Description

Technical Field

[0001] The utility model specifically relates to a trauma simulation hemostasis teaching device. Background Art

[0002] Blood is an important substance for maintaining life. When an adult loses more than 800 ml of blood, the victim may have pale face and lips, cold sweat on the skin, cold and weak hands and feet, rapid breathing, and a fast and weak pulse. If the amount of bleeding reaches more than 40% of the total blood volume, severe shock symptoms may occur, which may endanger life at any time, so it is particularly important to stop the bleeding of the wound in time.

[0003] At present, wound hemostasis is mostly achieved by pressure bandage hemostasis, which involves applying sterile gauze or clean handkerchiefs, towels, etc. to the wound, and then folding a triangular bandage or handkerchief into a belt and wrapping it around the injured limb to tighten and tie a knot, applying a certain amount of pressure to the wound to stop bleeding. However, wound hemostasis requires a certain level of proficiency to stop bleeding in the shortest time and minimize blood loss, so it is necessary to conduct simulated teaching of wound hemostasis.

[0004] The Chinese utility model patent No. 202122822679.0 provides a new teaching limb trauma hemostasis device. The device can simulate bleeding at the simulated wound through the setting of the blood simulation component. At the same time, the tourniquet, rotating rod and muscle module are used in conjunction for students to practice hemostasis. The medical waste generated during the practice can be centrally stored under the action of the storage component, thereby achieving the purpose of high simulation realism and controllable simulated bleeding volume.

[0005] However, after the existing trauma simulation hemostasis teaching aids perform hemostasis simulation, the wound is mostly covered by gauze or tourniquet, and the hemostasis effect cannot be intuitively known, resulting in a decrease in teaching effect. Therefore, in view of this, a trauma simulation hemostasis teaching device is proposed to solve the above problem. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model proposes a trauma simulation hemostasis teaching device to solve the technical problem raised in the above background technology that the existing trauma simulation hemostasis teaching aids are not convenient for intuitively knowing the hemostasis effect, thereby resulting in a decrease in teaching effect.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions, a trauma simulation hemostasis teaching device, comprising:

[0008] Receiver shell;

[0009] A limb model is arranged on the receiving shell, the limb model is made of silicone material, a simulated wound is opened on the limb model, and a drainage hole connected to the simulated wound is opened at the bottom;

[0010] A liquid inlet pipe and a liquid outlet pipe are both arranged in the limb model, one end of the liquid inlet pipe and the liquid outlet pipe respectively extends into two sides of the simulated wound, and the other end extends out of the limb model;

[0011] A liquid extraction assembly, disposed at one end of the liquid inlet pipe and connected thereto; and

[0012] The measuring component is arranged at one end of the liquid outlet pipe and communicated with the liquid outlet pipe.

[0013] In a preferred embodiment, a support frame is provided on the receiving shell, and the limb model is detachably arranged in the support frame.

[0014] In a preferred embodiment, the liquid extraction component includes:

[0015] a liquid extraction tube connected to an end of the liquid inlet tube extending outside the limb model; and

[0016] The liquid pump is arranged on the liquid pumping tube.

[0017] In a preferred embodiment, a liquid storage frame is provided on the receiving shell, and the end of the liquid extraction tube extends into the liquid storage frame.

[0018] In a preferred embodiment, the measuring component comprises:

[0019] a measuring cylinder, arranged at one end of the limb model and connected to one end of the liquid outlet tube extending outside the limb model, and having scale lines arranged along its axis; and

[0020] The liquid discharge valve is arranged at the bottom of the measuring cylinder.

[0021] In a preferred embodiment, mounting plates are provided on both sides of the inner wall of the simulated wound, both ends of the mounting plates are connected by elastic parts, and connecting seats are provided on the mounting plates. Multiple groups of the connecting seats are respectively connected to the ends of the liquid inlet pipe and the liquid outlet pipe.

[0022] In a preferred embodiment, a sealing gasket is provided on one side of the connecting seat located in the simulated wound.

[0023] In a preferred embodiment, a drain pipe is provided on the receiving shell.

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] When the device is in use, wound hemostasis simulation can be performed on a limb model. After the simulated wound is subjected to the simulated hemostasis action, the liquid can be extracted into the liquid inlet tube through the liquid extraction component. After the hemostasis action is performed, the liquid inlet tube and one end of the liquid outlet tube in the simulated wound are connected. The liquid entering the liquid inlet tube can flow out through one end of the liquid outlet tube. If the wound hemostasis force is insufficient or the wound is misplaced, the liquid cannot fully flow into the liquid outlet tube. By observing the volume of the liquid in the measurement component per unit time, it can be intuitively known whether the simulated hemostasis of the wound meets the standard, and then the hemostasis effect can be clearly known, thereby improving the teaching effect.

