detailed description

Below in conjunction with accompanying drawing, the utility model is further described. As shown in Figure 1 and Figure 2, a clip-on drainage bag connector includes a drainage bag connection part and a drainage tube connection part, and the drainage bag connection part is composed of a drainage bag connection sleeve 9, a connecting intubation tube 1 and a snap-in connection. Sleeve 2 is composed of connecting cannula 1 which is an inverted tapered cannula with a large upper part and a smaller lower part. An annular clamping table 9-1 is arranged in the drainage bag connecting sleeve 9 . One end of the drainage bag connecting sleeve 9 is sleeved at the connecting port of the drainage bag connecting pipe 10, and the mouth of the drainage bag connecting pipe 10 is sealed and connected with the annular card table 9-1, and the drainage bag connecting sleeve 9 is connected with the drainage bag. A sealing rubber ring 12 is provided between the tubes 10 to increase its sealing effect and avoid liquid leakage or air leakage during the drainage process; The clamping sleeve 2 is fixedly sleeved outside the drainage bag connecting sleeve 9, and an annular clamping groove 3 is formed between its inner wall and the outer wall of the drainage bag connecting sleeve 9; The connecting sleeve 4, the connecting seat 5 and the snap-in tube 6 are composed, and the lower part of the connecting sleeve 4 of the drainage tube is fixedly sleeved at the connection port of the drainage tube 7, and there is a set between the connecting sleeve 4 and the drainage tube 7. The sealing rubber ring 12 makes it airtightly connected. The upper part of the drainage tube connection sleeve 4 is fixedly connected with the connection seat 5, and the connection seat 5 is communicated with the drainage tube 7, and the socket 8 having the same shape and size as the connection intubation tube 1 of the drainage bag connection part is provided in the connection seat 5 , the clamping tube 6 is arranged on the upper end of the connecting seat 5; as shown in Figure 3 and Figure 4, when the drainage bag connection part and the drainage tube connection part are connected, the connecting intubation tube 1 is completely embedded in the socket 8, and passes through the socket 8 communicates with the drainage tube 7, and the clamping tube 6 is embedded in the annular clamping groove 3. The clamping tube 6 is the same size as the annular clamping groove 3, and can be completely embedded in the annular clamping groove 3.

In order to prevent the phenomenon that the connection part of the drainage bag and the connection part of the drainage tube are snapped together, as shown in Figure 1 and Figure 2, there can be a snap-fit member 11 that matches each other on the snap-in tube 6 and the snap-in sleeve 2, so that The clamping member 11 is composed of an elastic bayonet pin 11-1 arranged on the bayonet tube 6 and a positioning hole 11-2 arranged on the bayonet sleeve 6, and the elastic bayonet pin 11-1 and the positioning hole 11 -2 is set at the same height after the clamping tube 6 and the clamping sleeve 2 are clamped. There is also a bayonet groove on the snap-in tube 6. When the drainage bag connection part is connected to the drainage tube connection part, the elastic bayonet pin 11-1 and the positioning bayonet hole 11-2 are misaligned. The bayonet pin 11-1 is pressed into its bayonet groove, which will not affect the connection of the two parts. When the bayonet pipe 6 is completely embedded in the annular bayonet groove 3, the bayonet pipe 6 or the bayonet sleeve 2 is rotated, and when the elastic bayonet pin 11-1 Rotate to the position of the positioning card hole 11-2, it will automatically pop up and be inserted into the positioning card hole 11-2, and the clamping tube 6 and the clamping sleeve 2 are positioned to prevent the two from falling off at will.

Both parts of the utility model are made of medical plastic, one part is directly fixed on the drainage bag, and the other part is fixed at the joint of the drainage tube. When connecting the drainage bag and the drainage tube, only the connecting part of the drainage bag needs to be Tube 1 is inserted into the jack 8 of the drainage tube connection part, and at the same time, the clamping tube 6 of the drainage tube connection part is inserted into the annular slot 3 of the drainage bag connection part. The holes 11-2 are misaligned with each other. After the insertion is completed, turn the snap-in tube 6 or the snap-in sleeve 2 so that the elastic bayonet pin 11-1 is aligned with the positioning bayonet 11-2, and snapped into the positioning bayonet 11-2. its positioning. When the drainage bag needs to be replaced, only the elastic bayonet pin 11-1 is pressed by hand, and the connection part of the drainage bag is pulled out, so that the connecting intubation tube 1 can be pulled out from the jack 8, which is simple and convenient.
