Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.
Referring to fig. 1 to 3, an embodiment of the present invention provides a femoral vein puncture practice model, which includes an embedded dummy 100 having a shape of a lower limb of a human body, an arterial hose 300, a venous hose 400, a pump body, a liquid storage device, an inductive switch 200, an inductive sheet 220, and a vibration module 210; wherein, the artery hose 300 and the vein hose 400 are embedded in the embedding dummy 100; the pump body is respectively connected with the arterial hose 300 and the venous hose 400 and is used for inputting the liquid in the liquid storage device into the arterial hose 300 and the venous hose 400; the inductive switch 200 is connected with the inductive sheet 220, and specifically, the inductive sheet 220 is connected with the inductive sheet 220 through a conducting wire 900, and the inductive sheet 220 is coated on the side wall surface of the set area on the venous hose 400; the vibration module 210 is embedded in the embedded dummy 100, and the vibration module 210 is connected to the inductive switch 200, or specifically, may be connected to the inductive switch through a wire 900. Wherein the sensing strip 220 is disposed on the intravenous tube 400 at a location opposite the needle penetration point.
When the intravenous hose 400 is punctured, the position of the vein can be detected by ultrasonic technology, and the needle of the syringe can be accurately punctured into the intravenous hose 400, at this time, if the liquid in the intravenous hose 400 flows back into the syringe, the correct puncture position of the needle is indicated. However, if the needle is excessively inserted into the intravenous tube 400, the needle may penetrate the intravenous tube 400 and penetrate the embedded dummy 100 or the arterial tube 300, and at this time, the practitioner may erroneously determine that the puncturing operation is correct by observing the liquid flowing back from the syringe, and if such a situation frequently occurs, the practitioner may easily grasp an incorrect manipulation, which may lead to complications.
Therefore, in the embodiment, the sensing piece 220 is arranged on the venous hose 400 at a position opposite to the needle puncturing point, when the needle punctures the venous hose 400, the needle can contact the sensing piece 220, because the sensing piece 220 is connected with the sensing switch 200, the sensing switch 200 is automatically turned on after detecting a signal that the sensing piece 220 is contacted with the needle, the vibration module 210 is started, and because the vibration module 210 is embedded in the embedded dummy 100, the embedded dummy 100 can vibrate along with the vibration module 210, a practicer can timely realize that the venous hose 400 is punctured after feeling the vibration, thereby readjusting the puncturing method and ensuring the practicer to master the correct puncturing method.
Wherein, the embedding imitation body 100 can be provided with a puncture part, and the sensing piece 220 is arranged on one side surface of the intravenous hose 400 far away from the puncture part. Wherein, the puncture portion is the partial region of embedding imitation 100 facing the practitioner, and this puncture portion has limited the region that can carry out the puncture, if surpass this region, the puncture operation can not reach best effect, easily takes place to prick partially, puncture distance is not enough and prick other tissues next to the vein, causes patient's extra misery.

In addition, because the venous hose 400 is closer to the arterial hose 300, if the venous hose 400 is pierced and the needle head fails to contact the sensing strip 220 on the venous hose 400, the needle head may pierce into the arterial hose 300, and at this time, the practitioner may also misjudge that the operation is correct according to the liquid return phenomenon of the syringe in the venous hose 400; to avoid this, in this embodiment, the sensing piece 220 can be covered on all the side walls of the arterial tube 300 at the same time, so that when the needle contacts the sensing piece 220 on the arterial tube 300, the vibration module 210 is activated to indicate the error operation of the practicer.
Specifically, as shown in fig. 1, the pump body includes a first booster pump 600 and a second booster pump 800, and the liquid storage device includes a first liquid storage tank 500 and a second liquid storage tank 700; a liquid inlet of the first booster pump 600 is connected with the first liquid storage tank 500, a liquid outlet of the first booster pump 600 is connected with a liquid inlet of the arterial hose 300, and a liquid outlet of the arterial hose 300 is connected with a liquid return port on the first liquid storage tank 500; a liquid inlet of the second booster pump 800 is connected to the second liquid storage tank 700, a liquid outlet of the second booster pump 800 is connected to a liquid inlet of the intravenous hose 400, and a liquid outlet of the intravenous hose 400 is connected to a liquid return port of the second liquid storage tank 700. Thus, the arterial tube 300 and the venous tube 400 may be provided with pressures required to simulate normal blood circulation by the first booster pump 600 and the second booster pump 800, respectively.
Further, the embedded phantom 100 may include a skin layer, a fat layer, and a filling layer, which are sequentially stacked. The thicknesses of the skin layer, the fat layer and the filling layer are sequentially increased, and meanwhile, the hardness of the skin layer can be larger than that of the fat layer, so that the operation hand feeling of a practicer when using the practice model is closer to the human body, and an operator can be fully guaranteed to master correct operation skills.
Wherein, the skin layer, the fat layer and the filling layer can be made of one of thermoplastic polyurethane elastomer, silica gel or polyvinyl alcohol; specifically, in this embodiment, the skin layer and the fat layer are made of polyvinyl alcohol, and the filling layer is made of silicone, wherein the filling layer plays a role in supporting the fat layer and the skin layer.
It is understood that the material of each of the arterial tube 300 and the venous tube 400 may be silica gel or polyvinyl alcohol, and in this embodiment, the material of each of the arterial tube 300 and the venous tube 400 is polyvinyl alcohol.
The embodiment of the utility model provides a femoral vein puncture practice model is through setting up the response piece on the vein hose to and through setting up vibration module in the imitative body of embedding, realized after the syringe needle pierces through the vein hose, can trigger vibration module through the response piece and drive the imitative body vibration of embedding, thereby can make the practitioner experience can in time realize the maloperation after the vibration, and readjust the puncture gimmick, thereby guaranteed that the practitioner masters exact puncture gimmick, promoted clinical operation's the degree of accuracy.
