Technical Field

[0001] This utility model belongs to the field of medical devices, and in particular relates to a mouth-held medicine dispensing device. Background Technology

[0002] Radiation therapy is a common cancer treatment that can effectively kill cancer cells, but it can also cause some damage to normal tissues. Among these side effects, mucosal damage is one of the most common side effects of radiation therapy, causing patients to experience discomfort such as oral ulcers and sore throats during treatment. These symptoms are usually relieved by using oral medications, such as chlorhexidine mouthwash, and patients also need to pay attention to oral hygiene and a healthy diet.

[0003] Currently, most devices for dispensing oral medications use cups with scales. To dispense the medication, the liquid is poured into the cup, and the appropriate amount is added according to the scale. The medication is then fed into the patient's mouth through the cup. This process needs to be repeated every time the medication is dispensed. The dispensing method is complicated and cumbersome, and the cup opening is too large, which can easily cause the medication to spill and stick to the patient's skin, clothes, or bed. Utility Model Content

[0004] The purpose of this invention is to provide a mouth-held medicine dispensing device that makes dispensing medicine simpler and faster, and reduces the risk of spillage.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example

[0015] The oral medication dispensing device described in this embodiment, such as Figure 1 , Figure 3 and Figure 5As shown, the device includes a horizontally positioned box 1, with a detachable sleeve 12 that communicates with the interior of the box 1 at its bottom. Different medicine bottles have different mouth diameters, therefore sleeves 12 with different inner diameters need to be prefabricated, allowing medical personnel to select the appropriate sleeve 12 based on the bottle diameter. The bottom of the box 1 has a through-hole that communicates with both the inside and outside; the upper end of the sleeve 12 is independently inserted into the through-hole, and the top of the sleeve 12 is fixed with several clips 11 for engaging with the bottom of the box 1. Figure 1 and Figure 3 As shown, in this embodiment, two buckles 11 are used, and the two buckles 11 are distributed symmetrically in a mirror image. When the upper end of the sleeve 12 moves into the perforation, the two buckles 11 are squeezed and bent inward. When the sleeve 12 is completely inserted into the perforation, the two buckles 11 return to their original shape through their own elasticity. The buckles 11 are engaged in the inner bottom of the box body 1 to prevent the sleeve 12 from moving outward and falling out. The sleeve 12 inserted into the perforation is fixed by the buckles 11. An installation groove is provided on the outer side wall of the sleeve 12 along the circumferential direction. A sealing ring 13 is engaged in the installation groove to seal the gap between the sleeve 12 and the wall of the perforation. After the upper end of the sleeve 12 is inserted into the perforation, the sealing ring 13 can seal the gap between the sleeve 12 and the wall of the perforation through its own elasticity, so as to prevent the oral medication from flowing out from the gap and causing waste of the oral medication. The inner wall of the sleeve 12 is provided with an internal thread that mates with the mouth of the medicine bottle. By fitting the sleeve 12 onto the mouth of the medicine bottle and rotating the sleeve 12, the sleeve 12 is fitted onto the mouth of the medicine bottle through the engagement between the internal thread of the sleeve 12 and the external thread of the mouth of the bottle, thereby connecting the medicine bottle to the inside of the box 1. The bottom of the box 1 is fitted with a storage tube 6 that communicates with the inside of the box 1. The bottom of the box 1 has a through hole that communicates with the inside and outside. The upper end of the storage tube 6 is fitted into the through hole, so that the storage tube 6 communicates with the inside of the box 1. The storage tube 6 is made of materials such as PS, PMMA, PP, and HDPE. The transparent material of the storage tube 6 allows medical staff to easily view the volume of the medicine inside the storage tube 6. The storage tube 6 is fitted with a piston 5 that can move up and down inside it. The piston 5 is made of materials such as brominated butyl rubber, chlorinated butyl rubber, silicone, and natural rubber. The piston 5 divides the storage tube 6 into upper and lower parts. The space inside the tube above the piston 5 is used to store oral medication. By moving the piston 5 up and down, the size of the space inside the tube above the piston 5 can be adjusted. The outer wall of the storage tube 6 is provided with a scale for checking the amount of medicine. In use, by aligning the top of the piston 5 with the scale strips at different positions, the size of the space inside the tube above the piston 5 can be changed more precisely, thereby adjusting the amount of medicine stored in the storage tube 6. The box body 1 has a through hole that connects the inside and outside. A one-way valve 2 is installed in the through hole to prevent the medicine from flowing out. The one-way valve 2 is a commonly used one-way valve, such as the CJT012 model one-way valve. The one-way valve 2 can prevent the oral medicine in the box body 1 from flowing out to the outside through the through hole, while the outside air can enter the box body 1 through the one-way valve 2. This allows enough air to enter the box body 1 when the patient inhales the oral medicine, so that the oral medicine can flow into the patient's mouth more easily. A pull tube 7 is vertically inserted through the piston 5, communicating with the upper space of the storage tube 6. The piston 5 has an insertion hole that communicates with the upper and lower parts. The upper end of the pull tube 7 is inserted into the insertion hole, and the lower end of the pull tube 7 is located outside the storage tube 6. In use, the pull tube 7 connects to the space inside the tube above the piston 5, and the liquid medicine in the mouth of the storage tube 6 can be discharged through the pull tube 7. By pushing and pulling the pull tube 7 up and down, the piston 5 can be moved up and down inside the storage tube 6. The bottom of the storage tube 6 is detachably fitted with a cover 8 to prevent the piston 5 from dislodging, such as... Figure 1 As shown, the inner wall of the cover 8 is provided with an internal thread, and the lower end of the storage tube 6 is provided with an external thread that is threadedly engaged with the internal thread; after the cover 8 is fitted onto the lower end of the storage tube 6, it can cover the lower end of the storage tube 6 to prevent the piston 5 from coming out of the lower end of the storage tube 6. The cover 8 is provided with a hole for the pull tube 7 to pass through. A pull plate 9 is fitted on the lower end of the pull tube 7. The pull plate 9 is located at the lower end of the pull tube 7, and the pull plate 9 makes it convenient for medical staff to pull the pull tube 7. A valve 4 is installed inside the pull tube 7 to block the liquid medicine, such as... Figure 1 As shown, in this embodiment, valve 4 is a cross-cut silicone valve. The silicone valve consists of an arc-shaped silicone cap and a cross-shaped cut on the silicone cap. The elasticity of the silicone valve itself seals the pull tube 7 to prevent leakage, thus preventing the liquid from flowing into the straw 10. This allows for more accurate confirmation of the amount of liquid in the tube above the piston 5. When the liquid needs to be fed into the patient's mouth, the patient opens the silicone valve by suction from their mouth, allowing the liquid to flow out from the pull tube 7. Cross-cut silicone valves are used in existing products, such as on beverage bottle caps. Valve 4 can also be a YJ-01 or XFSV model valve. The lower end of the pull tube 7 is connected to a straw 10 that communicates with it. The straw 10 is made of soft materials such as polypropylene, polyethylene, and silicone. The soft straw 10 can be bent in different directions so that patients can suck the oral liquid in different positions and avoid spilling the liquid. The box body 1 is fixed with a clip 3 for securing the straw 10; such as Figure 1 box Figure 2As shown, the clip 3 is fixed on the right side wall of the box 1. The clip 3 has a "U" shaped structure. When the straw 10 is not in use, the unfixed end of the straw 10 can be locked in the clip 3. The clip 3 fixes the unfixed end of the straw 10 to prevent it from moving around and getting dirty.

