Description

Oral low-temperature flusher for reducing oral mucositis during chemotherapy

Technical Field

The invention belongs to the technical field of oral cavity flushing, and particularly relates to an oral cavity low-temperature flusher for reducing oral mucositis during chemotherapy.

Background

Oral mucositis is one of the most common complications in the treatment process of anti-tumor drug, radiotherapy and hematopoietic stem cell transplantation of cancer patients, and is mainly manifested by uncomfortable symptoms such as inflammatory changes, dryness, sensitivity, pain, ulcer and the like of the oral mucosa at different degrees. The oral mucositis caused by anti-tumor treatment can be prevented by applying conventional oral care, but the workload of nurses is increased due to complex procedures and long-term adherence, and the patient management flow is complicated, the compliance is not high, and the prevention effect is often poor. In addition, patients can take ice cubes or ice water before, during and after rapid infusion of chemotherapy drugs with short half-lives in large doses to prevent oral mucositis, but the curative effect is not very exact, and the self-body of the patients is poor.

The patent of US10478267B2 relates to an oral irrigator having separate high pressure water and low pressure rinse systems for delivering two different liquids to a pick or other accessory. The water system and the rinse system are combined in one handle. The pick is connected to the handle. The water system has a block valve on the handle and the rinse system has a hand pump on the handle. The manual pump is located beside the valve button closing the blocking valve. When the manual pump is pressed, the manual pump can press a valve button of the blocking valve to cut off the source of the high-pressure water to the water nozzle. The pressure in the pick is reduced so that the hand pump can introduce mouthwash into the pick. When the hand pump is released, the blocking valve opens and high pressure water returns to the pick.

Most existing oral irrigators are located for home use, for example, the application of the invention published under the number US20190358006A1, do not have medical functions, and have low medical feasibility. However, the medical oral irrigator is still immature, and the existing oral irrigator for auxiliary medical treatment often has the defects of complex operation, poor patient experience and the like.

The auxiliary plate 34 can be moved and positioned inside the first base body 10, so that wearing comfort of the flusher can be improved as much as possible, and the heat exchange range of the cooling tube set 11 to the inside of the mouth cavity can be enlarged by the movable auxiliary plate 34.

By dividing the auxiliary assembly 30 into two symmetrical parts, and having a certain interval between the two auxiliary plates 34, and connecting the two auxiliary plates by the elastic member 36 and the rotating rod 35 in the middle, the gap between the auxiliary plates 34 can be enlarged by the movement of the tongue during spraying, which is helpful for the flow and discharge of the flushing liquid. By designing the elastic member 36 and the auxiliary plates 34, etc., the entry of the blocks or other dirt inside the oral cavity into the auxiliary passage 31 is facilitated when the gap between the two auxiliary plates 34 is enlarged, so that the cleaning effect is improved.

By providing the auxiliary plate 34 and the elastic member 36, the auxiliary plate 34 has a certain up-down movement range, so that the movement space of the tongue is released, and the auxiliary plate is used by people with different tongue sizes, thereby improving the comfort level. The auxiliary plate 34 is arranged to contact the surface of the tongue and even contact the palate of the oral cavity, so that excessive shaking of the first matrix 10 in the oral cavity can be avoided, further, the aggravation of friction contact between the first matrix 10 and teeth and the skin of the inner wall of the oral cavity can be avoided, and the protection of the oral cavity can be enhanced.

Example 3

Fig. 10 schematically shows an oral cryoirrigator for reducing oral mucositis during chemotherapy according to another embodiment of the present invention, which differs from example 1 in that:

the cooling pipe group 11 is connected with the control box through the first connecting pipe body 62, the control box is used for providing cooling liquid to the cooling pipe group 11, the compressor 63 is arranged in the control box, the compressor 63 is matched with the refrigerant and used for cooling the local environment in the control box, so that the cooling liquid flowing through the control box can be refrigerated, and the cooling liquid entering the oral cavity is guaranteed to be in a low-temperature state. The spray tube set 14 may be connected to a control box via a second connecting pipe (not shown) and a flushing liquid may be supplied into the spray tube set 14 via the control box. The first connecting pipe 62 and the second connecting pipe are matched with a valve body (not shown in the figure), so that the flowing states of the cooling liquid and the flushing liquid can be regulated and controlled.

Two substrates 61 are arranged in the control box, and a gap is arranged between the two substrates 61; a plurality of heat radiating fins 64 are arranged above the two base plates 61 in parallel, the first connecting pipe body 62 is matched with the heat radiating fins 64, and a heat radiating fan 65 is arranged on the side of the plurality of heat radiating fins 64.

So, have the clearance between two base plates 61 that set up, radiator fan 65 exhaust direction is not only limited to radiator fin 64 one side, can also exchange heat through the mode to bottom exhaust air current, has increased the heat transfer area like this, and then avoids the heat concentration of control box single position, effectively improves ambient temperature's equilibrium. In addition, the expansion of the heat exchange area can reduce the airflow discharge flow of a single position, thereby reducing wind noise.

Conventional operations in the operation steps of the present invention are well known to those skilled in the art, and are not described herein.

While the foregoing embodiments have been described in detail in connection with the embodiments of the invention, it should be understood that the foregoing embodiments are merely illustrative of the invention and are not intended to limit the invention, and any modifications, additions, substitutions and the like made within the principles of the invention are intended to be included within the scope of the invention.
