Abstract
The utility model discloses a novel hemostasis valve which comprises a Ruhr connector, a Y-shaped connecting bridge, a bridge valve and a valve opening cover which are sequentially connected to form a channel. A high pressure valve for preventing blood from flowing out is arranged in the channel, a puncture rod is arranged on the valve opening cover, the puncture rod stretches into the bridge valve to right opposite to the high pressure valve, the diameter of the puncture rod is matched with the inner diameter of the high pressure valve, a spring is sleeved on the puncture rod, correspondingly a retaining wall matched with the spring is arranged in the bridge valve, one end of the spring is connected with the retaining wall, and the other end of the spring is connected with the valve opening cover. Therefore, a user presses the valve opening cover to enable the puncture rod to puncture in the high pressure valve to open the hemostasis valve, and the puncture rod automatically resets and breaks away from the high pressure valve under the effects of spring force after the valve opening cover is pressed again to close the hemostasis valve, and the novel hemostasis valve is simple in structure, convenient to operate and good in performance.
Description
Technical field
This utility model relates to a kind of haemostatic valve, relates in particular to a kind of novel haemostatic valve.
Background technology
Along with the continuous development of Medical Technology, advantage such as the interventional medicine technology is big with its diagnosis and treatment range, wound is little, easy, safe, effective, complication is few has become " new lover " of medical circle.When in carrying out blood vessel, getting involved; Need be with puncture needle through the shallow arteriovenous of puncture people's body surface; Get into the human blood circulatory system; Utilize special seal wire or other apparatus to insert again to deliver to the disease position of blood vessel to diagnose radiography, treatment, tissue sampling etc., and in this process in order to reduce the loss of blood in the blood vessel, need stop blood to flow out through haemostatic valve.Yet, present existing haemostatic valve complex structure, inconvenient operation, and performance also has much room for improvement.
The utility model content
To the deficiency of prior art, the purpose of this utility model is intended to provide a kind of simple in structure, easy to operate, novel haemostatic valve that performance is splendid
For realizing that above-mentioned purpose this utility model adopts following technical scheme:
A kind of novel haemostatic valve comprises successively linking to each other and forming female luer, Y shape Connection Block, the bridge valve of passage and open valve gap, is provided with in the passage to be used to prevent the effusive high pressure valve of blood; Open valve gap and be provided with puncturing lever, this puncturing lever stretch into the bridge valve and with high pressure valve over against, the internal diameter size of the diameter of puncturing lever and high pressure valve is adaptive; And; Be set with spring on the puncturing lever, corresponding, the retaining wall that matches with spring had in the bridge valve; One end of spring is connected with retaining wall, the other end with open valve gap and be connected.
As a kind of preferred version, said Y shape Connection Block is provided with the oblique arm that forms angle with passage.
As a kind of preferred version, the said outer race of opening valve gap is connected to the sign ring.
As a kind of preferred version; The outer race of said high pressure valve is connected to isolating cap, corresponding, said haemostatic valve further includes the nut that is threaded on Y shape Connection Block and the bridge valve; This nut matches with the bridge valve; When nut was screwed, the bridge valve shrank the compressing isolating cap, and the isolating cap repress is compeled high pressure valve.
A kind of novel haemostatic valve that this utility model is set forth; Its beneficial effect is: this product is through making puncturing lever thrust isolating cap to open haemostatic valve by pressing off valve gap; Under the spring force effect, automatically reset and break away from high pressure valve by pressing off behind the valve gap puncturing lever once more, thereby close haemostatic valve, it is simple in structure; Easy to operate, performance is splendid.

Fig. 1 is the configuration diagram of this utility model embodiment.
The drawing reference numeral explanation:
10, female luer 20, Y shape Connection Block
21, oblique arm 30, bridge valve 31, retaining wall 40, open valve gap 41, puncturing lever 42, sign ring 50, high pressure valve 60, spring 70, isolating cap 80, nut
The specific embodiment
Come this utility model is further described below in conjunction with accompanying drawing and specific embodiment.
Please with reference to shown in Figure 1, it has demonstrated the concrete structure of this utility model preferred embodiment, a kind of novel haemostatic valve; Comprise successively linking to each other and forming female luer 10, Y shape Connection Block 20, the bridge valve 30 of passage and open valve gap 40, be provided with in the passage and be used to prevent the effusive high pressure valve 50 of blood, open valve gap 40 and be provided with puncturing lever 41; This puncturing lever 41 stretch into bridge valve 30 and with high pressure valve 50 over against, the internal diameter size of the diameter of puncturing lever 41 and high pressure valve 50 is adaptive, and; Be set with spring 60 on the puncturing lever 41, corresponding, the retaining wall 31 that matches with spring 60 had in the bridge valve 30; One end of spring 60 is connected with retaining wall 31, the other end with open valve gap 40 and be connected.
And said Y shape Connection Block 20 is provided with the oblique arm 21 that forms angle with passage, can inject normal saline or other medicines to passage through oblique arm 21.
For more convenient people use, the said outer race of opening valve gap 40 is connected to sign ring 42, can clearly grasp the residing state of haemostatic valve through sign ring 42 people.
And in order further to improve the sealing property of passage to blood, the outer race of said high pressure valve 50 is connected to isolating cap 70; Corresponding; Said haemostatic valve further includes the nut 80 that is threaded on Y shape Connection Block 20 and the bridge valve 30, and this nut 80 matches with bridge valve 30, when nut 80 is screwed; Bridge valve 30 shrinks compressing isolating cap 70, and isolating cap 70 repress are compeled high pressure valve 50.
During use; This product is through making puncturing lever 41 compression springs 60 and thrust high pressure valve 50 and open haemostatic valve by pressing off valve gap 40, because the diameter of puncturing lever 41 is adaptive with the internal diameter size of high pressure valve 50, for further raising sealing; The nut 80 of also can screwing makes isolating cap 70 compressing high pressure valves 50; To fit closelyr with puncturing lever 41 behind high pressure valve 50 pressurizeds, this moment, sealing effectiveness be better, haemostatic valve open the back seal wire can be smoothly through by the passage of opening valve gap 40 to female luer 10.And when once more when pressing off valve gap 40, puncturing lever 41 will automatically reset under spring 60 elastic force effects, thereby breaks away from high pressure valve 50, and this moment, haemostatic valve was closed.This product structure is simple, and is easy to use, and performance is also splendid.
The above; It only is this utility model preferred embodiment; Be not that the technical scope of this utility model is done any restriction; So every technical spirit according to this utility model all still belongs in the scope of this utility model technical scheme any trickle modification, equivalent variations and modification that above embodiment did.
