Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1
[0029] like Figure 1-2 As shown, an oral mucosal wet dressing drug delivery device includes a housing 1, a tongue depressor 2, a drug storage cup 6, an oral fixation component, and a drug delivery component.
[0030] The housing 1 is L-shaped, with a tongue depressor 2 located at one end and detachably fitted with a sponge sleeve 5. The tongue depressor 2 has an infusion chamber 3, and several infusion holes 4 are evenly distributed on the surface of the tongue depressor 2 that contacts the sponge sleeve 5. These infusion holes 4 communicate with the infusion chamber 3. Both the tongue depressor 2 and the infusion chamber 3 have U-shaped cross-sections. The dimensions of the infusion chamber 3 can be determined according to actual needs. A medicine storage cup 6 is located at the other end of the housing 1 and is threadedly connected to it. To improve sealing, a sealing ring can be installed between the medicine storage cup 6 and the housing 1. The medicine storage cup 6 is made of transparent plastic and has capacity markings on its outer side.
[0031] The oral fixation assembly includes a fixation airbag 7 and an inflation device 8 for inflating the fixation airbag 7. The fixation airbag 7 is mounted on the tongue depressor 2 and located between the sponge sleeve 5 and the housing 1. The inflation device 8 is connected to the housing 1 and to the fixation airbag 7 via an inflation tube 27. The inflation tube 27 is connected to a deflation valve 28 via a branch tube.
[0032] Specifically, the inflation device 8 includes a first latex ball 9, a first pressing plate 10, a first drive rod 11, and a first pressing head 12. The first latex ball 9 is fixedly installed inside the housing 1 and connected to a first one-way air inlet valve and a first one-way air outlet valve. The first one-way air outlet valve is connected to the inflation tube 27. The first pressing plate 10 is connected to the first latex ball 9. One end of the first drive rod 11 is connected to the first pressing plate 10, and the other end extends movably through the housing 1 and is connected to the first pressing head 12. A first return spring is sleeved on the first drive rod 11. The first return spring is located between the housing 1 and the first pressing head 12 and is used to drive the first pressing head 12 to return to its original position. The vent valve 28 is located on the outside of the housing 1, and the housing 1 has several air inlets 20 communicating with its internal cavity.
[0033] When inflation is required, press the first pressing head 12. The first pressing head 12 drives the first pressing plate 10 to move towards the first latex ball 9 via the first drive rod 11. The first pressing plate 10 squeezes the first latex ball 9, and the gas inside the first latex ball 9 enters the fixed air bag 7 through the inflation tube 27, thereby causing the fixed air bag 7 to inflate. Due to the setting of the first one-way air outlet valve, the air entering the fixed air bag 7 will not flow back into the first latex ball 9. Due to the setting of the first one-way air inlet valve, the first latex ball 9 can automatically restore its shape after air intake for the next inflation. When it is necessary to deflate the fixed air bag 7, simply open the deflation valve 28.
[0034] This invention involves attaching a medication-permeable sponge sleeve 5 to a tongue depressor 2, and a fixing air bladder 7 to the tongue depressor 2. By inflating the fixing air bladder 7, it presses against the upper and lower teeth, thus fixing the tongue depressor 2 and sponge sleeve 5 in the patient's mouth. This eliminates the need for the patient to forcefully press the medication application structure with their hands; the patient only needs to hold the medication bottle, providing convenience and improving medication adherence. The fixing air bladder 7 on the tongue depressor 2 can also help the patient open their mouth, thereby promoting mouth-opening exercises and regulating the oral flora.
[0035] The medicine delivery assembly includes a delivery tube 13 and a pressurizing device 15. One end of the delivery tube 13 is located at the bottom of the inner cavity of the medicine storage cup, and the other end passes through the inner cavity of the housing 1 and is connected to the infusion chamber 3 of the tongue depressor 2. A one-way infusion valve 14 is provided on the delivery tube 13 to prevent backflow of the medicine. The pressurizing device 15 is connected to the housing 1, and its vent is connected to the upper part of the inner cavity of the medicine storage cup. By pressurizing the inner cavity of the medicine storage cup through the pressurizing device 15, the medicine can be forced into the delivery tube 13 for delivery.
[0036] Specifically, the pressurizing device 15 includes a second latex ball 16, a second pressing plate 17, a second drive rod 18, and a second pressing head 19. The second latex ball 16 is fixedly installed inside the housing 1 and is connected to a second one-way air inlet valve and a second one-way air outlet valve. The second one-way air outlet valve is connected to the upper part of the inner cavity of the medicine storage cup through a pressurizing pipe 26. The second pressing plate 17 is connected to the second latex ball 16. One end of the second drive rod 18 is connected to the second pressing plate 17, and the other end extends movably out of the housing 1 and is connected to the second pressing head 19. A second return spring is sleeved on the second drive rod 18, and the second return spring is located between the housing 1 and the second pressing head 19. The second return spring is used to drive the second pressing head 19 to return to its original position.
[0037] When medication administration is required, the second pressing head 19 is pressed. The second pressing head 19, via the second drive rod 18, drives the second pressing plate 17 to move towards the second latex ball 16. The second pressing plate 17 squeezes the second latex ball 16, and the gas inside the second latex ball 16 enters the inner cavity of the medicine cup through the pressurization tube 26, increasing the air pressure inside the medicine cup. This forces the medicine in the medicine cup 6 into the infusion tube 13, and then delivers it to the infusion chamber 3 of the tongue depressor 2. Finally, it flows out through several infusion holes 4 to the sponge sleeve 5, and then permeates to the oral wound. Due to the second one-way air valve, the air entering the inner cavity of the medicine cup will not flow back into the second latex ball 16. Due to the second one-way air inlet valve, the second latex ball 16 can automatically return to its original shape after air intake for the next squeezing.
[0038] This invention uses a pressurizing device 15 to squeeze and deliver the liquid medicine in the medicine storage bottle to the infusion chamber 3 of the tongue depressor 2, and then delivers it to the sponge sleeve 5 through several evenly distributed infusion holes 4, thereby allowing the liquid medicine to penetrate into the wound. Compared with the existing technology of squeezing the elastic bottle to deliver the liquid medicine, this invention is simpler to operate and has higher accuracy in dosage.

An atomizing connector 21 is provided at the bottom of the drug storage cup 6, and a one-way delivery valve 22 is provided on the atomizing connector 21 to prevent liquid or gas leakage. The atomizing connector 21 is connected to the atomizing host through the atomizing connecting tube 23. One end of the atomizing delivery tube 24 passes through the housing 1 and connects to the top of the inner cavity of the atomizing cup, while the other end passes through the center of the end of the tongue depressor 2 furthest from the housing 1 and is flush with the surface of the tongue depressor 2. An on / off control valve 25 is provided on the atomizing delivery tube 24. The on / off control valve 25 is a manual valve, and its operating end extends to the outside of the housing 1. When drug administration is required, the on / off control valve 25 should be closed; when nebulization therapy is required, the on / off control valve 25 should be opened.
[0041] In addition, this utility model also includes a nebulizer component, which can perform nebulization therapy and oral oxygen therapy, integrating multiple functions into one.
