Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention will be further described:

[0024] Such as figure 1 As shown, the present invention proposes an anti-injury puncture catheter and a sealing device, the device includes a soft sleeve 1, a puncture needle 2 and an aspirator 3, a Y-shaped mouth is arranged at the root of the soft sleeve, and the Y-shaped mouth One end is connected to the aspirator 3, and the other end is provided with an overflow prevention device 4; when the puncture needle 2 is used, it is inserted into the soft sleeve 1 from the overflow prevention device 4. The connected water detection side hole 5, when the puncture needle 2 is inserted into the soft sleeve 1, the water detection side hole 5 communicates with the Y-shaped mouth. The inner chamber of the puncture needle 2 communicates with the needle hole at the needle tip 11 of the puncture needle 2 .

[0025] The front end of the puncture needle 2 is provided with a diameter-red...

Abstract

Provided are an injury-preventing puncture catheter and a closing device. The closing device comprises a soft sleeve, a puncture needle and an aspirator, wherein a Y-shaped opening is formed in the root portion of the soft sleeve, one end of the Y-shaped opening is connected with the aspirator, an overflow preventing device is arranged at the other end of the Y-shaped opening. When the puncture needle is used, the puncture needle is inserted into the soft sleeve from the overflow preventing device, a water detecting side hole communicated with the inner cavity of the puncture needle is formed in the side wall of the puncture needle, and the water detecting side hole is communicated with the Y-shaped opening when the puncture needle is inserted into the soft sleeve. The inner cavity of the puncture needle is communicated with a needle hole at the point of the puncture needle. Puncturing and liquid suction and discharge are both completed in a closed system. After the puncture needle is pulled out during final liquid discharge, the liquid suction and discharge process is completed by the soft sleeve 1 in the body cavity, so that a patient does not produce the nervous emotion due to the fact that the steel needle is in the body. One doctor can complete the liquid suction and discharge and does not have to worry an accident and other situations of the steel needle in the body, and the labor intensity is reduced.
