Description

Improved negative pressure drainage device

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a negative pressure drainage device of improvement.

Background

The negative pressure closed drainage technology VSD is a brand new treatment method that the wound surface with skin and soft tissue defects is covered or filled by using a polyvinyl alcohol hydrated seaweed salt foam dressing with a drainage tube, the wound surface is closed by using a semipermeable bio-membrane to form a closed space, and finally the wound surface is promoted to heal by using a controllable negative pressure of a drainage tube connection source.

Reminding patients and accompanying personnel not to draw, press and fold the drainage tube, and not being capable of randomly adjusting negative pressure. The drainage fluid contains a large amount of protein and high metabolic reaction in a wound state, nutrition support treatment is required, and growth hormone is used for metabolic regulation to promote positive nitrogen balance when necessary; the patient is encouraged to eat high-protein and high-calorie easily digestible food rich in vitamins, minerals, trace elements and the like, and the change of water and electrolyte is monitored and timely supplemented and adjusted.

The wound surface is observed and nursed by the way that the wound dressing is collapsed, contracted and hardened, the tube shape exists, no accumulation exists in the night below the film, and the liquid drainage is carried out, so that the negative pressure drainage is smooth and effective. Closely observing the quantity and quality of the drainage liquid, and correctly recording, if a large amount of fresh blood is sucked out, considering whether the wound surface has active bleeding, reporting to a doctor in time, and performing corresponding correct treatment; the peripheral blood circulation of the affected limb is observed, the functional position of the affected limb is kept, the affected limb is padded up by 30 degrees by using a soft pillow, the antibiotic therapy is reasonably selected, the psychological nursing is not neglected in the anaerobic bacterium therapy, the patient is encouraged to breathe deeply, the patient drinks more water, the patient stands up and claps the back regularly, the bed is kept flat, dry and clean, the pressed part is massaged frequently, and the complications such as respiratory tract infection, urinary system infection, bedsore and the like are prevented.

The existing VSD drainage base material is made of medical foam PVA material, the pores are small, clogging is easily caused in the suction process, and the adopted suction pipe is a pipe with porous sides, so that the clogging phenomenon and the retention of purulence or other impurities can be further caused, and the related problems are urgently needed to be solved. In addition, after medical foam is placed in a sore, a multi-side-hole drainage tube needs to be led out from a healthy skin puncture hole outside the edge of the sore, and the sealing performance during negative pressure drainage is mainly guaranteed in this way, but larger and more sores are caused, inflammation is caused, and therefore, the problem is very necessary to be solved.

SUMMERY OF THE UTILITY MODEL

In view of the above, there is a need for an improved negative pressure drainage device which can effectively promote the healing of the sore opening, and at the same time, can prevent the puncture hole of healthy skin at the edge of the sore opening from leading out the drainage tube, thereby reducing the pain and the wound of the patient.

Furthermore, the dressing of the utility model is medical collagen sponge.

Furthermore, the part of the drainage tube in the dressing of the utility model is porous.

Furthermore, the skin patch of the utility model is flexible silica gel, and when in use, the skin patch can be tightly attached to healthy skin.

Furthermore, the periphery of the skin patch of the utility model is thinned.

Further, the dressing of the present invention has a pore diameter of at least 0.5 mm.

The utility model discloses following beneficial effect has:

1. the utility model discloses in, adopt medical collagen sponge as the dressing, medical collagen sponge adopts the collagen that the ox achilles tendon made after carrying out biological purification as the raw materials, for white spongy solid, through cobalt 60 radiation sterilization. The collagen sponge is suitable for filling surgical residual cavities, stanching the wound surface and promoting the wound surface to heal; the medical collagen sponge is applied as a dressing, and can be used as a medical material for temporarily protecting wounds, preventing pollution and promoting healing. Can be tightly attached to the wound surface, has good affinity, and can be uniformly and tightly adhered to the wound surface; can prevent loss of body fluid and moisture; resisting bacterial invasion and preventing infection; the exudate flowing out of the wound surface can be absorbed, the effusion between the dressing and the wound surface can not be caused, and the pain is relieved; the normal growth of granulation and epithelial tissues is maintained and promoted, the healing of the wound surface is promoted, and no scar is left; the material has certain mechanical strength, is soft and does not deform; air permeability, water vapor permeability, moisture retention and good biocompatibility.

2. The utility model discloses in, adopt flexible silica gel to do the skin subsides, and the skin subsides closely combine with skin, the periphery of skin subsides is cut thinly, and when using, the drainage tube can combine with the negative pressure bottle through the skin subsides, treats that the top of dressing covers transparent adhesive film can be fine and the airtight combination of skin subsides on the sore mouth, can not cause negative pressure gas leakage, also can avoid the drainage tube to stab the hole on healthy skin and the inflammation that causes, avoids increasing new sore mouth.
