Abstract

The utility model relates to an adult bone inner infusion device which belongs to the medical infusion device technique and comprises a puncture needle and a handle, wherein the puncture needle is thick and short and is designed according to the thickness of the sternum and the subcutaneous tissue of an adult. The puncture needle just reaches a marrow cavity and solves the problems of being not capable of controlling the dimension of inserting the needle and damaging a heart. The puncture needle is composed of a sheath pipe and a needle core, wherein a screw thread is arranged outside the sheath pipe and the phenomenon of a needle body of the infusion device sliding in the infusion is solved. The needle body length puncture needle is made of high-strength alloy and has no complication, such as breaking the needle, etc. The handle is provided with graduation and is convenient for mastering the depth of inserting the needle. The adult bone inner infusion device has the advantages that the use is convenient, the effect of the bone inner infusion and the administration is positive, a main body of the infusion device can be fixed and is caused not to easily slide and the dimension of inserting the needle can be controlled.

Description

Transfusion device in the adult bone

Technical field

This utility model belongs to medical infusion utensil technology, relates to a kind of utensil of the intraosseous infusion that is used to be grown up, especially for the critical first aid of adult patient, conveniently to carry out administration fluid infusion fast.

Background technology

Though the venous cannulation technology has been widely used in and has given emergency treatment to a patient, played sizable effect, but under the situation that particularly big at patient's whole body burn surface area in adult's first aid, serious dehydration, venous cannulation are difficult for, the venous cannulation first aid is difficulty relatively, can only carry out administration or fluid infusion with the intraosseous infusion device.

The mechanism of adult's intraosseous infusion is with the generation of breastbone and dissect relevant.In becoming human body, very poor because long bone bone marrow is converted into the yellow bone marrow that loses hemopoietic function by the red bone marrow with hemopoietic function to the absorbability of liquid, so long bone transfusion poor effect, can't set up infusion channel at long bone.Hemopoietic tissue only is confined to flat bone such as breastbone, ilium, clavicle etc., so the intraosseous infusion mode requires very high to choice of location.Speed and complexity with regard to puncture, it is comparatively suitable that the interior transfusion device site of puncture of adult bone is chosen at breastbone, breastbone bone angular vein passage still keeps opening to a certain degree when the periphery vein collapse, blood sinus has bigger permeability in the bone, therefore help most setting up infusion channel in the position of breastbone, this provides anatomic basis for be grown up intraosseous infusion and administration, also provides theoretical foundation for this utility model.

But there is following problem in the present intraosseous infusion device based on external production: 1, design is too complicated, uses very inconvenient.Transfusion device is formed by reaching ten several parts in some adult bone, obviously will incur loss through delay patient's rescue.2, the bad control of adult's bone marrow of sternum transfusion device on the market enters the degree of depth, and the possibility that this severe complication of heart damage takes place is arranged.3, transfusion device does not generally have fixture in the existing adult bone, and the time is long and all have sepage and transfusion needle sliding phenomenon when touching transfusion device accidentally in transfusion device is kept somewhere body.Therefore, the intraosseous infusion device that presses for a kind of adult of being applicable at present is used for rescuing adult's critical patient.

Summary of the invention

The purpose of this utility model is at existing intraosseous injection device above shortcomings, provide a kind of easy to use, intraosseous injection administering effect really, fixedly the transfusion device body, make it to be difficult for slip, can control the interior transfusion device of adult bone of inserting needle yardstick again.

The purpose of this utility model is achieved in that

Transfusion device in a kind of adult bone comprises puncture needle and handle two parts, and puncture needle is connected and fixed by syringe needle part and interface on the handle.Wherein puncture needle is made up of the sleeve pipe and the inner nook closing member of outside.Jacket exterior is a screw thread design, so just can make things convenient for medical personnel that needle body is thrust and the rotation of puncture needle body can be twisted as in the bone as the turn of the screw after skin arrives breastbone, and this helicitic texture and mode of operation can prevent that sliding and sepage from appearring in transfusion needle.Lancet design must be lacked and thick, and its length is according to adult's breastbone and soft tissue thickness decision, and the degree of depth that makes inserting needle in bone marrow of sternum, just can not take place breastbone is pierced through the danger that jeopardizes heart when puncture just like this.

In addition, puncture needle is made by high-strength alloy, when operation, the broken needle phenomenon can not occur.Be marked with scale at handle, so that grasp the degree of depth that enters of puncture needle.

Because this utility model adopted above structure, the especially puncture needle of tubbiness, outer threaded sleeve pipe and be with graduated handle design make in the adult bone of making transfusion device show particularly outstandingly aspect inserting needle yardstick and the stable transfusion device grasping.Transfusion device only is made up of two parts in this adult bone, and is simple in structure, reduced the difficulty of operation.

Description of drawings

Fig. 1 is the novel overall structure figure of this use;

Label among the above-mentioned figure refers to respectively: puncture needle 1, sleeve pipe 11, nook closing member 12, syringe needle part 13, screw thread 2, handle 3, scale 4, interface 5

The specific embodiment

Concrete structure of the present utility model is further provided by following embodiment and accompanying drawing thereof.

Referring to Fig. 1, transfusion device is made up of puncture needle 1 and handle 3 two parts in the adult bone.Its handle is the entity of a near cylindrical, wherein an end has a concave structure, be the interface 5 that is connected with puncture needle, the syringe needle part 13 of this concave structure and puncture needle fits like a glove, can by puncture needle syringe needle part 13 is stuck in reach easily in the concave structure puncture, rotation and fixed purpose.Puncture needle 1 is made up of the sleeve pipe 11 and the inner nook closing member 12 of outside, the comparatively tubbiness of whole lancet design, and the jacket exterior design has screw thread 2.Puncture needle adopts high-strength alloy to make, and can have multiple caliber different model, and the puncture needle syringe needle can connect standard syringe and tube for transfusion.In addition, on the transfusion device handle, be carved with scale 4, can grasp depth of needle whereby.

Using method of the present utility model is: puncture needle 1 is inserted in handle 3, aims at the chest position, firmly needle body is thrust subcutaneously by handle 3, and rotary handle screws in puncture needle in the bone marrow of sternum chamber by Power of Spin and helicitic texture.Nook closing member is extracted, connected syringe or tube for transfusion and can carry out administration transfusion in the bone.After treatment finishes, transfusion device or needle tubing are taken off, nook closing member is inserted prevent oozing of blood and pollution, with handle puncture needle is screwed out in the other direction and get final product.As seen, this product has simple in structure, convenience operation.
