Description

Technical Field

[0001] This utility model belongs to the field of medical device technology and relates to a rinsing and suction oral irrigator. Background Technology

[0002] Most critically ill patients experience varying degrees of swallowing difficulties, often exhibiting impaired swallowing and cough reflexes. Vomit and other secretions may remain between the teeth, and the mouth remains open for extended periods, leading to dry oral mucosa, reduced saliva production, and excessive bacterial growth. Furthermore, many critically ill patients with swallowing difficulties or tracheotomies are unable to perform oral eating, drinking, brushing, or rinsing, resulting in decreased oral hygiene. They often also suffer from complications such as malnutrition and lung infections, weakening their immune system. The extensive use of antibiotics can disrupt the gut microbiota, creating ideal conditions for rapid bacterial growth. This not only reduces oral hygiene but can also lead to severe aspiration pneumonia due to the aspiration of large amounts of bacteria from the mouth. Therefore, oral care is crucial for critically ill patients and those with swallowing difficulties.

[0003] Currently, oral irrigation and hygiene care for patients typically rely on instruments. Besides commonly used cotton swabs, gauze, and syringes, a new type of oral irrigator, the controllable irrigation-suction type, has emerged. For example, a disposable controllable irrigation-suction type oral suction device (application number: 201620310405.X) disclosed in patent literature includes a handle with an internal suction chamber. A negative pressure port is located on the upper side of the handle and communicates with the suction chamber. A water inlet is located at the front end of the handle, and an external connector is located at the rear end. The suction chamber connects the water inlet to the external connector. A cleaning head is located around the water inlet. However, this disposable controllable irrigation-suction type oral suction device has the following shortcomings in practical use:

[0004] In the intensive care unit, patients need to use oral irrigators for a long time. These are usually purchased and used continuously by the patient's family. If they are used once and then thrown away, the cost is very high. If the irrigator is reused for a long time, the brush head will be difficult to clean, and the cleaning ability of the bristles will decrease after repeated use. Currently, the solution to this problem is to replace the entire rinsing and suction oral irrigator, which leads to high operating costs. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a flushing-suction type oral irrigator. This invention solves the problem that existing flushing-suction type oral irrigators are difficult to replace individually, resulting in high usage costs.

[0006] The objective of this utility model can be achieved through the following technical solution: A rinsing-suction oral irrigator includes a brush handle with an internal suction channel and a brush head with an internal suction chamber. The brush head has a water suction hole penetrating its inner and outer walls, and the surface of the brush head is provided with bristles. A negative pressure connector is connected to the rear end of the brush handle. A rinsing hose is provided inside the brush handle. One end of the rinsing hose extends from the negative pressure connector and is connected to a syringe connector. A pressing hole communicating with the suction channel is opened on the outer wall of the brush handle. The brush handle has a cylindrical insertion section with a reduced outer diameter at the front end. The brush head has an insertion hole communicating with the suction chamber at the rear end. The insertion section is inserted into the insertion hole. A water spray pipe is fixedly connected to the outer wall of the rear end of the brush head. The front end of the water spray pipe is facing the bristles. A cylindrical hose connector is fixedly connected to the outer wall of the front end of the brush handle. The other end of the rinsing hose extends out of the brush handle and is fixedly connected to the hose connector. The rear end of the water spray pipe is inserted into the hose connector, so that the rinsing hose is connected to the water spray pipe.

[0007] In use, the negative pressure connector is connected to the negative pressure suction device. After the syringe is filled with cleaning solution, the syringe is connected to the syringe connector. Then, the operator holds the brush handle with one hand and operates the syringe with the other. The water from the syringe flows through the rinsing hose to the spray pipe, and then sprays out onto the brush bristles, wetting them to clean the patient's mouth. When it is necessary to suction out the cleaning solution from the patient's mouth, the pressure hole is blocked with a finger. At this time, under the negative pressure suction of the negative pressure suction device, the cleaning solution in the patient's mouth flows out sequentially through the suction hole, suction chamber, suction channel, and negative pressure connector.

