Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, this utility model is further described.
In the application " on ", the direction such as D score all with present specification accompanying drawing 2 for observation visual angle so that make to describe clearly, do not limit the specific direction of this utility model when reality uses.
Fig. 1 is the axonometric chart of the embodiment of a kind of Simple negative-pressure device of this utility model; Fig. 2 is the front view of the embodiment of a kind of Simple negative-pressure device of this utility model; Fig. 3 is the sectional view of the embodiment of a kind of Simple negative-pressure device of this utility model.With reference to accompanying drawing, a kind of Simple negative-pressure device that this utility model provides comprises negative pressure bottle 1, piston 11, connecting rod 13, pallet 15 and valve 19, wherein, the middle part of negative pressure bottle 1 lower surface arranges porose, and negative pressure bottle 1 upper surface is provided with valve 19, and valve 19 is connected to the first conduit 2, and remainder seals, Fig. 4 is the enlarged diagram of a-quadrant in Fig. 3, with reference to figure 4, piston 11 is arranged in negative pressure bottle 1, and the diameter of piston 11 is slightly less than the internal diameter of negative pressure bottle 1, piston 11 side is provided with groove, one-way sealing seal 12 is provided with in this groove, seal between this one-way sealing seal 12 and piston 11, with the Contact of negative pressure bottle 1, and when piston 11 moves upward relative to negative pressure bottle 1, one-way sealing seal 12 allows gas to enter below piston 11 through one-way sealing seal 12 above piston 11, when piston 11 moves downward relative to negative pressure bottle 1, one-way sealing seal 12 does not allow gas to enter above piston 11 through one-way sealing seal 12 below piston 11, piston 11 forms sealed environment, only the first conduit 2 one place and extraneous UNICOM with negative pressure bottle 1 upper surface and negative pressure bottle 1 sidewall, middle part under piston 11 is provided with connecting rod 13, and connecting rod 13 is connected to outside pallet 15 by the hole that negative pressure bottle 1 lower surface is arranged, pallet 15 is removably provided with negative pressure block 17, and pallet 15 can be pulled away from negative pressure bottle 1 by support or gravity by negative pressure block 17, and then drives piston 11 to move by connecting rod 13, and is located by piston 11, thus forms subnormal ambient in negative pressure bottle 1.
In the present embodiment, negative pressure bottle 1 is connected to receiving flask 3 by the first conduit 2; Receiving flask 3 comprises lid 31 and bottle 33, is threaded connection therebetween and surrounds seal cavity; First conduit 2 is connected to lid 31 and UNICOM inner with receiving flask 3; Lid 31 being also provided with second conduit 4, second conduit 4 one end stretches in receiving flask 3 through lid 31, and the second conduit 4 connects with the drainage tube being arranged at wound surface place away from one end of receiving flask 3; Bottle 33 surface is provided with scale marker, is convenient to leaching rate and the seepage discharge of observing, recording wound transudate.Due to negative pressure bottle 1 and receiving flask 3 UNICOM, the two air pressure is identical, and therefore receiving flask 3 also can form subnormal ambient, and then by the second conduit 4 by wound transudate inhaler; Lid 31 and bottle 33 are quick detachable design, transudate collect reach a certain amount of after can easily bottle 33 be taken off, again take back after the transudate process of collecting, then negative pressure bottle 1 is reset to negative pressure state, negative pressure drainage can be proceeded, without the need to the conduit in mobile wound, convenient operation.
In the present embodiment, the edge of pallet 15 upper surface protrudes to negative pressure bottle 1 and forms one week anti-fall edge; Negative pressure block 17 is oblate cylinder, along radius, its side is provided with a groove by the center of circle of negative pressure block 17, and the width of groove is slightly larger than the diameter of connecting rod 13; Can easily by the groove of connecting rod 13 through setting on negative pressure block 17, thus be positioned on pallet 15 by negative pressure block 17 in use, owing to being provided with anti-fall edge at pallet 15 edge, even if therefore negative pressure bottle 1 shakes, negative pressure block 17 also not easily drops.
In the present embodiment, negative pressure bottle 1 is provided with hook, negative pressure bottle 1 top or side can be arranged on, can hang on infusion support or bedside railing; In other embodiment, receiving flask 3 is also provided with hook, is convenient to be suspended on negative pressure bottle 1 side.
Negative pressure block 17 can be set to various structures.In the present embodiment, negative pressure block 17 has multiple and makes by metal material, and can mark weight; After being hung up by negative pressure bottle 1, by the negative pressure block 17 of varying number being positioned over pressure pallet 15 adjusted in negative pressure bottle 1, according to the difference of mark weight, the pressure in negative pressure bottle 1 can be changed quantitatively; The diameter of the negative pressure block 17 varied in weight is different.In other embodiment, negative pressure block 17 has multiple and makes by light material, by the negative pressure block 17 of varying number being supported in the pressure adjusted between negative pressure bottle 1 and pallet 15 in negative pressure bottle 1.
Take Fig. 1 as observation visual angle, piston 11 in use, is first moved to negative pressure bottle 1 top by a kind of Simple negative-pressure device that the present embodiment provides, and by emptying for the air between piston 11 and negative pressure bottle 1, and keeps valve 19 to open; Then negative pressure bottle 1 and receiving flask 3 are suspended near wound position, the second conduit 4 is connected with the conduit being arranged at patient's wound place; Finally, pallet 15 arranges appropriate negative pressure block 17, the gravity of negative pressure block 17 can drive pallet 15 to move down and then in negative pressure bottle 1 and receiving flask 3, form subnormal ambient, Open valve 19, starts drain; If now negative pressure bottle 1 internal gas pressure is too high, then valve-off 19, pallet 15 is moved up until piston 11 and negative pressure bottle 1 tip contact, then Open valve 19 discharge pallet 15, make its free-falling until pressure equilibrium in the gravity of negative pressure block 17 and negative pressure bottle 1; If negative pressure bottle 1 internal gas pressure is still too high, said process can be repeated until air pressure reaches desired value.When the transudate in receiving flask 3 reaches a certain amount of, taken off by bottle 33, cleaning transudate, moves to negative pressure bottle 1 top by piston 11 simultaneously and lifts pallet 15 and stop it to move, then reinstalled by bottle 33, unclamp pallet 15, proceed negative pressure drainage; If now negative pressure bottle 1 internal gas pressure is too high, the process that can repeat when starting drain adjusts.
Can find out, a kind of Simple negative-pressure device that this utility model provides, by arranging negative pressure bottle 1 and receiving flask 3, is convenient to observe transudate collecting amount and clear up transudate in time; Negative pressure block 17 is by gravity or support force simultaneously, and for negative pressure bottle 1 provides negative pressure, structure is simple, and can change vacuum magnitude by the quantity of adjustment negative pressure block 17, easy to operate; Whole apparatus structure is simple, is easy to operation, and does not need power supply support, can be widely used in various occasion.
Those of ordinary skill in the field are to be understood that: the foregoing is only specific embodiment of the utility model; be not limited to this utility model; all within spirit of the present utility model and principle; any amendment of making, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
