Disclosure of Invention
The utility model aims at solving the technical problem existing in the prior art and providing a separable wound surface negative pressure suction device.
In order to realize the purpose, the utility model discloses a technical scheme as follows:
separable surface of a wound negative pressure suction device, including the negative pressure receiving flask, negative pressure receiving flask top is equipped with negative pressure mouth and collects the mouth, negative pressure mouth joint center negative pressure, collect the mouth and pass through screw thread mouth swing joint through the first end of first drainage tube with the three-way valve, negative pressure ball and VSD dressing are connected respectively to the second end and the third end of three-way valve.
Furthermore, the second end of the three-way valve is connected with the negative pressure ball through a second drainage tube, and threaded connectors are adopted at two ends of the second drainage tube.
Furthermore, a valve is arranged on the second drainage tube.
Further, a gas port is arranged below the negative pressure ball, and a plug is arranged on the gas port.
Further, the VSD dressing includes the bio-semi-permeable membrane, the bio-semi-permeable membrane below is equipped with the dressing, and the pipe combines through sucking disc and VSD dressing to realize the drainage.
Further, the other end of the conduit is connected with a third end of the three-way valve.
The technical scheme can obtain the following beneficial effects:
the utility model discloses simple structure uses in a flexible way for the patient can move about by oneself, need not receive the drainage tube and connect the restriction, also reduces the length of drainage tube, keeps bed body pipeline clear, reduces pipeline overlength intertwine and stumbles people's risk.
The utility model discloses each junction all connects through the screw thread mode, and the leakproofness is good, and each part can adopt disposable or adopt the reuse material, practices thrift use cost.
Through the conversion between the central negative pressure and the negative pressure ball, the continuous negative pressure drainage is realized, and the VSD drainage technology is not delayed or prevented from being carried out.
Drawings
Fig. 1 is a structural diagram of the present invention.
In the figure:
in the figure: 1. a negative pressure collection bottle; 2. a bottle cap; 3. a first draft tube; 4. a three-way valve; 5. a VSD dressing; 6. a valve; 7. negative pressure ball, 8, plug, 9, gas port, 10, second drainage tube, 11, pipe.
Detailed Description
The invention will be further explained with reference to the drawings:
as shown in fig. 1, detachable wound surface negative pressure suction device, including negative pressure receiving flask 1, 1 top of negative pressure receiving flask is equipped with negative pressure mouth and collection mouth, negative pressure mouth joint center negative pressure, the first end that the collection mouth passes through first drainage tube 3 and three-way valve 4 passes through screw thread mouth swing joint, and negative pressure ball 7 and VSD dressing 5 are connected respectively to three-way valve 4's second end and third end. The second end of the three-way valve 4 is connected with the negative pressure ball 7 through a second drainage tube 10, and two ends of the second drainage tube 10 are both provided with threaded interfaces. And a valve 6 is arranged on the second drainage tube 10. An air port 9 is arranged below the negative pressure ball 7, and a plug 8 is arranged on the air port 9. VSD dressing 5 includes the bio-semi-permeable membrane, the bio-semi-permeable membrane below is equipped with the dressing, and pipe 11 combines through the sucking disc and VSD dressing 5 to realize the drainage. The other end of the conduit 11 is connected with the third end of the three-way valve 4.
Example (b):
use polyurethane film and polyvinyl alcohol hydration alginate foam (VSD dressing), arrange the patient surface of a wound in, the pipe sucking disc combines fixedly with the VSD dressing, three-way valve 4's third end is connected to the other one end of pipe, three-way valve 4's first end and third end adopt the internal thread interface, the external screw thread interface is all adopted at the both ends of first drainage tube and second drainage tube, then connect three-way valve 4's first end and the collection mouth of negative pressure receiving flask respectively with the both ends of first drainage tube, three-way valve 4's second end and negative pressure ball 7 are connected respectively to the both ends of second drainage tube, need the installation valve on the second drainage tube, the lower extreme of negative pressure ball is equipped with the opening, be equipped with the stopper on the opening, install the bottle lid on the negative pressure receiving flask 1, the bottle lid is equipped with negative pressure mouth and receiving mouth respectively, the negative pressure mouth passes through hose connection center negative pressure.
When the patient is in bed, rotatory three-way valve 4 for unobstructed (collection mouth, second drainage tube and the negative pressure ball of negative pressure receiving flask 1 interrupt) between the collection mouth of negative pressure receiving flask 1, first drainage tube, pipe 11 and the VSD dressing, carry out the wound and last negative pressure drainage, in time discharge micropore and drainage tube in with various exudates through the VSD dressing, effectively promote the wound healing.