[0008] In this rinsing-suction oral irrigator, the brush handle has a cylindrical connector with a reduced outer diameter at the front end, while the brush head has a connector hole at the rear end that connects to the suction chamber. This allows for easy replacement of the brush head; simply remove the old brush head, insert the connector of the brush handle into the connector hole of the new brush head, and simultaneously connect the hose to the water spray hose. Clearly, after a period of use, when the brush head's cleaning ability declines, only the brush head needs to be replaced, rather than the entire rinsing-suction oral irrigator, thus reducing operating costs.

[0009] In the aforementioned rinsing-suction oral irrigator, the brush head includes a main body and a rubber sleeve fitted over the main body. The bristles are integrally formed on the outer wall of the rubber sleeve, and the rear end of the main body forms an insertion hole. This design allows the bristles to be soft, while the main body can be made of hard plastic, facilitating insertion with the brush handle and ensuring insertion stability.

[0010] In the aforementioned rinsing-suction oral irrigator, the other end of the rinsing hose extends into the hose connector and is fixedly connected to the hose connector. The fixed connection can be achieved by adhesive bonding or heat fusion bonding, etc.

[0011] In the aforementioned rinsing-suction oral irrigator, the rear end of the brush handle has a connector, into which the negative pressure connector is inserted. This design allows for convenient assembly during manufacturing. The rinsing hose is first inserted into the brush handle from the front end, with the end of the hose near the negative pressure connector extending from the connector. Then, the rinsing hose is passed through the through-hole of the negative pressure connector, and the connector is finally inserted into the connector for fixation.

[0012] In the aforementioned rinsing-suction oral irrigator, the outer wall of the rubber sleeve is provided with a flexible strip that covers the front end of the water spray tube. This design prevents the end of the water spray tube from contacting the mouth, making the rinsing-suction oral irrigator more comfortable to use.

[0013] In the aforementioned rinsing and suction oral irrigator, the flexible strip is made of rubber material, the middle part of the flexible strip covers the front end of the water spray pipe, and the two ends of the flexible strip are fixedly connected to the rubber sleeve.

[0014] In the aforementioned rinsing-suction oral irrigator, the outer peripheral wall of the insertion segment abuts against the inner wall of the insertion hole. Both the brush head body and handle are made of plastic. Therefore, during the insertion process, slight deformation of the plastic material allows the outer peripheral wall of the insertion segment to abut against the inner wall of the insertion hole after insertion, thus improving the stability of the insertion.

[0015] Compared with existing technologies, this flushing-suction oral irrigator has the following advantages:

[0016] 1. After a period of use, when the cleaning ability of the brush head of this rinsing-suction oral irrigator decreases, the brush head can be replaced separately instead of the entire rinsing-suction oral irrigator, thus reducing the cost of use.

[0017] 2. Compared to some existing oral irrigators on the market that require separate replacement of the bristle-covered rubber sleeve, which is difficult and troublesome to replace due to the soft material of the sleeve and the need for a tight fit on the brush head for a stable connection, this oral irrigator features a convenient and effortless connection between the brush head and handle, thus offering the advantage of easy brush head replacement.

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figures 1 to 4 As shown, this rinsing-suction oral irrigator includes a brush handle 1 with an internal suction channel 11 and a brush head 2 with an internal suction chamber 21. The brush head 2 has a water suction hole 22 penetrating its inner and outer walls, and bristles 231 are provided on the surface of the brush head 2. A negative pressure connector 3 is connected to the rear end of the brush handle 1. A rinsing hose 4 is provided inside the brush handle 1. One end of the rinsing hose 4 extends from the negative pressure connector 3 and is connected to a syringe connector 5. A pressing hole 12 communicating with the suction channel 11 is opened on the outer wall of the brush handle 1. The brush handle 1 has an outer diameter of... The reduced cylindrical insertion section 13 has a insertion hole 241 at the rear end of the brush head 2 that communicates with the suction chamber 21. The insertion section 13 is inserted into the insertion hole 241. A water spray pipe 6 is fixedly connected to the outer wall of the rear end of the brush head 2. The front end of the water spray pipe 6 is directly opposite the bristles 231. A cylindrical hose connector 7 is fixedly connected to the outer wall of the front end of the brush handle 1. The other end of the rinsing hose 4 extends out of the brush handle 1 and is fixedly connected to the hose connector 7. The rear end of the water spray pipe 6 is inserted into the hose connector 7, thus connecting the rinsing hose 4 and the water spray pipe 6. The outer peripheral wall of the insertion section 13 is in contact with the inner wall of the insertion hole 241. Since both the main body 24 of the brush head 2 and the brush handle 1 are made of plastic, slight deformation of the plastic material can be used during the insertion process of the insertion section 13 into the insertion hole 241 to ensure that the outer peripheral wall of the insertion section 13 is in contact with the inner wall of the insertion hole 241 after insertion, thereby improving the stability of the insertion.