[0035] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0036] Example:

[0037] like Figure 1 , 2As shown, the utility model provides a trauma simulation hemostasis teaching device, including a receiving shell 101, a support frame 104 is provided on the receiving shell 101, a limb model 105 is detachably provided in the support frame 104, and the limb model 105 can be made of silicone material to realistically simulate an injured limb. A simulated wound 106 is provided on the limb model 105, and a drainage hole connected to the simulated wound 106 is provided at the bottom. When performing simulation teaching, simulated hemostasis can be performed on the simulated wound 106, and the limb models 105 of different shapes can be replaced as needed. During the simulated hemostasis process, the liquid in the simulated wound 106 can be discharged into the receiving shell 101 through the drainage hole. A drainage pipe 103 is provided on the receiving shell 101, and the liquid in the receiving shell 101 can be discharged through the drainage pipe 103.

[0038] like Figure 1 , 2 As shown, in this embodiment, a liquid inlet pipe 301 and a liquid outlet pipe 401 are provided in the limb model 105, one end of the liquid inlet pipe 301 and the liquid outlet pipe 401 are respectively extended into the two sides of the simulated wound 106, and the other end extends out of the limb model 105, and one end of the liquid inlet pipe 301 is provided with a liquid extraction component connected thereto, and the liquid extraction component includes a liquid extraction pipe 302 connected to one end of the liquid inlet pipe 301 extending out of the limb model 105, and a liquid extraction pump 303 is provided on the liquid extraction pipe 302. A liquid storage frame 102 is provided on the receiving shell 101, and the end of the liquid extraction pipe 302 extends into the liquid storage frame 102.

[0039] After the simulated hemostasis of the wound is performed, the liquid in the liquid storage frame 102 can be extracted into the liquid inlet pipe 301 through the liquid pump 303. When the simulated hemostasis of the wound meets the standards, the liquid inlet pipe 301 and one end of the liquid outlet pipe 401 in the simulated wound 106 are connected, and the liquid can enter the liquid outlet pipe 401 and be discharged from the limb model 105 through the liquid outlet pipe 401. When the simulated hemostasis of the wound occurs due to wound dislocation or insufficient hemostasis pressure, the liquid cannot completely enter the liquid outlet pipe 401, and is then discharged into the receiving shell 101 through the drainage hole.

[0040] like Figure 1 , 2 As shown, in this embodiment, a measuring component connected to the liquid outlet tube 401 is provided at one end thereof, and the measuring component includes a measuring cylinder 402 provided at one end of the limb model 105, and the measuring cylinder 402 is connected to the end of the liquid outlet tube 401 extending outside the limb model 105, and scale lines 403 are arranged on the measuring cylinder 402 along its axis, and a drain valve 404 is provided at the bottom of the measuring cylinder 402.

[0041] After the simulated hemostasis of the wound, the liquid in the liquid outlet tube 401 is discharged into the measuring tube 402. The volume of the discharged liquid can be known through the scale line 403 on the measuring tube 402. Then, by observing the volume of liquid discharged into the measuring tube 402 per unit time, it can be known whether the simulated hemostasis of the wound has reached the standard, thereby improving the accuracy of teaching.

[0042] like Figure 2 , 3 As shown, in this embodiment, mounting plates 201 are provided on both sides of the inner wall of the simulated wound 106, both ends of the mounting plates 201 are connected by elastic members 202, and connecting seats 203 are provided on the mounting plates 201. Multiple groups of connecting seats 203 are respectively connected to the ends of the liquid inlet pipe 301 and the liquid outlet pipe 401. A sealing gasket 204 is provided on one side of the connecting seat 203 located inside the simulated wound 106.

[0043] Under the action of the elastic member 202, the two sets of mounting plates 201 are in an open state, and the elastic member 202 allows the wound to be more consistent with the actual injury state to improve the authenticity of the simulation. The connecting seat 203 is used to install the liquid inlet pipe 301 and the liquid outlet pipe 401. Under the action of the sealing gasket 204, liquid leakage can be avoided when the wound simulation hemostasis meets the standard, thereby improving the teaching effect of the device.

[0044] Specific usage and beneficial effects of the utility model:

[0045] When the device is in use, wound hemostasis simulation can be performed on the limb model 105. After the simulated wound 106 is subjected to the simulated hemostasis action, the liquid can be extracted into the liquid inlet tube 301 through the liquid extraction pump 303 in cooperation with the liquid extraction tube 302. After the hemostasis action, the liquid inlet tube 301 and one end of the liquid outlet tube 401 in the simulated wound 106 are connected. The liquid entering the liquid inlet tube 301 can flow out through one end of the liquid outlet tube 401. If the wound hemostasis force is not enough or the wound is misplaced, the liquid cannot fully flow into the liquid outlet tube 401. By observing the volume of the liquid in the measuring tube 402 per unit time, it can be intuitively known whether the simulated hemostasis of the wound meets the standard, and then the hemostasis effect can be clearly known, thereby improving the teaching effect.

[0046] The basic principle and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
