Description

needleless blood collection needle

technical field

The utility model relates to the technical field of medical equipment, in particular to a needleless blood collection needle.

Background technique

An ordinary blood collection needle used to collect blood samples in the medical examination process is composed of a needle head and a needle shaft. The return spring and the initial position of the sheath are located at the head of the needle and the needle shaft. When the operator holds the needle tube and presses the head of the blood collection needle on the patient's limb, the sheath retracts under the elastic force of the skin, making the needle protrude and pierce the body. When the blood collection needle is pulled out, the sheath resets again under the action of the return spring to cover the needle to prevent the needle from being exposed to contamination or accidentally stabbing the human body. When the blood collection needle is pulled out, the cavity surrounded by the needle tube and the skin Gradually increasing, forming an instantaneous negative pressure, which is conducive to the collection of blood samples, but most of the common blood collection needles are easy to stab patients or medical staff during use, increasing the incidence of needlestick injuries and the infection rate of infectious diseases. And repeated punctures are easy to injure the patient. In addition, when the blood collection volume is too large, ordinary blood collection needles cannot meet the work requirements. In view of the above deficiencies, improvements are now made.

Utility model content

The purpose of this utility model is to provide a needle-free blood collection needle to solve the problems raised in the above-mentioned background technology. It has become a new type of blood collection device, which reduces the incidence of stab wounds of patients and medical staff and the infection rate of infectious diseases during use. When using a needleless blood collection needle to meet the work requirements, the end of the needleless connector close to the PICC tube is fixed with an alcohol wiping device through a rivet. When alcohol is needed to wipe the patient's blood collection site, the alcohol wiping device on the top of the trocar can be directly rotated Control the switch, the sealing plug is far away from the groove, the alcohol in the alcohol box flows into the inverted triangle through the through hole opened on the groove, and makes the alcohol quickly and evenly cover the sponge head, remove the protective cover on the sponge head, and the patient can be treated The blood collection site needs to be wiped with alcohol, and then the blood is collected, which avoids the cumbersome carrying process in the past. A protective cover is installed on the outside of the sponge head on the alcohol wiping device to prevent bacterial dust from falling in. There is an alcohol perfusion hole on the alcohol box. When the alcohol is not enough, alcohol can be added through the alcohol filling hole. The alcohol filling hole is hinged with an alcohol filling hole cover, which can prevent bacteria and dust from falling in. The utility model has reasonable design, simple structure, convenient operation and strong practicability.

In order to achieve the above object, the utility model provides the following technical solutions: a needleless blood collection needle, including a PICC tube, a cork puncture needle, a needleless connector, a blood collection test tube and an alcohol wiping device, one end of the PICC tube is connected with a cork puncture needle Needle, and one end of the cork puncture needle is inserted into the blood collection test tube, the other end of the PICC tube is connected with a needleless joint, and the end of the needleless joint close to the PICC tube is fixed with an alcohol wiping device through a rivet, and alcohol wiping device is installed inside the alcohol wiping device. box, the bottom of the alcohol box is provided with an inverted triangle mouth, the upper end of the inverted triangle mouth is provided with a groove, and a sealing plug matching the groove is installed above the inverted triangle mouth, and the sealing plug is connected with the alcohol through the connecting rod. The control switch on one side of the box is connected, and the end of the alcohol wiping device near the alcohol box is equipped with a sponge head, and the sponge head is connected to one end of the inverted triangle mouth.

Preferably, the needle-free connector is connected to a bottle stopper puncture needle through a PICC tube or a trocar (not shown in the drawings).

Preferably, the groove is provided with a through hole.

Preferably, a protective cover is installed on the outside of the sponge head.

Preferably, the side of the alcohol box away from the control switch is provided with an alcohol filling hole, and an alcohol filling hole cover is hinged on the alcohol filling hole.

Compared with the prior art, the beneficial effect of the utility model is that the common blood collection needle is replaced by a needleless joint, and then connected with a trocar or PICC tube to form a new type of blood collection device, which reduces the need for patients and medical services during use. The incidence of personnel stab wounds and the infection rate of infectious diseases can also reduce repeated punctures to achieve good results in protecting patients' blood vessels. When the blood collection volume is too large, use needleless blood collection needles to meet work needs, and the needleless connector is close to PICC One end of the tube is fixed with an alcohol wiping device by a rivet. When it is necessary to use alcohol to wipe the patient's blood collection site, you can directly rotate the alcohol wiping device on the top of the trocar, turn on the control switch, the sealing plug is far away from the groove, and the alcohol in the alcohol box passes through. The through hole opened on the groove flows into the inverted triangular mouth and the alcohol is quickly and evenly covered with the sponge head. After removing the protective cover on the sponge head, alcohol can be used to wipe the patient's blood collection site, and then the blood collection can be performed, avoiding the cumbersome procedures in the past. During the carrying process, a protective cover is installed on the outside of the sponge head on the alcohol wiping device to prevent bacteria and dust from falling in. There is an alcohol filling hole on the alcohol box. When the alcohol in the alcohol box is not enough, alcohol can be filled through the alcohol filling hole. The hole is hinged with an alcohol pouring hole cover, which can prevent bacterial dust from falling in. The utility model has reasonable design, simple structure, convenient operation and strong practicability.
