Abstract

The present invention provides a water-bag airproof CO2 air-bag skin expander. An airproof mini-bag is placed into gas tube end connected with expandable bag. Asepsis normal saline swaps out air from the mini-bag by mini-injector and needle head, then CO2 gas with constant pressure is injected into gas tube for expanding the expandable bag. The saline in airproof mini-bag can prevent CO2 in expandable bag overflowing after the needle head is pulled out, and the mini-bag film made by self-close material can prevent saline overflowing, accordingly, expandable state of the expandable bag can be holding.

Description

Water sac sealing carbon dioxide air bag skin dilator

The present invention is a kind of skin expansion medical apparatus and instruments, especially implants the subcutaneous medical apparatus and instruments that carries out skin expansion by the dioxide capsule of water sac sealing.

At present, after skin is because of wound or tumor, nevus cell nevus resection operation when damaged, contiguous normal skin is repaired damaged by expansion, can be received satisfied effect.Present known skin expansion method is by performing the operation in subcutaneous implantation silica gel expansion water pocket and injection kettle, after waiting for wound healing (needing 2 time-of-weeks approximately), by the volume of water filling increase capsule, extruding skin outwards protrudes, skin surface is long-pending to be increased, and forms unnecessary skin in long term (the 1-2 month) back.Utilize this part unnecessary normal skin, cover the skin injury after cicatrix, tumor and nevus cell nevus excise.Shortcoming is to need behind the kettle by skin repeated localised puncture water filling expansion in embedding water pocket and injection, and therefore the injection site infection, hematoma, the skin dilating sacculus that splits may occur and expose complication, and patient's misery is bigger.Outward expanders such as vacuum suction skin dilator no doubt need not operation, but can't be used for depression positions such as axillary fossa, webs, also are unsuitable for local skin and organize very tight positions such as scalp.

In order to overcome the deficiency of existing skin dilator, the invention provides a kind of dilator, dioxide capsule by water sac sealing is implanted subcutaneous, and begin injecting carbon dioxide gas immediately and carry out skin expansion expansion, be used in combination separately or with the negative pressure attraction type skin dilator and reach the skin expansion purpose, avoided carrying out repeatedly complication and the patient's discomfort that skin penetrating occurs.

The technical solution adopted for the present invention to solve the technical problems is: a kind of carbon dioxide expansion capsule of special band sealing water pocket, during use, after aseptic dilator is inserted subcutaneous tract, the fine needle head that fills the physiological saline solution microsyringe is thrust in the sealed bladder of dilator catheter tip, twitch syringe piston, physiological saline solution is injected microcapsule and discharges air in the capsule fully, continue inserting needle then, syringe needle is thrust the dilator catheter lumen, get rid of after the interior air of dilator injecting carbon dioxide gas, after reaching certain pressure, extract syringe needle fast, the sealing water pocket of band self sealss film keeps sealing to water, by water gas is kept sealing then.Utilize the pressure of gas to make the expansion of expansion capsule, and and then outwards push skin and subcutaneous tissue, skin is subjected to the outwards lasting tractive of active force of protrusion, the cell of skin and organize the irriate hypertrophy, form the unnecessary skin that surpasses the preceding area of expansion, be used further to repair other because of damaged wound surface of operation such as nevus cell nevuss.In addition, adopt this method to make skin to be expanded form local crowning, be convenient to adhering to of negative pressure attraction type skin dilator suction nozzle, both share and reach better expansion effect.Wherein dilator capsule and conduit are made by the medical silica-gel material, and the sealing microcapsule is then made by the silica gel material of self sealss character, is the aseptic disposable product, are packaged in the adaptive aseptic plastic cover envelope of profile, and be easy to use, helps preventing cross infection.

The beneficial effects of the utility model are that this dilator begins expansion immediately after implantation, need not to shorten the expansion time by skin repeated localised puncture water filling expansion, uses also easier.

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is the water sac sealing carbon dioxide air bag skin dilator structural representation

Fig. 2,3 is water sac sealing carbon dioxide air bag skin dilator implementation step and operation principle sketch map.

1 dilator, 1.1 expansion capsules, 1.11 expansion cyst walls, 1.12 expansion blister cavities, 1.2 airways, 1.21 inducing QI tube walls, 1.22 airway lumen, 1.3 sealing microcapsules, 1.31 microcapsule walls, 1.32 microcapsule chambeies, 2 syringes, 2.1 syringe needles, 2.2 needle tubings, 3 adjust blood pressure carbon dioxide air delivery devices, 3.1 joints, 3.2 filters, 3.3 airways, 3.4 air gauges, 3.5 pressure regulator valves, 3.6 steam vents are pressed table 3.8 valve 3.9 gas bombs for 3.7 bottles among the figure.

In Fig. 1,2, dilator (1) is divided into expansion capsule (1.1), airway (1.2) and sealing microcapsule (1.3) three parts, its expansion cyst wall (1.11) is made by the good silica gel material of histocompatibility with inducing QI tube wall (1.21), expansion blister cavities (1.12) communicates with airway lumen (1.22), airway (1.2) is the tubular structure of a side endcapped, cecum is sealing microcapsule (1.3), and microcapsule wall (1.31) is made up of the biocompatibility good material to the water self sealing action.

In Fig. 1,2,, general microsyringe (2) comprises syringe needle (2.1) and needle tubing (2.2) two parts.

In Fig. 1, adjust blood pressure carbon dioxide air delivery device (3) comprises joint (3.1), filter (3.2), airway (3.3), air gauge (3.4), pressure regulator valve (3.5), steam vent (3.6), bottle pressure table (3.7), valve (3.8) and gas bomb (3.9).

In Fig. 2,3 illustrated embodiments, the expansion capsule (1.1) of dilator (1) and airway (1.2) place subcutaneous after, (2) No. 4 half syringe needles of microsyringe (2.1) that fill physiological saline solution are thrust in the sealing microcapsule (1.3) of airway (1.2) endcapped, push-and-pull needle tubing (2.2) piston injects normal saline in the microcapsule (1.3) and discharges air in the microcapsule; After finishing, continue inserting needle syringe needle (22.1) is thrust from the airway chamber.Twitch needle tubing (2.2) piston, discharge air in the expansion capsule; Open the valve (3.8) on the carbon dioxide cylinder (3.9), unclamp pressure regulator valve (3.5); The joint (3.1) of adjust blood pressure carbon dioxide air delivery device (3) is connected with syringe needle (2.1); Carbon dioxide in the gas bomb (3.9) injects with syringe needle (2.1) through pressure regulator valve (3.5), airway (3.3), filter (3.2) and joint (3.1) and enters in the expansion capsule (1.1).Adjust pressure regulator valve (3.5) after air gauge (3.4) demonstrates required pressure, pull out syringe needle (2.1) fast, saline in the sealing microcapsule (1.3) prevents that the carbon dioxide of expanding in the capsule from overflowing, and prevent brinish overflowing, thereby make the expansion capsule keep expansion state by the microcapsule membrane of self-enclosed material preparation.
