Description
Technical Field
The utility model relates to the technical field of material mixing, in particular to a hydrogel mixing injection needle.
Background
Because some hydrogel which needs to be injected subcutaneously is formed by mixing two or more components, and is required to be used immediately after being mixed uniformly when in use, the workload is huge in the process of mixing the components of the fluid by nurses, and the hidden danger that the components are polluted by the environment exists, the operation difficulty is large, the technical requirement is high, and how to provide the hydrogel mixing injection needle which is effective in mixing, simple in assembly and low in loss becomes the research subject of the utility model. The utility model adopts a double-layer spiral structure to mix medicines, the upper part of the confluence cavity is wide and the lower part of the confluence cavity is narrow, the confluence cavity and the tube body are integrally formed, and the injection needle is fixedly connected to form a sterile environment.
The mixing needle is a common multi-component mixing device, but the common industrial mixing syringe has larger volume and is not easy to take, and the application of the mixing needle in the field of medical devices is limited.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
Aiming at the defects of the prior art, the utility model provides a hydrogel mixing injection needle, which solves the problems of huge workload, difficult assembly, large loss and hidden danger of drug environmental pollution in the background technology.
(II) technical scheme
In order to achieve the purpose, the utility model is realized by the following technical scheme: the utility model provides a hydrogel mixing syringe needle which includes that the body its characterized in that: the novel multifunctional vortex generator is characterized in that a tube center shaft is clamped in the center of the interior of the tube body, two layers of propeller blades are connected to the center of the tube center shaft, a converging cavity is fixedly connected to one end of the tube body, a needle head is connected to the converging cavity, and a threaded connector is connected to one end, far away from the converging cavity, of the tube body.
The threads of the threaded interface reside inside the interface. The number of the propeller blades connected with the central shaft of the pipe is two.
The ferrule interface, the tube body and the manifold cavity are made of polypropylene.
One end of the pipe body is connected with a flow converging cavity, and the flow converging cavity is wide at the top and narrow at the bottom and is integrally formed.
The tube middle shaft and the propeller blade are integrally formed.
The No. 5 syringe needle is stainless steel.
(III) advantageous effects
The utility model provides a hydrogel mixed injection needle, which has the following beneficial effects:
1. the hydrogel mixing injection needle rotates naturally along with the filling of fluid components through the helical blades in the tube body to mix and convey the fluid components,
2. this aquogel mixes syringe needle, the chamber of converging that connects through body one end, the chamber lower extreme fixedly connected with syringe needle converges, facilitates for hypodermic injection.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is an enlarged view of the tube shown in FIG. 1 according to the present invention;
in the figure: 1-a threaded interface, 2-a tube body, 3-a propeller blade, 4-a tube middle shaft, 5-a converging cavity and 6-a needle head.
Detailed Description
The technical solution in the embodiment of the present invention will be further described with reference to the accompanying drawings in the embodiment of the present invention.
Referring to fig. 1 to 2, the present invention provides a technical solution: a hydrogel mixing injection needle comprises a threaded interface 1 connecting pipe
The body 2, the 1 screw thread of hickey exist inside the interface, and the inside center joint of body 2 has a pipe axis 4, pipe axis 4 center connection has two-layer propeller blade 3, along with fluid component's packing into, propeller blade is around the spontaneous rotatory stirring mixed component of axis, the one end fixedly connected with of body 2 converges chamber 5, and the chamber that converges is narrow structure under the upper width, and inside is the inclined plane, has the water conservancy diversion effect, converge chamber 5 and be connected with syringe needle 6, impels syringe needle 6 through converging the chamber, flows out from syringe needle 6, facilitates for hypodermic injection.
The pipe middle shaft 4 and the two layers of the propeller blades 3 are integrally formed, and the propeller blades 3 automatically rotate around the pipe middle shaft 4 after being filled with fluid components.
In conclusion, the hydrogel mixing injection needle head is connected with the needle head through the structure of the upper wide inclined plane and the lower narrow inclined plane of the confluence cavity 5, so that hydrogel obtained by mixing flows out of the needle head, the loss in the discharging process is reduced, convenience is brought to subcutaneous injection, and the condition of material waste is avoided.
The embodiments of the present invention have been described above, and it is intended that those skilled in the art can understand that the embodiments and modifications can be made without departing from the principle and spirit of the present invention, but the scope of the present invention is not limited thereto.
