Description
[technical field]
The present invention relates to a kind of medical apparatus and instruments, especially a kind of disposable, portable, can show and regulate the vacuum suction gathering system of negative pressure value in real time.
[background technology]
At present, the vacuum suction treatment is widely used clinically.It comprises drain of various operation postoperative fluid and negative pressure wound surface closed drainage technology.
Clinically, usually adopt wall vacuum suction or small-sized negative pressure pump attraction system to carry out the vacuum suction treatment: HC negative-pressure pipeline or micro-machine negative pressure pump produce continuous negative pressure suction, by barometer shunting and show vacuum magnitude, be connected with negative pressure collecting bag or receiving flask after being adjusted to treatment pressure; The other end of collecting bag or receiving flask and negative pressure drainage position join, and receive draining fluids.The negative regulation that these class methods produce, size can be regulated.
In addition, portable negative pressure device is also comparatively commonly used, and its negative pressure comes from the negative pressure that mechanically stretching produces.Concrete form mainly contains the negative pressure device of spring vacuum extractor and syringe repacking.The former produces negative pressure by spring compression back bounce stretching accordion sample plastic tank; The latter pulls out in the needle tubing of back by pintle machinery and produces negative pressure.This type of square law device volume is less, and the patient can carry, and is humanized.
But wall vacuum suction or small-sized negative pressure pump attraction system have limited patient's activity space owing to need be connected with power supply with central tube, have only the inpatient can accept this kind treatment.In addition, this vacuum suction system cost height (small-sized negative pressure pump is wanted about ten thousand yuan, hundred yuan of depressimeters), treatment environment and condition are also had relatively high expectations (need carry out in the ward), and this makes a large amount of out-patients can not obtain this negative pressure treatment.
Though the machinery negative pressure device is lightly portable, cheap.But the negative pressure instability that it provides more can not show pressure-reduction level, poor controllability.Occur the excessive problem of negative pressure clinically easily, cause to attract mouthful suction to cross the macrolesion surrounding tissue; Or the problem that negative pressure is too small even negative pressure disappears, cause the drain failure, cause hematoma, complication such as seroma even infection.The problems referred to above have limited portable vacuum suction and have further developed.

[specific embodiment]
Describe the specific embodiment of disposable portable visible negative-pressure adjusting, absorbing and collecting system of the present invention in detail below in conjunction with accompanying drawing.
Referring to accompanying drawing 1.
Disposable portable visible negative-pressure adjusting, absorbing of the present invention system comprises that pressure regulates, keeps and gathering-device, pressure-display device be connected and switching device three parts; Pressure is regulated, is kept with gathering-device and be made up of needle tubing 4, pintle 3; Pressure-display device comprises dropper bottle 11, syringe 10; Connection and switching device are made up of connection tube 5, flow regulator 6 and drainage tube 12.Pressure maintenance device is communicated with pressure-display device by connection tube 5, and on connection tube 5, be provided with flow regulator 6, another connection tube 5 is communicated with pressure-display device and drainage tube 12, needle tubing 4 is marked with the 20ml scale value and is provided with active card 2, pintle handle 1 is provided with ten bayonet sockets 13, dropper bottle 11 is connected with syringe 10 threeways, syringe 10 is marked with the negative pressure scale value, the latex balloon 8 that specific thicknesses and length are arranged at syringe 10 muzzles, and fixing with the silicon rubber cup 7 that the air filter membrane is housed, to prevent causing the pollution of air to drainage system because of the air bag cracking.
Embodiment 1: the adjusting of negative pressure.
1. pintle 3 is placed needle tubing 0ml position, open active card 2, open flow regulator 6; 12 of drainage tubes are connected patient's negative pressure treatment zone, and connection tube 5 connects negative pressure display device and negative pressure holdout device respectively, negative pressure display device and drainage tube 12.
2. extract pintle 3 gradually, make and produce negative pressure in the needle tubing 4.By connection tube 5, negative pressure is transmitted to the negative pressure display device, along with the negative pressure in the dropper bottle 11 increases, the pressure differential of latex balloon 8 both sides makes air bag 8 prolong along syringe 10, because of the elongation and the negative pressure value linear (know-why is seen notes) of air bag 8, when air bag 8 reaches the scale at requirement negative pressure numerical value place, close active card 2, pintle handle 1 is fixed at this moment, and negative pressure is regulated and finished.
Annotate: know-why of the present invention: latex balloon 8 inside and outside pressure change make that latex balloon 8 is flexible, and its stroke and air bag 8 external and internal pressure differences have linear relationship, and physical equation is derived as follows:
∵k×ΔL＝F＝ΔP×S
∴ΔP＝k×ΔL/S
K (coefficient of elasticity of latex balloon)
L (latex balloon length variations)
F (distraction force)
P (pressure differential that latex balloon is inside and outside)
S (latex balloon cross-sectional area)
Therefore, can calculate pressure-reduction level (Δ P) by flexible (Δ L) amount of latex balloon 8, and the corresponding negative pressure value commonly used of the specific elongation of air bag is marked on the syringe 9.
Embodiment 2: the keeping of the taking-up of drain liquid and negative pressure.
Drain liquid more needs changed in needle tubing 4, and perhaps the negative pressure deficiency be used when needing to increase negative pressure.
1. close flow regulator 6, make negative pressure system airtight.
2. take off needle tubing 4, and the record drainage flow.Open active card 2, be connected to connection tube 5 once more after releasing drain liquid in the needle tubing 4 or gas fully.
3. repeat step 1-2 among the embodiment 1 and the step 1-2 among the embodiment 2, when reaching negative pressure pilot balloon 8 and reach required pressure-reduction level scale, close fixedly pintle handle 1 of active card 2.
Simple and easy negative pressure display device in the native system also can connect distinct device separately, and indication is pressure-reduction level substantially.
