pipe 3 arranges the pressurized capsule dosing mouth 41 be communicated with pressurized capsule chemical feed pipe 31 and the fixing capsule dosing mouth 42 be communicated with fixing capsule chemical feed pipe 32 respectively.
During concrete use: first the head end of two bifurcateds of " Y " shape chemical feed pipe 3 is inserted in nasal cavity and cavum nasopharyngeum respectively, that is: insert nasal cavity by arranging pressurization to the divergent ends of medicine bag 1, the divergent ends arranging fixing capsule 2 is inserted in cavum nasopharyngeum.Meanwhile, the tail end of chemical feed pipe 3 is exposed to outside nostril, and certainly, now the pressurized capsule dosing mouth 41 of chemical feed pipe 3 tail end and fixing capsule dosing mouth 42 army are exposed to outside nostril.Then, connect the fixing capsule dosing mouth 42 be exposed to outside nostril, by fixing capsule chemical feed pipe 32, injecting medical liquid is added to fixing capsule 2, make full the filling of fixing capsule 2 rise by also holding in choana opening part and cavum nasopharyngeum.Connect the pressurized capsule chemical feed pipe 31 be exposed to outside nostril again and to medicine bag 1, injecting medical liquid is added to pressurization, make pressurization reach proper range to the pressure of medicine bag 1, hemorrhage or petechia effectively can oppress nasal cavity wound surface, now, due to the fixation of fixing capsule 2, pressurize and can not to deviate to medicine bag 1.
As shown in Figure 4, treat further to medicine bag 1 pair of nasal cavity slow release medicinal liquid to realize pressurization, described pressurization comprises half filter membrane cuff or microporous membrane cuff to medicine bag 1, and described pressurization is to when filling medicinal liquid in medicine bag 1, and medicinal liquid can slowly ooze out by the medicine micropore 01 that oozes on cyst wall.Concrete medicinal liquid comprises and is used for the treatment of hemorrhage hemorrhage or for the local anesthetic that eases the pain or analgesic or tranquilizer etc.Wherein, local anaesthetics or hemorrhage reach therapeutic effect by local action, and analgesic and tranquilizer are more absorbed as blood by mucosa or wound surface except local action, are worked by cental system.
In order to ensure the medicinal liquid of described half filter membrane cuff or microporous membrane, through oozing medicine micropore 01, to ooze out hourly velocity unlikely too fast, described pressurization is to the poor pre-moulding low pressure high power capacity cuff of the material preferred elastomeric of medicine bag 1, that is: overlap the elasticity of cyst membrane own poor, the blister cavities size of pottery capsule is determined in advance; Continue the hydraulic pressure be filled with in cuff in medicinal liquid cuff after medicinal liquid sharply increase when cuff is full of, meanwhile, the volume change of cuff blister cavities is very limited.Certainly, in order to ensure described pressurization to the compressing effect of medicine bag 1, predetermined pressurization wants appropriateness be greater than the volume of nasal cavity to medicine bag 1 blister cavities capacity, and saying accurately pressurizes all suitably will be greater than in length rugosity the volume that nasal cavity needs bearing area to medicine bag 1.
Being filled with the profile after medicinal liquid in order to make pressurization to medicine bag 1 blister cavities better to match to reach with nasal cavity spatial shape and oppress effect preferably, pressurizeing and preferably making head end in advance comparatively carefully, the circular cone cylindricality capsule that tail end is thicker to medicine bag 1.Like this, pressurizeing and being filled with the full rear profile of medicinal liquid expansion to medicine bag 1 is the larger circular cone cylindricality capsule in less tail end cross section, head end cross section, better compressing nasal cavity wound surface or petechia.And when pressurization not to add before injecting medical liquid inserts nasal cavity to medicine bag 1, the residual gas in capsule should be extracted out through pressurized capsule chemical feed pipe 31, make whole pressurization can be close to the head end of the pressurized capsule chemical feed pipe 31 being provided with pressurized capsule medicine feeding hole 10 to the cyst wall of medicine bag 1 outside.
Further, pressurize to the preferred concavo-convex alternate structure of the cyst wall outer surface of medicine bag 1, avoid some depressed area of nasal cavity to oppress poor effect.Like this, during the compressing of nasal cavity surface smoothing position, the concavo-convex alternate mutual extruding of cyst wall outer surface does not affect compressing effect, and just can reach preferably compression therapeutic effect during the compressing of nasal cavity surface indentation position.
In like manner, in cavum nasopharyngeum, safe fixed effect is reached in order to make fixing capsule 2, described fixing capsule 2 is the cuff compared with strong elasticity that cyst wall thickness is consistent, not by injecting medicinal liquid cyst wall during external force along fixing capsule chemical feed pipe 32 vertical direction uniform expansion, the frictional force of fixing capsule 2 and cavum nasopharyngeum inner surface is made to reach best.Meanwhile, the outer surface of fixing capsule 2 should make the soft capsule of frosting process, increases coefficient of friction.
