Description

Infusion device

Technical Field

The invention relates to the field of infusion supports.

Background

The transfusion quantity per capita is reported to be 8-10 bottles in China, and the number of the bottles is on the increasing trend every year.

When a patient transfuses the infusion tube, the infusion tube is long, the patient can place the infusion tube on the ground or at the edge of a chair at will, but the flow of people in a hospital is large, the condition that passing pedestrians trip the infusion tube is often caused, the pedestrians can trip, needles in the operation of the patient can be pulled out due to the fact that the infusion tube is tripped, and serious consequences are caused.

In the prior art, an infusion support is generally arranged higher, so that an infusion tube can be suspended in the air and cannot be placed by a patient randomly due to overlong length.

However, the technology has the following defects that as the infusion support is arranged higher, the height of the infusion support needs to be adjusted when a nurse hangs an infusion bottle each time, but too many patients in a hospital are needed, so that the time is wasted, and the height of the infusion support needs to be adjusted again when the infusion bottle is replaced, which is very inconvenient.

Disclosure of Invention

The invention aims to provide an infusion device, which solves the problems that an infusion tube is too long and can be randomly placed by a patient and the infusion tube can keep the same height.

In order to achieve the purpose, the technical scheme of the invention is as follows:

an infusion device comprises a fixing support, wherein the fixing support comprises a sliding part and a fixing part, threads are arranged on the sliding part, a sliding block is connected onto the sliding part in a sliding manner, a first bevel gear is connected onto the side wall of the sliding block in a rotating manner, a second bevel gear is connected onto the end face of the sliding block in a rotating manner, the first bevel gear is meshed with the second bevel gear, and the second bevel gear is in threaded connection with the sliding part; the first bevel gear is connected with a rotating rod, the free end of the rotating rod is fixedly connected with a winding roller, the rotating rod is also provided with a clockwork spring, one end of the clockwork spring penetrates through the first bevel gear and is fixedly connected to the sliding block, and the other end of the clockwork spring is fixedly connected to the rotating rod; the winding roller is provided with a winding wire, and the free end of the wire is connected with a hook used for connecting an infusion bottle.

The beneficial effect of this scheme does: before the infusion of a patient, a nurse hangs an infusion bottle on the hook, then the winding roller rotates clockwise, the winding roller rotates clockwise and simultaneously drives the clockwork spring and the first bevel gear to rotate clockwise, and the line is wound on the winding roller anticlockwise, so the infusion bottle can descend. The spring is elastically deformed due to the rotation force, and after the rotation is stopped, the gravity of the liquid bottle and the elastic deformation of the spring are balanced, and the spring cannot be deformed at once. The first bevel gear is meshed with the second bevel gear, so that the first bevel gear is driven to vertically rotate by the horizontal rotation of the first bevel gear, the second bevel gear is in threaded connection with the sliding part, and the second bevel gear is in rotational connection with the sliding block, so that the rotating rod is driven to move upwards by the second bevel gear. Therefore, the infusion tube can keep a fixed height, and the infusion tube cannot be randomly placed by a patient due to too long and cannot influence the infusion due to too short. When a patient infuses, the dead weight of the infusion bottle is continuously reduced, the clockwork spring can gradually recover elastic deformation, and then the rotating rod is driven to rotate anticlockwise, and by the principle, the line can drive the infusion bottle to ascend, and the second bevel gear drives the sliding block to descend, so that the height of the infusion tube is still kept consistent. Therefore, when the rotating rod moves upwards, the wire wound on the winding shaft roller is lowered, and when the rotating rod moves upwards, the wire is gradually wound on the winding shaft roller, so that the infusion bottle connected to the wire is always kept at a fixed height. In the whole process, a nurse only needs to adjust the height of the sliding block once before infusion, and the sliding block returns to the initial position after the infusion is finished, so that an infusion bottle can be replaced without adjusting the infusion support again.

Furthermore, the lower end of the fixed part is provided with three supporting legs, and the lower ends of the supporting legs are provided with universal wheels; the beneficial effect of this scheme does: the transfusion stand is convenient for nurses or patients to move.

Further, the spring is a flat steel belt made of 55SiMnVB material; the beneficial effect of this scheme does: the flat steel band of 55SiMnVB material is selected for the clockwork spring, and low price, material durable, sexual valence relative altitude.

Furthermore, an alarm device which is manually pressed down after the transfusion is finished is arranged on the fixed rod; the beneficial effect of this scheme does: when the patient finds that the medicine in the infusion bottle is completely infused, the patient can call a nurse through the alarm device to replace the medicine or pull out the needle.

Furthermore, the tail end of the winding roller is connected with a Z-shaped rotating rod; the beneficial effect of this scheme does: the nurse can make the rotary rod rotatory through rotatory stick, and the operation is more convenient.
