Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a rinsing device. Background Technology

[0002] In oral treatment, a syringe is typically inserted into the patient's mouth for irrigation. However, due to the rigidity of the syringe, it can easily cause pain or even puncture the patient's lips or gums. Furthermore, during irrigation, the syringe shape may need to be adjusted according to the location of different teeth, resulting in different shaped syringes contacting gums in areas not being irrigated, thus affecting the user experience. Therefore, an irrigation device is needed to solve these problems. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defect of existing rinsing devices that easily cause pain to users, and to provide a rinsing device.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A flushing device, the flushing device including a needle hub and a needle tube, the flushing device further including:

[0006] A buffer section is sleeved on the needle tube, and the buffer section is located at least at the end of the needle tube that extends into the patient's mouth. The buffer section is a flexible tube.

[0007] In this solution, a buffer section is provided and placed around the outer periphery of the needle. When the needle comes into contact with the patient's mouth, the flexible material of the buffer section reduces the risk of puncturing the patient's lips or gums, thereby improving the patient's experience.

[0008] Preferably, the end of the needle tube opposite to the needle seat has a water outlet, and one end of the buffer part is flush with the end of the needle tube opposite to the needle seat.

[0009] In this solution, the above-mentioned settings are used to prevent the buffer from blocking the water flow at the outlet when water is dispensed from the tip of the syringe, thus ensuring smooth water dispensing.

[0010] Preferably, the buffer portion is provided along the entire length of the needle tube extending from the needle hub.

[0011] In this solution, the above settings are used to avoid direct contact between the oral cavity and the needle when the insertion depth of the needle into the patient's oral cavity is large, thereby further improving the patient's user experience.

[0012] Preferably, the end of the needle tube away from the needle hub is closed, and a water outlet hole is provided on the outer wall near the closed end of the needle tube, and at least one water outlet hole is provided.

[0013] In this solution, the above-mentioned settings are used to create a water outlet hole on the side of the outer wall of the syringe to ensure smooth water flow.

[0014] Preferably, the buffer portion and the outer wall of the needle are spaced apart and form a water outlet channel.

[0015] In this solution, the above-mentioned setup ensures that water flowing from the water outlet on the side of the needle tube flows smoothly into the patient's oral cavity through the water outlet channel.

[0016] Preferably, the buffer portion is provided along its entire length from the needle tube extending out of the needle hub;

[0017] Alternatively, the buffer section may extend from the closed end near the needle tube to the area where the water outlet is located.

[0018] In this solution, through the above-mentioned configuration, the buffer section, which is set throughout, can prevent the needle from directly contacting the oral cavity when the needle is in different shapes, such as a bent state; and the buffer section, which extends from the closed end near the needle to the area where the water outlet is located, can also prevent the needle from directly contacting the oral cavity, and can also reduce the manufacturing cost of the rinsing device.

[0019] Preferably, when the buffer portion extends to the area where the water outlet is located, one end of the buffer portion facing the needle seat is connected to the outer wall of the needle tube by a snap-fit ​​structure.

[0020] In this solution, the above-mentioned settings are used to achieve an effective connection between the non-continuously long buffer section and the needle.

[0021] Preferably, the outer diameter of the needle is in the range of 0.25-1.6 mm.

[0022] In this solution, the above settings are used to limit the size of the needle and avoid the situation where the needle is too large, resulting in an excessively large size after the buffer part is fitted onto the needle.

[0023] Preferably, the syringe is made of stainless steel or hard resin.

[0024] In this solution, the above-mentioned settings are used to ensure the structural strength of the needle tube and prevent it from deforming due to the impact of water flow on the needle holder.

[0025] Preferably, the buffer portion is made of any one of PVC resin, silicone or rubber.

[0026] In this solution, the above-mentioned settings are used to ensure the flexibility of the buffer section when it comes into contact with the oral cavity.

[0027] The positive and progressive effects of this utility model are as follows: By setting a buffer part and covering the outer periphery of the needle tube, the flexible material of the buffer part can reduce the pain or puncture of the patient's lips or gums when the needle tube comes into contact with the patient's mouth, thereby improving the patient's user experience.

[0035] Buffer section 3 Detailed Implementation

[0036] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0037] This embodiment provides a rinsing device, the specific structure of which is as follows: Figure 1 and Figure 2 As shown, the flushing device includes a needle hub 1 and a needle tube 2, and the flushing device also includes:

[0038] The buffer part 3 is sleeved on the needle tube 2 and is located at least at the end of the needle tube 2 that extends into the patient's mouth. The buffer part 3 is a flexible tube.

[0039] Specifically, the needle holder 1 has a mounting hole, and the needle tube 2 is a rigid tube with one end inserted into the mounting hole. The outer wall of the needle tube 2 corresponding to the mounting hole is glued to the hole wall to achieve a fixed connection between the needle holder 1 and the needle tube 2. This is existing technology and will not be described in detail here. In this embodiment, the buffer part 3 is a flexible tube. Both the needle tube 2 and the buffer part 3 are round tubes. In other embodiments, they can also be rectangular tubes, which will not be described in detail here. The buffer part 3 is sleeved on the outer periphery of the needle tube 2. The buffer part 3 can directly contact or be spaced apart from the outer wall of the needle tube 2 to wrap the outer wall of the portion of the needle tube 2 extending from the needle holder 1. Thus, when the needle tube 2 is inserted into the patient's mouth, the mouth only contacts the flexible buffer part 3, thereby reducing the risk of puncturing the patient's lips or gums and improving the patient's experience.

