Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a simple coronary contrast agent push injection training device. Background Art

[0002] Cardiovascular physicians must learn how to inject contrast agents in order to master coronary diagnosis and treatment techniques. Practicing to maintain a certain pressure of contrast agent injection is an essential element for successful coronary angiography. Young cardiovascular physicians find it difficult to master the strength, speed, pressure and other key points of contrast agent injection when they first learn coronary angiography techniques.

[0003] If the contrast agent push pressure is not well controlled, such as: when the push pressure is small, the coronary contrast agent is not fully filled, resulting in waste of contrast agent and increasing the amount of contrast, which can easily cause a burden on the patient's kidneys and cause contrast agent-related complications; when the push pressure is high, it can easily cause the connecting pipeline to detach from the coronary sinus ostium, increasing the operation time, and can also easily cause tearing of the coronary sinus ostium, inducing the risk of complications such as cardiac arrest, coronary artery dissection, and malignant arrhythmia.

[0004] Uniform and steady injection of contrast agent at a certain pressure is also a key determinant of the clarity of the angiography image, and the clarity of the image directly affects the interpretation of the results of coronary angiography (such as: causing errors in the assessment of the degree of coronary artery stenosis, air embolism, coronary artery dissection, unclear exposure of branch vessels, etc.).

[0005] In summary, there is a need for a simple contrast agent injection training device that can help physicians who are new to coronary intervention diagnosis and treatment techniques to quickly master the injection of contrast agents, thereby accelerating the learning curve of coronary intervention diagnosis and treatment techniques, improving the quality of angiographic images, and increasing the speed of mastering proficiency.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] The embodiment of the utility model provides a simple coronary contrast agent push-in training device, comprising a triple three-way tube 1 and a pusher 2, and also comprising a storage container 3 for accommodating contrast agent, a connecting pipeline 4 and a placement rack 5 for supporting the storage container 3, wherein the storage container 3 is a transparent glass container, and a scale showing the volume of the contrast agent is arranged on the transparent glass container, the pusher 2 is a finger ring pusher, and the placement rack 5 comprises a base 51 and a placement plate 52, wherein the base 51 is horizontally arranged on a desktop, and the placement plate 52 is horizontally arranged above the base 51, and the upper surface area of ​​the placement plate 52 is used to place the storage container 3 filled with contrast agent, and a plurality of support components 53 arranged equidistantly are arranged between the base 51 and the placement plate 52;

[0028] Before practicing with the coronary angiography push injection training device, the trainee first places the storage container 3 filled with about one third of contrast agent on the placement rack 5, and then inserts one end of the connecting pipe 4 from the bottle mouth end of the storage container 3 into the interior of the storage container 3, and then connects the other end of the connecting pipe 4 to the front end of the triple three-way pipe 1, and then the trainee connects the injection end of the pusher 2 to the end of the triple three-way pipe 1, and the whole device is assembled;

[0029] When practicing the contrast agent injection technique of angiography, the practitioner can sit on a chair and operate in a sitting position, and place the placement rack 5 on the practice table so that the scale on the storage container 3 is in a corresponding state with the practitioner's line of sight, so as to facilitate observation;

[0030] During the practice, the practitioner can hold the syringe 2 to withdraw. At this moment, the contrast agent in the storage container 3 will flow from one end of the connecting pipe 4 inserted into the bottle mouth into the other end thereof, and then flow into the triple three-way tube 1, and finally flow into the syringe 2 from the end of the triple three-way tube 1. At this time, the practitioner needs to inject the syringe 2 with the contrast agent so that the contrast agent in the syringe 2 will be injected into the triple three-way tube 1 from the injection end of the syringe 2 again. When the contrast agent is slowly injected by the syringe 2, the contrast agent in the triple three-way tube 1 will gradually flow into the connecting pipe 4, and be ejected from the head end of the connecting pipe 4 back into the storage container 3. During the injection process, the practitioner can observe the injection of the contrast agent from the head end of the connecting pipe 4 to the inner wall of the storage container 3. At this time, the practitioner needs to maintain a certain pressure and injection speed, and observe while injecting, so that the injection of the contrast agent at the head end of the connecting pipe 4 is kept on different scales in the storage container 3.

[0031] Through repeated attempts by trainees to push injections, they can feel the injection pressure and speed, and keep the contrast agent spray at the head end of the connecting pipeline 4 at different scales in the storage container 3 to simulate different arterial pressures in the patient's body. Through injection exercises using a simple coronary contrast agent push injection training device, trainees can become familiar with the push injection of contrast agents, and maintain a certain push pressure and speed feel during the push injection process, which is convenient for trainees to quickly get started in clinical coronary intervention diagnosis and treatment for patients and achieve satisfactory contrast agent push injection effects.

[0032] In a further embodiment, referring to Figure 2 and Figure 3 As shown, the support assembly 53 includes a support rod 531 and a telescopic rod 532;

[0033] The support rod 531 is vertically arranged on the base 51, the interior of the support rod 531 is arranged in a cavity shape and an opening is arranged at its upper end, the bottom of the support rod 531 is fixedly connected to the upper surface of the base 51, the telescopic rod 532 is vertically inserted in the cavity of the support rod 531, the top of the telescopic rod 532 extends toward the outside of the top of the support rod 531, and is fixedly connected to the bottom of the placing plate 52, and the telescopic rod 532 can be raised and lowered in the support rod 531;

