Problems solved by technology

[0003] But although this catheter setter 9 can be used as a medium for injecting medicine or drawing blood, it is unavoidable to have the situation that the needle body 94 is improperly exposed in the operation process, so as long as there is a little carelessness, there will be thorns. The danger of injuring medical personnel, causing pain or even the risk of fatal infectious disease infection, it is important that the catheter setter 9 does not have the function of drawing and measuring b

Abstract

The invention discloses an intravenous catheter locator, which mainly comprises a syringe, a needle set and a push rod, wherein the needle set is provided with a positioning piece which is positioned in the syringe, a needle seat which is limited between the positioning piece and the syringe, a needle body which passes through the syringe, a catheter seat which is sleeved on the syringe and a flexible catheter which is jointed with the catheter seat and allows the needle body to pass through. The needle seat is provided with a cavity wall which defines a cavity and is used for observing the cavity. The push rod is provided with at least one vent port which is communicated with the outside air pressure and a connecting piece which is sleeved with the needle seat. When the vent port is closed to carry out a testability phlebotomizing step, the circulating situation of back-flow blood in the cavity is observed through the cavity wall. When the vent port is opened, the back-flow blood can be flowed into the connecting piece, and the displacement of the push rod can be used for starting the connecting piece so as to link the needle seat and the needle body to hide in the push rod.

Description

technical field [0001] The invention relates to a catheter setter, in particular to an intravenous catheter setter capable of sampling blood and hiding a needle body. Background technique [0002] In general clinical medicine, when administering intravascular infusion drip injection to patients, the intravascular infusion catheter is often used to continuously infuse drip infusion, refer to figure 1 Taking the general catheter setter 9 as an example, it mainly includes a needle hub 91, a catheter hub 92 socketed with the needle hub 91, a hollow and flexible catheter 93 connected with the catheter hub 92, and The needle hub 91 engages with and passes through a needle body 94 of the catheter 93 . When the medical personnel hold the needle holder 91 and puncture the blood vessel of the animal body with the needle body 94, the catheter 93 can be guided into the blood vessel, and the catheter 93 can be left in the blood vessel after the needle body 94 is withdrawn. Inside, and ...
