Circle inner ring is provided with water-swellable material layer, and the pressure measurement interface being connect with manograph, the pressure measurement interface are provided on connector sleeve
Between sealing ring and drainage tube, pressure measurement interface is connected with connector sleeve, and needle core head end and tail end are respectively arranged with the first blood back
Hole and the second blood back hole, the first blood back hole are in drainage tube and close to the head end of drainage tube, and the first blood back hole is led to by blood back
Road is connected with the second blood back hole.
Further, the needle core extends the outer 2-3cm of drainage tube.
Further, it is provided with valve in the pressure measurement interface.
Further, the piston is slidably connected with syringe sealing.
Further, syringe, connector sleeve and drainage tube are made of polyurethane material.
The beneficial effects of the utility model：The utility model discloses a kind of anti-hemorrhage arterial safety puncture pressure measuring needle, packets
Drainage tube and syringe are included, the drainage tube is connected by connector sleeve with syringe, and piston, the piston one are provided in the syringe
Side is provided with needle core, is provided with main spring between piston and syringe inner wall, and piston ridge offers open slot, at the open slot
Spool is provided with, the spool is connect by auxiliary spring with opening trench bottom, and the barrel sidewall offers through-hole, the through-hole
Place is provided with button, and the spool stretches into through-hole and button contacts, and sealing ring, the sealing ring are provided in the connector sleeve
Inner ring is provided with water-swellable material layer, is provided with the pressure measurement interface being connect with manograph on connector sleeve, at the pressure measurement interface
Between sealing ring and drainage tube, pressure measurement interface is connected with connector sleeve.The anti-hemorrhage arterial safety puncture pressure measuring needle of the structure, no
It is only avoided that when needle core retracts and stabs operating personnel, and be avoided that blood sprinkling and cause working face and operator front dirty
Dye.
Description of the drawings
The utility model is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The utility model is described in detail below with reference to attached drawing, as shown in Figure 1：The utility model provides one kind
Anti- hemorrhage arterial safety puncture pressure measuring needle, including drainage tube 1 and syringe 2, the drainage tube is connected by connector sleeve 3 with syringe,
Piston 4 is provided in the syringe, the piston is slidably connected with syringe sealing, and the piston side is provided with needle core 5, described
Needle core extends the outer 2-3cm of drainage tube, and the head end and tail end of needle core are closed, and main spring is provided between piston and syringe inner wall
6, during original state, main spring is in compressive state, and piston ridge offers open slot 7, spool is provided at the open slot
8, the spool is connect by auxiliary spring 9 with opening trench bottom, and the barrel sidewall offers through-hole 10, the through hole setting
There is a button 11, the spool stretches into through-hole and button contacts, is provided with sealing ring 12 in the connector sleeve, in the sealing ring
Circle is provided with water-swellable material layer 13, and the pressure measurement interface 14 being connect with manograph, the pressure measurement interface are provided on connector sleeve
Between sealing ring and drainage tube, pressure measurement interface is connected with connector sleeve, and valve 15 is provided in the pressure measurement interface, and valve is used
In the connection of control connector sleeve and manograph, to realize the controllability of invasive monitoring of blood pressure, needle core head end and tail end are set respectively
