Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a color Doppler ultrasound coupling agent applicator. Background Art

[0002] The coupling agent is a medical product composed of a new generation of aqueous polymer gel. Its function is to exclude the air between the ultrasonic probe and the object to be measured, improve the detection clarity of the ultrasonic probe, and has the characteristics of being non-toxic and harmless, not easy to dry, not easy to turn rancid, clear ultrasonic imaging, suitable viscosity, and no greasiness. Ultrasonic examination is a routine examination in hospitals, and a large number of patients are examined every day. Before performing an ultrasonic examination, the ultrasonic department needs to apply the coupling agent to the part to be examined.

[0003] Publication No. CN119033410A discloses a color Doppler ultrasound coupling agent application device, which relates to the field of coupling agent application. It includes an application housing, and an additive end is arranged in the middle of the application housing. The interior of the application housing has an upper cavity and a lower cavity, and a communication channel is provided between the upper cavity and the lower cavity. A discharge port is arranged at the lower part of the lower cavity, and a piston head is slidably connected inside the upper cavity. The upper part of the piston head is fixedly connected with a piston rod. By providing the box body, the electric heating tube, the heat conduction assembly, and the application member, the color Doppler ultrasound coupling agent inside the application housing can be preheated to raise its temperature to a comfortable level, thus avoiding the cold discomfort during application and increasing the comfort of use; by providing the application housing, the discharge port, and the application member, it has a relatively wide release area, and the application member has a wide coverage area, and a large area can be applied in a short time, improving the application efficiency and facilitating application.

[0004] Currently, when the current color Doppler ultrasound coupling agent application device is applying, the coupling agent is first squeezed onto the skin, and then the coupling agent is evenly applied with a cotton swab. The efficiency is relatively low during application, and the extrusion amount of the coupling agent is not easy to control. If too much coupling agent is extruded, it will cause waste, and if too little is extruded, it will reduce the filling effect of the coupling agent between the probe and the skin. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a color Doppler ultrasound coupling agent applicator to solve the problems existing in the above-mentioned background art.

[0006] The present invention provides the following technical solution: A color Doppler ultrasound coupling agent applicator includes a device housing, an adjustment assembly is arranged inside the device housing, a connection card board is fixedly connected to the bottom of the device housing, and the device housing and the connection disk are connected together through the connection card board, which is convenient for installation and disassembly.

The bottom of the support rod is fixedly connected to a connecting plate, and the bottom of the connecting plate is fixedly connected to a movable plate. A driving rod is movably connected to the side of the movable plate, and a driven rod is meshed and connected to the side of the driving rod. A storage assembly is arranged at the bottom of the driven rod. The storage assembly includes a piston disc and a storage box. The driven rod is fixedly connected to the storage box. The bottom of the support rod is fixedly connected to a fixed rod; A storage assembly is arranged at the bottom of the fixed rod. An adjusting turntable is arranged between the storage assembly and the fixed rod, and the adjusting turntable is rotatably connected to the device housing.

[0007] Further, a fixed rod is arranged at the bottom of the driving rod. An adjusting turntable is arranged between the driving rod and the fixed rod, and the adjusting turntable is rotatably connected to the device housing.

[0008] Further, a connecting groove is formed in the adjusting turntable. A second spring is arranged at one end of the connecting groove. The bottom of the second spring is fixedly connected to the adjusting turntable, and the top of the second spring is fixedly connected to an adjusting rod. An adjusting block is fixedly connected to the adjusting turntable, and a notch is formed in the device housing. The adjusting block is arranged at the notch.

[0009] During use, by pressing the adjusting button downward, the adjusting button is driven to move downward. The adjusting button drives the first spring to move downward. The first spring absorbs the pressure and converts it into elastic potential energy. The adjusting button drives the support rod and the connecting plate to move downward. The connecting plate drives the movable plate and the fixed rod to move downward. During the downward movement of the movable plate, the driving rod is driven to rotate. The driving rod drives the driven rod to rotate. The driven rod drives the storage assembly to rotate, so that after pressing the adjusting button, the connecting disc is driven to rotate. At the same time, the downward movement of the connecting plate drives the fixed rod to move. The fixed rod drives the piston disc and the piston plate to move downward, and the coupling agent stored inside the storage box is extruded through the through hole.

