Description

Technical Field

[0001] The utility model relates to the technical field of coupling agent coating, and more specifically to a medical coating device. Background Art

[0002] B-ultrasound is a common medical imaging technology, mostly used in gynecology to observe the structure of internal organs and tissues of the human body. When performing a B-ultrasound examination, a substance called a coupling agent is usually required to help spread the ultrasound and ensure good contact between the human skin and the probe. The coupling agent is usually a gel-like substance that can help reduce the reflection of ultrasound when it passes through the skin, thereby improving the clarity of the image. It also helps to eliminate the isolation of air between the probe and the skin, as air interferes with the propagation of ultrasound.

[0003] The Chinese patent announcement number CN219398692U discloses a coupling agent coating device, which operates a moving rod to move downward along a fixed plate, so that the moving rod moves downward to drive the extrusion plate to move downward, and then the extrusion plate moves downward to clean the inner wall of the placement barrel, thereby making it easier for an operator to operate parts to clean the inner wall of the device, thereby preventing the operator from having residual coupling agent on the inner wall of the device after using it, reducing the waste of coupling agent during use, and further enhancing the role of the operator operating parts to clean the device.

[0004] The coupling agent needs to be applied directly to the human skin, so the application device will be in direct contact with the skin. The application head of the device in the above scheme is non-disposable. If multiple people use the same application head, cross-infection is likely to occur. If it is cleaned after one use, it will easily cause inconvenience in use and is not conducive to improving the efficiency of use.

[0005] Therefore, it is necessary to provide a medical application device to solve the above problems. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] Based on this, the problem in the related technology that the applicator head is non-disposable can be improved. If multiple people use the same applicator head, cross infection is likely to occur. If it is cleaned after one use, it will easily cause inconvenience in use and is not conducive to improving the efficiency of use.

[0037] The outer ends of the outer shell 1 are respectively provided with a display screen 2 and an electrical connection port 4 , and a plurality of adjustment buttons 3 are installed on the outer end of the outer shell 1 , and anti-skid side pads 5 are installed on both sides of the outer shell 1 .

[0038] The device in this scheme is mainly used in gynecological B-ultrasound examinations, so that medical staff can apply the coupling agent used for testing to patients. The coupling agent allows ultrasound waves to propagate from the probe to the skin and pass through body tissues to produce clear images, reducing the reflection of ultrasound waves between the probe and the skin, thereby improving the quality of imaging and helping to eliminate the air gap between the probe and the skin, which helps to reduce interference and improve image clarity.

[0039] A coupling agent is stored inside the outer shell 1, and an extrusion component 8 is installed on the top of the outer shell 1. The extrusion component 8 is mainly used to squeeze out the coupling agent inside the outer shell 1. The bottom end of the outer shell 1 is connected to the liquid outlet component 7, and the liquid outlet component 7 is used to discharge liquid. When the coupling agent inside the outer shell 1 is squeezed out, it can be dispersed to facilitate subsequent smearing. An outer protective component 6 is detachably sleeved on the outer end of the liquid outlet component 7. A plurality of limit blocks 64 are fixed at the inner edge of the outer protective sheath 61, and a plurality of limit grooves 72 are provided on the outer surrounding of the rotating block 71. A friction strip 73 is fixed inside the limit groove 72. The friction force between the limit block 64 and the friction strip 73 can make the outer protective sheath 61 easy to remove from the rotating block 71. A new outer protective component 6 can be directly replaced each time it is used to avoid cross infection and improve the efficiency of use.

[0040] A heating component 9 is arranged inside the outer shell 1. The heating component 9 is mainly used to heat the coupling agent stored inside the outer shell 1. When the temperature is low, heating the coupling agent can make the skin feel warmer, which helps to reduce the patient's discomfort and improve the comfort of the examination. At the same time, a plurality of heating nets 10 are arranged at the bottom of the outer shell 1 near the liquid outlet area. The heating nets 10 are in direct contact with the coupling agent, so the heating nets 10 can quickly heat the extruded coupling agent. When the device is used again after a long power outage, since the heating component 9 heats all the coupling agents inside the outer shell 1, it takes a long time to heat. At this time, the heating net 10 can be used to heat the extruded coupling agent first to prevent the heating component 9 from failing to heat quickly when it is just started, thereby reducing the waiting time.

[0041] A display screen 2 is provided at the outer end of the outer shell 1, and the display screen 2 is mainly used to display parameters such as temperature, working gear or mode. A plurality of adjustment buttons 3 are installed below the display screen 2, and the adjustment buttons 3 are used to adjust the gear or temperature to control the heating network 10 and the heating component 9 to work. An electrical port 4 is also provided at the outer end of the outer shell 1, and the electrical port 4 is mainly used to connect the power supply line to supply power to the heating component 9 and the heating network 10. Anti-slip side pads 5 are installed on both sides of the outer shell 1, and the anti-slip side pads 5 are mainly used for easy holding and play an anti-slip role.

[0042] Optionally, in some embodiments, see Figure 2 and Figure 4 The heating assembly 9 includes a heat-insulating layer 91 , which is fixedly connected to the inner wall of the outer shell 1 , an inner lining layer 92 is installed inside the heat-insulating layer 91 , and a heating layer 93 is arranged between the inner lining layer 92 and the heat-insulating layer 91 .

