Description

Umbilical vein puncture needle with hooking function

Technical Field

The utility model relates to the technical field of medical appliances, in particular to an umbilical vein puncture needle with a hooking function.

Background

With the aggravation of the aging society in China, the number and quality of new-born population are improved, the current construction of the society population is important, the existing medical technology can know the corresponding health condition of the fetus to a great extent when the fetus is inoculated in the mother, and accurate and reasonable treatment and maintenance are provided, and the operations are largely indispensible from the umbilical cord puncture technology.

Currently, umbilical cord puncture is usually performed by puncturing a puncture needle through the skin of the abdominal wall into the umbilical vein, and performing genetic examination or intravenous infusion treatment on a baby fetus. The proper position is selected while the ultrasonic monitoring is performed, and the umbilical vein is penetrated by the skin of the abdominal wall of pregnant mother through the puncture needle.

However, such conventional puncture needles, although being easy to pierce the umbilical vein when performing the puncture, are very easy to cause the puncture needle to slip out of the umbilical vein to cause operation failure due to tremor or self-flow of blood in the umbilical vein when performing the subsequent intravenous injection or extraction, and the umbilical vein puncture needle has no other auxiliary fixing means.

Therefore, the utility model aims to provide an umbilical vein puncture needle with a hooking function, so as to solve the problem that in the prior art, the umbilical vein puncture needle cannot be used for auxiliary fixation of umbilical vein after puncture, and thus the puncture needle is easy to slide out of the umbilical vein to cause operation failure.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

the umbilical vein puncture needle with the hooking function comprises a puncture needle body, wherein a hooked needle is arranged in the puncture needle body.

Further, the pjncture needle body includes pjncture needle and pjncture needle joint, the sliding tray has been seted up to the pjncture needle joint, the outside slip of sliding tray is provided with the crochet hook regulator, the fixed crochet hook fixed block that is provided with in crochet hook top, crochet hook fixed block passes through spliced pole fixed connection with the crochet hook regulator. The hooked needle fixing block is driven to stretch and retract through the sliding of the hooked needle adjuster, so that the hooked needle is exposed and retracted, and the hooked needle hooking operation can be conveniently controlled.

Further, the crochet is two crochet with opposite needle curling directions. The hooked needle with opposite curling directions is beneficial to hooking umbilical veins from different directions after the hooked needle enters the umbilical veins, so that the umbilical veins are ensured to be hooked more firmly.

Further, the length value of the crochet needle is greater than the length value of the puncture needle. The length value of the crochet needle is set to be larger than that of the puncture needle, so that the crochet needle can be hooked in a sufficient length after being pushed out of the puncture needle, and the hooking effect can be guaranteed.

Further, the connecting post passes through the sliding groove, and the connecting post is matched with the sliding groove in size. Through with spliced pole and sliding tray size matched with, be favorable to realizing that crochet hook regulator slides and can more smoothly drive the crochet hook flexible, promote the simple operation nature.

Further, the outer surface of the crochet hook adjuster is provided with a rough surface. The outer surface of the crochet hook adjuster is provided with the rough surface, so that friction is increased to prevent slipping when the crochet hook adjuster is pushed.

Further, the crochet is a silver needle, and the crochet is manufactured by crimping an end of the silver needle. The silver needle is used as the crochet needle, so that self-cleaning disinfection and sterilization of the silver needle can be realized, the crochet needle is prepared by curling the end part of the silver needle, and the formation of a return hook by the end part curling of the crochet needle for recovering the original curled state when the crochet needle is pushed out can be realized, so that the hooking function is realized.

Further, the two bearded needles are symmetrically arranged, the distance value between the two bearded needles is smaller than the inner diameter size of the puncture needle, and the extension size of the curled portion of the two bearded needles is larger than the outer diameter size of the puncture needle. The distance value between the symmetrically arranged crochets is smaller than the inner diameter of the puncture needle, so that the crochets can be restrained and straightened by the puncture needle when the crochets are received in the puncture needle, and the curled part extending size of the two crochets is set to be larger than the outer diameter of the puncture needle, so that the curled size generated for recovering the original curled state when the crochets are pushed out of the puncture needle is larger than the puncture needle, and the part extending out of the crochets can be firmly hooked to fix the umbilical vein to avoid the puncture needle from sliding out.

The utility model has the following beneficial effects:

the umbilical vein puncture needle with the hook needle is arranged, and a structure capable of hooking and fixing the umbilical vein is provided, so that the umbilical vein puncture needle can be used for assisting in fixing the umbilical vein hooked by the hook needle after puncture, and the puncture needle is ensured to be in the umbilical vein in the whole process when the puncture needle is used for pumping and conveying the umbilical vein, and operation failure caused by slipping out of the umbilical vein is avoided.
