Problems solved by technology

Because conventional blood purifiers are used in conventional medical environments, the requirements for fixing the blood pump cover are not high. Therefore, the magnetic attraction force of the above-mentioned fixing device is relatively small, and it can be opened with a light hand. It is easy to be opened due to the centrifugal force generated by the shaking, or the blood pump cover is opened due to the collision of people and objects caused by the shaking, so it cannot be fixed by magnetic attraction in this special environment

Embodiment 1

[0016] The invention provides a blood pump cover fixing device under rocking vibration field conditions, which is mainly composed of a compression seat 8, a spring 7, and a compression head 6. The compression seat 8 is a convex metal piece and is fixed to the blood pump Open the cover 3 on the side chassis panel 5. The convex metal part has a hollow cavity structure in the middle, with an opening at the top. The hollow cavity structure and the opening are used to nest the compression head, and the compression head 6 is an L-shaped Hook-shaped metal parts, the L-shaped hook-shaped metal parts are provided with barbs at their feet, put on the spring 7 and installed in the compression seat 8. The compression seat 8 is fixed on the chassis panel 5 by screws 9, and the compression head 6 can be drawn Pull to rotate.

[0017] When the barb is pinched and pulled upwards, the compression head 6 can be lifted and a downward pulling force is generated. After the compression head 6 is lifte...

Abstract

The invention discloses a fixing device for a blood pump cover under a rocking and vibrating outdoor battlefield condition. As an important component of a portable blood purification machine, a blood pump plays an important role in driving a blood circuit and the working state of the blood pump directly affects the normal operation of treatment. A blood pump cover is an important protecting device of the outside of the blood pump. After a blood tube is installed in the blood pump and the blood pump cover is fastened, blood pump equipment can be protected, sundries are avoided to enter into the inside of the blood pump, and the risk of the blood tube out of the blood pump is prevented simultaneously. The fixing device for the blood pump cover under the rocking and vibrating outdoor battlefield condition has the advantages of being capable of reinforcing the blood pump under a vibrating outdoor condition and preventing the blood pump cover from being loosed due to vibration.

Description

Technical field [0001] The invention relates to a fixing device for a blood pump cover, more specifically, to a fixing device for a blood pump cover under rocking vibration field conditions. Background technique [0002] The portable continuous blood purifier is a blood purifier that can be used in the field of rocking, shaking, and field conditions. Conventional blood purifiers can only be used in a hospital environment and the use environment is relatively stable. Therefore, the fixed requirements for each device of the equipment belong to Conventional requirements, because there will be no problems caused by vibration, so only conventional fixing devices are needed to meet the requirements. However, the portable continuous blood purification equipment is used in unconventional environments, such as extreme environments such as vibrations or battlefields. The treatment environment is very harsh and is in a swaying environment. Therefore, the fixing requirements for the various ...
