Description

Technical Field

[0001] The present invention relates to the technical field of oral mucosa treatment devices, and particularly to an oral mucosa local drug application and bite prevention device. Background Art

[0002] The oral mucosa refers to the tissue covering the oral surface, which is composed of an epithelial layer, a lamina propria, and a submucosa. It functions to line, moisten, chew, and distinguish taste. The epithelium of the oral mucosa is equivalent to the epidermis of the skin, but only the mucosal epithelium in the gingiva and hard palate areas is keratinized, and the mucosal tissues in the remaining areas are relatively loose, and the overall is more fragile than the skin tissue. Common oral mucosal lesions include ulcers, erosions, blisters, epithelial hyperkeratosis, epithelial dysplasia, etc. When the above-mentioned lesions occur in the oral mucosa, local treatment of the oral mucosa is required. In the prior art, medicaments such as mouthwashes, sprays, aerosols, lozenges, and ulcer patches are usually used for local treatment of mucosal lesions. The action time of the medicaments on the lesion area is short. If the use frequency of the above-mentioned medicaments is increased, the risk of swallowing the medicine and entering the systemic circulation is increased.

[0003] The present invention is particularly suitable for children. After mucosal lesions occur in children, they often make behaviors such as repeatedly rubbing, sucking, or biting the mucosa with their teeth due to local burning pain, itching and other discomforts, which cause the lesions to not heal or continue to worsen. The buccal and tongue screens of the present invention can isolate the teeth from the mucosa and block the aggravation of artificial mechanical stimulation on the lesions; for young children, the present invention is relatively easier to obtain the cooperation of the children compared to traditional drug delivery methods such as mouthwashes and sprays.

A cut-off mechanism is provided on the storage box 2 for cutting off the spraying of the medicine at one end of the medicine delivery tube 22.

[0025] Among them, the driving mechanism includes a sealed air cavity 71 opened in the jaw pad 7. One end of the jaw pad 7 is fixedly connected to a tongue pushing medicine film 72. The material of the tongue pushing medicine film 72 is silica gel, which is an organosilicon compound and has good flexibility and elasticity. Therefore, the silica gel film can undergo a certain deformation when subjected to an external force and has elasticity. An air inlet hole 11 for communicating the inside of the sealed air cavity 71 and the medicine storage tank 3 is provided on the cheek and tongue screen 1. The function of the air inlet hole 11 is to regulate the gas flow, and by changing the gas flow speed and direction, a pressure difference is generated between the sealed air cavity 71 and the medicine storage tank 3.

[0026] Secondly, the cut-off mechanism includes a support seat 8 connected to the storage box 2. A chute 81 is opened inside the support seat 8. A pair of cut-off sliders 82 for clamping the medicine delivery tube 22 are slidably connected inside the chute 81. A hand-held medicine application block 83 is provided on the chute 81. The function of the hand-held medicine application block 83 is to facilitate the movement of one end of the medicine delivery tube 22, so that the medicine delivery tube 22 can drive the medicine application head 85 to move to the wound position. The hand-held medicine application block 83 is fixedly sleeved with one end of the medicine delivery tube 22. A clamping block 84 is fixedly connected to the lower surface of the hand-held medicine application block 83 for clamping the pair of cut-off sliders 82 to clamp the medicine delivery tube 22 after being inserted between the chute 81 and the cut-off sliders 82.

[0027] Furthermore, the connecting mechanism includes a rack belt 51 connected to one end of the long binding strap 5. A plurality of V-shaped grooves 52 arranged linearly on the long binding strap 5 are formed on the rack belt 51. The function of the V-shaped grooves 52 is to enable the rotating latch 62 to be inserted into different V-shaped grooves 52 according to the size of the patient's head, and finally achieve fixation. One end of the short binding strap 4 is fixedly connected with a socket 6 for inserting the rack belt 51. A return spring 64 for pushing the other end of the rotating latch 62 back to its original position is fixedly connected to the socket 6. The function of the return spring 64 is to enable the rotating latch 62 to be always inserted into the V-shaped groove 52 on the rack belt 51 under normal conditions. A rotating groove 63 is formed on the socket 6. A rotating support block 61 is fixedly connected to the socket 6. The rotating support block 61 is rotatably connected with a rotating latch 62. One end of the rotating latch 62 movably penetrates through the rotating groove 63 and is used for inserting into the V-shaped groove 52 inserted into the socket 6.

