Flange is compound in lamellar sticker lower surface by medical adhesive.The medicinal liquid of seal groove bottom land can flow at injury by drain hole,
And the ring threaded line of side can stop that outside the medicinal liquid flow direction of discharge, discharge opeing performance is good.
Specifically, blind flange and flange are rounded, and the external diameter of blind flange is more than the external diameter of flange;Have outside blind flange
Beyond the flange portion of flange, it is easy to during dosing push aside blind flange.
A kind of beneficial effect of lid formula drug of topical application patch of the present utility model is:
1. blind flange passes through card bulb and seal groove cooperation clamping, good airproof performance;Seal groove and sealing drum enable triple
Stop, prevent medicinal liquid from flowing out;Do not need to remove drug of topical application patch and can add the drug of topical application, can be implemented using different plus drug of topical application modes, add prescription
Just;One course for the treatment of can use a drug of topical application patch of the present utility model with repetitive cycling, do not result in waste, alleviate the warp of patient
Ji burden;Additionally, taking the drug of topical application to paste without tearing, the misery of patient will not be increased, beneficial to the recovery from illness of injury;
2. the flange seal face of flange is provided with ring threaded line, is favorably improved sealing;
3. the medicinal liquid of seal groove bottom land can be flowed at injury by drain hole, and the ring threaded line of side can stop discharge
Outside medicinal liquid flow direction, discharge opeing performance is good;
4. blind flange and flange are rounded, and the external diameter of blind flange is more than the external diameter of flange;Have outside blind flange and exceed
The flange portion of flange, is easy to during dosing push aside blind flange.

Specific embodiment
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification,
Basic structure of the present utility model is only described in a schematic way, therefore it only shows the composition relevant with this utility model.
The specific embodiment of of the present utility model a kind of lid formula drug of topical application patch as Figure 1-Figure 4, it includes lamellar sticker
1st, flange 2 and blind flange 3, flange 2 socket joint is higher than the upper surface of lamellar sticker 1 in lamellar sticker 1 central authorities, the cervical part of esophagus of flange 2, method
Blue 2 lip fits ring on the lower surface of lamellar sticker 1, the cervical part of esophagus end face of flange 2 is provided with seal groove 4, and the two of seal groove 4
Side channel wall is in wavy and is symmetrical arranged;The lower surface of blind flange 3 is fixed with the sealing drum 5 in seal groove 4, sealing drum 5
It is fixed with card bulb 6 away from ring on one end of blind flange 3, blind flange 3 passes through card bulb 6 and coordinates clamping with seal groove 4;Flange
It is filled with medical cushion 7 in 2;Flange 2 passes through medical adhesive and lamellar sticker 1 palette, and the lower surface of lamellar sticker 1 is combined
There is medical adhesive layer.
Flange 2 and blind flange 3 can be flexible medical grade rubber, be easy to the local buckling on skin.When needing dosing,
Only need to slowly extract blind flange 3, the dosing toward on medical cushion 7, finally again blind flange 3 is joined with seal groove 4 by card bulb 6
Close clamping, good airproof performance;Seal groove 4 and sealing drum 5 enable triple stops, prevent medicinal liquid from flowing out;Do not need to remove drug of topical application patch
The drug of topical application can be added, can be implemented using different plus drug of topical application mode, add prescription just.One course for the treatment of can use this reality with repetitive cycling
Apply the drug of topical application patch of example, do not result in waste, alleviate the financial burden of patient;Additionally, taking the drug of topical application to paste without tearing, disease will not be increased
The misery of people, beneficial to the recovery from illness of injury.
Specifically, the flange seal face of flange 2 is provided with ring threaded line 8, is favorably improved sealing.
Preferably, the surface roughness in the flange seal face of flange 2 is ra6.3, and sealing property is more preferable.
Specifically, the bottom land ring of seal groove 4 is evenly equipped with some drain holes 9, and each drain hole 9 each leads to the sealing surface of flange 2;Method
Blue 2 flange is compound in lamellar sticker 1 lower surface by medical adhesive.The medicinal liquid of seal groove 4 bottom land can be flowed into by drain hole 9
At injury, and the ring threaded line 8 of side can stop that outside the medicinal liquid flow direction of discharge, discharge opeing performance is good.
Specifically, blind flange 3 and flange 2 are rounded, and the external diameter of blind flange 3 is more than the external diameter of flange 2;I.e. outside blind flange 3
Side has the flange portion beyond flange 2, is easy to during dosing push blind flange 3 aside.
It should be appreciated that specific embodiment described above is only used for explaining this utility model, it is not used to limit this reality
With new.The obvious change extended out by spirit of the present utility model or variation are still in protection of the present utility model
