Abstract
The utility model relates to a retention needle, which comprises a needle head assembly and an infusion joint assembly, wherein the needle head assembly comprises a cannula seat and a puncture needle; the cannula seat is divided into an injection cavity and a needle base cavity by an isolation plug; a handhold part is arranged on a needle handle of the puncture needle; a steel needle protective sleeve is sleeved on the outer wall of the needle base cavity and has a draw-and-pull structure which consists of 3 to 4 sections of sleeves; a needle handle check ring is arranged at the rear end of the first section of sleeve; a clamping buckle is arranged between the last section of sleeve and the outer wall of the needle base cavity; a draw-and-pull locking mechanism is arranged between the adjacent sleeves; and a gap corresponding to the handhold part of the needle handle is formed at the rear end of each section of sleeve. According to the retention needle, the puncture needle is withdrawn after puncture is finished, each section of the sleeve in the steel needle protective sleeve is unfolded, and after the puncture needle is arranged in the steel needle protective sleeve completely, the steel needle protective sleeve is pulled, so that the steel needle protective sleeve is separated from the cannula seat; and the unfolded steel needle protective sleeve wraps the puncture needle completely, so that medical care personnel is prevented from being punctured by a needle tip again after the puncture is finished to fulfill the aims of safety protection and prevention of cross infection.
Description
Technical field
This utility model relates to a kind of transfusion medical apparatus and instruments, particularly a kind of remaining needle.
Background technology
The Along with people's growth in the living standard, the remaining needle less to blood vessel injury has been widely used in clinical.But the puncture needle in the transfusion operation process has broken away from remaining needle after puncture finishes to release, its needle point is prone to stab medical personnel or other personnel, medical personnel is injured and cross infection, arbitrarily puts simultaneously, causes environmental pollution easily.
Summary of the invention
This utility model technical problem to be solved is the deficiency to prior art, provides a kind of rational in infrastructure, easy to use, the remaining needle that can whole puncture needle be protected.
This utility model technical problem to be solved is to realize through following technical scheme, and this utility model is a kind of remaining needle, comprises needle assembly, fluid injection adapter assembly; Connect through conduit between needle assembly and the fluid injection adapter assembly, described needle assembly comprises casing seat and puncture needle, and described casing seat front end is provided with the indwelling flexible pipe; Batching pig is housed in the casing seat; Casing seat is divided into fluid injection chamber and needle stand chamber through batching pig, and puncture needle comprises syringe needle and needle handle, and needle handle is provided with the Handheld Division; Be characterized in: be set with the draw point protective jacket on the needle stand cavity outer wall; Described draw point protective jacket is the drawing and pulling type structure that 3-4 joint sleeve is formed, and the telescopic rear end of first segment is provided with the needle handle back-up ring, is provided with buckle between final section sleeve and the needle stand cavity outer wall; Be provided with the pull retaining mechanism between the adjacent sleeve, the telescopic rear end of every joint is provided with the breach of position, corresponding needle handle Handheld Division.
This utility model technical problem to be solved can also further realize through following technical scheme; Said pull retaining mechanism comprises the draw-in groove that is arranged on wherein a joint sleeve ends, saves telescopic end at corresponding another and is provided with the elasticity card that cooperates with draw-in groove.
This utility model saves the drawing and pulling type structure draw point protective jacket that sleeve is formed through on the needle stand cavity outer wall of casing seat, being set with by 3-4, during use, when puncture finishes to withdraw from puncture needle; The Handheld Division of hand-held puncture needle; Make a section expansion of draw point protective jacket, after puncture needle placed in the draw point protective jacket fully, pulling made the draw point protective jacket break away from casing seat again; Draw point protective jacket after the expansion with the syringe needle whole protection of puncture needle in cover; After having avoided puncture to finish, needle point is stabbed medical personnel once more, reaches security protection and prevents the purpose of cross infection.
Compared with prior art, it is reasonable in design, and is simple in structure, makes easy to usely, need not handle especially puncture needle in the infusion process, has stopped puncture needle and has been prone to the phenomenon that thorn is hurted sb.'s feelings, and has made things convenient for clinical use.
