Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
As shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, the utility model provides a kind of liquid extraction apparatus for medical equipment, this device is made up of the rifle headstock 13, liquid extraction apparatus and rifle head drop device (14), and wherein the rifle headstock (13) is for putting rifle head (11); Whether liquid extraction apparatus comprises rifle head pick-up unit (rifle head detector tube (9), microswitch (8) or optocoupler etc.), come off for detecting disposable rifle head; Whether the galvanic circle be connected with rifle head, contact liquid level for detecting rifle head; Rifle head end has a hourglass head (12), which increases the sealing of this device, improves the imbibition degree of accuracy of this device; Rifle head drop device (14) comprises rifle head and automatically abandons buckle, uses rifle head for automatically abandoning.Rifle head detector tube (9) end is jagged, and this structure makes rifle head automatically abandon buckle to block rifle head (11) quickly and accurately and abandon.
In the utility model, two insulating coatings (3) are enclosed within rifle (1) successively, gun carriage 1 (2), gun carriage 2 (4) are enclosed within insulating coating (3) respectively, move up and down position detect catch (6) be screwed on gun carriage 1 (2), gun carriage 1 (2), gun carriage 2 (4) are screwed on slide block, rifle (1) and support insulate, be connected with circuit, for detecting liquid level; Microswitch (8) is screwed on microswitch support (7), microswitch support (7) is screwed on gun carriage 2 (4), spring (5) is enclosed within the rifle body of gun carriage 2 (4) below, and rifle head detector tube (9) is enclosed within the rifle body of spring (5) below.Stop screw is fixed on microswitch support (7) through the slotted hole on rifle head detector tube (9), and hourglass head (12) is positioned at the end of rifle head (11).Spring (5) withstands rifle head detector tube (9) when not installing rifle head, microswitch (8) is not contacted, when rifle head is installed, rifle head (11) and hourglass head (12) are combined closely, and upwards jack-up rifle head detector tube (9) makes microswitch (8) action.The rifle headstock (13) and rifle head automatically abandon buckle and are separately fixed on chassis (15).
