Example Embodiment

[0014] The technical scheme of the present invention will be further described in detail below in conjunction with the drawings and preferred embodiments.

[0015] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the multi-point negative pressure drainage device includes PU wound dressing 1. A large suction cup 6 and four small suction cups 4 are placed on the surface of PU wound dressing 1. The large suction cup 6 is located in the middle of PU wound dressing 1, and four small suction cups 4 are distributed Around the large suction cup 6, in practical applications, the number of small suction cups 4 can be set according to needs. The large suction cup 6 is provided with at least two socket holes 61, and each small suction cup 4 is provided with at least two socket holes 41. The head plug 31 of the outer drainage tube 3 is in the shape of a toothed cone. The head plugs at both ends of the double-ended catheter 2 are the same as the head plug 31 of the outer drainage t...

Abstract

The invention discloses a multi-point vacuum drainage device which is applicable to wound therapy for the surface of a human body and comprises PU (polyurethane) wound dressing. A large sucker and at least two small suckers are placed on the surface of the PU wound dressing, the large sucker is positioned in the middle of the PU wound dressing, the small suckers are distributed on the periphery of the large sucker, at least two jacks are formed in each of the large sucker and the small suckers, a head plug of an outer drainage tube and head plugs at two ends of a double-head guide tube are conical, the head plugs can be inserted into an optional jack and can be hermetically connected into the optional jack, the tail of the outer drainage tube is connected with a drainage container by a straight joint, and the drainage container is connected with a vacuum source by a guide tube. The multi-point vacuum drainage device with the structure has the advantages that the problem of air leakage of an extending portion of a drainage tube during vacuum drainage operation is solved, liquefied substances are drained by the large sucker and the small suckers in a multi-point manner, accordingly, a vacuum drainage effect of the vacuum drainage device is improved, and the service life of the vacuum drainage device is prolonged.

Description

technical field [0001] The invention relates to a medical negative pressure drainage device, in particular to a multi-point negative pressure drainage device suitable for treating human body surface wounds. Background technique [0002] Negative Pressure Sealing Drainage Technology (VSD for short) is a brand-new treatment method that promotes wound healing through controllable negative pressure, and has been widely used in medicine. The basic configuration of existing negative pressure drainage devices includes negative pressure source , drainage tube, porous foam cushion, bio-semipermeable membrane and drainage container, a drainage tube is arranged in the porous foam cushion, and a plurality of small holes are distributed on the side wall of the drainage tube. When in use, the porous foam cushion is placed on On the wound surface, cover the porous foam cushion with a biological semipermeable membrane, seal the porous foam cushion and the drainage tube together on the human...
