Abstract
The utility model discloses a prevent stabbing pjncture needle, including needle tubing (1) that has pointed syringe needle (11), gripping member (2), spring (3), push rod (4), dog (5), open near syringe needle (11) position needle tubing (1) has water conservancy diversion hole (12), needle tubing (1) and gripping member (2) fixed connection, be provided with liquid collecting cavity (21) in gripping member (2), spring (3) are arranged in liquid collecting cavity (21), push rod (4) arrange in needle tubing (1) and both ends respectively with spring (3), dog (5) fixed connection, push rod (4) can remove along the axis in needle tubing (1) under the effort of dog (5), dog (5) one end when natural state is located the position that surpasss needle point (11), dog (5) are whole needle tubing (1) the cavity that is located when the puncture. The utility model discloses avoided syringe needle in puncture operation (11) to hurt the important internal organs in the body cavity.
Description
Technical field
This utility model relates to a kind of medical puncturing apparatus, particularly relates to a kind of Anti-stabbing puncture needle.
Background technology
Paracentesis are one of clinical conventional diagnostic methods, and such as pleurocentesis its object is to the pressure clarifying a diagnosis and alleviate internal organs.Existing puncture needle is difficult to accurately hold penetration depth, the repeatedly pumpback of normal needs, when breast intracavity gas or liquid are taken out fewer and fewer, visceral pleura more and more presses close to parietal pleura, as thought, as far as possible extracting gases or liquid need to convert needle tip position patient often, so very easily damage visceral pleura, internal organs.If the hydrops amount in chest is few, when point of puncture position is on the lower side or site of puncture closes on important organ or blood vessel, so more easily damage.
Utility model content
Technical problem to be solved in the utility model is to provide the Anti-stabbing puncture needle that a kind of structure is simple, can prevent the needle sting inside of human body important organ of puncture needle.
This utility model solves the technical scheme that its technical problem adopts: Anti-stabbing puncture needle, comprise the needle tubing with pointed syringe needle, characterized by further comprising: gripping member, spring, push rod, block, described needle tubing has pod apertures near needle position, described needle tubing is fixedly connected with gripping member, liquid collecting cavity is provided with in described gripping member, described spring is placed in liquid collecting cavity, described push rod be placed in needle tubing and two ends respectively with spring, block is fixedly connected with, described push rod can move along axis under the active force of block in needle tubing, described block one end when naturalness is positioned at the position exceeding needle point, described block entirety when puncturing is positioned at needle tubing cavity.
Wherein, described gripping member is provided with tap.
Wherein, described block front end is hemispherical.
The beneficial effects of the utility model are: provide a kind of structure simple Anti-stabbing puncture needle, comprise needle tubing, gripping member, spring, push rod, block, its block one end when naturalness is positioned at the position exceeding needle point, avoid after syringe needle enters body cavity, owing to being difficult to hold paracentesis depth, repeatedly adjusting the position of puncture and cause exposed sharps injury to occur to the situation of other important organ of inside of human body.
Accompanying drawing explanation
Fig. 1 is this utility model wherein a kind of embodiment generalized section in the raw;
Fig. 2 be this utility model wherein a kind of embodiment be in the generalized section of puncture state.
Be labeled as in figure: needle tubing 1, gripping member 2, spring 3, push rod 4, block 5, syringe needle 11, pod apertures 12, liquid collecting cavity 21, tap 22.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further illustrated.
This utility model Anti-stabbing puncture needle, comprise the needle tubing 1 with pointed syringe needle 11, also comprise: gripping member 2, spring 3, push rod 4, block 5, described needle tubing 1 has pod apertures 12 near syringe needle 11 position, described needle tubing 1 is fixedly connected with gripping member 2, liquid collecting cavity 21 is provided with in described gripping member 2, described spring 3 is placed in liquid collecting cavity 21, described push rod 4 be placed in needle tubing 1 and two ends respectively with spring 3, block 5 is fixedly connected with, described push rod 4 can move along axis under the active force of block 5 in needle tubing 1, described block 5 one end when naturalness is positioned at the position exceeding needle point 11, described block 5 entirety when puncturing is positioned at needle tubing 1 cavity.
Above-mentioned naturalness is the state that Anti-stabbing puncture needle is placed in outside human body completely.Syringe needle 11 completes and penetrates the tissue such as human body skin, muscle and enter after body cavity also in naturalness.
As shown in Figure 2, in the process of puncture, due to the stop of the tissue such as skin, muscle, block 5 is subject to a larger power, and block 5 drives push rod 4 Compress Spring 3 backward, causes spring 3 to be in compressive state (namely puncture state); As shown in Figure 1, after needle point 11 enters body cavity, resistance disappears, and when block 5 gets back to naturalness under spring 3 active force, one end is positioned at the position exceeding needle point 11, thus avoids needle point 11 be directly exposed to outer and cause damage human body important organ.Described needle tubing 1 has pod apertures 12 near syringe needle 11 position, and when block 5 is in naturalness, pod apertures 12 is in exposed state, and cerebrospinal fluid, tissue fluid, gas etc. can be drained body cavity by pod apertures 12.
Above-mentioned Anti-stabbing puncture needle, described gripping member 2 is provided with tap 22.Tap 22 can external drainage tube so that the endoceliac liquid of drain or gas.Wherein, described needle tubing 1, gripping member 2, tap 22 is through to be integrated.
Above-mentioned Anti-stabbing puncture needle, described block 5 front end is hemispherical, plays the effect protecting internal viscera better.Wherein, described block 5 front end is the one end that can exceed needle point 11.
Claims (3)
1. Anti-stabbing puncture needle, comprise the needle tubing (1) with pointed syringe needle (11), characterized by further comprising: gripping member (2), spring (3), push rod (4), block (5), described needle tubing (1) has pod apertures (12) near syringe needle (11) position, described needle tubing (1) is fixedly connected with gripping member (2), liquid collecting cavity (21) is provided with in described gripping member (2), described spring (3) is placed in liquid collecting cavity (21), described push rod (4) be placed in needle tubing (1) and two ends respectively with spring (3), block (5) is fixedly connected with, described push rod (4) can move along axis under the active force of block (5) in needle tubing (1), described block (5) one end when naturalness is positioned at the position exceeding needle point (11), described block (5) entirety when puncturing is positioned at needle tubing (1) cavity.
