Abstract
The utility model relates to an infusion needle device capable of being prevented from damaging the inner wall of a blood vessel. The infusion needle device comprises a bevel-edge needle tube provided with a bevel-edge needle point that helps the bevel-edge needle tube to be stuck into a blood vessel conveniently, and is characterized in that a longer infusion needle tube is arranged in the bevel-edge needle tube in a penetrating manner; the needle head of the infusion needle tube is a rounded and smooth flat head so as to be prevented from damaging the wall of a blood vessel; and a positioning component is arranged between the rear side part of the bevel-edge needle tube and the rear side part of the infusion needle tube and can enable the bevel-edge needle tube and the infusion needle tube to be spliced and buckled conveniently. The infusion needle device has the advantages of simple structure, convenience in use, safety and reliability, and can completely avoid that during infusion, when the hand of a patient moves slightly, the wall of the blood vessel can be punctured by the needle point, so that the patient suffers from local swelling caused by the reason that liquid medicine permeates into muscles.
Description
Technical field
This utility model relates to field of medical technology, especially a kind of infusion needle device that prevents the injured blood vessel inwall.
Background technology
Every have a people who hung bottle, all can have an intimate knowledge, in case hang up bottle, syringe needle is fixed on the back of the hand, and patient can not voluntary activity, and is careless slightly, will cause swelling, makes the nurse change syringe needle again, looks for the blood vessel acupuncture treatment again, its painful oneself needless to say.Trouble is to find out some blood vessel calm hidden being difficult for, and can also increase the trouble that repeats to look for blood vessel to medical personnel simultaneously because the back of the hand swelling and can't implement to hang bottle brings difficulty to treatment.
Summary of the invention
The purpose of this utility model is to provide a kind of infusion needle device that prevents the injured blood vessel inwall, and this infusion needle apparatus structure is simple, esy to use, safe and reliable.In the time of can avoiding infusing fully, the due to illness slight activity of people's hand and the needle point that causes punctures blood vessel wall makes medicinal liquid infiltrate muscle and the misery of the local swelling that causes.
Of the present utility model being characterised in that: a kind of infusion needle device that prevents the injured blood vessel inwall, comprise and have the inclined blade needle point, penetrate a joint inclined blade needle pipe of blood vessel in order to it, it is characterized in that: be equipped with long Transfusion needle pipe in the described inclined blade needle pipe, the syringe needle of described Transfusion needle pipe is mellow and full slick tack, to prevent the syringe needle injured blood vessel wall of Transfusion needle pipe, be provided with the positioning component of pegging graft mutually and fastening between described inclined blade needle pipe rear lateral portion and the Transfusion needle pipe rear lateral portion in order to both.
It is reliable for two needle tubings can be located when infusing, described positioning component comprises fixed handle that is arranged on inclined blade needle pipe rear lateral portion and the position fixing handle that is arranged on the Transfusion needle pipe rear lateral portion, described fixed handle is provided with a tooth bar parallel with the inclined blade needle pipe, offer a through hole that is used to wear tooth bar on the described position fixing handle, described through-hole wall is provided with and cooperates the localized flank of tooth with tooth bar.
When the syringe needle of Transfusion needle pipe is pressed into blood vessel, be input to smoothly in the blood vessel in order to make the medicinal liquid in the Transfusion needle pipe, offer a little straight mouth on the syringe needle of described Transfusion needle pipe, and it is carried out abate handle.
Cooperate with other instillation assemblies for convenience, described Transfusion needle pipe rear end is connected with a bit of flexible pipe.
Advantage of the present utility model is: this infusion needle device can effectively avoid existing infusion needle to puncture the drawback of blood vessel wall easily, makes when hanging bottle, and the voluntary activity that patient's hands can be among a small circle can not cause leakage swelling yet.It is greatly convenient to have brought to patient, has alleviated suffering of illness, has also alleviated burden to medical personnel.

The specific embodiment
The infusion needle device that prevents the injured blood vessel inwall that this utility model is provided below in conjunction with accompanying drawing and specific embodiment is done and is specified.
The infusion needle device that prevents the injured blood vessel inwall of the present utility model, comprise and have the inclined blade needle point, penetrate a joint inclined blade needle pipe 1 of blood vessel in order to it, it is characterized in that: be equipped with long Transfusion needle pipe 2 in the described inclined blade needle pipe 1, the syringe needle of described Transfusion needle pipe 2 is mellow and full slick tack, to prevent the syringe needle injured blood vessel wall of Transfusion needle pipe, be provided with the positioning component 3 of pegging graft mutually and fastening between described inclined blade needle pipe 1 rear lateral portion and Transfusion needle pipe 2 rear lateral portion in order to both.
It is reliable for two needle tubings can be located when infusing, described positioning component 3 comprises fixed handle 31 that is arranged on inclined blade needle pipe 1 rear lateral portion and the position fixing handle 32 that is arranged on Transfusion needle pipe 2 rear lateral portion, described fixed handle 31 is provided with a tooth bar 33 parallel with inclined blade needle pipe 1, offer a through hole 34 that is used to wear tooth bar 33 on the described position fixing handle 32, described through hole 34 inwalls are provided with tooth bar 33 and cooperate the localized flank of tooth.
When the syringe needle of Transfusion needle pipe 2 is pressed into blood vessel,, offers a little straight mouth 4 on the syringe needle of described Transfusion needle pipe 2, and it is carried out abate handle for the medicinal liquid that makes 2 li of Transfusion needle pipes is input in the blood vessel smoothly.
Cooperate with other instillation assemblies for convenience, described Transfusion needle pipe rear end is connected with a bit of flexible pipe 5.
During use, can twitch syringe needle gently, the syringe needle of Transfusion needle pipe is withdrawn in the inclined blade needle pipe, the inclined blade needle point is exposed, when treating that syringe needle penetrates blood vessel and blood back is arranged, again Transfusion needle pipe is pushed, make the transfusion needle pipe range cross inclined blade needle pipe 5 ~ 10mm, make syringe needle unlikely blood vessel that injures in blood vessel of Transfusion needle pipe slyness, this moment the inclined blade needle point relatively the syringe needle of Transfusion needle pipe slyness withdrawn 5 ~ 10mm, how activity can not injure blood vessel wall and cause sepage swelling patient's arm.Therefore, safe and convenient, for patient has alleviated misery, also reduced workload to medical personnel.
This utility model does not limit to above-mentioned preferred forms, and anyone can draw other various forms of infusion needle devices that prevent the injured blood vessel inwall under enlightenment of the present utility model.All equalizations of being done according to this utility model claim change and modify, and all should belong to covering scope of the present utility model.
