Description

Technical Field

[0001] The utility model relates to the technical field of gel extrusion devices, in particular to a medical cold compress gel extrusion device. Background Technique

[0002] Medical gels can be used as drug sustained-release systems. Drugs can be embedded in the gels and then gradually released to achieve continuous drug delivery. This method can improve the efficacy of drugs and reduce the frequency of drug use. At the same time, medical gels can be used to fill and repair tissue defects. They can be injected or implanted into specific parts of the body to fill cavities, smooth wrinkles, increase tissue volume or repair damaged tissues. For this reason, a medical cold compress gel extrusion device is proposed.

[0003] The existing Chinese utility model patent with the reference publication number: CN216036141U discloses a medical cold compress gel extrusion device. The setting of this medical cold compress gel extrusion device includes a box body and an installation groove opened on the box body. An extrusion device is arranged inside the installation groove. A screw rod is arranged on the top of the extrusion device. A screw hole for the screw rod to pass through is opened on the box body. A handle is arranged at one end of the screw rod passing through the box body. A winding device is arranged on the box body. In the utility model, one end of the cold compress gel packaging shell is fixed between two clamping plates. By rotating the handle to drive the extrusion device to press down the cold compress gel packaging shell, and rotating the winding sleeve to wind the cold compress gel packaging shell, the cold compress gel packaging shell squeezes the internal cold compress gel to one end close to the outlet under the extrusion of the extrusion plate and the roller. Through the double extrusion of the extrusion plate and the roller, the extrusion effect is better. By adjusting the extrusion degree of the extrusion plate on the packaging shell, it is avoided to damage the packaging shell and cause the gel to be contaminated by the outside world.

[0004] During the use of the existing medical cold compress gel extrusion device, since the gel is a viscous substance, a large amount of it will remain inside the device after extrusion, resulting in incomplete gel extrusion and waste. At the same time, uneven gel extrusion will cause the gel dose to not meet the standard or bubbles to appear inside the gel, which needs to be improved. Therefore, those skilled in the art provide a medical cold compress gel extrusion device to solve the problems raised in the above background technique. Content of the Utility Model
