Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a coupling agent smear bag. Background Art

[0002] The main function of the coupling agent is to remove the air between the probe and the skin surface, so that the ultrasound can be effectively transmitted to the skin, ensuring that there is a sufficient amount of sound intensity transmittance on the detection surface, and achieving the purpose of detection. Secondly, the coupling agent has an excessive effect, reducing the acoustic impedance difference between the probe and the skin, reducing the reflection loss of ultrasound energy at this interface, and in addition, the coupling agent with a certain fluidity can also reduce friction. When using the direct contact method for detection, it plays a lubricating role in the movement of the probe on the skin, so that the probe can slide flexibly for inspection; in the process of ultrasonic diagnosis and treatment, it is filled or coated between the radiation surface of the ultrasound probe and the human epidermis, and is used as an intermediary medium for transmitting and conducting ultrasound. Its function is to reduce the conduction resistance of ultrasound, reduce the interference of air between the skin and the probe on the sound wave, and improve image clarity.

[0003] When applying coupling agent, the existing coupling agent application device often applies the corresponding coupling agent based on the experience of medical staff, that is, the amount of coupling agent applied is uncertain. If too little is applied, the examination will be inaccurate, which will take a lot of time and need to be re-applied, which will increase the burden on medical staff. If too much is applied, it will cause waste. Therefore, there is an urgent need for a coupling agent application device that can apply a quantitative amount of coupling agent. Utility Model Content

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0016] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] The following is combined with Figure 1 The utility model is further described in detail:

[0018] Reference Figure 1 The utility model provides a coupling agent smear bag, comprising a bag body 1, the edge of the bag body 1 is sealed, the opening 11 of the bag body 1 is sealed by a drawstring 12, and a drawstring buckle 13 connected to the drawstring 12 is provided on the bag body 1;

[0019] A certain amount of coupling agent is stored in the bag body 1 , and a coating layer 17 is provided on the bag body 1 extending outward from the opening 11 , and the coating layer 17 is a multi-layer gauze.

[0020] Specifically, one side of the opening of the bag body 1 extends outward, and multiple layers of gauze are fixedly connected at the extension by glue, so that the coupling agent flows out from the opening 11 and flows onto the gauze layer, and is smeared to the corresponding position through the gauze layer. In this way, the smearing is more uniform and a quantitative coupling agent is stored in the bag body 1. The coupling agent can meet the amount of normal inspection. This arrangement will not cause waste and is more convenient to use.

[0021] In this embodiment, the bag body 1 can be a circle, a regular polygon, or a specified shape set according to user needs. Figure 1 The bag body 1 is rectangular, and the edges of the four sides of the bag body 1 are sealed. The sealing method can be glue bonding, heat sealing and pressing process or other methods that can achieve the sealing effect.

[0022] Furthermore, a partition layer 14 is provided in the bag body 1 , and the partition layer 14 divides the inner cavity of the bag body 1 into a coupling agent receiving cavity 16 and a gas storage cavity 15 .

[0023] Specifically, the partition layer 14 is arranged in the middle of the bag body 1, and the coupling agent receiving chamber 16 and the gas storage chamber 15 are evenly divided. In other embodiments, the partition layer 14 can be arranged at a designated position as needed, and divided into independent coupling agent receiving chambers 16 and gas storage chambers 15, and the proportion of the coupling agent receiving chamber 16 and the gas storage chamber 15 to each other is not limited.

[0024] Furthermore, the partition layer 14 is provided with a separation line 141, and the separation line 141 is subjected to an external force to form a channel between the coupling agent receiving chamber 16 and the gas storage chamber 15, so that the gas in the gas storage chamber 15 pushes the coupling agent in the coupling agent receiving chamber 16 to be discharged outward. When the separation line 141 receives an external force, such as an external force such as bending or twisting imposed by humans, or an extrusion force or a breaking force by squeezing the gas toward the gas storage chamber 15, the external force forms a channel between the coupling agent receiving chamber 16 and the gas storage chamber 15, and the gas enters the coupling agent receiving chamber 16 and pushes the coupling agent to be discharged from the opening 11.

[0025] In addition, the isolation line 141 is one or more of an arc shape, a folded shape, a V shape, a line segment shape or a sawtooth shape. Among them, the arc-shaped isolation line 141 is easy to be subjected to external force to form a channel; the sawtooth-shaped isolation line 141, because the oblique angle of the "teeth" is facing the coupling agent receiving chamber 16, the coupling agent in the coupling agent receiving chamber 16 will not flow back, and the effect of unidirectional conduction is achieved. Of course, other shapes meet the requirements.

[0026] In this embodiment, the bag body 1 is one or more of polyester film, aluminum foil or polyethylene film, and is arranged in layers. The material and structure are selected for production according to the needs of users.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
