Bar 2 is oppressed, is threadedly coupled in screw hole on substrate 1, the rotation by oppressing bar 2 makes to oppress bar relative to substrate 1 moves up and down, to adjust the pressure being applied on blood outlet.The lower end of compressing bar exposes to the following table of the substrate 1 Blood outlet hemostasis is oppressed for contradicting in hemostatic port position in face；The upper end of compressing bar exposes to the upper surface of the substrate, To facilitate the lower end for adjusting the compressing bar to expose to the height of the substrate, to change the pressure being applied in hemostatic port Power.

The lower end surface for oppressing bar 2 is equipped with pressure sensor 8, the pressure for being applied to patient hemostasis position for incuding compressing bar Power.

Actuator 3, the present embodiment are nut, and actuator 3 limits on substrate 1 with being able to rotate, and are threaded in compressing bar 2 On, when 3 original place of actuator rotates, driving compressing bar 2 is moved up and down.The lateral wall of actuator 3 is divided into upper and lower two parts, top For smooth periphery, lower part is equipped with multiple first teeth 31 along the circumferential direction of lateral wall；It is also set on the lateral wall of actuator 3 There is card slot 33, card slot 33 is located at the lower position of actuator；Limiting slot 32 is additionally provided on actuator 3, limiting slot 32 is located at driving The upper position of part 3.

Casing 4, positioning on substrate 1, and are set in outside actuator 3 and compressing bar 2；

End cap 5 can move up and down under external force relative to casing 4；Including end casing 52 and it is connected on end casing 52 Connector sleeve 53；Connector sleeve 53 can be slidably set in casing 4.

End casing 52 is circular plate structure, has inner cavity 55, controls chip 9 and buzzer 10 is accommodated in inner cavity 55, The button cell 91 powered to the buzzer 10 and control chip 9 is additionally provided in inner cavity 55.Pressure sensor 8, buzzer 10 Equal electric signal connection control chip 9.End casing 52 is equipped with the through-hole 56 of connection inner cavity 55, to facilitate alarm sound to spread out of.

There is the second tooth 51 that can be meshed with the first tooth 31 on the inner sidewall of connector sleeve；First tooth and in the present embodiment Two teeth are vertically arranged, in order to moving up and down for connector sleeve.When second tooth 51 is meshed with the first tooth 31, end cap 5 is driven Connect actuator 3.

Elastic buckle (not shown) compatible with the card slot 33 on actuator is additionally provided on the inner sidewall of connector sleeve； Elastic buckle can select as needed it is in the prior art any one；When end cap moves down and is drivingly connected actuator 4, elastic card Button snaps onto card slot 33, for connector sleeve and actuator axial limiting.

Elastic component 6 has end cap and moves up, is detached from the trend being drivingly connected with actuator, and the present embodiment uses spring, It can according to need and select other elastic components, be arranged between connector sleeve 53 and substrate 1, for convenience of the rotation of connector sleeve, this reality Applying example will make spring setting between substrate 1 and support ring flat-plate 13, and support ring flat-plate 13 is set in outside nut, and connector sleeve 53 can be opposite It is rotated in support ring flat-plate 13.

End cap 5 is detached from after resetting to release with, the second tooth and engage with the first tooth.

Locating part 7 is arranged between casing 4 and end cap 5, after the second tooth moves up disengaging and the first tooth engagement, for hindering Not-go-end lid 5 moves down under external force.In the present embodiment, locating part 7 is the pull rod with handle, is pulled with facilitating；On casing 4 Equipped with the first limit hole 41, connector sleeve 53 is equipped with the second limit hole 54, and actuator 3 is equipped with limiting slot 32；It is de- in connector sleeve After the drive connection with actuator, i.e., when the top of the second tooth polar driving part on connector sleeve, pull rod is inserted into first In limit hole 41, the second limit hole 54 and limiting slot 32, axial upper limit connector sleeve and actuator.

When using the haemostat, haemostat is first bonded to patient on hand with bandage, the lower end surface for oppressing bar is aligned out Blood mouth, extracts locating part, and connector sleeve can move up and down under external force relative to actuator at this time；End casing is pushed, on connector sleeve Gap of second tooth between the first tooth glide, driving support ring flat-plate moves down, compressed spring；When Elastic buckle snaps onto card slot When interior, limitation connector sleeve is moved axially relative to actuator；Rotary end cover, actuator original place under the action of connector sleeve rotate, Driving compressing bar axial movement, to change the power being applied in hemostatic port.

After adjusting, pull-up end cap, Elastic buckle compression compression are deviate from, end cap is in spring out of card slot slightly Reset is moved up under effect；When end cap no longer moves, locating part is inserted into the first limited block, the second limit hole and limiting slot Interior, end cap is limited by locating part, cannot be moved axially, and operation of the Non-medical-staff to the haemostat is avoided.

In the haemostat use process, pressure sensor real-time monitoring compressing bar lower end surface is applied to the pressure of hemostatic port position Power controls chip controls buzzer warning when the pressure monitored exceeds setting value, and medical staff is reminded to handle in time.
