Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a hydrogel spray device. Background Technology

[0002] Hydrogels, as a highly efficient medical material, have demonstrated outstanding performance in areas such as wound care, pain relief, and drug delivery.

[0003] Chinese Patent 201721626784.4 discloses a hydrogel cooling spray device, relating to the field of medical device technology. It includes a device body, a piston, a nozzle, and a sealing cap. The device body has a hydrogel storage chamber and a spray chamber; the storage chamber and the spray chamber are connected by a channel; a piston is installed inside the spray chamber; one end of the spray chamber has an outlet; the outlet is engaged with the nozzle; the other end of the nozzle is connected to the sealing cap. This invention, by setting up a storage chamber and a spray chamber, allows the operator to simply pull out the piston when using hydrogel for cooling, allowing the hydrogel to flow from the storage chamber into the spray chamber, and then push the piston back into the spray chamber to spray the hydrogel. Furthermore, the inclusion of a circular handle allows for one-handed operation, especially when the arm is injured; it is simple and convenient to use.

[0004] However, when the above-mentioned spray device is in use, because the hydrogel is a colloid, the hydrogel has relatively low fluidity. When the operator pulls out the piston, the hydrogel flows from the storage chamber into the spray chamber through the channel very slowly. The slow use may delay the best treatment time and increase the patient's pain and risk. Therefore, a hydrogel spray device is proposed to solve the above problems. Utility Model Content

A conical nozzle 2 is tightly fitted onto the outer end face of the first connecting pipe 13. An installation component is provided on the outer end face of the shell 3. An installation sleeve 8 is provided on the limiting end of the installation component. The lower opening of the installation sleeve 8 is connected to a cover plate 16 through the limiting component. The collecting component is located inside the installation sleeve 8. The discharge end of the collecting component passes through the upper end face of the installation sleeve 8. The collecting component is connected to the conical nozzle 2 through the connecting component.

[0025] In this invention, during use, by pulling and pushing the component, the hydrogel inside the collector can be drawn into the interior of the outer shell 3 through the connecting component. Then, the connecting component is removed from the upper end of the conical nozzle 2, and the port of the conical nozzle 2 is positioned at the damaged area. The pushing component is then moved, and the conical nozzle 2 can then spray out the hydrogel. When the collector needs to be replaced, the connecting component is first separated from the collector, and then the limiting component opens the cover plate 16, allowing the collector to be removed from the interior of the mounting sleeve 8. The usable collector is then installed inside the mounting sleeve 8, and the cover plate 16 is rotated and limited to the bottom of the mounting sleeve 8 by the limiting component. At this point, the collector passes through the top of the mounting sleeve 8. Then, the cap on the discharge end of the collector is removed, and the connecting component can then be connected to the discharge end of the collector, thus enabling the replacement of the collector.
