Description

Technical Field

[0001] The utility model belongs to the field of medical devices, and particularly relates to a parotid duct irrigator. Background Art

[0002] In oral medical treatment operations, for patients with obstructive parotitis or chronic suppurative parotitis, it is usually necessary to irrigate their parotid ducts to relieve the symptoms. Most clinicians will use a slightly modified syringe to irrigate the parotid ducts.

[0003] However, the needle of the traditional irrigator is sharp and the angle is relatively sharp, resulting in a large resistance during irrigation. Slight carelessness may cause damage to the parotid duct. Moreover, the orientation angle of the irrigation head is relatively fixed and cannot be adjusted according to needs, so the applicable range is limited. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a parotid duct irrigator to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A parotid duct irrigator includes a main body, which includes a syringe barrel, a piston rod disposed in the syringe barrel, a connector disposed at the front end of the syringe barrel, and an irrigation head disposed at the front end of the connector; an adjustment mechanism, which includes an angle adjustment component disposed between the connector and the irrigation head, and a limit component disposed between the connector and the irrigation head; and a reminder mechanism disposed on the syringe barrel.

[0007] Preferably, the angle adjustment component includes a fixing plate disposed on one side of the connector, a rotating plate disposed between the fixing plate and the irrigation head, and a hose disposed between the connector and the irrigation head.

[0008] Preferably, the limit component includes a movable plate disposed on the other side of the irrigation head, a swing arm disposed at the rear end of the movable plate, a card hole disposed on the swing arm, and a plurality of clamping blocks disposed on one side of the connector.

[0009] Preferably, an activity member is disposed between the swing arm and the movable plate, and the clamping blocks are adapted to the card holes.

[0010] Preferably, the reminder mechanism includes a push rod disposed on the piston rod, a plurality of knocking blocks disposed on the syringe barrel, and a knocking ball disposed at the front end of the push rod.

[0011] Preferably, the knocking ball corresponds to the knocking blocks, and scale marks are disposed on the syringe barrel.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] (1) Through the angle adjustment component, the present utility model can adjust the orientation angle of the flushing head as needed, improving the applicable range of the device. When adjusting the orientation of the flushing head, the swing arm will be driven to move synchronously. Then, after the angle adjustment of the flushing head is completed, its position is limited by the limiting component to ensure the stability of the flushing head during the flushing operation.

[0014] (2) Through the reminder mechanism, the present utility model can remind the user after a certain amount of flushing liquid is used, enabling the user to clearly and quickly know the used content and remaining content of the flushing liquid, which is convenient for the user to use.

[0015] (3) The flushing head is smooth to prevent damage to the parotid duct;

[0016] (4) It has a simple structure, is easy to operate, causes little pain to the patient, and is suitable for popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As shown in the attaFigure 1 To Attachment Figure 4 As shown:

[0024] Embodiment 1: The utility model provides a parotid duct flusher, comprising a main body 1, including a syringe 101, a piston rod 102 arranged in the syringe 101, a joint 103 arranged at the front end of the syringe 101, and a flushing head 104 arranged at the front end of the joint 103; an adjustment mechanism 2, including an angle adjustment component 201 arranged between the joint 103 and the flushing head 104, and a limit component 202 arranged between the joint 103 and the flushing head 104; and a reminder mechanism 3, arranged on the syringe 101, wherein the front end of the flushing head 104 is rounded.

[0025] Specifically, the angle adjustment assembly 201 includes a fixed plate 2011 disposed on one side of the joint 103 , a rotating plate 2013 disposed between the fixed plate 2011 and the flushing head 104 , and a hose 2012 disposed between the joint 103 and the flushing head 104 .

[0026] Furthermore, the limiting assembly 202 includes a movable plate 2021 disposed on the other side of the flushing head 104 , a swing arm 2023 disposed at the rear end of the movable plate 2021 , a clamping hole 2025 disposed on the swing arm 2023 , and a plurality of clamping blocks 2024 disposed on one side of the connector 103 .

[0027] Furthermore, a movable part 2022 is provided between the swing arm 2023 and the movable plate 2021 , and the clamping block 2024 is matched with the clamping hole 2025 .

[0028] As can be seen from the above, during operation, the flushing liquid can be sucked into the syringe 101, and then the flushing head 104 can be used to flush the parotid duct. During flushing, the flushing head 104 can be pushed as needed to rotate on the fixed plate 2011 through the rotating plate 2013 to adjust the direction of the flushing head 104, thereby improving the applicable range of the device. Before adjusting the direction of the flushing head 104, the swing arm 2023 can be moved toward the outside of the syringe 101 to rotate toward the outside of the syringe 101 through the movable part 2022, so that the clamping hole 2025 is separated from the clamping block 2024 to release the flushing head 104. To limit the work, after the direction adjustment of the flushing head 104 is completed, the swing arm 2023 is swung up and down to make it rotate up and down through the movable plate 2021, so that the clamping hole 2025 is on the horizontal line where the plurality of clamping blocks 2024 are located, and then the swing arm 2023 is pressed toward the joint 103 to make it rotate in the initial direction through the movable part 2022, so that the clamping hole 2025 is engaged with the nearest clamping block 2024 to limit the current position of the flushing head 104 and ensure stability during the flushing work. The hose 2012 can adjust the angle of the flushing head 104 without affecting the flushing work, which is convenient for personnel to use.

[0029] Embodiment 2: This embodiment is basically the same as the previous one, except that the reminder mechanism 3 includes a push rod 301 arranged on the piston rod 102, several knocking blocks 304 arranged on the syringe barrel 101, and a knocking ball 302 arranged at the front end of the push rod 301.

[0030] Specifically, the knocking ball 302 corresponds to the knocking blocks 304, and a scale mark 303 is arranged on the syringe barrel 101.

[0031] As can be seen from the above, when pressing the piston rod 102 for flushing work, the piston rod 102 will drive the push rod 301 to move synchronously. The user can cooperate with the moving distance of the push rod 301 and the scale mark 303 to clearly know the remaining content of the flushing liquid in the syringe barrel 101. When the knocking ball 302 contacts the knocking blocks 304, a prompt sound will be generated due to the contact collision, and a slight resistance will be generated to remind the personnel, so that the personnel can clearly and quickly know the used content and the remaining content of the flushing liquid.
