Abstract
The utility model relates to an instrument that is arranged in skin transplantation operation to monitor application pressure, by the pressure sensing front end, differential pressure sensor and pressure display appearance are constituteed, as long as the pressure sensing front end that makes medical silicon rubber when wrapping distributes around transplanting skin properly, the pressure that the dressing was wrapped can be measured by differential pressure sensor, show pressure size through pressure display appearance, for medical personnel provide an effectual monitoring means in skin transplantation operation, it is very useful to improve the skin survival rate of transplanting.
Description
This utility model belongs to medical Instrument field, refers to especially a kind of cutify be sticked the instrument that pressure is monitored.
In the operation of burn and shaping patient cutify, what twine deposited band formation at last sticks pressure to the crucial influence of having survived of cutify, too tight or too loosely all can cause the failure of transplanting, at present main experience that relies on medical personnel and feel and adjusted in operation, perhaps judged still do not have a kind of simple and practical quantitative monitoring method so far according to signs such as the variations in temperature of blood downstream direction limbs and the colours of skin.
The purpose of this utility model is to provide a kind of cutify to stick pressure monitor, is beneficial to control the size that sticks pressure in the cutify operation, improves the survival rate of cutify.
The technical solution of the utility model is to be made of pressure-sensitive front end, pressure transducer and pressure display instrument three parts, stick the sensing element of pressure as monitoring with pressure transducer, to stick pressure by electronic circuit and change the signal of telecommunication into, the display panel of being made up of charactron shows the numerical value that sticks pressure at last; The pressure-sensitive front end is made by the medical grade silicon rubber material, is made up of the pressure-sensitive bubble and the pressure-sensitive sebific duct of middle water-filling, and inserts differential pressure pickup, also can directly use the pressure-sensitive sebific duct of water-filling as the pressure-sensitive front end without the pressure-sensitive bubble.With the pressure-sensitive front end suitably be laid on demand cutify around, when wrapping operation with pressure-sensitive front end and limbs one reinstate apply tape winding around, stick pressure and can reach differential pressure pickup, and then measured, show by pressure display instrument, can be medical personnel real-time data are provided when operation.
Now reaching embodiment in conjunction with the accompanying drawings specifies this utility model:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sketch map of the pressure-sensitive front end of this utility model;
Fig. 3 is the sketch map of the differential pressure pickup of this utility model;
Fig. 4 is the sketch map of the pressure display instrument of this utility model;
Fig. 5 is this utility model workflow schematic diagram.
As shown in Figure 1, 2, 3, this utility model is made of pressure-sensitive front end 1, differential pressure pickup 2 and pressure display instrument 3.Wherein, pressure-sensitive front end 1 connects pressure-sensitive sebific duct 12 by several pressure-sensitive bubbles 11 and forms, and pressure-sensitive front end 1 also can only be formed with a pressure-sensitive sebific duct 12, and they are by the medical grade silicon rubber manufacturing, and pressure-sensitive bubble 11 is the ovoid of hollow.With the pressure-sensitive of pressure-sensitive front end 1 steep the cutify 5 that is laid in behind 11 pressure-sensitive sebific ducts, 12 water-fillings around, be with 4 wrappings with applying.The pressure that sticks that wrapping forms reaches differential pressure pickup, shows its force value by pressure display instrument 3 at last.In practical operation, in the process with the water filling of whole pressure-sensitive front end, need to get rid of its air pocket, the port one 3 of pressure-sensitive front end 1 will be shut port one 3 at last as aerofluxus.For ease of operation,, do not draw among the figure in the threeway that port one 3 places can adorn a belt switch.The pressure-sensitive sebific duct 12 of pressure-sensitive front end 1 other end connects the interface 21 of differential pressure pickup 2, another interface 22 logical atmosphere of differential pressure pickup 2.
There is a presser sensor diaphragm 23 that the differential pressure pickup inner space is divided into two in the inside of differential pressure pickup 2, because interface 21,22 inserts different pressure respectively, the variation that the pressure drag electric bridge that the strain of presser sensor diaphragm 23 causes being provided with on the diaphragm has a resistance, in the present embodiment, the model of differential pressure pickup 2 is PT50, be fixed in the housing of pressure display instrument 3, its interface 21 stretches out the housing rear board of pressure display instrument 3, interface 22 is logical air interface, on the housing rear board, in Fig. 4, do not draw yet.The circuit input and output lead of differential pressure pickup 2 wiring boards direct and pressure display instrument 3 inside join.
As shown in Figure 4, the display panel of forming by charactron on the panel of pressure display instrument 3 31, display lamp 32, on and off switch 33, zero setting button 34 and unit switching button 35.Wiring board and differential pressure pickup 2 are contained in the inside of display instrument 3.
Fig. 5 is a workflow schematic diagram of the present utility model, utilizes pressure reduction P
1-P
0Make the presser sensor diaphragm of making by monocrystal silicon 23 produce strain, the pressure drag electric bridge is arranged on the diaphragm 23.The strain of presser sensor diaphragm 23 causes resistance variations Δ R, through the processing and amplifying Δ of electronic circuit, will stick pressure at last and directly be shown by pressure display instrument 3.
This utility model is simple in structure, and cost is low, but can make skin graft operation handle science, easy, effective more, and is very useful to improving skin graft survival rate.
