Background Technology

[0002] Arterial puncture is a medical procedure performed to analyze ventilation, gas exchange, oxygenation, and acid-base status through arterial blood gas analysis, and it is performed on the radial artery, brachial artery, and femoral artery. In addition, the femoral artery is the most widely used site as the most basic puncture site for performing angiography.

[0003] Methods for puncturing the femoral artery include puncturing based on the inguinal crease, puncturing based on the inguinal ligament attached to the anterior superior iliac spine and pubic tubercle among anatomical structures, puncturing by feeling the maximum pulse of the artery directly with a finger regardless of the inguinal crease, and puncturing using ultrasound.

[0004] The femoral vein is used when other long-term and stable venous catheters cannot be used, when peripheral insertion center catheters or intraosseous infusion are impossible, in cases of life-threatening conditions such as cardiac arrest or trauma, or when drawing blood or infusing fluids or medications into the vein.

[0005] Methods for puncturing the femoral vein include puncturing at the medial one-third of the location based on the inguinal ligament attached to the anterior superior iliac spine and pubic tubercle, locating it by inserting a needle 2 cm inward from the point of palpation after palpating the femoral artery pulse, and puncturing using ultrasound.

FIG. 6 is a control block diagram of the femoral artery and femoral vein puncture practice model shown in FIG. 1.

[0014] Referring to FIGS. 1 to 6, a femoral artery and femoral vein puncture practice model according to one embodiment of the present invention includes a thigh skin model (100), an injection pad (200), and a blood drive device (300).

[0015] In the thigh skin model (100), an inguinal crease line (111) is formed on the side of the left and right thighs (110). The left and right thighs (110) of the thigh skin model (110) are formed to resemble the appearance of the left and right thighs of an actual human body. In the thigh skin model (110), an injection pad mounting hole (120) is formed on one thigh (110). The injection pad mounting hole (120) allows the injection pad (200) to be attached and detached, thereby facilitating the maintenance and replacement of the injection pad (200).

[0016] The thigh skin model (100) can be formed to have a uniform thickness. The thigh skin model (100) can be made of an elastic material such as silicone or urethane that is similar in feel to the human body. The thigh skin model (100) has a flange formed along its edge, and the flange of the thigh skin model (100) can be fastened to the support (310) of the blood drive device (300) by bolting or the like. The flange of the thigh skin model (100) can be covered by a fixing bracket that is coupled to the upper part of the support (310).

[0017] The injection pad (200) is mounted in the injection pad mounting hole (120) of the thigh skin model (100). The injection pad (200) is detachably mounted in the injection pad mounting hole (120), making maintenance and replacement easy. The injection pad (200) is formed by sequentially stacking and bonding a lower support layer (210), a blood vessel layer (220), a fascia layer (230), and a skin layer (240). The injection pad (200) is formed by the lower support layer (210), the blood vessel layer (220), the fascia layer (230), and the skin layer (240) as a single unit.

[0018] The lower support layer (210) may be formed in the shape of a flat plate. The lower support layer (210) may have discharge grooves (211) for the support layer formed on each of its two edges to discharge leakage. The lower support layer (210) may be made of an elastic material such as silicone or urethane.

[0019] The blood vessel layer (220) can be bonded to the upper surface of the lower support layer (210) with an adhesive. The blood vessel layer (220) can be formed in a shape that mimics a portion of the blood vessel layer of an actual thigh. The blood vessel layer (220) may have blood vessel mounting holes (221) through which arterial blood vessels (250) and venous blood vessels (260) pass. The blood vessel layer (220) may have a blood vessel layer discharge groove (222) formed on each side wall, which communicates with the blood vessel mounting holes (221). The blood vessel layer discharge groove (222) may have an opening at the bottom and communicate with the support layer discharge groove (211) of the lower support layer (210). The blood vessel layer (220) may be made of an elastic material such as silicone, urethane, etc. The blood vessel layer (220) may have elasticity similar to that of an actual blood vessel layer.

[0020] The fascia layer (230) can be adhered to the upper surface of the blood vessel layer (220) in the form of a sheet having a uniform thickness. The fascia layer (230) can cover the entire upper surface of the blood vessel layer (220) with an area equal to that of the upper surface of the blood vessel layer (220). The fascia layer (230) can be formed from a self-healing elastic material, such as silicone gel, to minimize leakage of artificial blood during puncture practice on arterial blood vessels (250) and venous blood vessels (260).

