Embodiment 1

[0022] Basic as attached figure 1 and figure 2 Shown: a wound or sinus gel dressing injection device, including a push plate 1 and a push handle 2 integrally formed with the push plate 1, two threaded rods 3 are pierced on the push plate 1, and the threaded rods 3 are threaded with the push plate 1 Connection, the bottom of the threaded rod 3 has a circular groove, the inner diameter of the groove is closed larger than the end of the piston handle of the first syringe 4 and the end of the piston handle of the second syringe 5; the push handle 2 is slidingly connected with an internal hollow The sleeve 6, the bottom of the sleeve 6 has an air outlet; the upper part of the sleeve 6 is also symmetrically adhered to two card seats 7 made of rubber, and one side of each card seat 7 is provided with a threaded rod 3. The clamping hole directly below the clamping hole on the clamping seat 7 on the left side of the push handle 2 is slightly smaller than the outer diameter of the fir...

Embodiment 2

[0026] The difference between this embodiment and Embodiment 1 is that the connecting tube 8 in this embodiment is made of hard material, and the outlet of the lower end of the connecting tube 8 is provided with a wedge surface, which facilitates the connecting tube 8 to be inserted into the wound surface. cavities or sinuses.

Abstract

The invention discloses a wound surface or sinus tract gel dressing injection device, and particularly relates to the technical field of medical instruments. The wound surface or sinus tract gel dressing injection device comprises a push plate and a push handle connected with the push plate, the push handle is connected with a hollow sleeve in a sliding manner; an air outlet hole is formed in oneside of the sleeve, the push handle is further detachably connected with a first injector and a second injector which are both located under the push plate, the volume of the first injector is ten times that of the second injector, and the mastoid of the first injector and the mastoid of the second injector are jointly connected with a Y-shaped connecting pipe. By applying the technical scheme, the problem of high consumable cost in the chronic refractory wound surface treatment process is solved, and the device can be used for treating the wound surface of a patient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a wound or sinus tract gel dressing injection device. Background technique [0002] With the intensification of my country's aging society, according to large-scale epidemiological data, the incidence and prevalence of chronic refractory wounds are increasing year by year. This not only reduces the quality of life of patients, but also increases the medical burden on families and society. After platelet-rich plasma (platelet-rich plasma, PRP) is activated, platelets release a variety of high-concentration growth factors that act synergistically to promote the proliferation and differentiation of local repair cells and the synthesis of extracellular matrix, and have the ability to strengthen tissue regeneration and repair; Compared with traditional methods, it has shown better therapeutic effects in the treatment of chronic refractory wounds such as diabetic foot ulcers, ...
