Example Embodiment

[0015] Example 1

[0016] Referring to Figures 1-3, the present invention consists of a screw rod 1, a nut clutch seat 2, a swing frame 3, a support rod 4, a positioning pin 5, a push rod sheath 6, a push head 7, a push head sheath 8, a plunger 9, Sleeve 10, swing rod 11, push rod 12, clamp seat 13, frame 14, syringe push rod 15, push piece card slot 16, push piece 17, switch spring 18, safety pin 19, swing block 20, compression spring 21, The tension spring 22, the opening and closing nut 23, the sliding sleeve 24, the guide sliding rod 25, the sensing element 26, the sliding seat 27, the contact 28, and the sliding groove 29 are composed. The two guide sliding rods 25 are fastened on the frame 14. The two sliding guide rods 25 respectively pass through the sliding groove 29 on the sliding sleeve 24 and the sliding seat 27. The sliding sleeve 24 is fixed on the sliding seat 27. The sliding sleeve 24 and the guide sliding rod 25 are in a dynamic fit, and the sliding seat 27 can Th...

[0017] Example 2

[0018] The transmission mode of the present invention is as follows:

[0019] Refer to Figures 1-3, (1) The opening and closing nut 23 is separated from the screw rod 1 and the installation action: pinch the pendulum block 20 and the pusher sheath 8, the compression spring 21 is in the compressed state, the pendulum member rotates a certain angle, opening and closing The nut 23 is separated from the screw rod 1, the contact 28 pushes the swing frame 3 to rotate at a certain angle with the two positioning pins 5 as the axis, and the sensor element 26 converts the swing of the swing frame 3 into a potential signal and transmits it to the electrical signal processing system. The tension spring 22 is in a stretched state, the elastic force of the toggle spring 18 is released, the safety pin 19 is ejected under the elastic force of the toggle spring 18, the relative position of the pendulum member and the push rod member are locked, and the pendulum member and the pu...

[0021] Example 3

[0022] The working mode of the present invention is as follows:

[0023] 1. The relative position of the pendulum member and the push rod member is locked: the position relationship between the safety pin 19 and the pendulum block 20 in the locked state of the relative position of the pendulum member and the push rod member, see Figure 4 , Figure 5 . In the locked state of the relative position of the pendulum member and the push rod member, if the pump is started, the alarm system will issue an alarm signal; in the state of the relative position of the pendulum member and the push rod member are locked, the pendulum member and the push rod member are as a whole It can be freely translated in the longitudinal direction to facilitate the insertion of the push piece 17 into the push piece card slot 16.

[0024] 2. The relative position of the pendulum member and the push rod member is unlocked: the position relationship between the safety pin 19 and the pendulum...

Abstract

An alarm and drive device for the incorrect installation of push rod in injector is composed of leading screw, nut holder, rocker, bearing rod, locating pin, protecting sleeves of push rod and push head, sleeve, pendulum rod, push rod, push head, clamp, machine frame, etc.

Description

technical field [0001] The invention belongs to the field of medical devices and relates to an incorrectly installed syringe push rod of a micro-injection pump and an alarm transmission device. Background technique [0002] None of the existing micro-injection pumps has an alarm function for incorrect installation of the syringe push rod. Some medical personnel are not familiar with the operation of the micro-injection pump or because of negligence, it often happens that the push piece at the end of the syringe push rod is not snapped into the push piece slot and then press the start button. The siphon phenomenon is easy to occur. Due to the air pressure difference, the syringe push rod will self-propel or the patient's blood will flow backwards, which greatly increases the risk of micro-injection and even causes medical accidents. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide an alarm...