[0040] In this embodiment, the end of the needle tube 2 away from the needle seat 1 is provided with a water outlet 21, and one end of the buffer part 3 is flush with the end of the needle tube 2 away from the needle seat 1.

[0041] Specifically, the water outlet 21 is a through hole opened at the end of the needle tube 2 away from the needle seat 1. Along the axial direction of the needle tube 2, the water outlet 21 passes through the needle tube 2 and is connected to the water supply pipeline at the needle seat 1. By setting the water outlet 21 at the end of the needle tube 2 away from the needle seat 1, when water is used for rinsing into the oral cavity, the water flows out from the end of the needle tube 2, avoiding a change in the direction of water flow that would reduce water output efficiency. The buffer part 3 extends to the end of the needle tube 2 away from the needle seat 1 and is flush with the end of the needle tube 2. This avoids a sudden change in the size of the channel that accommodates the water flow when the water flows from the water outlet 21 into the buffer part 3 and then into the patient's oral cavity, which would cause a decrease in water flow velocity when the length of the buffer part 3 is greater than that of the needle tube 2. In other words, it avoids the situation where the large size of the buffer part 3 increases the water flow resistance when water is discharged from the buffer part 3 alone, thus blocking the water flow velocity at the water outlet 21, and ensuring smooth water output.

[0042] Furthermore, the buffer portion 3 extends continuously from the needle tube 2 out of the needle hub 1. That is, the buffer portion 3 covers the extension of the needle tube 2 beyond the needle hub 1, preventing direct contact between the oral cavity and the needle tube 2 when the insertion depth of the needle tube 2 into the patient's mouth is large, thus further improving the patient's user experience. Alternatively, to avoid the need for the needle tube 2 to bend when rinsing teeth in different locations, the continuous buffer portion 3 covering the needle tube 2 prevents any parts of the needle tube 2 from being partially exposed and directly contacting the oral cavity.

[0043] In another embodiment of this invention, the end of the needle tube 2 away from the needle holder 1 is closed, and a water outlet hole (not shown in the figure) is provided on the outer wall near the closed end of the needle tube 2. At least one water outlet hole is provided.

[0044] Specifically, the end of the needle tube 2 away from the needle holder 1 is closed, which is the closed end. A water outlet hole is provided on the outer wall of the needle tube 2 near the closed end so that water can be discharged through the water outlet hole. Multiple water outlet holes can be provided, or one can be provided, thereby enabling the needle tube 2 to discharge water smoothly.

[0045] Furthermore, a water outlet channel is formed between the buffer section 3 and the outer wall of the needle tube 2 at an interval. Compared to the buffer section 3 being in direct contact with the outer wall of the needle tube 2, the spaced buffer section 3 and the outer wall of the needle tube 2 can form a water outlet channel corresponding to the water outlet hole opened on the outer wall, thus avoiding direct contact between the buffer section 3 and the outer wall of the needle tube 2 and affecting the smooth water outlet of the needle tube 2.

[0046] In this embodiment, the buffer part 3 is arranged along the entire length of the needle tube 2 extending from the needle seat 1. One end of the buffer part 3 is connected to the needle seat 1, and the other end is flush with the end of the needle tube 2 away from the needle seat 1, so as to realize the water outlet channel is arranged along the entire length. Furthermore, the buffer part 3, which is arranged along the entire length, can prevent the needle tube 2 from directly contacting the oral cavity when the needle tube 2 is in different shapes, such as in a bent state.

[0047] like Figure 3 As shown, the buffer section 3 can also extend from the closed end near the needle tube 2 to the area where the water outlet is located. That is, the extension length of the buffer section 3 is less than the full length, which can also achieve the purpose of avoiding direct contact between the needle tube 2 and the oral cavity. In addition, the extension length of the buffer section 3 being less than the full length can also reduce the manufacturing cost of the rinsing device.

[0048] Meanwhile, when the water outlet is opened on the needle tube 2, the buffer part 3 extends to the area where the water outlet is located, and the end of the buffer part 3 facing the needle seat 1 is connected to the outer wall of the needle tube 2 through a snap-fit ​​structure.

[0049] It is understandable that the snap-fit ​​structure is a detachable connection structure in the prior art. For example, a hook is provided on the outer wall of the needle tube 2, and a groove is provided on the inner wall of the buffer part 3 corresponding to the needle tube 2. The hook and the groove cooperate to achieve effective connection between the buffer part 3 and the needle tube 2 when the buffer part 3 is not set in a continuous length.

[0050] Of course, in other embodiments, the buffer part 3 can also be connected to the needle tube 2 by other connection methods, such as adhesive bonding. It should be noted that the end of the buffer part 3 facing the needle seat 1 is sealed with the outer wall of the needle tube 2 to prevent water from flowing out from the end of the buffer part 3 facing the needle seat 1.

[0051] In this embodiment, the outer diameter of the needle tube 2 is in the range of 0.25-1.6 mm. By limiting the size of the needle tube 2, the situation is avoided where the needle tube 2 is too large to fit into the gaps between teeth in the oral cavity after the buffer part 3 is fitted on it.

[0052] In this embodiment, the needle tube 2 is made of stainless steel or hard resin. By restricting the material of the needle tube 2, the structural strength of the needle tube 2 is ensured, and the needle tube 2 is prevented from deforming due to the impact of water flow from the needle holder 1.

[0053] In this embodiment, the material of the buffer part 3 is any one of PVC resin, silicone, or rubber. By restricting the material of the buffer part 3, the flexibility of the buffer part 3 when in contact with the oral cavity is ensured.

[0054] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