[0021] The skin layer (240) can accommodate and cover the fascia layer (230), the blood vessel layer (220), and the lower support layer (210) in the internal space through the lower opening. The skin layer (240) can cover the drainage grooves (211) for the support layer of the lower support layer (210) and the drainage grooves (222) for the blood vessel layer of the blood vessel layer (220). The skin layer (240) can adhere the fascia layer (230) to the inner upper surface with an adhesive. The skin layer (240) may have holes on both side walls that allow arterial blood vessels (250) and venous blood vessels (260) to pass through. The skin layer (240) may be made of an elastic material such as silicone, urethane, etc.

[0022] The injection pad (200) has an arterial blood vessel (250) and a venous blood vessel (260) placed within the blood vessel layer (220). The arterial blood vessel (250) and the venous blood vessel (260) can be configured so as not to adhere to the blood vessel mounting holes (221) of the blood vessel layer (220). The arterial blood vessel (250) may have an outer diameter that forms a gap in the circumferential direction with the corresponding blood vessel mounting hole (221) of the blood vessel layer (220). The venous blood vessel (250) may also have an outer diameter that forms a gap in the circumferential direction with the corresponding blood vessel mounting hole (221) of the blood vessel layer (220).

[0023] These gaps can serve as passages for draining artificial blood that leaks from the arterial blood vessel (250) and the venous blood vessel (260) during puncture practice on the arterial blood vessel (250) and the venous blood vessel (260). The arterial blood vessel (250) and the venous blood vessel (260) can each be made of an elastic material hose, such as a silicone hose or a latex hose.

[0024] The injection pad (200) has an outlet (270) formed therein for discharging artificial blood that leaks through the gap between the arterial blood vessel (250) and the blood vessel layer (220) and the gap between the blood vessel (260) and the blood vessel layer (220) during puncture practice on the arterial blood vessel (250) and the venous blood vessel (260). The outlet (270) may be composed of a combination of a discharge groove (211) for the support layer of the lower support layer (210) and a discharge groove (222) for the blood vessel layer of the blood vessel layer (220).

[0025] The blood drive device (300) includes a support (310), a leaked blood recovery device, an arterial blood supply device, a venous blood supply device, and a controller (350). The support (310) supports a thigh skin model (100) and an injection pad (200), and a leaked blood collection part (316) is formed to collect artificial blood discharged from the outlet (270) of the injection pad (200).

[0026] On the upper part of the support (310), a thigh structure (311) similar to the external appearance of the left and right thighs of a real human body is formed to protrude and can be covered by the thigh skin model (100). On the upper part of the support (310), an artificial anterior superior iliac spine (312) and an artificial pubic tuberosity (313) are formed so that they can be punctured during puncture practice and can be covered by the thigh skin model (100). Therefore, when the practitioner punctures the thigh skin model (100) with their hand to locate the puncture positions of the arterial blood vessel (250) and the venous blood vessel (260), the anatomical structure can be easily identified.

[0027] The support member (310) may be made of a robust material, such as plastic. A housing (314) may be attached to the lower part of the support member (310) to mount a leaky blood recovery device, an arterial blood supply device, a venous blood supply device, and a controller (350). The housing (314) may be equipped with an input section (315) including various operation buttons for inputting user commands to the controller.

[0028] The support member (310) can support the injection pad (200) through a cover member (317) that is detachably attached to the upper side of the leakage blood collection section (316). A seating groove (317a) may be formed on the upper surface of the cover member (317) to seat and support the skin layer (240) and the lower support layer (210) of the injection pad (200). Ribs for reinforcement may be formed on the lower surface of the cover member (317). Connection holes (317b) may be formed on both edges of the cover member (317) to allow leakage blood to flow in from the discharge ports (270) of the injection pad (200) and discharge it to the leakage blood collection section (316).

[0029] The leakage blood collection part (316) may be formed in the shape of a recessed groove on the upper surface of the support member (310). The leakage blood collection part (316) may have a recovery hole (316a) in the center. The leakage blood collection part (316) is formed in a shape that slopes downward from the edge toward the center, thereby smoothly guiding the leakage blood discharged from the two connecting holes (317b) of the cover member (317) to the central recovery hole (316a).

[0030] The leaked blood recovery device recovers artificial blood collected in the leaked blood collection unit (316). For example, the leaked blood recovery device may include a recovery pipe (321), a leaked blood detection sensor (322), and a recovery pump (323). The recovery pipe (321), the leaked blood detection sensor (322), and the recovery pump (323) may be mounted within a housing (314) coupled to the lower part of the support (310).

[0031] The recovery pipe (321) recovers artificial blood collected from the leakage blood collection unit (316) into the arterial blood storage container (331). One opening end of the recovery pipe (321) may be connected to the recovery hole (316a) of the leakage blood collection unit (316), and the other opening end may be connected to the arterial blood storage container (331).