[0010] Further, the bottom cover plate includes a connecting rod. A connecting chassis is fixedly connected to the bottom of the connecting rod. A fixed cylinder is fixedly connected to the top of the connecting chassis. Through holes are formed in the connecting chassis.

[0011] Further, a fixed buckle is movably connected to the connecting rod. A limiting hole is formed in the fixed buckle, which is convenient for fixing.

[0012] Further, a roller brush is rotatably connected to the bottom of the connecting chassis. The roller brush is made of silica gel. The silica gel brush has a soft texture and can adapt to different skin surfaces, making the application more uniform.

[0013] Furthermore, the connection disk includes an annular sleeve. A limiting groove is formed in the annular sleeve. A fixing block is arranged at the limiting groove and fixedly connected to the annular sleeve.

A driving rod is fixedly connected to the side of the sliding rod. The side of the driving rod is rotatably connected to the inner wall of the device housing. During use, when the movable plate moves downward, the sliding rod is driven to rotate through the activity groove, so that the sliding rod performs a one-way rotational movement during the entire movement process of pressing the adjustment button and bouncing upward through the first spring.

[0015] Furthermore, a piston plate is fixedly connected to the bottom of the piston disk. A limiting block is fixedly connected to the inside of the storage tank. The piston plate is movably connected to the limiting block. A top connection disk is fixedly connected to the bottom of the storage tank. A discharge hole is formed in the top connection disk. During use, the coupling agent inside the storage tank is extruded by the downward movement of the piston disk and the piston plate. The arrangement of the limiting block can balance the pressure received at the discharge hole and improve the sealing effect of the storage assembly at the same time.

[0016] Beneficial effects: 0. For this color Doppler ultrasound coupling agent applicator, during use, the extrusion amount of the coupling agent each time is related to the pressing force of the adjustment button. That is, each time the adjustment button is pressed to the maximum descent height, the extrusion amount of the coupling agent can be fixed within the standard numerical range. By controlling the initial length of the adjustment button, the extrusion amount of the coupling agent each time can be adjusted. Different amounts of coupling agent can be used for different parts, or the extrusion amount of the coupling agent can be adjusted by pressing the adjustment button multiple times. The adjustment method is more convenient.

[0017] 1. For this color Doppler ultrasound coupling agent applicator, during the pressing process, the downward movement trend is converted into a horizontal rotational movement trend through the movable plate, the driving rod and the driven rod, so that when the coupling agent is extruded, the coupling agent extruded onto the skin can be evenly smeared through the bottom cover plate, improving the smearing efficiency and being simple to operate at the same time.

The bottom of the connecting clamping plate 7 is rotatably connected to a connecting disk 4, and a bottom cover plate 5 is movably connected to the connecting disk 4; The adjustment assembly 1 includes an adjustment button 101. A support rod 103 and a first spring 102 are fixedly connected to the bottom of the adjustment button 101. The first spring 102 is arranged between the support rod 103 and the adjustment button 101. The bottom of the first spring 102 is fixedly connected to the device housing 2. The bottom of the support rod 103 is fixedly connected to a connecting plate 104. The bottom of the connecting plate 104 is fixedly connected to a movable plate 105. A driving rod 106 is movably connected to the side of the movable plate 105. A driven rod 107 is meshingly connected to the side of the driving rod 106. A storage assembly 8 is arranged at the bottom of the driven rod 107. The storage assembly 8 includes a piston disc 801 and a storage tank 802. The driven rod 107 is fixedly connected to the storage tank 802. The bottom of the support rod 103 is fixedly connected to a fixed rod 108.

