Description

Negative pressure sealing drainage dressing structure

Technical Field

The utility model relates to a medical instrument, especially negative pressure seals drainage dressing structure.

Background

The negative pressure sealing drainage dressing seals the wound by pasting and constructs a structure for the drainage of negative pressure equipment, so that the effusion of the wound can be gradually reduced, thereby being beneficial to treatment and rehabilitation.

The defects of the prior art are as follows: the negative pressure sealing drainage dressing is usually a disposable article, so that the negative pressure sealing drainage dressing is not allowed to be uncovered for other treatment of the wound surface before one negative pressure treatment is finished in order to avoid external germs from contacting the wound surface again; for example, the sampling of test samples of wound effusion cannot be performed, and the administration of drugs for promoting wound healing cannot be performed.

Disclosure of Invention

The utility model provides a drainage dressing is sealed to negative pressure that can still can carry out surface of a wound and handle after drainage dressing laminating surface of a wound is sealed to negative pressure.

The technical scheme of the utility model is that:

drainage dressing structure is sealed to negative pressure, its characterized in that: it includes drainage dish, negative pressure pipe, porous silica gel and control tube, the drainage dish is a rubber dish, drainage dish top intercommunication has negative pressure pipe and control tube, and wherein the control tube is the stereoplasm plastic tubing, the control tube intussuseption is filled with the sealed piece of rubber, and its benefit lies in: when the medicine is needed to be taken in the drainage plate, a small-dose sterilized injector can be used for puncturing the rubber sealing block to inject a small amount of medicine into the drainage plate; use the small dose syringe after the disinfection to pierce through rubber seal block and extract a small amount of wound surface hydrops in to the drainage dish when needing the sample, the terminal surface is provided with porous baffle under the drainage dish, the terminal surface central authorities bonding has porous silica gel under the porous baffle, terminal surface just is provided with first cyclic annular adhesive tape around the periphery of porous silica gel under the porous baffle.

Further, negative pressure pipe lower extreme intercommunication has the branch pipe, be provided with a plurality of through-holes on the pipe wall of branch pipe, the branch pipe is located the drainage dish for the negative pressure drainage can be more even correspond the surface of a wound.

Further, the porous baffle is made of latex, the porous baffle and the porous silica gel are uniformly provided with micropores with the pore diameter of 1 mm (in a natural state, namely, the porous baffle and the porous silica gel are not in a stretching or compressing state at the moment), and the micropores on the porous baffle and the porous silica gel are arranged in a one-to-one correspondence manner. The silicone gel has good affinity to human body, does not produce large stimulation even contacting wound surface, but has certain viscosity, so the porous baffle is used for separating the porous baffle from structures such as a negative pressure pipe, a branch pipe, a drainage disk and the like.

Further, a second annular rubberized fabric is arranged on the periphery of the drainage disk. For further securing the structure.

Furthermore, the first annular adhesive tape and the lower end face of the porous silica gel are bonded with a first release paper, and the lower end face of the second annular adhesive tape is bonded with a second release paper, so that impurities and dust are prevented from being contaminated before use.

Further, the tops of the negative pressure pipe and the operating pipe are provided with removable protective caps to prevent dust from adhering before use.

The utility model has the advantages that: the negative pressure tube does not directly contact the wound surface, so that the stimulation of negative pressure to the wound surface is reduced; the porous silica gel is contacted with the wound surface but does not influence the liquid secreted by the wound surface; the liquid secreted by the wound surface can be sampled through the operation tube, and the wound surface can also be used for medicine.
