Abstract
Description
Bone needle puncture training device Technical Field
[0001] This invention relates to a teaching and training device, and more particularly to a bone needle puncture training device that provides personnel with practice in bone needle puncture. Prior Technology
[0002] When it is impossible to administer medication and the corresponding dosage to a patient through peripheral intravenous injection, personnel often use bone needle puncture for injection. This method connects the venous system through the bone marrow interstitium, allowing the patient to receive the required type and dosage of medication. This is especially useful for patients in life-threatening situations, such as trauma patients, burn patients, patients in shock, patients with small blood vessels, or patients at emergency scenes. Therefore, when peripheral intravenous injection cannot be established quickly, bone needle injection can be considered.
[0003] Furthermore, bone needles directly puncture the bone marrow cavity to establish an infusion and drug delivery pathway, allowing medication to quickly enter the circulatory system. This is particularly useful in emergency situations where there are frequent incidents. As an alternative to bone needle injection, it can quickly establish and connect the patient's peripheral venous system with a high success rate, thereby increasing the patient's survival rate. Therefore, it is necessary to provide a training device for bone needle puncture practice to train relevant personnel and overcome any knowledge gaps. Summary of the Invention
[0004] The purpose of this invention is to provide a bone needle puncture training device that allows medical personnel to practice bone puncture and liquid injection using bone needles.
[0005] To achieve the above objectives, this invention provides a bone needle puncture training device for medical personnel to practice bone puncture and fluid injection using bone needles. The device mainly comprises a first bone unit, a second bone unit, a fluid reservoir, and a skin unit. One end of the first bone unit is provided with a first connecting unit, and a first cavity unit is provided inside it. The first cavity unit forms a first connection port at the end of the first connecting unit. One end of the second bone unit is provided with a second connecting unit to assemble the first connecting unit. The skeletal unit is provided with a second cavity unit, wherein the second cavity unit is adjacent to the end of the second connecting unit and is provided with a second connecting port, and its other end is provided with a third connecting port; one end of the liquid storage unit is connected to the third connecting port; and the skin unit is covered on the outer periphery of the first skeletal unit and the second skeletal unit; wherein the first connecting port is connected to the second connecting port, so that the first cavity unit is connected to the second cavity unit, and when the bone needle is punctured into the first cavity unit for injection, the liquid injected by the bone needle will flow from the first cavity unit through the second cavity unit to the liquid storage unit.
[0006] Furthermore, the first skeletal unit and the second skeletal unit are shaped like the proximal humerus, and a first feature unit is provided on the outer periphery of the first skeletal unit.
[0007] Furthermore, the first connection unit is provided with a first guide unit adjacent to the first connection port end.
[0008] Furthermore, the first guiding unit gradually tapers toward the first connection port.
[0009] Furthermore, the second connection unit is provided with a second guide unit adjacent to the second connection port end.
[0010] Furthermore, the second guide unit gradually expands toward the second connection port, and the second guide unit abuts against the corresponding first guide unit.
[0011] Furthermore, the first connecting unit protrudes from one end of the first bone unit toward the second connecting unit of the second bone unit, so that the first connecting unit is assembled on the second connecting unit.
[0012] Furthermore, a locking fastener is provided at the first connecting unit of the first bone unit and the second connecting unit of the assembled second bone unit, the locking fastener locking the second bone unit to the first bone unit.
[0013] Furthermore, the first skeletal unit is made of a light-transmitting material.
[0014] Furthermore, the first skeletal unit has a tendon unit on the other side opposite to the first feature unit. The tendon unit is electrically connected to an alarm processing unit. When the bone needle contacts the tendon unit, the alarm processing unit receives and processes the signal returned by the tendon unit and generates an alarm signal.
[0015] The bone needle puncture training device of this invention mainly involves assembling the first connecting unit of the first bone unit onto the second connecting unit of the second bone unit, and locking the first bone unit to the second bone unit with the locking fastener. The first cavity unit connects to the second connecting port via the first connecting port, and the first cavity unit connects to the second cavity unit and the fluid storage unit. The skin unit covers the assembled first and second bone units, allowing the user to practice through the first feature unit. The device determines the acupuncture point of the bone needle. Once the bone needle has completed the puncture of the first bone unit, an infusion is injected into the first cavity unit. After entering the first cavity unit, the infusion flows through the second cavity unit to the reservoir unit. The first bone unit can be replaced as needed to allow other users to practice bone needle puncture. Thus, the bone needle puncture training device of this invention not only provides realistic teaching and training, but also makes it more convenient to use by replacing the first bone unit that has been trained.

Furthermore, the figures in this work are not necessarily drawn to actual scale for illustrative purposes, and the scale in the figures is not intended to limit the scope of protection sought for this work.
[0018] Regarding the technology of this invention, please refer to Figures 1 to 4. This invention provides a bone needle puncture training device 100 for training medical personnel to perform punctures and fluid injections using bone needles 200. The bone needle puncture training device 100 mainly includes:
[0019] A first skeletal unit 10 has a first connecting unit 11 protruding from one end and a first cavity unit 12 inside it. The first cavity unit 12 forms a first connection port 13 at the end of the first connecting unit 11. The first connecting unit 11 has a first guiding unit 111 that tapers toward the first connection port 13 at the end adjacent to the first connection port 13. In this embodiment, the first skeletal unit 10 is a part of the proximal humerus. A first feature unit 14 is provided on the outer periphery of the first skeletal unit 10. The first skeletal unit 10 is made of a light-transmitting material, but is not limited thereto.
