Description

Technical Field

[0001] The invention relates to the technical field of oral cleaning devices, and in particular to a one-way liquid injection head and a mouthwash device for treating oral mucosal complications caused by radiotherapy. Background Art

[0002] Tumor radiotherapy is a local treatment method that uses radiation to treat tumors. The role and status of radiotherapy in tumor treatment are becoming increasingly prominent, and it has become one of the main means of treating malignant tumors. After radiotherapy for patients with head and neck tumors, the oral mucosa of the patient will change and be damaged. In mild cases, it will cause oral pain and discomfort, and in severe cases, it will cause difficulty in eating and decreased immunity. Oral mucosal damage can also cause systemic infection, leading to more serious complications, and oral ulcers are particularly prone to occur. Therefore, patients should pay special attention to oral hygiene after radiotherapy. Frequent gargling to remove oral food residues and bacteria is important for reducing the risk of infection, alleviating oral mucosal reactions, and promoting the healing of oral ulcers.

[0003] Especially for patients with head and neck tumors who need to rinse their mouths for a long time after radiotherapy, they need to use a cup to rinse their mouths again and again during the rinsing process, which is inconvenient to spit out water repeatedly. The Chinese patent with the publication (announcement) number CN214967002U discloses a rinsing device, including a bag body, a tube A, a connecting block, a tube B, and a mouthpiece; the bottom of the bag body is fixedly sleeved with a liquid outlet pipe, the connecting block is provided with a mouthpiece, one end of the tube A is connected to the liquid outlet pipe of the bag body, and the other end of the tube A is connected to the connecting block and is located in the inner cavity of the mouthpiece; the tube B is provided with a controller, one end of the tube B is connected to the connecting block and is located outside the mouthpiece. When rinsing the mouth, the patient draws the mouthwash from the bag body through the tube A, and at the same time, through the tube B, the controller and the negative pressure suction device, the mouthwash in the patient's mouth is discharged to the outside through the tube B under the action of the negative pressure suction device.

[0004] However, this technology still has the following problems: 1. It is necessary to find a place to hang the bag, which is inconvenient to use; 2. The mouthwash needs to be sucked in with the mouth, which is laborious to use and can easily cause discomfort to the patient's oral wound; 3. When the bag is hung high, the mouthwash is likely to flow out of the mouthpiece and cause choking, and if the bag is hung low, it will be difficult to suck in with the mouth and backflow; 4. Switching the mouthpiece during the process of sucking in and discharging the mouthwash is prone to water leakage; 5. Discharging the mouthwash is troublesome, and the structure is complex and the cost is high.

[0005] Therefore, a one-way injection head and a gargle device for oral mucosal complications caused by radiotherapy are proposed. Summary of the invention

[0068] The liquid collecting cover 30 is made by providing a front notch 32 on the nose-shielding portion of a general atomizing mask, and a through hole 34 is provided on the rear wall of the liquid collecting cover 30 . The lower end of the liquid collecting cover 30 is sealedly connected to the upper surface of the upper hole cover 20 .

[0069] The non-return socket cover 50 is a bottle cap with a valve connecting pipe 52 and a sealing sleeve 5 connected to the top surface and a flange pipe 51 connected to the upper end. A duckbill non-return valve 6 is inserted at the bottom of the valve connecting pipe 52.

[0072] The lower end of the hose 11 of the one-way liquid injection head 10 is plugged into the upper end of the Z-shaped tube 40 , and the inner convex ring 14 is stuck under the barb ring 41 .

[0073] In this embodiment, a wedge-tightening sealing ring 7 is provided under the top surface of the bottle cap; the Z-shaped tube 40 is made of polycarbonate plastic; the collecting bottle 1 and the washing liquid storage bottle 2 are both made of PET plastic; the inflatable ball 60 is a rugby-shaped hollow ball with a wall thickness of 3 mm and made of rubber with a hardness of 60 degrees.

[0074] The method of using the present invention is described in Figure 3 , Figure 4 :

[0075] S1, pour mouthwash into the washing liquid storage bottle 2 and tighten the non-return socket cover 50;

[0076] S2, the mouthwasher faces downward or keeps the mouthwash in the lotion storage bottle 2 without touching the bottle cap, holds the inflatable ball 60 (or someone else holds it), puts the one-way liquid injection head 10 into the mouth of the mouthwasher, and makes the lips fit with the hose 11 and the elastic wing 13;

[0077] S3, pinch the capsule body 61 and inject a proper amount of mouthwash into the mouth, then hold the one-way liquid injection head 10 in the mouth to rinse the mouth, or move the one-way liquid injection head 10 down into the mouth to rinse the mouth;

[0078] S4, after rinsing the mouth, the mouth holds the one-way liquid injection head 10 and directly spits out the mouthwash, or the mouth is close to the liquid collection cover 30 and spits the mouthwash into the liquid collection cover 30, and then one mouthwash is completed. Repeating the above S3 and S4 can perform multiple mouthwashes.

[0079] After the mouthwash is finished, the mouthwash collected in the collection bottle 1 is poured out and rinsed and can be reused.

[0080] The principle of the present invention for supplying mouthwash to the mouth of the mouthwasher is as follows:

[0081] When the bag body 61 is squeezed, its internal pressure increases, and the air in the bag body 61 passes through the duckbill one-way valve 6 on the valve tube 52 and is squeezed into the washing liquid storage bottle 2. Then the mouthwash in the washing liquid storage bottle 2 is pressed into the one-way injection head 10 through the Z-shaped tube, and then flows into the oral cavity from the upper end of the one-way injection head 10.

[0082] When the bladder body 61 is no longer squeezed, the duckbill one-way valve 6 at the upper end of the one-way injection head 10 and the duckbill one-way valve 6 on the valve connecting pipe 52 are both closed, and the outside air enters the bladder body 61 through the filter element 3 and the one-way valve sheet 6121, and the bladder body 61 rebounds, and the next squeezing can be performed.

[0083] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the embodiments here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
