Detailed Description

Referring to fig. 1-4, the present invention provides the following technical solutions: the utility model provides a novel blood taking needle, is including the needle body 1 that is used for the blood sampling, and the connecting pipe 3 that is used for connecting outside injection connector detection pricking position is installed through mount pad 2 to the upper end of needle body 1, and the inside fixedly connected with of connecting pipe 3 carries out spacing sealing rubber stopper 4 to outside syringe tip, and the male deformation mouth 41 of outside syringe of being convenient for is seted up to sealing rubber stopper 4's inside.

In this embodiment: when a medical worker pricks a needle to take blood for an infant, the medical worker can prick a blood vessel to take blood through the blood sampling needle at the end part of the needle body 1, wherein the needle body 1 is a main blood taking tool for blood sampling work, at the moment, a passage is formed between the front end part of the needle body 1 and the connecting pipe 3 under the connection of the mounting seat 2, after the medical worker finishes the pricking for the infant patient, the connecting pipe 3 provides a carrier for the connection with an external injector, when the external injector finishes the mounting through the connecting pipe 3, a blood channel is formed between the external injector and the front end part of the needle body 1, at the moment, the medical worker can draw blood outwards through the external injector, judge whether the needle head at the end part of the needle body 1 is inserted into the blood vessel or not according to the blood returning condition at the front end part of the needle body 1, when the front end part of the needle body 1 bleeds under the blood drawing of the external injector, the judgment that the needle head of the needle body 1 is inserted into the blood vessel or not is performed, otherwise, therefore, medical staff can judge whether the needle head at the end part of the needle body 1 is inserted into a blood vessel and open external negative pressure according to the insertion condition of the needle head to perform subsequent blood drawing work, at the moment, under the mutual matching of the needle body 1, the mounting seat 2 and the connecting pipe 3, a complete blood drawing needle capable of detecting the insertion position of the needle head after the needle insertion is completed is formed, the insertion position of the needle head can be detected by communicating an external injector through the connecting pipe 3, the medical staff can conveniently judge the insertion position of the needle head in the blood drawing tube according to the blood drawing condition of the injector, thereby avoiding the failure of blood drawing through negative pressure due to the deviation of the needle head insertion caused by the thinner blood vessel of the baby when the baby takes blood, further improving the blood drawing success rate when the negative pressure is used for blood drawing, reducing the waste of the negative pressure blood drawing tube in the blood drawing process, and when the external injector is connected, the tip of outside syringe runs through to the inner chamber of mount pad 2 through deformation mouth 41 to accomplish the work of drawing blood and looking over the syringe needle condition of inserting, sealed rubber buffer 4 plays sealed effect for the return circuit that forms between connecting pipe 3 and the needle body 1 front end this moment, wherein when the outside syringe is connected to the deformation mouth 41 of seting up in sealed rubber buffer 4 inside, at first insert the syringe needle through connecting pipe 3 in the deformation mouth 41, wherein the deformation mouth 41 is closed under the elastic effect of rubber self under the state that no foreign object got into, after the tip of outside syringe inserted deformation mouth 41, the inside of deformation mouth 41 received the extrusion and outwards compressed, the tip outer wall of outside syringe forms the through-hole, make the syringe can pass deformation mouth 41 and get into the inside of mount pad 2.

The mounting seat 2 is communicated with the needle body 1 through a connecting hose 21; wherein mount pad 2 is split type can conveniently produce through the equipment mode at the in-process that this kind of blood taking needle produced with needle body 1, only need with the both ends of needle body 1 respectively with mount pad 2 be connected through coupling hose 21 can, improved the efficiency in process of production.

A sealing plate 22 for sealing the internal liquid feeding through hole is elastically hinged in the mounting seat 2; when the syringe is inserted into the mounting seat 2 through the deformation port 41, one side of the sealing plate 22 rotates to one side under the pressing force of the syringe, and the sealing plate can seal the channel between the mounting seat 2 and the lower end of the needle body 1 while rotating, so that a sealed loop is formed between the connecting tube 3 and the upper end of the needle body 1.

The top of the connecting pipe 3 is provided with a guide port 31 which is convenient for workers to confirm the position of the deformation port 41 for connecting an external injector; wherein the position of guiding opening 31 corresponds with the position of deformation mouth 41, because sealing rubber buffer 4 is located the inside of connecting pipe 3, medical personnel are not convenient for judge the position of deformation mouth 41 from the outside, and the position of below deformation mouth 41 can be judged through the position of guiding opening 31 this moment, the staff's of being convenient for operation.

The outer side of the connecting pipe 3 is connected with a dustproof plug 32 for sealing the guide opening 31 through an elastic connecting rope; wherein the dustproof plug 32 can prevent the dust from entering the interior of the connecting pipe 3 and polluting the sealing rubber plug 4, which affects the safety in the using process.

The length of the sealing plate 22 is less than that of the short side of the mounting seat 2; at this time, it is possible to avoid interference of the inner wall of the mounting seat 2 with the rotation of the sealing plate 22 when the sealing plate 22 rotates in the mounting seat 2.

The deformation port 41 is arranged at one end of the sealing rubber plug 4 close to the hinge joint of the sealing plate 22; at this time, when the syringe enters the mounting seat 2 through the deformation port 41 to press the sealing plate 22, the pressing is performed from one side close to the hinged end of the sealing plate 22, so that the sealing plate 22 after the pressing is completed can be tightly attached to the inner wall of the mounting seat 2 close to the through hole at the lower end of the needle body 1, and the sealing effect of the through hole at one side is improved.

The working principle and the using process of the utility model are as follows: when medical personnel are pricking the needle and get blood for the baby, the blood vessel is pricked to the blood sampling needle of 1 tip of accessible needle body and is got blood, is connected outside syringe and connecting pipe 3 afterwards to outwards draw blood through outside syringe, when the front end of needle body 1 when bleeding under the blood of drawing of outside syringe, then can judge that the syringe needle of needle body 1 has inserted in the blood vessel, otherwise then opposite, medical personnel can open outside negative pressure according to the condition of inserting of syringe needle afterwards and carry out subsequent work of drawing blood.