[0043] The thermal insulation layer 91 in this scheme is fixed on the inner wall of the outer shell 1, and mainly plays the role of heat insulation. An inner lining layer 92 is installed on the inner side of the thermal insulation layer 91, and a heating layer 93 is arranged outside the inner lining layer 92. The heating layer 93 is mainly composed of a plurality of groups of mutually wound electric heating wires for heating. The inner lining layer 92 is mainly used to transfer the heat emitted by the heating layer 93 to the inside of the outer shell 1 to heat the coupling agent. A temperature sensor is also arranged on the inner side of the inner lining layer 92. When the coupling agent temperature is heated to between 35°C and 40°C, the heating layer 93 will reduce the heating power to keep the coupling agent warm.

[0044] Optionally, in some embodiments, see Figure 2 and Figure 3 The extrusion assembly 8 includes a cap 81 and a threaded rod 82 . The cap 81 is threadedly connected to the top of the outer shell 1 . A threaded block 84 is fixedly connected to the top of the cap 81 . The threaded rod 82 is threadedly connected to the threaded block 84 .

[0045] A knob 85 is fixedly connected to the top end of the threaded rod 82 , and a movable plug 83 is rotatably connected to the bottom end of the threaded rod 82 . The movable plug 83 is slidably connected to the inner wall of the lining layer 92 .

[0046] The cap 81 in this solution is threadedly connected to the top of the outer shell 1 to seal the outer shell 1. A threaded block 84 is fixed near the middle of the top of the cap 81. The threaded rod 82 extends through the cap 81 to the inside and is threadedly connected to the threaded block 84. A knob 85 is fixed to the top of the threaded rod 82. The bottom of the threaded rod 82 is rotatably connected to the movable plug 83. The knob 85 is mainly used to rotate the threaded rod 82 so that the threaded rod 82 can drive the movable plug 83 to move in the inner lining layer 92. When the movable plug 83 moves downward, it will drive the coupling agent to be squeezed from the outer shell 1 into the liquid outlet component 7.

[0047] Optionally, in some embodiments, see Figure 1 and Figure 5 The liquid outlet component 7 includes a rotating block 71, a ball head 74 is fixedly connected to the top of the rotating block 71, the rotating block 71 is spherically connected to the bottom end of the outer shell 1 through the ball head 74, and a liquid separation groove 75 is arranged inside the rotating block 71, and the liquid separation groove 75 is connected to the inside of the outer shell 1 through the ball head 74.

[0048] A plurality of liquid outlet grooves 76 are provided at the bottom end of the rotating block 71, and sealing rings 77 are installed on the inner walls of the plurality of liquid outlet grooves 76. A plurality of limit grooves 72 are provided on the outer periphery of the rotating block 71, and friction strips 73 are fixedly installed on the inner side of the limit grooves 72. A plurality of limit blocks 64 are fixed on the inner side of the outer sheath 61. The outer sheath 61 is sleeved on the outer periphery of the rotating block 71, and the limit blocks 64 are adapted to the limit grooves 72, and the insert 63 passes through the liquid outlet grooves 76.

[0049] A ball head 74 is fixed on the top of the rotating block 71 in the present solution, and the ball head 74 is spherically connected to the bottom end of the outer shell 1, so that the rotating block 71 can be freely rotated through the ball head 74, so as to facilitate the adjustment of the angle during use. A liquid separation groove 75 is arranged inside the rotating block 71, and the liquid separation groove 75 is connected to the inside of the outer shell 1 through the ball head 74, so that the coupling agent can enter the liquid separation groove 75 through the ball head 74. At the bottom end of the rotating block 71, a plurality of liquid outlet grooves 76 are provided, and the coupling agent in the liquid separation groove 75 will flow out through the plurality of liquid outlet grooves 76, so that it can be evenly distributed, which is convenient for subsequent application.

[0050] The top of the outer sheath 61 is fixed with a side skirt 62, which is inclined outward to play a blocking role. When the outer sheath 61 is applied with the coupling agent, the excess coupling agent is easily accumulated along the edge of the outer sheath 61 and spreads to the rotating block 71. The side skirt 62 can prevent the rotating block 71 from being contaminated by the coupling agent. A plurality of channels are provided at the bottom of the outer sheath 61, which correspond to the liquid outlet grooves 76 one by one and can be connected to each other. On the inner side of the outer sheath 61, that is, just above the through hole The insert 63 is fixed, and when the outer sheath 61 is stuck in the limiting groove 72 on the outside of the rotating block 71 through the limiting block 64, the insert 63 will be inserted into the liquid outlet groove 76 to lead out the coupling agent in the liquid separation groove 75. A sealing ring 77 is fixed on the inner side of the liquid outlet groove 76 to play a sealing role and prevent the coupling agent from flowing from the gap between the liquid outlet groove 76 and the insert 63 to the inside of the outer sheath 61. Therefore, when use is completed, the outer protection component 6 can be quickly removed and then replaced with another one, which can improve hygiene.

[0051] Working principle: A heating component 9 is arranged inside the outer shell 1, which is mainly used to heat the coupling agent, which helps to reduce the patient's discomfort. When using the device, it is necessary to first rotate the knob 85 so that the threaded rod 82 can drive the movable plug 83 to move in the inner lining layer 92, squeeze the coupling agent, and squeeze it from the outer shell 1 into the liquid separation groove 75. At the bottom end of the rotating block 71, a plurality of liquid outlet grooves 76 are provided. The outer sheath 61 is stuck in the limiting groove 72 outside the rotating block 71 through the limiting block 64, and the insert 63 will be inserted into the liquid outlet groove 76 to lead out the coupling agent in the liquid separation groove 75. At this time, the rotating block 71 can be rotated through the ball head 74, so that the outer sheath 61 evenly applies the coupling agent on the skin. When use is completed, the outer protection component 6 can be quickly removed and then replaced with another one to prevent cross infection.