[0016] In actual use, medical staff use the corresponding sleeve 12 according to the diameter of the medicine bottle. The upper end of the sleeve 12 is inserted into the perforation, and the sleeve 12 is installed on the box body 1 using the buckle 11. Then, the sleeve 12 is fitted onto the mouth of the medicine bottle and secured with threads, thus connecting the medicine bottle to the inside of the box body 1. Medical staff pull down the pull tube 7 according to the patient's required dosage. The pull tube 7 moves the piston 5 down along the storage tube 6, aligning the top of the piston 5 with the corresponding graduation mark to determine the amount of medicine stored in the storage tube 6. Then, the medicine bottle and the device are rotated 90 degrees towards the storage tube 6, allowing the medicine in the bottle to flow along the box body 1 into the storage tube 6. The medicine is then circulated through the space inside the storage tube 6 above the piston 5. After the storage tube 6 is filled with the medicine, the medicine bottle and the device are reversed to allow the medicine overflowing the top of the storage tube 6 to flow back into the medicine bottle, so that the storage tube 6 is filled with the required amount of medicine. Then, the medical staff puts one end of the straw 10 into the patient's mouth, and the patient sucks the medicine in the storage tube 6 through the straw 10. When the valve 4 senses the suction, the valve 4 opens, allowing the medicine in the storage tube 6 to be transferred to the patient's mouth through the straw 10. During the transfer of the medicine, outside air will enter the box 1 through the one-way valve 2 to replenish the air in the box 1. After adjusting the piston 5 once to determine the amount of medicine, if the amount does not need to be changed in subsequent uses, the device can be directly flipped to fill the medicine, making the dispensing method simpler and faster.
