Abstract
The utility model relates to a hand blood pump with prevent reverse rotating -structure, including a blood pump, this blood pump is through a rotation axis connection crank, it is a coaxial fixed mounted ring flange in the axis of rotation, equipartition system has the sawtooth on the ring flange circumference, be provided with an electromagnetic attraction device with ring flange sawtooth corresponding position, this electromagnetic attraction device uses through a kayser board and the cooperation of ring flange sawtooth, this hand blood pump simple structure, the novel speed control switch is reasonable in design, can prevent effectively that staff reversion unintentionally from waveing, thereby avoid the backward flow of blood, improve security and reliability.
Description
Technical field
This utility model belongs to hand blood pump field, especially a kind of hand blood pump with anti-reverse rotational structure.
Background technology
Cardiac operation at present the most widely used cardiopulmonary bypass pump is roller pump.In order to ensure in unexpected power failure, and when reserve battery is used up, blood pump still can be made to rotate and to complete operation process.So each blood pump is provided with manual rocking handle, in order to during needs, blood pump is manually shaken, if but artificial shake direction shake and instead can produce blood backflow, likely cause life danger.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of hand blood pump with anti-reverse rotational structure is provided, this hand Blood pump structure is simple, design science reasonable, effectively can prevent the undesigned reverse shake of staff, thus avoid the backflow of blood, improve safety and reliability.
This utility model solves its technical problem and is achieved through the following technical solutions:
A kind of hand blood pump with anti-reverse rotational structure, comprise a blood pump, this blood pump connects crank by a turning cylinder, it is coaxially fixedly mounted with a ring flange on the rotating shaft, be shaped with sawtooth ring flange is circumferentially uniform, the position corresponding with ring flange sawtooth is provided with an electromagnetic suction device, and this electromagnetic suction device is used by a lug latch board and ring flange jigsaw fit.
And described lug latch board is iron plate.
Advantage of the present utility model and beneficial effect are:
Originally there is the hand blood pump of anti-reverse rotational structure, comprise a blood pump, this blood pump connects crank by a turning cylinder, it is coaxially fixedly mounted with a ring flange on the rotating shaft, be shaped with sawtooth ring flange is circumferentially uniform, the position corresponding with ring flange sawtooth is provided with an electromagnetic suction device, this electromagnetic suction device is used by a lug latch board and ring flange jigsaw fit, this hand Blood pump structure is simple, design science reasonable, effectively can prevent the undesigned reverse shake of staff, thus avoid the backflow of blood, improve safety and reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of hand blood pump with anti-reverse rotational structure, comprise a blood pump 6, this blood pump connects crank 1 by a turning cylinder 2, it is coaxially fixedly mounted with a ring flange 3 on the rotating shaft, be shaped with sawtooth ring flange is circumferentially uniform, the position corresponding with ring flange sawtooth is provided with an electromagnetic suction device 5, and this electromagnetic suction device is used with ring flange jigsaw fit by a lug latch board 4.Lug latch board is iron plate.
When having civil power or reserve battery is powered, this hand blood pump electromagnetic suction device adhesive, make lug latch board leave serrate ring flange, now blood pump can carry out the rotation of rotating according to the operation of operator.When civil power and reserve battery are all stopped power supply, electromagnetic suction device release tab jam plate, makes lug latch board stick into the serrate ring flange of band, will be stuck, blood pump can only be rotated according to predetermined positive direction owing to now rotating backward ring flange.This utility model solves when hand blood pump, the problem of reverse rotation, prevents blood from the problem refluxed in the heart, solves a problem of safe handling heart-lung machine.
