Description
Technical field
This utility model relates to a kind of medical care apparatus, specifically a kind of intrabone infusion device.
Background technology
The approach of the liquid resuscitation adopted when promptly rescuing clinically or input medicine mainly contains three kinds of modes in vein, tremulous pulse and bone, wherein intraosseous infusion is mainly used in the rescue that the state of emergency is heavy patient, as patients such as respiratoring palpitating suddenly stopping, severe trauma hemorrhagic shock, severe dehydration, infant serious dehydration, this kind of patient cannot set up blood vessel first aid passage quickly and efficiently because a large amount of liquid of losing blood causes vein collapse; In addition, when Severe edema, serious burn, life-threatening epilepsy, the ambulance rocked or the operating difficulties such as helicopter, dim light, intraosseous infusion has easy and simple to handle, fast and effeciently advantage, infusion channel can be set up in time, and apply salvage drug even infusion blood plasma, deshydremia cell etc., win the quality time for giving emergency treatment to a patient.
Puncture means common are at present manual rotation punctures and utilize spring or electric device automatic puncturing.But manual rotation mode not easily punctures for harder sclerotin, there is certain limitation.And automatic puncturing device is difficult to control trigger dynamics, because the sclerotin of human body is different, depth bounds is also difficult to control, and self-action puncture easily causes puncture complicated, increases operating difficulty, causes puncture needle failure, even occurs the risk of fracture and broken needle.Recent discovery, the method for hammering puncture has good application prospect clinically, is not only suitable for various sclerotin, and is conducive to healthcare givers and controls puncture dynamics.
But, be not applicable to the intraosseous infusion needle of hammering piercing method at present.Number of patent application is " CN201342184Y ", application number is " 200920079005.2 ", name is called that the utility model of " Manual intraosseous infusion needle " discloses a kind of conventional intraosseous infusion needle, comprise manual driver and puncture needle, puncture needle is trocar design, comprises puncture needle tubing and puncture needle core two parts composition.Puncture needle tubing is hollow-core construction, puncture needle core is solid, be positioned at the cavity of puncture needle tubing, the tip that the needle tip of puncture needle core passes the needle tubing that punctures closely is connected with the tip of puncture needle tubing, and the base of puncture needle tubing and the base of puncture needle core are by spiral interface compact siro spinning technology.When using this conventional transfusion needle to be penetrated by hammer mode, (1), owing to not helping a little, healthcare givers generally only can help hollow needle tubing, in hammering process, the impact that hollow needle tubing is subject to can affect the operation of healthcare givers; (2), hollow needle tube-surface easily skids.(3), help position to regulate and control, medical personnel help and a little usually determine according to personal habits, and hollow needle tubing available support position is limited and single, the efficiency of impact puncture and success rate.In addition, the puncture needle for hammer mode puncture is also absolutely necessary to restriction nook closing member in-position.Existing puncture needle cannot meet above requirement.
Now need a kind of intrabone infusion device going for hammer mode puncture badly.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of intrabone infusion device being beneficial to hammering puncture is provided, enable there is support position that is stable, that can regulate when hammering is punctured, and help position not by the impact that hollow puncture tube penetrates, effectively control the puncture needle degree of depth simultaneously.
In order to achieve the above object, this utility model provides a kind of intrabone infusion device, comprise handle, hollow needle tubing and nook closing member, described handle is fixed on nook closing member tail end, nook closing member is inserted in hollow needle tubing, also comprises pin cap and block, and block is fixed on nook closing member, make nook closing member form nook closing member front end and nook closing member rear end two parts, hollow needle tubing is connected with block; There is through hole at Zhen Mao center, is socketed on nook closing member rear end; Block restriction pin cap position, makes pin shade nook closing member move in nook closing member rear end.
The mode of pin cap adjusting position on nook closing member is the means that mechanical field is conventional, and comprise slideway etc., preferably, pin cap through hole has female thread, and there is external screw thread nook closing member rear end, and pin cap and nook closing member are threaded connection.Pin cap is by being rotated in the upright position on adjustment nook closing member.
Described nook closing member front end refers to that on nook closing member, block is to the part of needle point, and described nook closing member rear end refers to the part between block to handle.In literary composition, the front portion of other part indications refers to that rear portion refers to the direction deviating from needle point near nook closing member needle point direction.
Have cylindrical cavity bottom described pin cap, cavity inside diameter is greater than the external diameter of hollow needle tubing.When pin cap moves up and down, hollow needle tubing can be held in the lumen, make pin cap have longer moving range.
Intrabone infusion device arranges stop, and stop is taper, and there is depression bottom surface, is fixed on hollow needle tubing.The stop of intrabone infusion device is arranged on hollow needle tubing, and after transfusion completes, stop can also facilitate medical personnel's fixation hollow needle tubing as fixture.
Stop can also be fixed on pin cap leading section, also can play regulating action at metering needle cap to stop simultaneously.
Preferably, described handle main body is cheese, and both sides are connected with bar.The cheese of handle is used for knocking, and bar is for rotating transfusion device.
Preferably, nook closing member rear end length is 15-25mm.
Preferably, described hollow needle tubing there is liquid-leadage hole, prevent needle tubing front end from blocking, and increase the speed of transfusion, realize the object of rescue shock patient quick infusion clinically.
Preferably, described pin cap outer surface has several fins.Increase pin cap frictional force, be conducive to the stability of helping.
Preferably, described block and hollow needle tubing are threaded connection.
Puncture needle of the present utility model adds pin cap and block on prior art basis, pin cap can regulate vertical position between handle and block, add one to medical personnel can regulate and the support point departing from hollow needle tubing, overcome the shortcoming of not helping position of hammer mode puncture.Stop effectively can control paracentesis depth, prevents transition of puncturing.
The beneficial effects of the utility model are, provide the support position departing from hollow needle tubing, and effectively can regulate support position, increase puncture success rate, relieve patient ' s burden and pain.