[0028] In this embodiment, when the local drug application and bite prevention device for oral mucosa is needed, as Figure 3 shown, the liquid medicine is sent into the interior of the medicine storage tank 3 through the spiral medicine pouring tube 31 on the medicine storage tank 3. As Figure 1 shown, the buccal screen 1 is placed between the upper and lower dental arches and the lips, and the tongue screen is placed between the dental arches and the tongue. At the same time, the jaw pad 7 is inserted into the patient's oral cavity and bitten between the upper and lower teeth, so that the teeth can be isolated from the lip and tongue mucosa in three dimensions to prevent the teeth from biting the oral mucosa. Then, the connecting mechanism is used to bind the head, and the buccal and tongue screens 1 and the jaw pad 7 can be fixed in the mouth to avoid falling off. As Figure 2 shown, pull the handheld medicine application block 83 to drive the top end of the medicine delivery tube 22 towards the wound of the patient's oral mucosa, so that the medicine application head 85 abuts against the wound. Then, as Figure 4 shown, at this time, use the tongue to press against the tongue pushing medicine film 72 inside one end of the jaw pad 7. After pressing, the tongue pushing medicine film 72 is recessed into the sealed air cavity 71. Through the pressure difference, use the tongue to repeatedly press against the tongue pushing medicine film 72 into the sealed air cavity 71. At this time, the liquid medicine in the medicine storage tank 3 will flow through the connecting hole 33 at the bottom of the medicine storage tank 3 to the connecting tube 24. As Figure 5 shown, at this time, the liquid medicine is conveyed to the medicine application head 85 at the other end of the medicine delivery tube 22 through one end of the medicine delivery tube 22, so that the liquid medicine can be sprayed on the wound, which is simple and easy to operate.

[0029] When the medicine delivery mechanism is used up, as Figure 2 and Figure 5 shown, only need to rotate the knob 21 to drive the winding and storage rod 23 to rotate. The winding and storage rod 23 drives the snap ring 25 to rotate, and the snap ring 25 will drive the middle part of the medicine delivery tube 22 to wind around the winding and storage rod 23, so that the medicine delivery tube 22 can be stored inside the tube storage box 2. As Figure 6As shown in the figure, at this time, it is only necessary to move the hand-held medicine application block 83 so that the pair of clamping blocks 84 on the lower surface of the hand-held medicine application block 84 are clamped between the sliding groove 81 and the flow intercepting slider 82. At this time, the pair of flow intercepting sliders 82 are pushed by the clamping blocks 84 and will slide along the sliding groove 81 in the direction of the medicine delivery pipe 22 until the clamping blocks 84 are completely inserted into the sliding groove 81. At this time, the relative ends of the pair of flow intercepting sliders 82 can clamp the medicine delivery pipe 22, so that the liquid medicine cannot be delivered to the medicine application head 85 through the medicine delivery pipe 22; When it is necessary to open the connection mechanism tied to the head, such as Figure 7 and Figure 8 As shown, press the end of the rotating lever 62 away from the rotating groove 63 in the direction of the ferrule 6. The rotating lever 62 rotates around one end of the rotating support block 61. At the same time, the other end of the rotating lever 62 slides along the rotating groove 63 and then disengages from the V-shaped groove 52 on the rack belt 51, so that the rack belt 51 at one end of the long binding belt 5 can be quickly withdrawn from the ferrule 6. Then, the buccal and lingual screens 1 and the jaw pad 7 can be taken out of the patient's oral cavity, which is simple and easy to operate.
