Description

One is novel quantizes intravenous injection and puncture analog training device
Technical field
The invention belongs to clinical medicine and biomechanics field, relate to and a kind of novelly quantize intravenous injection and puncture analog training device.
Background technology
Intravenous injection and puncture are clinical commonly using and very important technological means, have damaging, easily patient pain is caused, if the misery of puncture failure meeting making patients, for children and old man in intravenous injection and piercing process, the injury caused is more remarkable, affect the treatment, for the rescue of urgent patient, one-time puncture success is most important, if misoperation, possible threat to life.Therefore, as medical personnel, skilled grasp intravenous injection and puncture technique very crucial.As a clinical technology, the raising of intravenous injection and puncture technique needs medical personnel to accumulate experience, but can not test with it patient.At present, have intravenous injection and puncturing pattern to practise puncture technique for medical personnel, due to such analog training device in process of the test without any feedback, be difficult to improve technical level; In order to improve injection and puncture level, there are part medical personnel to adopt worthless mode, use the vein of oneself to practise.
In intravenous injection and piercing process, because puncture force is very little, process of thrusting is very of short duration, and the size of puncture dynamics directly determines the pain degree of patient and the degree of injury to blood vessel.At present, do simulated exercises in intravenous injection and piercing process medical personnel, there is no the analog training device that can feed back puncture dynamics, be difficult to improve puncture gimmick, this problem urgently to be resolved hurrily.
Summary of the invention
The present invention is to overcome the deficiencies in the prior art, invention one is novel quantizes intravenous injection and puncture analog training device, overcome medical personnel to do simulated exercises in process without any feedback, be difficult to the defect of improving technical level, this analog training device can measure the situation of change of syringe needle puncture force in real time, help medical personnel to understand self-technique shortcoming, improve technical level.
In order to achieve the above object, technical scheme of the present invention is:
One is novel quantizes intravenous injection and puncture analog training device, comprises shell, syringe needle, block, connecting link, base and force snesor.
Described shell is divided into two parts, and a part has recessed, and a part has projection, and recessed and projection interlocks, and realizes assembling; The top of shell is cone-shaped body, a round hole is had above cone-shaped body, shell the first half is right cylinder, there is a through hole right cylinder side, the latter half is square body, and there is a through hole side of square body, and enclosure is emptied according to the shape of each part, for fixing internal part, have support, protective action concurrently.
Described syringe needle is metal material, and be placed in the round hole part of cover top portion cone-shaped body, syringe needle lower end is connected with syringe needle plastic pipe, and syringe needle has been used for injection and piercing process.
Described block is used for fixed needle, and be right cylinder, have the hole of up/down perforation, hole is divided into upper and lower two parts, and the first half aperture is greater than the metal tube external diameter of syringe needle, and the latter half aperture is less than the external diameter of the circular contour that connecting link upper end two intermediate plate is formed; By block through syringe needle, be enclosed within two intermediate plates, because the latter half aperture is less than the external diameter of the circular contour that two intermediate plates are formed, two intermediate plates are forced to produce elastic deformation, clamping syringe needle, the friction force that syringe needle and two intermediate plates produce is greater than puncture force, and when syringe needle punctures, puncture force is conducted to force snesor by connecting link.
Described connecting link is used for attachment force sensor and syringe needle, and transmit protection sensor while puncture force, connecting link is divided into three sections, and upper end is the right cylinder that there is space both sides that two pieces of symmetrical fan-shaped intermediate plates are formed, and stage casing is circular lattice gears, and lower end is threaded rod; The upper end intermediate plate of connecting link is for clamping syringe needle, syringe needle plastic pipe is derived by the space between two pieces of intermediate plates and shell the first half cylindrical sides through hole successively, be fixed on shell side, avoid the measurement of syringe needle plastic pipe Activity Effects puncture force, realize, while measurement puncture force, observing the blood back situation after venipuncture success simultaneously; Above the disk that the circular lattice gear in stage casing is installed on center drilling in shell the first half right cylinder within the scope of 0.1 ~ 1 millimeter; The threaded rod of lower end is connected with the threaded hole of force snesor upper end.
Described base is made up of circular base plate and whorl of base bar, and circular base plate is arranged in the rounded groove of shell the latter half square body, and whorl of base bar is connected with the threaded hole of force snesor lower end, for bed knife sensor.
Described force snesor is square body, be installed in shell the latter half square groove, fixed by base and shell, the two ends up and down of force snesor are threaded hole, the threaded hole of upper end is connected with the threaded rod of connecting link, the threaded hole of lower end is connected with whorl of base bar, and the side of force snesor is connected with force snesor wire, and the range of force snesor is 0 ~ 10N.
This analog training device measures the method for puncture force, be the mode adopting syringe needle to combine with force snesor, by force snesor, puncture force signal be converted to electric signal, then convert electrical signals to digital signal by digital transmitter, output to host computer, measure the size of puncture force in real time; This analog training device adopts the mode protection sensor of displacement restriction not to be damaged, and when needle displacement increases to a certain degree, circular lattice gear and the disk contact of center drilling, stop needle displacement to increase further.
Force snesor combines with syringe needle by the present invention; by connecting link, puncture force is conducted to force snesor; the size of puncture force can be measured in real time; the change of puncture force in the process of advancing after display syringe needle pricks blood vessel and penetrates blood vessel; inner structure defines the cephalomotor range of pin, and protection sensor is not damaged.Medical personnel hold this analog training device, in intravenous injection and the enterprising row vein injection of puncture arm models and puncture training process, the size of puncture force can be obtained, and the size of puncture force and the pain of patient proportional, medical personnel can by the action of adjustment oneself and the size of exerting oneself, reduce puncture force, reach best training effect.This analog training device enables to observe blood back situation while measurement puncture force by the special lead-out mode of syringe needle plastic pipe.Syringe needle can be demonstrated and prick the situation of change that blood vessel and syringe needle penetrate puncture force in multiple situation in blood vessel traveling process, than being observed by simple blood back and artificially feeling more effective, greatly help medical personnel to understand self-technique shortcoming, timely adjustment technology action, improve training effect.In addition, this analog training device shelling machine is small and exquisite, flexible, light, and shell the first half profile is similar to actual syringe needle, is convenient to medical personnel and the technical movements of grasp are transitioned into clinical practice from doing simulated exercises.