[0032] A blood leakage detection sensor (322) is installed in the recovery pipe (321) to detect artificial blood. The blood leakage detection sensor (322) can be composed of various known configurations, such as an optical sensor or a capacitive sensor. The blood leakage detection sensor (322) detects the presence or absence of artificial blood flowing in the recovery pipe (321) and provides this information to the controller (350). If the controller (350) determines that artificial blood leaked into the recovery pipe (321) is flowing based on the information detected by the blood leakage detection sensor (322), it can operate the recovery pump (323) to recover the leaked artificial blood into the arterial blood storage container (331).

[0033] A recovery pump (323) is installed in a recovery pipe (321) to transport artificial blood. The recovery pump (323) draws artificial blood from the leaked blood collection unit (316) into the recovery pipe (321) and sends it to an arterial blood storage container (331). The recovery pump (323) is driven by a controller (350). As another example, the recovery pipe (321) may also recover artificial blood collected from the leaked blood collection unit (316) into a venous blood storage container (341) or a separate leaked blood storage container.

[0034] An arterial blood supply device supplies artificial blood to an arterial blood vessel (250). For example, the arterial blood supply device may include an arterial blood storage container (331), an arterial blood supply pipe (332), an arterial blood return pipe (333), an arterial blood detection sensor (334), an arterial blood pump (335), a pressurizing unit (336), a bypass pipe (337), and a valve (338). In the arterial blood supply device, the arterial blood storage container (331) may be mounted on the outside of a housing (314), and the remaining components may be mounted on the inside of the housing (314).

[0035] The arterial blood storage container (331) stores artificial blood. The arterial blood storage container (331) may be made of a transparent material so that the practitioner can check the amount of artificial blood stored. The arterial blood supply tube (332) supplies artificial blood from the arterial blood storage container (331) to the arterial blood vessel (250). The arterial blood return tube (333) returns artificial blood from the arterial blood vessel (250) to the arterial blood storage container (331).

[0036] An arterial blood detection sensor (334) is installed in the arterial blood return tube (333) to detect artificial blood. The arterial blood detection sensor (334) may be configured similarly to a leakage blood detection sensor (322). The arterial blood detection sensor (334) detects the presence or absence of artificial blood flowing in the arterial blood return tube (333) and provides this information to the controller (350). Based on the information detected by the arterial blood detection sensor (334) during the initial operation of the arterial blood pump (335), the controller (350) can quickly fill the arterial blood supply tube (332), the arterial blood vessel (240), and the arterial blood return tube (333) with artificial blood, and then control the arterial blood pump (335) to create a pulse waveform in the arterial blood vessel (250).

[0037] An arterial blood pump (335) is installed in an arterial blood supply pipe (332) to transport artificial blood. The arterial blood pump (335) draws artificial blood from an arterial blood storage container (331), supplies it to an arterial blood vessel (250) via the arterial blood supply pipe (332), and then returns it from the arterial blood vessel (250) to the arterial blood storage container (331) via the arterial blood return pipe (333). The arterial blood pump (335) is driven by a controller (350). The controller (350) can control the arterial blood pump (335) to pulsate and supply it to the arterial blood vessel (250), thereby enabling the realization of a pulse waveform. The controller (350) can control the pulse intensity and pulse rate realized in the arterial blood vessel (250).

[0038] The arterial blood pump (335) can be configured to switch the direction of transport of artificial blood by forward rotation and reverse rotation depending on the operating mode and drain mode. When the arterial blood pump (335) rotates forward, it sucks artificial blood from the arterial blood storage container (331) and sends it to the arterial blood vessel (250), and when the arterial blood pump (335) rotates reverse, it sucks artificial blood from the arterial blood vessel (250) and sends it to the arterial blood storage container (331).

[0039] The pressurizing part (336) is installed in the arterial blood return tube (333) to increase the pressure of the arterial blood vessel (250). The pressurizing part (336) may include a tube with an orifice installed therein or a tube having an inner diameter smaller than that of the arterial blood vessel (250). The pressurizing part (336) can relatively increase the pressure of the arterial blood vessel (250) by reducing the cross-sectional area of ​​the passage through which artificial blood passes in the arterial blood return tube (333) and thereby lowering the pressure of the artificial blood.

[0040] That is, the pressurizing part (336) can increase the pressure of the arterial blood vessel (250) relatively by increasing the flow resistance of the artificial blood discharged from the arterial blood vessel (250). Accordingly, the practitioner can check for backflow of artificial blood during puncture practice on the arterial blood vessel (250). In addition, the practitioner can feel blood pressure and waveforms similar to those of the actual human body generated when connected to the arterial blood gas analysis device.

