Description
Technical field
The invention belongs to medical instruments field, relate to a kind of disposable external hemostasis only liquid device.
Background technology
In clinical nursing activity, usually can run into patient because of a variety of causes such as change of illness state or post-operative complication and occur that wound continues the phenomenon of oozing of blood sepage, as drainage tube pulls out rear wound exudate, sepage etc. after central venous catheter tube drawing.Wound continues the sense of discomfort that sepage not only increases patient, weaken the treatment confidence of patient, also increase the workload of medical worker, even cause medical tangle, at present conventional clinically hemostasis, only liquid method is multifarious, but specifically effectively inexpensively again not to occur.Illustrate hemostasis conventional clinically at present, only liquid method:
1, more change dressings: be the most traditional be clinically at present also one of most popular method.Traditional dressing comprises the stocks such as gauze, cotton pad, binder.Mainly through changing wound dressing frequently, keep wound dry, until wound healing.Because wound oozing of blood, sepage time are not fixed, when the patient that is everlasting changes position obviously, and clinician because of workload large, fully occupied, can not accomplish to change dressings in time.The wound continuing sepage not only easily causes patient infection, patient is also made to have clammy, dirty sensation, wound dressing viscosity simultaneously due to drenched is poor, more easily come off, patient arbitrarily dare not change position, body is in stiff state, not only affects patient's rest and also easily pressure ulcer event occurs, and frequent replacing wound dressing increases medical personnel's workload and patient economy burden.
2, ostomy bag: the method by the liquid drainage that exosmoses in ostomy bag, can be avoided outer sepage to pollute patient's clothes and sheet, decrease the workload of medical personnel, allow patient feel relative comfort.But the method can't resolve the root problem of wound exudate, outer sepage can be oozed out at any time because patient changes position, and wound locates sepage state for a long time, causes wound not heal.Long sepage not only increases patients ' psychological burden and also easily causes patient infection.
3, liquid glue (ear brain glue): this medicine will use behind Kaifeng in time, not so can natural coagulation.For medical disposable material product, specification is comparatively large, but using dosage is few, and each needs several, and surplus is easily wasted, and expensive, does not enter medical insurance.This medicine, when sticky benefit wound, because be liquid structure, not easily controlled, is often adhered to surrounding skin, especially at a crease in the skin place, easily causes upper and lower skin adhesion not easily to separate.Concerning the patient of Cirrhosis with Intractable ascites, because of the sepage of puncture orifice persistence, when liquid glue does not also become solid completely, often diluted by ascites or oozed out along with ascites and run off, only liquid effect is undesirable.
4, rubber closure: be the little skill adopted clinically.Soft rubber plug is aimed at wound, then presses rubber closure top, at the time standby medico paper glue of rubber closure resilience, soft rubber plug is fixed, take off after about 48 hours, check wound healing situation.The method is simple and practical, successful, but shortcoming is also a lot.First, because the wound site of patient is had nothing in common with each other, the properly fixing just existing problems of rubber closure.Wound rubber closure for adjacent joints position is often not easily fixed, and sealing is poor, easily blood occurs, body fluid leaks outside.For often by the position arrived of rubbing, even if paper using glue is properly fixed, also easily there is rubber closure when patient inadvertently touches or changes position and be shifted or slippage, cause blood, body fluid leaks outside.Long-time paper using glue is repeatedly fixed, and easily causes patient skin impaired.Secondly, because rubber closure is transparent materials, the healing state of the wound that is invisible to the naked eye, rule of thumb can only take off rubber closure at 48 hours and check wound healing situation, then determines whether continual cure.Thus one, not only can not correctly judge wound healing situation, also may not be found because compressing for a long time causes periwound skin downright bad.Moreover rubber closure, for gathering materials on the spot, does not have strict disinfecting, easily causes wound infection.
Summary of the invention
The object of the invention is the deficiency overcoming prior art existence, a kind of disposable external hemostasis only liquid device is provided, be made up of the hollow circular cylinder of semicircular base, both ends open, one-way cock and the broad edge containing viscose, semicircular base is spherical tangent plane, cylindrical lower end is connected with the opening of semicircular base, cylindrical upper end open connects a broad edge containing viscose, one-way cock is arranged on cylindrical side, after the outside withdrawing air of syringe, this valve can be closed automatically, prevent air circulation, keep internal negative pressure state.This device shape is like the circular sunbonnet of broadside.One deck protection sheet is being posted containing in the broad edge of viscose.
Described device materials selects transparent latex or silica gel material.Whole device oxirane disinfection is packed.
The present invention has the following advantages: (1) selects transparent material can be clear that wound healing situation, determines treatment time according to wound healing degree.Also can observe wound and surrounding skin situation of change thereof simultaneously, avoid the generation of pressure ulcer or necrosis.Soft latex material suitable distortion can adapt to touching of human body, and volume is little facilitates patient self management.(2) one-way cock design can atmospheric pressure state at any time in adjusting device.Withdrawing air, is in negative pressure state in device, promotes the growth of blood capillary by forming ischaemia state, improves the oxygen content of wound local.Negative pressure on wound edge forms nature physics traction force simultaneously, and this strength can promote fibroblastic schizogamy, accelerates epidermis and creeps, accelerating wound.When withdrawing air, wound skin outwards draws in, wound closure, and liquid also no longer oozes out.(3) the attached waterproof of broad edge viscosity pad pasting can well with patient contact, even if also can well adhere at joint part, facilitate medical personnel to operate.The generation that waterproofing design can also avoid blood, body fluid leaks outside.The design of this broadside not only can guarantee that the fastness of pasting can also maintain the integrity of patient skin.(4) pack separately with oxirane disinfection, stopped to infect because the problem of device causes.(5) according to clinical common wound type, the device of difformity and specification can also be designed to.
