Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
By figure 1 to 5, including controlling axial sleeve pipe 1, sleeve pipe 1 left end is equipped with connecting block 2, the needle core 3 that direction and left end run through connecting block 2 about the dismantlement is connected with in the sleeve pipe 1, axial and the blood hole 4 that is located needle core 3 top about seting up on the sleeve pipe 1, set up the flow hole 5 coaxial and the intercommunication with blood hole 4 on the connecting block 2, the groove of stepping down 6 of axial and lower extreme and flow hole 5 intercommunication about seting down in the connecting block 2, the rotation is connected with upper and lower axial pivot 7 in the groove of stepping down 6, the coaxial impeller 8 that the front end inserted in the flow hole 5 that is equipped with on the pivot 7, the coaxial baffle 9 that is located the impeller 8 top that is equipped with in the groove of stepping down 6, pivot 7 upper end run through connecting block 2 and be equipped with about the pointer 10 of direction.
In order to facilitate the medical staff to observe whether the cannula 1 deviates, the clapboard 9 is provided with a torsion spring 11 connected with the rotating shaft 7.
In order to facilitate observation of medical staff, the upper end of the connecting block 2 is provided with an annular groove 12 which is positioned on the left side of the pointer 10 and in the up-down direction, and the upper end of the connecting block 2 is provided with a baffle 13 which is positioned behind the pointer 10 and in the front-back direction.
In order to facilitate the operation of medical staff, the left end of the needle core 3 is coaxially provided with a top block 14, the left end of the top block 14 is provided with a left-right axial pull rod 15, and the front end and the rear end of the connecting block 2 are respectively provided with a pressure wing 16.
In order to avoid the pointer 10 from being touched by mistake, the upper end of the connecting block 2 is provided with a protective cover 17, and the pointer 10, the annular groove 12 and the baffle 13 are all positioned in the protective cover 17.
In order to prevent the sleeve 1 and the needle core 3 from being polluted, a dust-proof pipe 18 which is axially arranged at the left and the right and is opened towards the left is detachably connected on the outer edge surface of the sleeve 1.
The utility model discloses when using, nook closing member 3 right-hand member surpasss sleeve pipe 1 one section distance, medical personnel take off dustproof pipe 18, make connecting block 2 upwards incline 45 degrees and nook closing member 3 naked part aim at the artery blood vessel of patient's arm, medical personnel hold the pressure wing 16 of the left and right sides respectively and promote pull rod 15 to the lower right side this moment, pull rod 15 drives nook closing member 3 through kicking block 14 and moves to the lower right side, nook closing member 3 drives sleeve pipe 1 through connecting block 2 and moves to the lower right side, after promoting pull rod 15 a distance to the lower right side, the right-hand member of nook closing member 3 and sleeve pipe 1 all pierces patient's skin, it does not change or the swing angle is less to observe the pointer 10 orientation this moment, show that sleeve pipe 1 has not yet got into in the artery blood vessel, continue to promote pull rod 15 to the lower right side this moment, thereby drive nook closing member 3 and sleeve pipe 1's right side below and move;
after moving for a certain distance, if the sleeve 1 is positioned in an arterial blood vessel at the moment, because the blood pressure of the arterial blood is large, the blood in the arterial blood vessel is squeezed into the blood hole 4, after the blood flows for a certain distance, the blood drives the impeller 8 to rotate clockwise, the impeller 8 drives the pointer 10 to rotate clockwise through the rotating shaft 7, the rotating shaft 7 drives the torsion spring 11 to rotate clockwise while rotating clockwise, so that the torsion spring 11 has anticlockwise torsion, after the rotation for a certain angle, the pointer 10 is changed from the left-right direction to the front-back direction, and the pointer 10 is contacted with the baffle 13, and at the moment, the right end of the sleeve 1 can be judged to be positioned in the arterial blood vessel;
when the medical staff pushes the blood to the right lower side for a too long distance, the sleeve 1 can be in the artery vascular tube for a short time, at the moment, the arterial blood pressure is greatly squeezed into the blood hole 4, the impeller 8 drives the rotating shaft 7 to rotate clockwise, so that the pointer 10 is driven to rotate clockwise, after the pointer 10 rotates for a certain angle, the left and right directions are changed into the front and back directions, the rotating shaft 7 drives the torsion spring 11 to rotate clockwise while rotating clockwise, so that the torsion spring 11 has anticlockwise torsion, at the moment, the ejector block 14 is continuously pushed to the right lower side, so that the sleeve 1 and the needle core 3 are driven to continuously move to the right lower side, after the sleeve 1 and the needle core 3 move for a certain distance, the right ends of the sleeve 1 and the needle core 3 puncture the artery vascular tube and are positioned outside the back wall of the blood, at the moment, the blood pressure in the blood hole 4 is small, and the pointer 10 is driven to rotate anticlockwise through the rotating shaft 7 due to the anticlockwise torsion of the torsion spring 11, the pointer 10 is far away from the baffle 13, at this time, the right end of the sleeve 1 and the needle core 3 can be considered to prick the back wall of the arterial blood vessel, at this time, the pressing wing 16 is pulled towards the left upper side to drive the sleeve 1 to retreat for a certain distance, when the pointer 10 changes to the front-back direction again and contacts with the baffle 13, the pressing wing 16 is stopped being pulled, and the right end of the sleeve 1 can be judged to be positioned in the arterial blood vessel;
when judging that sleeve pipe 1 is located arterial blood vessel, medical personnel make sleeve pipe 1 be in the horizontality after 45 degrees connecting blocks 2 of downward sloping, and medical personnel press down the pressure wing 16 this moment, keep connecting blocks 2 and patient's limbs fixed, pull rod 15 left this moment, pull rod 15 drives nook closing member 3 through kicking block 14 and moves right, and after moving a distance, nook closing member 3 keeps away from sleeve pipe 1, and the sleeve pipe 1 is promoted right this moment, makes sleeve pipe 1 right-hand member be located arterial blood vessel, and it can to block up and fix sleeve pipe 1.
Compared with the prior art, the beneficial effects of the utility model are that: sleeve pipe, connecting block, nook closing member, blood hole, impeller, pivot, pointer etc. that are equipped with, the medical personnel of can being convenient for confirm the position relation between sleeve pipe and the artery blood vessel through the direction of pointer to judge whether the sleeve pipe is located artery blood vessel, alleviateed medical personnel's work load, reduced the secondary injury that causes the patient, the pressure wing that is equipped with, kicking block, pull rod, the medical personnel's operation of can being convenient for, the dust tube, medical personnel of can being convenient for avoid making nook closing member and sleeve pipe receive the pollution, this simple structure, the design is novel, convenient to use, the practicality is strong.
