Description

EXPANSION SHAFT TYPE MEDICAL INSTRUMENT WASHER

BACKGROUND

Technical Field

The present invention relates to the technical field of medical devices, and in particular to an expansion shaft type medical instrument washer.

Related Art

Most of medical test tubes are made of glass, and have relatively deep inner cavities. Existing cleaning devices which use the principle of cooking and water rushing are easy to clean. Usually after the medical test tubes are washed with a machine, it is necessary to manually scrub the medical test tubes again with a test tube brush. Artificial brushing is inefficient because it can only brush the inner cavity of each test tube, and it can also cause secondary pollution to the outer wall of the test tube.

The existing washer uses a motor to drive the test tube brush to rotate, which reduces the labor intensity of brushing the test tube to a certain degree, but still cannot scrub the outer wall of the test tube. Because the test tube brush rotates with water, there will be a lot of splashing water droplets during work, the working environment is harsh, and the impact on the electrical equipment is great.

Against the aforementioned shortcomings in the prior art, the objective of the present invention is to provide an expansion shaft type medical instrument washer.

In order to achieve the aforementioned objective, the following technical solution is adopted according to the present invention:

The expansion shaft type medical instrument washer including a test tube brush formed by a brush rod and bristles planted on the brush rod, one end of the brush rod is rotatably mounted on a bracket, the brush rod is in driven connection with a driving motor, and the brush rod is a columnar rod; a plurality of arc-shaped elastic pieces are symmetrically arranged on the outer surface of the brush rod, and the two ends of each arc-shaped elastic piece are fixedly connected to the brush rod; in addition, sliding rails are parallel to the brush rod, sliding blocks are mounted in the sliding rails and fixedly connected with wheel axles which are perpendicular to the sliding rails, and balance wheels are mounted at the two ends of the wheel axles; the sliding blocks each are fixedly connected with a nut sleeve and a Y-shaped roll shaft, brush rolls are mounted on the roll shaft, a screw is sleeved in the nut sleeve and is parallel to the sliding rail, and the screw is in driven connection with the driving motor.

Preferably, a transmission box is parallel to the bracket, the driving motor is fixedly mounted in a space between the transmission box and the bracket; the brush rod is inserted and mounted on the transmission box and the bracket through a bearing; an input belt pulley and an output belt pulley are fixedly mounted on the brush rod, the input belt pulley is in driven connection with the driving motor through a driving belt, and the output belt pulley is in driving connection with the screw through the driving belt.

By adoption of the aforementioned solution, the expansion shaft type medical instrument washer according to the present invention is simple in structure, high in cleaning efficiency, convenient to use and can clean the inner surface and the outer surface of a test tube simultaneously.

As shown in FIG. 1 and FIG. 2, an expansion shaft type medical instrument washer provided by an embodiment of the present invention includes a test tube brush formed by a brush rod 1 and bristles 2 planted on the brush rod 1, one end of the brush rod 1 is rotatably mounted on a bracket 3, the brush rod 1 is in driven connection with a driving motor 41, and the brush rod 1 is a columnar rod; a plurality of arc-shaped elastic pieces 19 are symmetrically arranged on the outer surface of the brush rod 1, and the two ends of each arc-shaped elastic piece 19 are fixedly connected to the brush rod 1; the bristles 2 are planted on the outer surfaces of the brush rod 1 and the arc-shaped elastic pieces 19; since the arc-shaped elastic pieces 19 have a certain elasticity and deform after being pressed, when the arc-shaped elastic pieces 19 extend into an inner cavity of a test tube, the bristles can be attached to the inner wall of the test tube well and apply a certain pressure, so that the scrubbing effect is better. As shown in FIG. 2, in addition, sliding rails 5 and 6 are parallel to the brush rod 1, sliding blocks 7 and 8 are mounted in the sliding rails 5 and 6 and can be pushed by a driving mechanism to slide on the sliding rails 5 and 6; the sliding blocks 7 and 8 each are fixedly connected with a nut sleeve 15 and a Y-shaped roll shaft 10, and brush rolls 9 are mounted on the roll shaft 10; a rotatable wheel type round brush can be mounted on the brush roll 9 and a fixed plate type brush can also be mounted; the brush surface towards the brush rod 1 is of an arc-shaped structure matching the outer surface of the test tube, and two brushes forming an included angle can be mounted on the Y-shaped roll shaft 10 simultaneously, to better fit the arc-shaped outer surface of the test tube. A screw 11 is sleeved in the nut sleeve 15, the two ends of the screw 11 are mounted on the sliding rails through bearings, the screw 11 is parallel to the sliding rails 5 and 6, and the screw 11 is driven connection with the driving motor 41.

Further, in order to clean the inner surface and the outer surface of the test tube efficiently and fast, preferably, in this embodiment, a transmission box is parallel to the bracket 3, the driving motor 41 is fixedly mounted in a space between the transmission box 4 and the bracket 3; the brush rod 1 is inserted and mounted on the transmission box 4 and the bracket 3 through a bearing; an input belt pulley 12 and an output belt pulley 13 are fixedly mounted on the brush rod 1, the input belt pulley 12 is in driven connection with the driving motor 41 through a driving belt, and the output belt pulley 13 is located in an inner cavity of the transmission box 4 and is in driving connection with the screw 11 through the driving belt. The sliding rails 5 and 6 are symmetrically arranged above and below the brush rod 1, the brush rolls 9 in the two sliding rails 5 and 6 brush the outer wall of the test tube from an upward direction and a downward direction respectively, the sliding rails 5 and 6 are symmetrically disposed in the up-and-down and left-right directions of the brush rod 1, and the brush rolls in the four sliding rails brush the outer wall of the test tube in the up-and-down and left-right directions of the brush rod 1 respectively. The sliding rails 7 and 8 are fixedly connected with wheel axles 14, and the wheel axles 14 are perpendicular to the sliding rails 5 and 6. Balance wheels 151 are mounted at the two ends of the wheel axles 14 and symmetrically disposed on the two sides of the sliding blocks, and the sliding blocks can keep balance during movement, avoiding tilting towards one side. Therefore, during use, the driving motor 41 drives the brush rod 1 and the screws 11 to rotate, the test tube sleeves the brush rod 1, and the rotating brush rod 1 can clean the inner wall; at the same time, the screws 11 drive the sliding blocks and the brush rolls to move axially, to clean the outer wall of the test tube.
