Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention are clearly and completely described below, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The invention is further described below with reference to the accompanying drawings:
as shown in figure 1: the utility model provides a blood taking needle that needle used is kept somewhere in cooperation, this blood taking needle are disposable blood taking needle, include: the connector 1 is used for connecting with an interface of the remaining needle; the liquid sealing head 2 is used for injecting medicine and tube sealing liquid, the liquid sealing head 2 is detachably connected with a protective cap 3, and a connecting column of the protective cap 3 extends into a pipeline of the liquid sealing head 2 and is hermetically connected with the liquid sealing head 2; the blood taking needle 4 is used for being connected with a vacuum blood taking tube, a rubber protective sleeve 5 is fixedly sleeved outside the blood taking needle 4, and a plastic protective sleeve 9 is detachably sleeved outside the rubber protective sleeve 5; connecting pipe 6, the one end and the connector 1 of connecting pipe 6 switch on, and the other end and the blood taking needle 4 of connecting pipe 6 are connected, and connecting pipe 6 intercommunication has branch pipe 7, and the one end and the connecting pipe 6 of branch pipe 7 switch on, and the other end and the first 2 of liquid of sealing of branch pipe 7 are connected, and 6 covers of connecting pipe between branch pipe 7 and the blood taking needle are equipped with the stagnant water and press from both sides 8. Need just for just establish and keep somewhere needle venous passage or when having the patient of keeping somewhere the needle and gather blood, can directly be connected to connector 1 and keep somewhere the needle interface, be connected to the vacuum test tube with blood taking needle 4, it is sealed to seal liquid head 2, the stagnant water clamp is opened, utilize the negative pressure of vacuum test tube to gather blood to the vacuum test tube, gather the back, close stagnant water clamp 8, remove helmet 3, it advances the liquid medicine or seals the pipe fluid to locate from sealing liquid head 2, a treatment for the vein is injected the medicine or is prevented to keep somewhere the interior blood coagulation of needle and is produced the blood clot, cause stifled pipe.