During concrete enforcement, along with pressurization is oozed out to medicine bag 1 inner liquid medicine, pressurize and slowly to reduce to the pressure of the compressing of the wound surface on medicine bag 1 pair of nasal cavity surface or petechia, in order to ensure therapeutic effect, need be interrupted in good time to pressurization to adding the medicinal liquid that medicinal liquid supplements outflow in medicine bag 1.
As shown in Figure 6, add medicinal liquid in order to easy to pressurization in medicine bag 1, described pressurized capsule dosing mouth 41 connects to arrange and is used for continuing the controlled dosing pump 8 adding injecting medical liquid to described pressurization to medicine bag 1, and described dosing pump comprises mechanical pump and electronic pump.The speed of dosing pump 8 dosing, because of suitable to medicine bag 1 inner liquid medicine leaching rate with pressurization, is guaranteed to pressurize to the pressure of medicine bag 1 inner liquid medicine within suitable scope.
As shown in Figure 2, described fixing capsule 2 arranges tonic pipe 5 with pressurization to being communicated with between medicine bag 1, described tonic pipe 5 arranges pressure differential tonic valve 6, when fixing capsule 2 inner liquid medicine pressure be greater than pressurization to medicine bag 1 inner liquid medicine pressure and reach marginal value time, pressure differential tonic valve 6 is open, and the medicinal liquid in fixing capsule 2 is supplemented by tonic pipe 5 and enters pressurization to medicine bag 1; When fixing capsule 2 inner liquid medicine pressure be greater than pressurization be false to the condition that medicine bag 1 inner liquid medicine pressure reaches marginal value time, pressure differential tonic valve 6 cuts out, and tonic pipe 5 is blocked.
Concrete, the setting of tonic pipe 5 is making full use of further fixing capsule 2.The cyst wall of fixing capsule 2 is preferably compared with the cuff of strong elasticity, and the length of fixing capsule 2 can lengthen when implementing.Before being filled with medicinal liquid, the cyst wall of fixing capsule 2 is close to chemical feed pipe 3 head end and fixes capsule chemical feed pipe 32 bifurcated lateral wall, and actual blister cavities does not exist.When injecting medicinal liquid to fixing capsule 2, rely on fixing capsule 2 to form blister cavities receiving medical liquids compared with the cuff expansion of strong elasticity completely, after injecting amount of liquid medicine, fixing capsule 2 CF pressure is higher, is far longer than pressurization to the hydraulic pressure in medicine bag 1; Meanwhile, because the cyst wall of fixing capsule 2 compared with strong elasticity cushions the absorption of hydraulic pressure, the pressure of fixing capsule 2 pairs of cavum nasopharyngeum is not remarkable.
Described tonic pipe 5 has been communicated with fixing capsule 2 and has pressurizeed to medicine bag 1, and the pressure differential tonic valve 6 wherein arranged is one-way cock, only allows the medicinal liquid of fixing capsule 2 to pressurization to flowing in medicine bag 1.Like this, fix the effect that the medicinal liquid injected in capsule 2 plays medicinal liquid temporary reservoir cavity volume, pressurization being extended to needing the interval time of filling medicinal liquid in medicine bag 1, alleviating nurse to pressurizeing to the frequency adding injecting medical liquid in medicine bag 1, alleviating nurse job amount.Certainly, if employ dosing pump 8, the meaning of this structure just greatly reduces, can only be movable at needs of patients, as gone out to check, acts on during out-of-bed activity temporarily, time patient activity time belongings reduce, convenient convenient.
Described pressure differential tonic valve 6 open condition is that fixing capsule 2 inner liquid medicine pressure is greater than pressurization to medicine bag 1 inner liquid medicine pressure and reaches marginal value, when meaning is that fixing capsule 2 inner liquid medicine pressure in the specific implementation equals marginal value, the volume of fixing capsule 2 is also not less than cavum nasopharyngeum space, and fixing capsule 2 still can play and pressurization is fixed on the function that nasal cavity avoids deviating to medicine bag 1.
As shown in Figure 3, described fixing capsule chemical feed pipe 32 arranges pressure differential tonic valve 6 with being communicated with between pressurized capsule chemical feed pipe 31; When fixing capsule chemical feed pipe 32 inner liquid medicine pressure is greater than pressurized capsule chemical feed pipe 31 inner liquid medicine pressure and reaches marginal value, pressure differential tonic valve 6 is open, and the medicinal liquid in fixing capsule 2 is supplemented by partial fixing capsule chemical feed pipe 32, pressure differential tonic valve 6 and part pressurized capsule chemical feed pipe 31 and enters pressurization to medicine bag 1; When fixing capsule chemical feed pipe 32 inner liquid medicine pressure be greater than condition that pressurized capsule chemical feed pipe 31 inner liquid medicine pressure reaches marginal value be false time, pressure differential tonic valve 6 cuts out, and described fixing capsule chemical feed pipe 32 is blocked with being communicated with between pressurized capsule chemical feed pipe 31.
