Description
Technical field
This utility model belongs to field of medical products, is specifically related to a kind of vacuum suction syringe.
Background technology
Vacuum extractor is applicable to variously need sucking-off human body liquid waste, decreasing pollution chance, Promotive union and functional rehabilitation.The principle of suction pump is very simple, is manufactured the negative pressure state of its sucking head exactly, is extruded by the material outside sucking head to sucking head, thus complete the effect of " attraction " by certain method.Be widely used in department of general surgery, at present the most frequently used is clinically disposable vacuum extractor or negative pressure ball, but find in real work that partial clinical demand can not meet: after part superficial tumor or extremity lumpectomy, estimate that drainage flow is few, if place above-mentioned drainage system in real work, the operation of medical personnel can be affected, cause operation inconvenience.Particularly when infant gets up activity, carry vacuum extractor inconvenience, and the conduit of vacuum extractor is longer, tractive easily causes drainage tube to be deviate from, and topples over metering drainage liquid every day and also easily causes cross infection; The special disposable vacuum extractor of another shortage infant gastrointestinal decompression on the market, connects the above-mentioned disposable vacuum extractor pressure of prior art and is difficult to control, often cause gastric bleeding because negative pressure is excessive in real work.
Domestic applications number be 2009201940606 utility model patent disclose a kind of Simple adjustable negative pressure injector, it comprises injection tube, and the front end of injection tube connects injection needle, and injection handle inserts in injection tube, and described injection handle is provided with locating hole.Pore size is set to just can pass pillowcase, only just need can make injection handle and injection tube relative localization with injection pillowcase through locating hole, formed in injection tube and maintain certain negative pressure of vacuum, for the purposes of drain or attraction, this device is simple to operate, effect safety and stability, whole device volume is little to be easy to carry and to be fixed on it patient.And production technology is simple, do not increase production cost and even can reduce the use of producing material, this simple refit to syringe adds the function of syringe, has widened its range of application, has made one-object-many-purposes, has not only economized on resources but also high-efficiency environment friendly.But this vacuum injector needs the syringe to having produced in batches in prior art to punch, and after punching, injection handle position is fixed by pillowcase, vacuum extractor negative pressure value is also fixed, namely the negative pressure value of this syringe only can be set as limited several negative pressure value of matching with the position in hole, cause the setting of negative pressure value only can several for wherein, the needs that operator arbitrarily set negative pressure value can not be met.
Domestic applications number be 20103472918 utility model patent disclose a kind of vacuum injector, comprise the syringe that lower end is provided with syringe needle adapter and the piston push rod be movably set in syringe, the maintaining body for making piston push rod be in negative pressure position is provided with between piston push rod and syringe, when piston push rod is in negative pressure position, syringe hypomere forms closed negative pressure cavity, syringe lateral wall is provided with the pressure release arm be communicated with negative pressure cavity, the Obstruct membrane that can keep off blood ventilation is provided with in pressure release arm, pressure release arm is provided with openable closing cap, it is simple that vacuum injector disclosed in it has structure, make vein or arterypuncture convenient, and it is dynamic to carry out judgement simultaneously, the advantages such as vein blood vessel.All there is the problem needing to improve existing syringe production technology in the syringe then in this syringe and previous technical scheme, can not improve on the basis of the technique of existing production syringe.
Utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of vacuum suction syringe, to overcome the defect of syringe pressure instability in prior art.
In order to reach above-mentioned utility model object and other objects, this utility model is achieved through the following technical solutions:
A kind of vacuum suction syringe, described vacuum suction syringe comprises syringe and pintle, described pintle comprises pintle flank, described pintle inserts in syringe, described vacuum suction syringe also comprises buckle, described buckle is provided with groove, and described groove and described pintle flank match, and the dismountable upper edge being located at described syringe of described buckle.
A kind of vacuum suction syringe is disclosed in this utility model, this vacuum suction syringe be the syringe of regular size in the prior art basis on improve, can not fix by under the effect of external force to make negative pressure cavity and negative pressure value, with automatic absorption drainage-fluid, its improvement is for setting up dismountable buckle, this buckle is provided with the groove wanting with pintle flank to coincide, in use, pull-out pintle, negative pressure cavity is formed in syringe, buckle is connected on described flank, and described buckle is located at the upper edge of syringe.Now, buckle is by the drag effect on edge on syringe, and there is frictional force between buckle and pintle flank, buckle can stop negative pressure in negative pressure cavity by pintle resorption, keep the stable of negative pressure in negative pressure cavity thus, under making the suction function continued in syringe, drainage-fluid to be absorbed can inspiration syringe smoothly.
In this utility model, the cross section of pintle flank is cross.It is regular size in prior art, but is not limited thereto kind of a specification.
The concrete pattern of buckle in this utility model is also unrestricted, as long as it containing the groove matched with pintle flank, and can be located at the upper edge of syringe, namely plays the effect of frictional resistance effect to pintle flank and fixing pintle flank.
Preferably, the lateral wall of described syringe is provided with containing mark.The setting of this containing mark accurately can calculate drainage flow, and under the effect continued in negative pressure, drainage flow number be convenient to observe, avoid nursing staff simultaneously and repeatedly topple over the cross infection problem that unnecessary drainage-fluid causes.
Preferably, described pintle is provided with negative pressure scale.Pintle is fixed on corresponding negative pressure scale to reach and to maintain the requirement of corresponding negative pressure to utilize buckle to say; And negative pressure arbitrarily can be set to required negative pressure value, namely negative pressure value is optional arbitrarily.
Preferably, the inwall of described groove is provided with rubber layer.Groove medial wall in this utility model is provided with rubber layer can increase the frictional force with pintle flank, the negative pressure value in more effective maintenance negative pressure cavity.
To sum up, its effect of the syringe of vacuum suction disclosed in this utility model is better than traditional negative pressure ball, and have no side effect and complication generation, shorten average stay, family numbers of patients and medical personnel's satisfaction rise.Compared with vacuum injector of the prior art, it has following beneficial effect:
1, make simple, cost is low, consumptive material is few, easy and simple to handle; Without the need to improving processing technique and the specification of syringe in prior art, only the buckle matched need produced.
2, it is from a scale, can accurately calculate drainage flow and negative pressure value, and drainage flow and negative pressure value are all easy to observe;
3, avoid nursing staff repeatedly to topple over drainage-fluid and cause cross infection;
4, easy to carry during activity, drainage tube not easily skids off, and in negative pressure cavity, negative pressure value is stablized, and is easy to the operation of medical personnel.
