When hole 2 41 is reached in sleeve 5, medical staff is manually pressed by inserted link 6.Slot 62 drives band 34 to move downward and be socketed in phase
On the permanent magnet 7 answered.Using the suction between permanent magnet 7 and iron plate 63, firmly band 34 is stuck on permanent magnet 7.
Sliding bar 9, fixed block 8 and holddown spring 10 are corresponding one by one, and sliding bar 9, fixed block 8 and holddown spring
10 number is at least one.At least one sliding bar 9 is corresponding at least one inserted link 6.In the original state, i.e. inserted link
6 with permanent magnet 7 when not blocking, inserted link 6 with side wall offset with one end of corresponding sliding bar 9.
Wherein, at least one fixed block 8 is corresponding at least one sliding bar 9.Each fixed block 8 is mounted on sleeve 5
On inner sidewall, and 9 sliding plug of sliding bar is on corresponding fixed block 8.At least one holddown spring 10 is fixed at least one
Block 8 is corresponding.One end of holddown spring 10 is connected with corresponding sliding bar 9, and the other end of holddown spring 10 is fixed with corresponding
Block 8 connects, and holddown spring 10 is slidably socketed on corresponding sliding bar 9.In this way during pushing inserted link 6, inserted link 6 is first
It offsets with corresponding sliding bar 9.Then sliding under the action of holddown spring 10 when sliding bar 9 is opposite with corresponding card slot 61
Lever 9 is blocked with corresponding card slot 61.The present embodiment one improves between inserted link 6 and corresponding permanent magnet 7 in this way
Clamping power, to ensure that the fixed stability of band 34.
Embodiment 2
With reference to Fig. 3-5, the present embodiment provides a kind of delay needles.It is detained needle to include extension tube 1, ring-shaped gasbag 11 and adjust
Device.
Wherein, annular groove is offered on the inner sidewall of extension tube 1 to be not shown in the figure.It is recessed that ring-shaped gasbag 11 is mounted on annular
In slot.And one layer of corrosion-resistant and safety and environmental protection material is coated on the outer wall of ring-shaped gasbag 11.The number of regulating device is at least
One, up to three.I.e. in extension tube 1 close to the lateral wall not device for installing and adjusting of patient's the back of the hand, avoid regulating device with
The contact of patient's the back of the hand.Each regulating device is respectively positioned in extension tube 1 for adjusting the flowing velocity of medical fluid in extension tube 1.Each
Regulating device includes sleeve 12, sliding panel 13, push rod 14 and snorkel 15.
As shown in Figure 4 and Figure 5, sleeve 12 assigns into extension tube 1.One end of sleeve 12 is located at the outside of extension tube 1.It is sliding
The inside of the sliding setting sleeve 12 of movable plate 13.One end of push rod 14 is connect with the upper surface of sliding panel 13, the other end of push rod 14
The top that sleeve 12 is stretched out in sliding reaches the outside of sleeve 12 and is located at the outside of extension tube 1.Push rod 14 and sleeve 12 are interference
Cooperation.One end of snorkel 15 penetrates through with the other end of corresponding sleeve 12 and connects, the other end and ring-shaped gasbag of snorkel 15
11 side wall penetrates through connection.
Air-flow in sleeve 12 is passed through snorkel using sliding panel 13 by pressing down on push rod 14 manually by the present embodiment
15 are input in ring-shaped gasbag 11, so that the internal diameter of ring-shaped gasbag 11 becomes smaller, to reduce the flowing speed of medical fluid in extension tube 1
It is dynamic.When improving the flowing quick-action of medical fluid in extension tube 1, push rod 14 is pulled up.Operation side in through this embodiment
Method, patient can voluntarily adjust the speed, and not need calling medical worker.The work of medical staff on the one hand can be reduced in this way
On the other hand amount also provides conveniently for patient.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
