Embodiment Construction

[0023] In order to further illustrate the feasibility, practicability and ease of operation of the invention patent, the invention patent will be described in detail in combination with schematic diagrams.

[0024] A sprinkler device with wrapping function, such as figure 1 and 2 As shown, it includes a quick connector 1, a quick connector 2, a cone positioning member 3, a nozzle body 4, a set nut 5, a needle 6, a sealing screw 7, a capillary 8, an outer cavity 9, and an inner cavity 10. The nozzle body 4 and the cone positioning part 3 are fixed by threads and the concentricity requirements are maintained by the cone positioning. This structure can prevent the wrapping material from leaking out; The design realizes the positioning of the needle head 6 so as to meet the requirement of coaxiality; the sealing screw 7 plays a role of sealing to prevent leakage of wrapping materials or active biological materials.

Abstract

The invention discloses a nozzle apparatus with a package function, and the nozzle apparatus not only is capable of overcoming the problem that the existing 3D biological printing technology is excessively high in cell death rate, but also can realize the uniform arrangement of biological particles. The nozzle apparatus with the package function mainly comprises a nozzle main body, a conical positioning part, a capillary pipe, a pinhead, a locking nut, a quick connector and a sealing screw. The nozzle apparatus with the package function has the characteristics that the conical positioning part is fixedly connected with the nozzle main body by virtue of threads and positioned by virtue of conicity; the capillary pipe is in clearance fit with the conical positioning part to be positioned, and the capillary pipe is fixed in an adhesion manner; the pinhead is fixed to the nozzle main body by virtue of the locking nut and positioned by virtue of the conicity at the outlet end of the nozzle main body, so that the coaxiality requirement of the capillary pipe and the pinhead is met; and two cavities are formed between the conical positioning part and the nozzle main body, an inner cavity and an outer cavity are respectively fully filled with different materials, the pressures of the inner cavity and the outer cavity are respectively controlled by virtue of a pressure feedback and control circuit, the flow rate of the biological material in the inner cavity and the outer cavity is further controlled, the package of cells or active biological materials as well as the uniform arrangement of particles are realized, and the nozzle also has the advantage of easiness in machining.

Description

technical field [0001] The patent of the present invention relates to the nozzle manufacturing technology in the field of tissue engineering, and relates to a nozzle device that automatically controls the wrapping of biological materials. Background technique [0002] In recent years, the application of 3D bioprinting technology in bioengineering has brought surprises and hopes to patients with organ diseases, skin burn patients, multi-organ drug screening, and blood vessel structure. With the development of 3D bioprinting technology, it is approaching Millions of disease patients will be born again through 3D bioprinting. However, living cell printing faces a big problem, that is, the immune rejection of the tissue or organ obtained by printing, which is an urgent problem faced by scientific researchers all over the world. According to statistics, China's organ inventory is very low, which is far from enough to meet the demand for organ transplants. There are about 120,000...
