Description

Hand tremulous pulse compression apparatus

Technical field

This utility model belongs to medical instruments field, relates to a kind of haemostat, relates in particular to a kind of hand tremulous pulse compression apparatus, is used for the closed hemostasis of the external compressing of seldinger technique artery point of puncture.

Background technology

After femoral artery puncture carries out intervene operation,, have manually at present and push methods such as mechanical pressure and vascular suture the hemostasis method of femoral artery puncture point.Artificial pressing method commonly used strips arterial sheath after surgery, must very push point of puncture arduously about 20 minutes with hands by the doctor, use salt bag Pressur hemostatic then, one is loosening or press pressure is inhomogeneous will cause bleeding and hematoma slightly, and patient also needs the long period bed, increase patient's misery, so artificial pressing method is wasted time and energy and complication is more.The vascular suture method, though hemostasis is rapidly, complication is less, obviously increases patient's expense, clinical practice is difficult to popularize.

In the last few years, the worker of China's medical apparatus and instruments circle just solved femoral artery puncture position hemostatic problem, had carried out the research work of tremulous pulse compression apparatus, several haemostat of release, and its structure is mainly by pedestal, and the screw rod and the fixing band that are located in the pedestal are formed.But seldom select for use clinically, its reason mainly has the following disadvantages:

1, be difficult to grasp the compressing dynamics: directly by rotary screw, pressing plate is exerted pressure to point of puncture, operator are difficult to grasp the accuracy of compressing dynamics.2, steadiness is poor: pressure point is again the strong point, and the patient can cause haemostat crooked even overturning phenomenon to occur because of careless touching or physical activity, makes the hemostasis failure.3, fixed form instability: because of fixing band has certain elasticity, fix by being bonded at shank, skew appears in pressure point easily, causes and puts forth effort the inhomogeneous haemostat that makes and lose effect.4, security protection is poor: safe locking device is not set.

Summary of the invention

The sleeve that has female thread and outer alligator is installed in the hole at ∩ shape pedestal top, with the tooth bar interlock in the one skew back hole, hole, the tooth bar top is provided with an alignment pin, be provided with the trimming bolt that matches with its female thread in the sleeve, operating axis in the square hole of trimming bolt upper end is connected with handle by the sleeve upper end hole again, the pressing plate opening shaft that has a pressing plate cover is inserted in the circular hole of trimming bolt lower end and is interconnected, in the cross-drilled hole of ∩ shape pedestal top-portion apertures, be provided with the locking pin of return spring, and be connected with cross-drilled hole draw ring outward;

Three), fixed mechanism

It is by 1. hanging scroll, arcuate zone and hanging groove are the band joint of one, 2. the cingulum that has hanging scroll, 3. locker is formed, described locker, its outer bottom are provided with and with the hanging scroll that is connected of joint, are provided with in it to be used to block cingulum and locking wrench is the inner core of one, resetted by stage clip, the both sides that are positioned at locking wrench are provided with two locking slide blocks;

Be connected successively by at least 4 band joint head and the tail, the terminal cingulum that connects, cingulum penetrates locker and pins, with locker again embedding hang on the band joint, thereby connect into a band, again the band at two ends is saved embedding respectively and hang in the intermediary hanging groove in pedestal both sides, constitute fixed mechanism at last;

Four), bascule

Respectively connect a balance plate in two holes at ∩ shape pedestal lower ending opening place, two balance plates become 120 ° of angles.

Advantage of the present utility model and beneficial effect

This utility model has the following advantages and beneficial effect under the structure configuration of excellence:

Advantage: rational in infrastructure, modern design, easy to use, safe and reliable.

Beneficial effect:

1, hand tremulous pulse compression apparatus is a kind of hemostatic device of external wearing formula.Mutual relation according to hemostasis by compression principle, thigh portion fastening means and balanced action is taked the design of " ∩ " shape base construction, has guaranteed can not be out of shape when haemostat is stressed.

2, be arranged on the pressing plate at " ∩ " shape pedestal top and the balance plate that the pedestal opening place is provided with respectively, formed 3 stable contact surfaces shank.The hanging groove that pedestal two middle side parts are provided with embedding is respectively hung fixing band, make pressing plate and 2 balance plates be distributed in the fixing band both sides, thereby the stressed crooked and overturning of pressing plate in the time of can not causing hemostasis by compression makes haemostat in use remain balance, and has stability.

3, at pressing plate, after being with transparent cushion cover on the position of the continuous successively tape splicing joint of balance plate and head and the tail, the height that mm surplus in the of 10 is arranged, has the overhead system fixed form with shank fastening back formation, the overhead system fixed form makes haemostat and shank have only several contact surfaces, has both prevented that haemostat from occurring rotating or displacement at shank, can guarantee to utilize the overhead slit, space that forms with shank again, rehabilitation of patients is accelerated in the be more convenient for circulation of shank blood.

4, the mode of hand is neither lost the sensation that staff is pushed, can substitute staff again and push, be convenient to operator more and can accurately hold required applied pressure, and pressing plate and trimming bolt are the ball-type contact surfaces, thereby guarantee the stressed even of pressing plate, the skew of putting forth effort of pressure point can not occur.

5, fastening shank because adopt several band joint head and the tail successively embedding hang ways of connecting and fix, so this utility model haemostat is according to patient's shank thickness, band joint number can increase and decrease at any time, about being regardless of again, the patient of applicable different builds.

6, the operating position in this utility model is equipped with safety device, has improved the safety of using more.
