Description
Technical field
The invention belongs to clinical medicine and biomethanics field, it is related to a kind of new quantify to be injected intravenously and puncture simulation
Trainer.
Background technology
Intravenous injection and puncture are clinical conventional and very important technological means, with damaging, be injected intravenously and wear
Easily cause patient pain during thorn, if the pain of puncture failure meeting making patients, for children and old man, the wound for causing
Evil is more significantly, affects the treatment, and for the rescue of urgent patient, one-time puncture success is most important, if misoperation, can
Can threat to life.Accordingly, as medical personnel, skilled grasp intravenous injection and puncture technique are very crucial.As a clinic
Technology, intravenous injection and the raising of puncture technique need medical personnel to accumulate experience, but can not be tested with patient.At present,
There are intravenous injection and puncturing pattern to practise puncture technique for medical personnel, because such analog training device does not have in process of the test
There is any feedback, it is difficult to improve technical level；In order to improve injection and puncture level, there are part medical personnel using worthless
Mode, the vein using oneself is practised.
In intravenous injection and puncture process, because puncture force is very small, piercing process is very of short duration, punctures the size of dynamics
Directly determine the pain degree and the degree of injury to blood vessel of patient.At present, done simulated exercises in medical personnel and be injected intravenously and wear
During thorn, without the analog training device that can feed back puncture dynamics, it is difficult to improve and puncture gimmick, it would be highly desirable to solve this and ask
Topic.
The content of the invention
The present invention is that invention one kind is new to be quantified to be injected intravenously and puncture simulation instruction in order to overcome the deficiencies in the prior art
Practice device, overcome medical personnel there is no any feedback during doing simulated exercises, it is difficult to the defect improved technical level, simulation instruction
Practice the situation of change that device can in real time measure syringe needle puncture force, help medical personnel to understand itself technical disadvantages, improve skill
Art level.
In order to achieve the above object, the technical scheme is that：
One kind is new to be quantified to be injected intravenously and puncture analog training device, including shell, syringe needle, block, connecting rod, bottom
Seat and force snesor.
The shell is divided into two parts, and a part has recessed, and a part has a projection, it is recessed and it is raised interlock, realize assembling；
The top of shell is bullet, and there is a round hole bullet top, and shell top half is cylinder, and cylinder side has one
Individual through hole, the latter half is square body, and there is a through hole side of square body, and enclosure is carried out according to the shape of each part
Empty, for fixing internal part, have support, protective action concurrently.
The syringe needle is metal material, is placed in the round hole part of cover top portion bullet, and syringe needle lower end is moulded with syringe needle
Sebific duct is connected, and syringe needle is used to complete injection and puncture process.
The block is used for fixed needle, is cylinder, is provided with the hole of up/down perforation, and hole is divided into upper and lower two parts, upper half
, more than the metal tube external diameter of syringe needle, the latter half aperture is less than the circular contour that the intermediate plate of connecting rod upper end two is formed for part aperture
External diameter；Block is passed through into syringe needle, is enclosed within two intermediate plates, by the latter half aperture is less than the circular contour that two intermediate plates are formed
External diameter, force two intermediate plates to produce elastic deformation, clamp syringe needle, the frictional force that syringe needle and two intermediate plates are produced more than puncture force, when
When syringe needle is punctured, puncture force is conducted to force snesor by connecting rod.
The connecting rod is used to connect force snesor and syringe needle, and force snesor, connecting rod are protected while transmission puncture force
It is divided into three sections, upper end is the cylinder that there is space the both sides that two pieces of symmetrical fan-shaped intermediate plates are formed, stage casing is circular lattice gear, lower end
It is threaded rod；The upper end intermediate plate of connecting rod is used to clamp syringe needle, syringe needle plastic pipe pass sequentially through space between two pieces of intermediate plates and
Shell top half cylindrical sides through hole is derived, and is fixed on shell side, it is to avoid syringe needle plastic pipe activity influence puncture force
Measurement, while realizing while puncture force is measured, the blood back situation after observation venipuncture success；The circular lattice gear peace in stage casing
In the range of 0.1~1 millimeter of the disk top loaded on center drilling in shell top half cylinder；The threaded rod of lower end is passed with power
The screwed hole of sensor upper end is connected.
The base is made up of circular base plate and whorl of base bar, and circular base plate is arranged on shell the latter half square body
In rounded groove, whorl of base bar is connected with the screwed hole of force snesor lower end, for fixing force snesor.
The force snesor is square body, is installed in the square groove of shell the latter half, is fixed with shell by base,
The upper and lower ends of force snesor are threaded hole, and the screwed hole of upper end is connected with the threaded rod of connecting rod, the screwed hole of lower end
It is connected with whorl of base bar, the side of force snesor is connected with force snesor wire, the range of force snesor is 0~10N.
The analog training device measure puncture force method, be using syringe needle by the way of force snesor is combined, pass through
Force snesor is converted to electric signal by force signal is punctured, then converts electrical signals to data signal by digital transmitter, exports
To host computer, the size of puncture force is measured in real time；The analog training device protects force snesor by the way of displacement limitation
Without damage, when needle displacement increases to a certain extent, the disk contact of circular lattice gear and center drilling prevents needle displacement
Further increase.
With syringe needle be combined force snesor by the present invention, and puncture force is conducted into force snesor, Ke Yishi by connecting rod
When measurement puncture force size, display syringe needle prick blood vessel and penetrate advance after blood vessel during puncture force change, it is internal
Structure qualification pin cephalomotor range, protection force snesor is without damage.Medical personnel hold the analog training device,
In being injected intravenously and puncturing the enterprising row vein injection of arm models and puncture training process, the size of puncture force can be obtained,
And the size of puncture force is proportional with the pain of patient, medical personnel can by adjust oneself action and firmly size,
Reduce puncture force, reach optimal training effect.The analog training device is made by the special lead-out mode of syringe needle plastic pipe
Blood back situation can be observed while measurement puncture force.Can show that syringe needle pricks blood vessel and syringe needle penetrates blood vessel traveling process
In it is various in the case of puncture force situation of change, than by simple blood back observe and artificially feel more efficient, greatly help
Medical personnel are helped to understand itself technical disadvantages, timely adjustment technology action improves training effect.In addition, the analog training device
Shelling machine is compact, flexible, light, and shell top half profile is similar to actual syringe needle, the skill for being easy to medical personnel to grasp
Art action is transitioned into clinical practice from doing simulated exercises.