The meaning of above structure is equal in tonic pipe 5 effect arranging pressure differential tonic valve 6, just direct by the grafting of pressure differential tonic valve 6 between adjacent fixing capsule chemical feed pipe 32 and pressurized capsule chemical feed pipe 31, more succinctly, do not repeating herein.
As shown in Figure 5, the activity of described fixing capsule chemical feed pipe 32 is embedded in the fixing capsule dosing chamber 33 of chemical feed pipe 3, and fixing capsule chemical feed pipe 32 can slide in fixing capsule dosing chamber 33; Described chemical feed pipe 3 tail end arranges fixed block 7 in the outlet of fixing capsule chemical feed pipe 32, and fixing capsule chemical feed pipe 32 can be fixed in the fixing capsule dosing chamber 33 of chemical feed pipe 3 by described fixed block 7 temporarily.
The main fork of " Y " shape chemical feed pipe 3 now branches into the branch arranging pressurized capsule chemical feed pipe 31, the lower semisection of " Y " shape chemical feed pipe 3 tail end is provided with a tract walked abreast with pressurized capsule chemical feed pipe 31 and defines fixing capsule dosing chamber 33.And namely the Ce Cha branch of " Y " shape chemical feed pipe 3 fixes capsule chemical feed pipe 32 activity and is embedded in fixing capsule dosing chamber 33, can slide in fixing capsule dosing chamber 33.Its meaning is: when some patient's nasopharyngeal air duct length variation is larger, can carry out suitable adjustment according to specific needs to the position of fixing capsule 2, and effect when fixing capsule 2 is worked reaches best.
Meanwhile, described chemical feed pipe 3 tail end arranges fixed block 7 in the outlet of fixing capsule chemical feed pipe 32, and fixing capsule chemical feed pipe 32 can be fixed in the fixing capsule dosing chamber 33 of chemical feed pipe 3 by described fixed block 7 temporarily.After the position adjustment of fixing capsule 2, fixed block 7 need be adjusted and make it play temporary fixed effect, the position of fixing capsule 2 is fixed, prevent the position of fixing capsule 2 from changing, the fixed effect of fixing capsule 2 is guaranteed.
Concrete, described fixed block 7 fixes the helical ring of capsule chemical feed pipe 32 exit outer wall for being arranged on chemical feed pipe 3 tail end, and described helical ring inwall is arranged and the ring screw fixing the protrusion that internal diameter that outside capsule dosing chamber 33, tube wall mates successively diminishes.When helical ring is along when fixing tube wall screw-in outside capsule dosing chamber 33, fixing capsule chemical feed pipe 32 is temporarily fixed in the fixing capsule dosing chamber 33 of chemical feed pipe 3 tail end; When helical ring is along when fixing tube wall back-out outside capsule dosing chamber 33, the fixing capsule chemical feed pipe 32 be temporarily fixed in the fixing capsule dosing chamber 33 of chemical feed pipe 3 tail end is loosened, and fixing capsule chemical feed pipe 32 can slide in fixing capsule dosing chamber 33.
Certainly, the detailed description of the invention of fixed block 7 has many, will not enumerate herein.Not to fill medicinal liquid in described fixing capsule 2, fix in capsule and can also fill gas when being communicated with to medicine bag 1 with pressurization; Gas, medicinal liquid even other liquid can be filled when not being communicated with to medicine bag 1 with pressurization.
Non-narcotic patient, only need the fixing capsule 2 not adding injecting medical liquid to insert in cavum nasopharyngeum, the pressurization not adding injecting medical liquid is inserted nasal cavity to medicine bag 1 simultaneously, now, the volume of two capsules is little, and patient's sense of discomfort is also difficult to stand frequently, can complete operation.When after appropriate medicinal liquid of annotating in fixing capsule 2, pressurizeing is fixed on nasal cavity to medicine bag 1; What then only need to continue slowly adds injecting medical liquid to pressurization in medicine bag 1, and pressurizeing constantly bulges to nasal cavity wound surface and petechia to medicine bag 1 constantly pressurizes, and pressure is now slow increase; Also do not have the point-like of operating theater instruments to touch and clamp, its pain is limited, and patient generally can tolerate simultaneously.
At the end of compression therapeutic, the medicinal liquid only need extracted out in fixing capsule 2 from fixing capsule dosing mouth 42 makes fixing capsule 2 sunken; Meanwhile, extract pressurization out to the medicinal liquid in medicine bag 1 from pressurized capsule dosing mouth 41, make pressurization sunken to medicine bag 1, just can easily this therapy equipment be extracted out from nostril, patient treatment side, completed treatment.
