Moving cell 22, wherein the energy-storage units 21 are arranged between the vibration unit 22 and the medicinal liquid bottle, the vibration unit
22 activate under the driving of the power mechanism 23 and exert a force to the energy-storage units 21, the energy-storage units 21 with it is described
Medicinal liquid bottle is connected.To which medicinal liquid bottle is driven by the vibration unit 22 vibrates drug along linear direction.
In a preferred embodiment, the energy-storage units 21 are spring, and the telescopic direction of the spring is upper at this time
State linear direction.In order to realize that medicinal liquid bottle is connected with transmission mechanism, the spring pocket is loaded on the end of medicinal liquid bottle.The vibration
Unit 22 is hertz oscilltor.The power module can be rechargeable, or non-rechargeable.The power mechanism
23 be motor.
As shown in Fig. 3,4,5, the medical fluid imports head 10 and can be used in combination as bottle stopper or bottle cover with medicinal liquid bottle, energy
Cutaneous penetration is enough realized, with easy to use, and the advantages of cost is relatively low.
The medical fluid imports head 10 for realizing drug under medicinal liquid bottle vibrational state, protrudes into from described 20 one end of shell
Into the shell 20, and fill in or be set in the bottleneck of the medicinal liquid bottle in the shell 20.
Specifically, it includes: that medical fluid imports head ontology 1 and is set to the medical fluid importing head sheet that the medical fluid, which imports head 10,
Chip 2 on 1 end face of body.Preferably, it is plastic part that the medical fluid, which imports head ontology 1, and the medical fluid imports 1 one note of head ontology
It is moulded into type.
Wherein, the medical fluid importing head ontology 1 is open at one end, another to bring out liquid.The medical fluid imports the opening of head ontology 1
End forms installation end 11, in use, the installation end 11 that medical fluid imports head can be inserted into medicinal liquid bottle.Meanwhile in order to enable medicine
Liquid, which imports, has good leakproofness, to prevent leak-stopping liquid, the periphery wall surface or interior of the installation end 11 between head and medicinal liquid bottle
Sealing structure 12 is provided in peripheral wall surfaces.
In one embodiment, the sealing structure 12 be set to it is O-shaped on the periphery wall surface of the installation end 11
Sealing ring, correspondingly, offering the mounting groove of O-ring seal on the periphery wall surface or inner peripheral wall of the installation end 11.It is excellent
Selection of land, the O-ring seal are two, and two O-ring seals form double sealing structure 12.
In addition, it is additionally provided with limited step 14 on the periphery wall surface of the outlet end 13 of the medical fluid importing head ontology 1, the limit
Position step 14 can import head to the medical fluid being installed on medicinal liquid bottle and carry out axial limiting.
It offers to import inside head with the medical fluid on the end face of the outlet end 13 of the medical fluid importing head ontology 1 and be connected
Fluid hole 131, so that the medical fluid in medicinal liquid bottle can be flowed out from fluid hole 131 when medical fluid imports head and is inserted on medicinal liquid bottle.
In one embodiment, the fluid hole 131 is at least one, at least one fluid hole 131 is opened in the outlet end 13
End face marginal position, the chip 2 is set to the middle position of the end face of the outlet end 13.Preferably, the liquid out
The quantity in hole 131 is four.
The chip 2 is used for open the outmost cuticula of skin, while will not injure skin corium, to improve drug
Penetrating power.The chip 2 is set on the end face of the outlet end 13, and the chip 2 has the point arranged in the form of an array
Battle array structure.Preferably, the lattice structure is having a size of nanoscale micropin.In one embodiment, the chip 2 is with embedding
Conjunction mode is installed in the mounting groove on the end face of the outlet end 13, while being also filled between the chip 2 and mounting groove
Viscose glue.
In order to adjust the position that the medical fluid imports head 10, the medicinal liquid bottle of the inside of the shell 20 and it is matched therewith
Medical fluid imports head with movement travel axially and radially.In this way, the medical fluid, which imports head 10, to carry out axial direction with respect to shell 20
With radial adjusting, the i.e. three-dimensional regulation of XYZ in space.Wherein, axial adjusting can be by the installation site of change medicinal liquid bottle
It realizes, radial adjusting can import setting cushion block between head and shell 20 in medical fluid by setting and realize.
In addition, being also found surprisingly that, the liquid outlet quantity of fluid Supplying apparatus of the invention keeps phase with the variation of vibration frequency
Also have the advantages that liquid outlet quantity is constant to constant therefore of the invention fluid Supplying apparatus.Because according to habitual thinking, liquid out
Amount should increase with the increase of vibration frequency.However, it is possible to import structure of head etc. due in the present invention for medical fluid and carry out
Optimization design thereby reduces the influence of the variation of vibration frequency, so that liquid outlet quantity keeps relative constant, and then is conducive to skin
Absorption for medical fluid reduces waste.
Above-mentioned unexpected technical effect is verified below, the medical fluid of fluid Supplying apparatus of the invention is imported
The medical fluid of 7.18g is packed into head.By the way that the vibration frequency of basic, normal, high three gears is arranged, going out under different vibration frequencies is observed
Liquid measure situation.As a result as shown in fig. 6, it can be seen that the liquid outlet quantity of liquid reaches unanimity under basic, normal, high three gears.
In conclusion the structure etc. that quantitative liquid feedway of the invention imports head to medical fluid optimizes, together
When, medical fluid imports head and can be used in combination as bottle stopper or bottle cover with medicinal liquid bottle, can be realized cutaneous penetration, has and uses
The advantages of convenient, and cost is relatively low.In addition, quantitative liquid supply dress of the invention can also realize under vibrational state quantify to
Medicine is conducive to the absorptivity for improving medical fluid.
