Detailed Description

Embodiments of the present utility model are described in further detail below with reference to the accompanying drawings and examples. The following examples are illustrative of the utility model but are not intended to limit the scope of the utility model.

As shown in fig. 1 to 4:

Embodiment one: the utility model provides a simple and convenient self-made VSD negative pressure suction device, which comprises a suction bottle 1, a suction mechanism 2 arranged on the suction bottle 1 and an auxiliary mechanism 3 arranged on the suction mechanism 2.

Specifically, the suction bottle 1 is provided with a connection hose 101 at the top.

Further, the suction mechanism 2 includes a suction hose 201 provided to the suction bottle 1, and a first check valve 204 is attached to one side of the suction hose 201 through a first tee 203, and an airbag 202 is attached to one side of the first check valve 204 through a second tee 205.

From the above, when in use, the connecting hose 101 and the external dressing can be connected together, after the dressing is applied on the wound, the air bag 202 is pressed to extrude the air in the air bag 202, the first one-way valve 204 can prevent the air from entering the suction bottle 1 through the suction hose 201, the air bag 202 can be elastically spread after the air bag 202 is released, so that the air in the suction bottle 1 is pumped out through the first one-way valve 204, the wound liquid of a patient is sucked into the suction bottle 1 by using the connecting hose 101, the effect of promoting wound healing is achieved, the suction bottle 1 can be replaced by a plastic or glass bottle, the connecting hose 101 and the suction hose 201 can be replaced by a silica gel hose, the one-way valve and the three-way pipe can be purchased in the market, the user can easily self-make at home, the production and use cost is reduced, and the user can use conveniently.

Embodiment two: the present embodiment is basically the same as the previous embodiment, except that the auxiliary mechanism 3 includes a housing 301 disposed between the first tee 203 and the second tee 205, a piston plate 308 is mounted inside the housing 301 through a spring 309, a baffle 306 is mounted on one side of the piston plate 308, and an open slot 307 is formed on the surface of the housing 301, wherein the housing 301 can be replaced by a common syringe, and the housing can be used after the open slot 307 is formed on the surface thereof.

Specifically, the slot 307 is configured in a drop shape, when air enters the housing 301, the air is blown out of the housing 301 through a narrower portion of the slot 307, because the slot 307 is narrower and the air flow rate of the air extruded by the air bag 202 is too fast, the piston plate 308 is pushed to move toward the other side of the device, when the air in the air bag 202 is completely output and the piston plate 308 moves to a wider position of the slot 307, the spring 309 can push the piston plate 308 back to the original position rapidly through self elasticity, and the air in the housing 301 on one side of the piston plate 308 is extruded out of the housing 301 through the slot 307, so that the situation that the air influences the reset of the piston plate 308 is avoided.

Further, a second one-way valve 302 is installed between the housing 301 and the second three-way pipe 205, a third three-way pipe 304 is installed at the other side of the housing 301, a fourth one-way valve 305 is installed between the third three-way pipe 304 and the first three-way pipe 203, and a third one-way valve 303 is installed at the top of the third three-way pipe 304.

As can be seen from the above, when the user presses the air bag 202, air is input into the housing 301 through the second three-way tube 205, the second one-way valve 302 can prevent air in the housing 301 from flowing back into the air bag 202 again, and the air in the housing 301 pushes the piston plate 308 to move towards the other side of the device, so that air in the housing 301 on the other side of the piston plate 308 is pushed out and blown out of the device through the third one-way valve 303, the fourth one-way valve 305 can prevent the pushed air from reentering the suction bottle 1 through the suction hose 201 to affect the negative pressure suction operation, and when the air in the air bag 202 is pushed out and expanded, the spring 309 pushes the piston plate 308 towards one side of the device through its own elasticity, and during the process, the liquid product of the wound part of the patient is pumped into the suction bottle 1 through the fourth one-way valve 305 by negative pressure, and when the air bag 202 is pressed, the negative pressure suction operation can be performed simultaneously with the housing 301, thereby improving the negative pressure suction efficiency and effect.

Working principle: during operation, the connecting hose 101 is connected with the dressing, the air bag 202 is pressed after the dressing is applied to the wound, air in the air bag 202 enters the shell 301 through the second one-way valve 302 after being extruded, then the piston plate 308 is pushed towards the other side direction, after the air bag 202 is loosened, the air bag 202 can pump negative pressure of the wound of a patient into the suction bottle 1 through self-expansion for centralized collection, in the process, the spring 309 can push the piston plate 308 towards one side direction of the device through self elasticity, so that negative pressure of the wound of the patient is pumped into the suction bottle 1 through the fourth one-way valve 305, and the negative pressure suction effect and efficiency are improved.

While embodiments of the present utility model have been shown and described above for purposes of illustration and description, it will be understood that the above embodiments are illustrative and not to be construed as limiting the utility model, and that variations, modifications, alternatives, and variations may be made to the above embodiments by one of ordinary skill in the art within the scope of the utility model.
