It is to connect with third connector 32, or connect with the 4th connector 42 that personnel can select the second connector 22 according to the actual situation
It connects.
In the technical solution of above-mentioned offer, as depicted in figs. 1 and 2, since second puncture needle 11 is set in the first puncture
Inside needle 11, when first puncture needle 11 punctures the eardrum of patient, first puncture needle 11 can drive the second of its inside to puncture
Needle 11 also punctures the eardrum of patient, and both first puncture needle 11 and second puncture needle 11 are only formed with one on the eardrum of patient
Puncturing hole, when needing to aspirate intratympanic hydrops or needing to Injection in Tympanic Cavity medical fluid, it is only necessary to select corresponding connector
(third connector 32 or the 4th connector 42) is connect with the second connector 22, and two are formed on eardrum without secondary puncture
Hole is caused outside medical fluid reflux to eardrum, will not secondary puncture to patient increase puncture pain.
It is aforementioned in order to realize specifically when implementing the technical solution of aforementioned auripuncture, Injection in Tympanic Cavity medical device 100
The function of negative pressure mechanism 31 and negative pressure generating device 312, the embodiment of the present invention have numerous embodiments, wherein in reality
In first example of existing negative pressure mechanism 31 and the function of negative pressure generating device 312: as shown in fig. 6, negative pressure mechanism 31 above-mentioned
It may include first sleeve (not indicated in figure).First sleeve has the inner cavity 311 of aforementioned negative pressure mechanism 31.The one of first sleeve
Hold the second opening 313 having inside connection.The other end of first sleeve is equipped with fourth hole 314.Negative pressure mechanism 31 passes through the
The open end of four through-holes 314 is connected with one end opposite with third groove 321 of the second through-hole 3211, so that the second through-hole 3211
It is connected to fourth hole 314, since the second through-hole 3211 is also connected to third groove 321, thus the second through-hole 3211, four-way
Hole 314 and third groove 321 are connected to.Negative pressure generating device 312 above-mentioned includes first piston 3121 and First piston bar
3122, first piston 3121 is placed in the inner cavity 311 of first sleeve, and is slidingly sealed cooperation with the cavity wall of inner cavity 311, this
" being slidingly sealed cooperation " refers to that first piston 3121 can not only be slided with respect to 311 wall of inner cavity of first sleeve, but also and first sleeve
311 wall of inner cavity seal cooperation, with enhance first piston 3121 aspirate when negative pressure tell on, prevent the inner cavity of first sleeve
311 gas leakage.One end of First piston bar 3122 is connect with first piston 3121, and the other end of First piston bar 3122 stretches out second
Opening 313, to facilitate medical worker to operate by the First piston bar 3122 to the suction of first piston 3121.This
In one example, when medical worker by First piston bar 3122 to 3121 applied force of first piston, keep first piston 3121 opposite
When 311 wall of inner cavity of first sleeve is displaced outwardly, negative pressure can be generated in the inner cavity of first sleeve 311.
Further, in first example, as shown in Figure 7 and Figure 8, the open end of fourth hole 314 and the second through-hole
3211 one end opposite with third groove 321 is an integral molding structure, to improve both first sleeve and third connector 32
Between connective stability.However, in an alternative embodiment, as shown in fig. 6, the open end of aforementioned fourth hole 314
It so can also also can achieve the 4th by flanged joint with one end opposite with third groove 321 of the second through-hole 3211
The technical effect that through-hole 314 is connected to the second through-hole 3211.Wherein, which kind of embodiment is specifically used, it can be according to user's
Actual demand setting, details are not described herein.
Negative pressure mechanism 31 above-mentioned and negative pressure generating device 312 can also be realized by other technologies scheme, specifically
In the second example of function for realizing aforementioned negative pressure mechanism 31 and negative pressure generating device 312: as shown in figure 9, above-mentioned negative
Press mechanism 31 includes the first container 301 made of elastic material, such as the first container made of rubber or silica gel material
301.The first container 301 has the inner cavity 311 of aforementioned negative pressure mechanism 31.Negative pressure generating device 312 above-mentioned is the first container 301
Itself, the first container 301 generates negative pressure in inner cavity 311 by the reply of self-deformation.Negative pressure mechanism 31 passes through the first container 301
It is connected with one end opposite with third groove 321 of the second through-hole 3211, so that the second through-hole 3211 and the first container 301 is interior
Chamber 311 is connected to.When user presses the first container 301, elastic deformation, the inner cavity of the first container 301 occur for the first container 301
311 volume reduces, and when unclamping the first container 301, the first container 301 is generated by the reply of self-deformation in inner cavity 311
Negative pressure, to realize the function of negative pressure mechanism 31 and negative pressure generating device 312.
Further, as shown in figure 9, auripuncture of the present invention, Injection in Tympanic Cavity medical device 100 further include elastic component
302, such as spring, elastic silica gel or elastic rubber etc..Elastic component 302 is arranged in the first container 301, and elastic component 302 is used for
Cooperate with the first container 301, to assist the reply of 301 self-deformation of the first container, the first container 301 is helped quickly to produce in inner cavity
Raw negative pressure.
It is aforementioned in order to realize specifically when implementing the technical solution of aforementioned auripuncture, Injection in Tympanic Cavity medical device 100
The function of syringe 41, the embodiment of the present invention have numerous embodiments, wherein the first of the function of realizing syringe 41
In example: as shown in Figure 10, syringe 41 above-mentioned includes second sleeve 411, second piston 412 and second piston bar 413.The
Two sleeves 411 have injecting cavity 4113, and one end of second sleeve 411 has the third opening 4111 inside connection, second sleeve
411 other end is equipped with injection port 4112 above-mentioned.Second piston 412 is placed in injecting cavity 4113, and with injecting cavity 4113
Cavity wall is slidingly sealed cooperation, and " being slidingly sealed cooperation " herein refers to that second piston 412 both can be interior with respect to second sleeve 411
Cavity wall sliding, and seal and cooperate with the internal chamber wall of second sleeve 411, the medicine liquid leakage in second sleeve 411 can be effectively prevented.
One end of second piston bar 413 is connect with second piston 412, and the other end of second piston bar 413 stretches out third opening 4111, with
Medical worker is facilitated to operate by the second piston bar 413 to the displacement of second piston 412.In second example, when
Medical worker, to 412 applied force of second piston, keeps second piston 412 interior with respect to second sleeve 411 by second piston bar 413
When cavity wall moves inward, the medical fluid in second sleeve 411 can be injected into the drum of patient from the second pin hole 211 of injection needle 21
It is indoor.
Syringe 41 above-mentioned can also be realized by other technologies scheme, specifically realize 41 function of said injector device
The second example in: as shown in figure 12, said injector device 41 may include second container 401 made of elastic material, such as
The second container 401 made of rubber or silica gel material.Second container 401 has injection port 4112 above-mentioned.When pressing second
It, can be by the medical fluid in second container 401 out of, the second pin hole 211 of injection needle 21 is injected into patient tympanum when container 401.
In the first example and the second example of the syringe 41 of aforementioned offer, as is illustrated by figs. 11 and 12, the 4th connection
