Push handle clamping device for syringes of syringe pumps

Abstract

A push handle clamping device for a syringe of a syringe pump, comprising a shell, a lever, a connecting rod, a limiting part, an elastic part, a claw and a button. The middle part of the lever is rotatably connected with the housing; the connecting rod is slidably installed in the housing, and one end is movably connected with one end of the lever; the limiter is fixed on the connecting rod; the elastic member is sleeved on the connecting rod, and the The two ends are opposed to the inner wall of the housing and the stopper respectively; the jaws are set on the housing and fixedly connected to the end of the connecting rod away from the lever, and the jaws cooperate with the outer surface of the housing to clamp the push handle of the syringe The button is slidably mounted on the housing, the button is in contact with the end of the lever away from the connecting rod, the button can slide toward the inside of the housing to push the lever to rotate, and the connecting rod slides toward the direction extending out of the housing. The above-mentioned push handle clamping device for the syringe of the syringe pump is easy to operate and comparatively easy to operate.

Description

technical field [0001] The invention relates to a push handle fastening device for a syringe of a syringe pump. Background technique [0002] At present, domestic hospitals are gradually promoting the use of syringe pumps to realize automatic injection in clinical intravenous injection because of the accuracy and ease of regulation of syringe pump injection. When using a syringe pump, there are mainly two types of structures on the market for installing the push handle at the rear end of the syringe. One is a fixed structure, and the push handle is caught by an elastic barb. When installing the syringe, it needs to be pulled apart first. Then press the clutch on the injection head of the injection pump with one hand and drag the push rod to the push handle at the rear end of the syringe. With the other hand, snap the push handle of the syringe into the fixed structure on the injection head. After adjustment Put it into the card slot and close the handle. However, this type ...

When using a syringe pump, there are mainly two types of structures on the market for installing the push handle at the rear end of the syringe. One is a fixed structure, and the push handle is caught by an elastic barb. When installing the syringe, it needs to be pulled apart first. Then press the clutch on the injection head of the injection pump with one hand and drag the push rod to the push handle at the rear end of the syringe. With the other hand, snap the push handle of the syringe into the fixed structure on the injection head. After adjustment Put it into the card slot and close the handle. However, this type requires medical personnel to use both hands to operate at the same time, and the operation is cumbersome and very inconvenient. The position near the push handle prevents the syringe push handle from deviating from the push rod. This type can be operated with one hand, but this type of locking method actually frames the push rod at the front end of the syringe push handle and cannot directly act on the syringe push handle. , very unsafe