[0026] like Figure 4 and Figure 5 As shown, the brush head 2 includes a main body 24 and a rubber sleeve 23 fitted over the main body 24. The bristles 231 are integrally formed on the outer wall of the rubber sleeve 23. The rear end of the main body 24 forms an insertion hole 241. The other end of the rinsing hose 4 extends into the hose connector 7 and is fixedly connected to the hose connector 7. The fixed connection can be achieved by adhesive bonding or heat fusion bonding, etc.

[0027] like Figure 3 and Figure 5 As shown, the rear end of the brush handle 1 has a connector 14, into which the negative pressure connector 3 is inserted. This design allows for easy assembly during manufacturing. The rinsing hose 4 is first inserted into the brush handle 1 from the front end, with the end of the rinsing hose 4 near the negative pressure connector 3 extending from the connector 14. Then, the rinsing hose 4 is passed through the through hole of the negative pressure connector 3, and the negative pressure connector 3 is then inserted into the connector 14 for fixation.

[0028] like Figure 1 and Figure 4 As shown, the outer wall of the sleeve 23 is provided with a flexible strip 8 that covers the front end of the water spray pipe 6. This design prevents the end of the water spray pipe 6 from contacting the mouth, making the use of this rinsing and suction oral irrigator more comfortable. Specifically, the flexible strip 8 is made of rubber, the middle of the flexible strip 8 covers the front end of the water spray pipe 6, and both ends of the flexible strip 8 are fixedly connected to the sleeve 23.

[0029] In use, the negative pressure connector 3 is connected to the negative pressure suction device. After the syringe is filled with cleaning fluid, the syringe is connected to the syringe connector 5. Then, the operator holds the brush handle 1 with one hand and operates the syringe with the other. The water from the syringe flows through the rinsing hose 4 to the spray pipe 6, and then sprays out from the spray pipe 6 to the bristles 231, wetting the bristles 231 to clean the patient's mouth. When it is necessary to suction out the cleaning fluid from the patient's mouth, the pressing hole 12 is blocked with a finger. At this time, under the negative pressure suction of the negative pressure suction device, the cleaning fluid in the patient's mouth can flow out sequentially through the suction hole 22, the suction chamber 21, the suction channel 11, and the negative pressure connector 3.

[0030] In this rinsing-suction oral irrigator, the front end of the brush handle 1 has a cylindrical insertion section 13 with a reduced outer diameter, while the rear end of the brush head 2 has an insertion hole 241 that communicates with the suction chamber 21. This allows for easy replacement of the brush head 2; simply remove the brush head 2, replace it with a new one, and insert the insertion section 13 of the brush handle 1 into the insertion hole 241 of the new brush head 2. Simultaneously, the hose connector 7 can be connected to the water spray pipe 6, thus connecting the rinsing hose 4 to the water spray pipe 6. Clearly, after a period of use, once the cleaning ability of the brush head 2 decreases, only the brush head 2 needs to be replaced, rather than the entire rinsing-suction oral irrigator, thereby reducing operating costs.

[0031] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0032] Although this document frequently uses terms such as 1. brush handle; 11. suction channel; 12. pressing hole; 13. insertion section; 14. insertion interface; 2. brush head; 21. suction chamber; 22. water suction hole; 23. rubber sleeve; 231. brush bristles; 24. main body; 241. insertion hole; 3. negative pressure connector; 4. rinsing hose; 5. syringe connector; 6. water spray pipe; 7. hose connector; 8. flexible strip, the possibility of using other terms is not excluded.