[0034] When the practitioner places the storage container 3 containing the contrast agent on the placement rack 5 and then sits on the chair to start practicing, since different practitioners have different heights, the practitioner's line of sight cannot be kept in a corresponding state with the scale on the storage container 3. Therefore, the practitioner can adjust the height of the placement rack 5. First, the practitioner presses the base 51 in the placement rack 5 with one hand so that it is pressed on the practice table, and then holds the bottom of the placing plate 52 with the other hand and applies force upward to move the placing plate 52 upward. At this time, the telescopic rod 532 at the bottom of the placing plate 52 will also move upward in the support rod 531 on the base 51. When the placing plate 52 rises to the specified height, the telescopic rod 532 will stop moving in the support rod 531, and the scale of the storage container 3 on the placing plate 52 will be in a corresponding state with the practitioner's line of sight, so that the entire device can be suitable for practitioners of different heights, thereby improving the applicability of the entire device;

[0035] Furthermore, by providing the support rod 531 and the telescopic rod 532 , support is provided for the placing plate 52 when it is located above the base 51 , so that the base 51 and the placing plate 52 are more stable.

[0036] In a further embodiment, referring to Figure 4 As shown, a plurality of slots 533 arranged linearly up and down are provided on the inner wall of each support rod 531, and a plurality of flexible card blocks 534 arranged equidistantly up and down are fixedly provided on the outer wall of the telescopic rod 532 in each support rod 531, and correspond one by one to the plurality of slots 533 provided on the inner wall of the corresponding support rod 531;

[0037] When the practitioner adjusts the height of the corresponding placement rack 5, each telescopic rod 532 will be raised and lowered in the cavity of the corresponding support rod 531. During the lifting and lowering process of the telescopic rod 532, the flexible block 534 provided on the telescopic rod 532 will also move together. When the telescopic rod 532 is lifted and lowered to the specified position, the flexible block 534 on the telescopic rod 532 will be embedded in the groove 533 provided on the inner wall of the corresponding support rod 531, thereby restricting the telescopic rod 532 on the support rod 531, so that the telescopic rod 532 will not be lifted and lowered in the support rod 531 without external force. By providing multiple flexible blocks 534 and grooves 533, the restriction strength of the telescopic rod 532 can be strengthened.

[0038] In a further embodiment, referring to Figure 3 As shown, a plurality of stoppers 511 arranged in a ring are fixedly disposed at the edge of the upper surface of the placing plate 52, and form a placement area;

[0039] After the storage container 3 containing contrast agent is placed on the supporting plate 52, the storage container 3 can be placed in the placement area formed by the multiple blocks 511 through the cooperation of the multiple blocks 511 set on the upper surface of the supporting plate 52, so as to prevent the storage container 3 from sliding off the supporting plate 52 when the training table is hit.

[0040] In a further embodiment, referring to Figure 5 and Figure 6 As shown, a seal 6 is provided outside the connection between the triple tee pipe 1 and the connecting pipeline 4, and the seal 6 includes an upper sealing cover 61 and a lower sealing cover 62. The upper sealing cover 61 can cover the upper part of the connection between the triple tee pipe 1 and the connecting pipeline 4, and a plurality of magnetic blocks 64 are fixedly provided on both sides of the upper sealing cover 61 close to the lower sealing cover 61, and the lower sealing cover 62 can cover the lower part of the connection between the triple tee pipe 1 and the connecting pipeline 4, and a plurality of jacks 63 are provided on both sides of the lower sealing cover 62 close to the upper sealing cover 61, and a metal ring that can be magnetically adsorbed with the magnetic block 64 is fixedly provided in each jack 63;

[0041] Reference Figure 7 As shown, semicircular water-absorbing cotton 65 is provided on both sides of the inner wall of the upper sealing cover 61 and the lower sealing cover 62, and the back of the water-absorbing cotton 65 is adhered to the inner wall of the corresponding upper sealing cover 61 and the lower sealing cover 62;

[0042] After the practitioner connects the connecting pipeline 4 and the three-way pipe 1 together, the upper sealing cover 61 and the lower sealing cover 62 are respectively covered on the outer wall of the connection between the connecting pipeline 4 and the three-way pipe 1. When the upper sealing cover 61 and the lower sealing cover 62 are attached to each other, a sealed cavity is formed, so that the connection between the connecting pipeline 4 and the three-way pipe 1 is in the sealed cavity. When the upper sealing cover 61 and the lower sealing cover 62 are installed, once there is leakage of contrast agent in the sealed cavity formed by the upper sealing cover 61 and the lower sealing cover 62, the contrast agent in the sealed cavity formed by the upper sealing cover 61 and the lower sealing cover 62 can be absorbed by the absorbent cotton 65, so as to further improve the sealing effect between the upper sealing cover 61 and the lower sealing cover 62.

[0043] Secondly, when the upper sealing cover 61 and the lower sealing cover 62 are attached to the connection between the connecting pipeline 4 and the triple three-way pipe 1, the multiple magnetic blocks 64 arranged on the upper sealing cover 61 will be embedded in the corresponding plug holes 63 of the lower sealing cover 62, and the end of the magnetic block 64 inserted into the plug hole 63 will be magnetically connected with the metal ring fixed in the plug hole 63, so that the upper sealing cover 61 and the lower sealing cover 62 can be clamped at the connection between the connecting pipeline 4 and the triple three-way pipe 1, making the assembly and disassembly of the upper sealing cover 61 and the lower sealing cover 62 more convenient;

[0044] The upper sealing cover 61 and the lower sealing cover 62 are both made of lightweight medical resin material, and their weight will not affect the magnetic attraction strength between the magnetic block 64 and the corresponding metal ring in the socket 63, thereby causing the problem of separation between the magnetic block 64 and the socket 63.

[0045] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