[0041] The bypass tube (337) branches off from the arterial blood return tube (333) between the arterial blood vessel (250) and the pressurizing section (336) and communicates with the arterial blood storage container (331). The bypass tube (337) allows artificial blood discharged through the arterial blood vessel (250) during the washing mode to bypass the pressurizing section (336) and return to the arterial blood storage container (331), and eliminates the flow load of artificial blood caused by the pressurizing section (336) during the drain mode, thereby improving the durability of the arterial blood vessel (250).

[0042] The valve (338) opens and closes the bypass pipe (337). The valve (338) operates to close the bypass pipe (337) in the operating mode, and operates to open the bypass pipe (337) in the washing mode and drain mode. The valve (338) may be a solenoid valve that operates by the solenoid principle.

[0043] A venous blood supply device supplies artificial blood to a venous blood vessel (260). For example, the venous blood supply device may include a venous blood storage container (341), a venous blood supply pipe (342), a venous blood return pipe (343), a venous blood detection sensor (344), and a venous blood pump (345). In the venous blood supply device, the venous blood storage container (341) is mounted on the outside of the housing (314), and the remaining components may be mounted on the inside of the housing (314).

[0044] The venous blood storage container (341) stores artificial blood. The venous blood storage container (341) may be made of a transparent material so that the practitioner can check the amount of artificial blood stored. The venous blood supply tube (342) supplies artificial blood from the venous blood storage container (341) to the venous blood vessel (260). The venous blood return tube (343) returns artificial blood from the venous blood vessel (260) to the venous blood storage container (341).

[0045] A venous blood detection sensor (344) is installed in the venous blood return pipe (343) to detect artificial blood. The venous blood detection sensor (344) may be configured similarly to an arterial blood detection sensor (334). The venous blood detection sensor (344) detects the presence or absence of artificial blood flowing in the venous blood return pipe (343) and provides this information to the controller (350). Based on the information detected by the venous blood detection sensor (344) during the initial operation of the venous blood pump (345), the controller (350) can quickly fill the venous blood supply pipe (342), the venous blood vessel (260), and the venous blood return pipe (343) with artificial blood, and then control the venous blood pump (345) to make the artificial blood flow into the venous blood vessel (260) at a set flow rate.

[0046] A venous blood pump (345) is installed in a venous blood supply pipe (342) to transport artificial blood. The venous blood pump (345) draws artificial blood from a venous blood storage container (341), supplies it to a venous blood vessel (260) via the venous blood supply pipe (342), and then returns it from the venous blood vessel (260) to the venous blood storage container (341) via the venous blood return pipe (343). The venous blood pump (345) is driven by a controller (350). The controller (350) controls the venous blood pump (345) to regulate the speed of the artificial blood flowing through the venous blood vessel (260), thereby enabling practice in monitoring blood flow velocity using ultrasound.

[0047] The venous blood pump (345) can be configured to allow the direction of transport of artificial blood to be changed by forward rotation and reverse rotation depending on the operating mode and drain mode. When the venous blood pump (345) rotates forward, it sucks artificial blood from the venous blood storage container (341) and sends it to the venous blood vessel (260), and when the venous blood pump (345) rotates reverse, it sucks artificial blood from the venous blood vessel (260) and sends it to the venous blood storage container (341).

[0048] The controller (350) controls the leak blood recovery device, the arterial blood supply device, and the venous blood supply device. The controller (350) can control the arterial blood pump (335) and the venous blood pump (345) according to commands input from the practitioner through the input unit (315).

[0049] The input unit (315) may be configured to receive commands from a trainee, such as setting the operating mode, setting the washing mode, setting the drain mode, and setting the power on / off, through the operation buttons. The input unit (315) may be mounted on the housing (314) with the operation buttons exposed to the outside. A lamp or display device that visually indicates the operation status of the operation buttons may be provided around the input unit (315).

[0050] The controller (350) can clean the arterial blood pump (335) and the venous blood pump (345) by controlling their forward rotation during the cleaning mode to continuously supply cleaning water to the arterial blood vessel (250) and the venous blood vessel (260). At this time, after the artificial blood in the arterial blood storage container (331) and the venous blood storage container (341) is removed, the cleaning water can be filled into the arterial blood storage container (331) and the venous blood storage container (341) and used. Purified water, etc., may be used as the cleaning water.

[0051] As such, according to the femoral artery and femoral vein puncture practice model of the present embodiment, it is possible to realistically train in arterial puncture practice, such as collecting arterial blood through the femoral artery and inserting an arterial catheter, and to realistically train in venous puncture practice, such as collecting venous blood through the femoral vein and securing a venous access. As a result, it can contribute to the practitioner accurately and skillfully performing arterial and venous punctures on a real human body.

[0052] The present invention has been described with reference to an embodiment illustrated in the accompanying drawings, but this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims. Explanation of the symbols