[0022] A storage assembly 8 is arranged at the bottom of the fixed rod 108. An adjustment turntable 109 is arranged between the storage assembly 8 and the fixed rod 108. The adjustment turntable 109 is rotatably connected to the device housing 2.

[0023] A connecting groove 110 is formed in the adjustment turntable 109. A second spring 112 is arranged at one end of the connecting groove 110. The bottom of the second spring 112 is fixedly connected to the adjustment turntable 109. The top of the second spring 112 is fixedly connected to an adjustment rod 111. An adjustment block 113 is fixedly connected to the adjustment turntable 109. A notch is formed in the device housing 2. The adjustment block 113 is arranged at the notch.

[0024] During use, by pressing down the adjustment button 101, the adjustment button 101 is driven to move downward. The adjustment button 101 drives the first spring 102 to move downward. The first spring 102 absorbs the pressure and converts it into elastic potential energy. The adjustment button 101 drives the support rod 103 and the connecting plate 104 to move downward. The connecting plate 104 drives the movable plate 105 and the fixed rod 108 to move downward. During the downward movement of the movable plate 105, the driving rod 106 is driven to rotate. The driving rod 106 drives the driven rod 107 to rotate. The driven rod 107 drives the storage assembly 8 to rotate, so that after pressing the adjustment button 101, the connecting disc 4 is driven to rotate. At the same time, the downward movement of the connecting plate 104 drives the fixed rod 108 to move. The fixed rod 108 drives the piston disc 801 and the piston plate 803 to move downward, and the coupling agent stored inside the storage tank 802 is extruded through the through hole 504.

[0025] What needs to be specifically explained in this embodiment is that during use, the amount of coupling agent extruded each time is related to the pressing force of the adjustment button 101, that is, each time the adjustment button 101 is pressed to the maximum descending height, the amount of coupling agent extruded can be fixed within the standard numerical range, and the initial length of the adjustment button 101 is controlled to adjust the amount of coupling agent extruded each time, and different coupling amounts are used for different parts, or the coupling agent extrusion amount is adjusted by pressing the adjustment button 101 multiple times. The adjustment method is more convenient, and during the pressing process, the downward movement trend is converted into a horizontal rotation movement trend through the movable plate 105, the driving rod 106 and the driven rod 107, so that when the coupling agent is extruded, the coupling agent extruded on the skin can be evenly applied through the bottom cover plate 5, thereby improving the application efficiency and simplifying the operation.

[0026] At the same time, after the coupling agent is extruded, the adjusting block 113 can be rotated to change the position of the adjusting rod 111. At this time, the adjusting rod 111 and the fixed rod 108 are separated, and pressing the adjusting button 101 will not drive the piston disc 801 and the piston plate 803 to move downward, but will only drive the connecting disc 4 and the bottom cover plate 5 to rotate, which is mainly used to evenly apply the coupling agent on the skin and improve work efficiency.

[0029] The bottom of the connecting chassis 502 is rotatably connected with a roller brush 507 , which is made of silicone. The silicone brush has a soft texture and can adapt to different skin surfaces, allowing for more even application.

The fixing block 403 is fixedly connected to the annular shell 401. A fixing buckle 506 is provided at the limiting groove 402 and is fixed by the fixing block 403 and the limiting hole 505.

[0031] In this embodiment, it should be specifically noted that: when in use, by pressing the fixing buckle 506 inward, the fixing block 403 is ejected from the limiting hole 505, and the bottom cover plate 5 can be rotated at the limiting groove 402 so that the through hole 504 on the bottom cover plate 5 is aligned with the discharge hole 805 on the storage component 8, facilitating the smooth extrusion of the coupling agent from the storage tank 802. After use, by pressing the fixing buckle 506 inward, the bottom cover plate 5 is moved to the other side so that the fixing cylinder 503 on the bottom cover plate 5 is aligned with the discharge hole 805 on the storage component 8, and the discharge hole 805 is blocked by the fixing cylinder 503, enabling the storage component 8 to be closed and better preserving the coupling agent inside the storage component 8.