[0020] A second skeletal unit 20 is provided at one end with a second connecting unit 21 to assemble the first connecting unit 11. The second skeletal unit 20 also has a second cavity unit 22. In this embodiment, the second skeletal unit 20 is a portion of the proximal humerus, and the first skeletal unit 10 and the second skeletal unit 20 are combined in this proximal humerus, but this is not a limitation. The second cavity unit 22 is adjacent to the end of the second connecting unit 21 and has a second connection port 23. The second connecting unit 21 has a first connection port 23 at the end adjacent to the second connection port 23. The second guide unit 211 gradually expands toward the second connection port 23 and abuts against the corresponding first guide unit 111. The first connection unit 11 protrudes from one end of the first bone unit 10 toward the second connection unit 21 of the second bone unit 20, so that the first connection unit 11 is assembled in the corresponding recessed second connection unit 21 of the second bone unit 20. The second cavity unit 22 has a third connection port 24 at the other end of the second connection port 23.
[0021] A liquid storage unit 30, one end of which is connected to the third connection port 24, is used to receive and store the liquid injected during puncture by the bone needle 200;
[0022] A locking fastener 40 is disposed at the first connecting unit 11 of the first skeleton unit 10 and the second connecting unit 21 of the assembled second skeleton unit 20. The locking fastener 40 is locked through the second skeleton unit 20, thereby locking and fixing the locking fastener 40 to the first skeleton unit 10; and
[0023] A skin unit 50 covers the outer periphery of the first bone unit 10 and the second bone unit 20;
[0024] The first connection port 13 is connected to the second connection port 23, so that the first cavity unit 12 is connected to the second cavity unit 22;
[0025] When the bone needle 200 is punctured into the first cavity unit 12 for injection, the liquid injected by the bone needle 200 will flow from the first cavity unit 12 through the second cavity unit 22 to the liquid storage unit 30.
[0026] First, please refer to Figures 1 to 4. The bone needle puncture training device 100 of this invention is constructed by assembling the first connecting unit 11 of the first bone unit 10 onto the second connecting unit 21 of the second bone unit 20. The first guiding unit 111 of the first connecting unit 11 is guided by the second guiding unit 211 of the second connecting unit 21, thereby allowing the first connecting unit 11 to abut against the second connecting unit 21. In this way, the first connecting port 13 abuts against and connects to the second connecting port 23, allowing the first cavity unit 12 to connect to the liquid storage unit 30 connected to the third connecting port 24 via the connected second cavity unit 22. The locking fastener 40 locks and fixes the first bone unit 10 to the second bone unit 20. Then, the skin unit 50 covers the first bone unit 10 and the second bone unit 20.
[0027] Furthermore, when practicing, please refer to Figure 4. The skin unit 50 covers the first bone unit 10. Therefore, the user can touch the first feature unit 14 protruding from the first bone unit 10 along the skin unit 50. The first feature unit 14 is used to allow the user to identify the intended insertion point of the bone needle 200. After the user applies the bone needle 200 to the insertion point, if the bone needle 200 punctures the first cavity unit 12 of the first bone unit 10, liquid will flow from the bone needle 200. When the liquid is injected into the first cavity unit 12, it flows from the first cavity unit 12 along the first connection port 13 through the second cavity unit 22 connected by the second connection port 23, and then stores the liquid in the reservoir unit 30 connected by the third connection port 24 of the second cavity unit 22. After the first bone unit 10 is used up, it can be separated from the second bone unit 20 and replaced with another new first bone unit 10, so that relevant personnel can use it repeatedly to achieve the training effect.
[0028] Please refer to Figures 1 to 4. The bone needle puncture training device 100 further includes a tendon unit 60 on the other side of the first bone unit 10 opposite to the first feature unit 14. The tendon unit 60 is electrically connected to an alarm processing unit 70. When the bone needle 200 contacts the tendon unit 60, the alarm processing unit 70 receives and processes the signal returned by the tendon unit 60 and generates an alarm signal.
[0029] In summary, the bone needle puncture training device 100 of this invention mainly involves assembling the first connecting unit 11 of the first bone unit 10 onto the second connecting unit 21 of the second bone unit 20, and locking the first bone unit 10 to the second bone unit 20 with the locking fastener 40. The first cavity unit 12 is connected to the second connecting port 23 via the first connecting port 13, and the first cavity unit 12 can connect to the second cavity unit 22 and the fluid storage unit 30. The skin unit 50 covers the assembled first bone unit 10 and second bone unit 20, allowing the user to practice... The insertion position of the bone needle 200 is determined through the first feature unit 14. After the bone needle 200 is punctured, an infusion is injected into the first cavity unit 12. After the infusion enters the first cavity unit 12, it will flow through the second cavity unit 22 to the reservoir unit 30. The first bone unit 10 can be replaced as needed to provide other users with the opportunity to practice bone needle puncture. Thus, the bone needle puncture training device 100 of this invention not only provides realistic teaching training, but also makes it more convenient to use as the first bone unit 10 can be replaced after training.
