Abstract

The utility model discloses an intravenous injection hand model, which comprises a fist-shaped hand model body simulating the size of the hand of the human body, and a movable body, which is made of elastic soft material, is arranged in a triangular area at the middle of the opisthenar of the hand model body, and covers the anatomical position of superficial veins of the opisthenar; the hand model body is connected with the movable body through a connecting part, and a plurality of grooves simulating the depths and trends of different veins are arranged at the middle of the opisthenar of the hand model body. Compared with the prior ordinary intravenous injection model, the utility model is characterized by high repeated utilization rate, low cost, high vein simulation degree and visual puncture results, and can effectively solve problem that clinical intern nurses or analysts have little chance to practice vein puncture and cannot skillfully operate.

Description

The hand vein injection model

Technical field

The utility model relates to the clinical medical and nursing teaching aid, particularly intravenous injection exercise model.

Background technology

Under the restriction of multiple factors such as current doctor-patient relationship anxiety, legal provision, patient's degree of cooperation are low, usually make trainees such as clinical care, anesthesia, check take action on one's own to operate intravenous chance and reduce, reduce so that basic fundamentals such as venipuncture are grasped skill level.General clinical teaching and research room is furnished with the intravenous injection model, but this model costs an arm and a leg, generally being used for operating examination uses, student's availability is low, and vein blood vessel is single, in most cases only straight by trend, the low blood vessel of thick, the visual degree of caliber is formed, and can not reuse, thereby it is little that the student is improved the success ratio use of venipuncture.

The utility model content

The purpose of this utility model is single in order to overcome existing intravenous injection model vessel, can not effectively reflect true man's vascular condition, and can not reuse, the low defective of the expensive availability of model, but the hand vein injection model of a kind of simple, intuitive, low price repetitive operation is provided, carries out the venipuncture procedure exercise for medical personnel and student.

The technical solution of the utility model is: the hand vein injection model comprises the shape fingerprint body of clenching fist of a simulation human body size, delta-shaped region is provided with mobile at the back of the hand middle part of fingerprint body, mobile carries out and to cover at the back of the hand superficial vein anatomical position with top, makes with elastic soft material; The fingerprint body is connected by web member with mobile, and there is the groove of many different vein depths of simulation and trend at the back of the hand middle part of fingerprint body; Include the flexible pipe of simulating vein in described groove, the hose diameter size adapts with groove.

During use, the operator can be with flexible pipe as the simulation vein, one end is tightened, in pipe all or segmental inject red ink, perhaps other oily liquids is after tightening the other end and making its formation cecum, snap in the groove, close mobile again, user's simulated touch vein trend, the exercise of puncturing then.

Compare with existing general intravenous injection model, but the utlity model has the recycling rate of waterused height, cost is low, the characteristics of vein simulating degree height, venipuncture visual result can effectively solve the bedside practice nurse or docimaster's venipuncture chance is few, operate problems such as unskilled.Model mobile part is soft, can touch the vein trend.Groove is pressed close to true man's vein situation more, effectively improves the trainee at the feel heart sense when puncturing of different vein conditions.The trainee can utilize the simplest material can be in the exercise of each section office, and the blood vessel simulation material is simple and easy to, and with using with abandoning, has good practice significance, is fit to clinical expansion and uses.

Fig. 2 is the cut-open view of the utility model along Figure 1A A tangent line.

Embodiment

As shown in Figure 1, the shape fingerprint body 1 of clenching fist with dental stone or a simulation of plastic production human body size, delta-shaped region hollows out more than the back of the hand superficial vein anatomical position at the back of the hand middle part of fingerprint body 1, many grooves 3 are set therein, groove 3 simulation human body the back of the hand portion's vein depth and trends.In the part that hollows out mobile 2 is set, mobile's 2 usefulness elastic soft materials are made, and carry out the cut-out of covering more than the back of the hand superficial vein anatomical position.Fingerprint body 1 is connected with mobile 2, and body 1 and mobile's 2 two parts can be opened also can be closed, and this connection can be any connected mode in the present technical field, as radial type, buckled or the like.In embodiment as shown in Figure 2, adopt hinge 4 to connect, at opposite side bayonet socket 5 is set, make mobile 2 freely close and to open.

During use, the operator can be with any flexible pipe as the simulation vein.Flexible pipe as the simulation vein can adopt the woven hose of passing into disuse, or transfusion leather strap etc. serves as, one end is tightened whole or segmental injection red ink, perhaps other oily liquids in pipe, after tightening the other end and making it form cecum, snap in the groove 3, close mobile 2 again, by bayonet socket 5 chuckings, simulated touch vein trend, the exercise of puncturing then.Exercise finishes, and only needs abandoning with thing in the groove, continues to use and keep the hand model, can significantly reduce cost like this, improves the utilization factor of model, also greatly improves clinical band religion teacher's demonstration teaching work efficiency.

According to the different vein conditions of the built-in groove simulation of fingerprint type, the student can effectively experience true man's venipuncture characteristics and technical requirement.When the vein of filling with red ink was implemented to puncture successfully, just there was red ink at the needle point place, and puncture failure is then opposite.When segmental being injected the venipuncture success of red ink, see blood back and continue to move towards to continue parallel inserting needle along vein, can improve the self-confident degree of student's venipuncture like this.Can simulate the puncture at venous valve place at the vein crossings place, can allow the student learn how effectively to avoid the damage of venous valve.When puncture was full of oil-based liquid, student association was loseing how this continues inserting needle under the blood back situation.
