Example Embodiment

[0033] The following is attached Figure 2-8 The specific implementation of the present invention will be described in detail:

[0034] A quick fixing and unlocking mechanism for a blood pump, which includes:

[0035] Pump head 1;

[0036] A motor, which has a motor body 9 and a motor upper cover 8. The motor upper cover 8 is equipped with a pump head positioning ring 2;

[0037] The pump head 1 has a flange part that fits with the pump head positioning ring 2. The flange part is provided with a number of grooves, and the flange part is also provided with a number of locking grooves;

[0038] The pump head positioning ring 2 is provided with a number of buckles corresponding to the grooves, and the pump head positioning ring 2 is provided with a number of locks 6 corresponding to the locking grooves, and the locks 6 pass through the first elastic element 7 Realize reciprocating motion;

[0039] When the pump head 1 needs to be quickly fixed, the groove of the pump head 1 is aligned wit...

Abstract

The invention relates to the technical field of biomedical treatment, and in particular relates to a rapid fixing and unlocking mechanism of a blood pump, which can be applied to the blood pump, for example, of an in-vitro ventricle circulatory auxiliary system. When a pump head (1) needs to be fixed, grooves of the pump head (1) align at clamping buckles of a pump head positioning ring (2), afterthe pump head (1) is mounted in the pump head positioning ring (2) along the axial direction of the pump head (1), the pump head (1) is rotated for a certain angle, so that lock buckles (6) are clamped in lock buckle clamping grooves, and then the rapid fixing of the pump head (1) is completed; when the pump head (1) needs to be unlocked, an unlocking operation element (3) is operated, the unlocking operation element (3) drives a lock latch (4) to move, due to the irregular surface of the lock latch (4), the lock buckles (6) generate displacement and then are separated from the lock buckle clamping grooves, the pump head (1) is rotated till the grooves of the pump head (1) align at the clamping buckles of the pump head positioning ring (2), and then the rapid unlocking of the pump head (1) is completed.

Description

technical field [0001] The invention relates to the field of biomedical technology, in particular to a fast fixing and unlocking mechanism of a blood pump, which can be applied to blood pumps of an extracorporeal ventricular circulation assist system, for example. Background technique [0002] The blood pump of the Extracorporeal Ventricular Assistance System consists of two parts, the pump head and the driving motor. The pump head is a one-time use consumable, which needs to be connected and fixed with the motor during use, and unlocked and taken out after use. Fixing and unlocking scheme of the existing pump head, as attached figure 1 As shown, it is generally fixed axially by a buckle, and is fixed radially by using a locking screw. [0003] Such a fixing method has the following disadvantages: ① When fixing and unlocking the pump head, the operation of screwing is required, which is relatively cumbersome and time-consuming. ②It is difficult to grasp the force of screwi...
