[0002] Currently, cardiac interventional surgery is the gold standard for diagnosing coronary heart disease. It requires the use of contrast agents to visualize the coronary arteries. The amount of contrast agent required for each patient is different, and the amount can only be determined during the operation. During the operation, the contrast agent is often insufficient. If it is not replaced in time when it is used up and the operation is continued, there is a risk of air entering the body and causing air embolism. Generally, when it is found that the contrast agent is insufficient, the nurse needs to bring the contrast agent for replacement. Due to the tight time and rush of personnel during the operation, when replacing the contrast agent, when the infusion connector at the end of the contrast agent bottle is pulled out in a hurry, a lot of contrast agent will be spilled everywhere. In order to solve the above situation, this solution was created. Utility Model Content

[0019] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description.

[0020] like Figures 1-4 As shown, this embodiment provides an automatic contrast agent replenishing device, including a bracket 1, a mounting seat 2, a concentration bottle 3, a detection component 4, two automatic bottle opening components 5, an alarm prompt device and a control panel.

[0021] An installation frame 11 is provided above the bracket 1, and the mounting seat 2 is located on the installation frame 11. A receiving seat 12 is provided in the middle of the bracket 1, and a conical hole is provided in the middle of the receiving seat 12. The concentrating bottle 3 is clamped in the conical hole, and upwardly extending extension plates 121 are formed on both sides of the receiving seat 12.

[0022] The mounting seat 2 is provided with two mounting openings. The mounting holes are used to insert the bottle mouth or bottle body of the contrast agent bottle and are set according to the shape of the contrast agent bottle. A nylon ring 22 is provided on the circumference of the mounting opening. The vertical cross-section of the inner ring of the nylon ring 22 is an inclined surface. The nylon ring 22 has a certain degree of deformation ability, which can tighten the contrast agent bottle more firmly when inserted. The mounting seat 2 has a first chamber 21. The bottom of the first chamber 21 is provided with a clearance groove on both sides. The clearance groove includes a placement portion and a movable portion. The movable portion is located at the lower end of the placement portion. The length of the movable portion is greater than the length of the placement portion and one side passes through the side wall of the mounting seat 2.

[0023] The two automatic bottle opening components 5 are respectively located in the two mounting ports. Specifically, the automatic bottle opening component 5 includes a needle tube 51, a connecting tube 52 and a driving component. The needle tube 51 is located in the mounting seat 2. The driving component is used to drive the needle to penetrate the contrast agent opening. Specifically, the driving component includes a push plate 53, two first moving plates 54, two second moving plates 55 and two driving cylinders 56. The driving cylinders 56 are cylinders. The push plate 53 is located at the bottom of the first chamber 21. A through hole is provided in the middle of the push plate 53. Each of the push plates 53 is provided with a through hole. There is a first movable plate 54 and a second movable plate 55 in the groove. The first movable plate 54 is located in the placement part, and the second movable plate 55 is located in the moving part. The first movable plate 54 and the second movable plate 55 are in contact with each other on a slope. The output end of the driving cylinder 56 is fixedly connected to the side wall of the second movable plate 55. The needle tube 51 is fixedly arranged on the upper surface of the ejecting plate 53. Specifically, the needle tube 51 extends through the through hole. The peripheral surface of the needle tube 51 has a connecting ring, which is located above the through hole and is fixedly connected to the ejecting plate 53. By driving the output end of the cylinder 56 to be ejected, the second movable plate 55 is driven to move inward. Under the action of the inclined surfaces of the second movable plate 55 and the first movable plate 54, the first movable plate 54 can only move upward. The two first movable plates 54 move upward, driving the top plate and the needle tube 51 to move upward, and the needle tube 51 penetrates the bottle mouth of the contrast agent bottle. When the contrast agent bottle stopper is made of rubber mouth material, there is no need to set a leak-proof component around the needle tube 51. If the contrast agent bottle stopper is made of other materials, it is necessary to additionally set a leak-proof component between the needle tube 51 and the bottle mouth of the contrast agent bottle.

[0024] The needle tube 51 and the collection bottle 3 are connected via a connecting tube 52. Specifically, the upper surface of the collection bottle 3 has two liquid inlet holes, each of which is connected to the two connecting tubes 52. The lower surface of the collection bottle 3 has a liquid outlet. The length of the connecting tube 52 can be set to a suitable length, and the height of the receiving seat 12 on the bracket 1 is determined accordingly.

[0025] The detection component 4 is used to detect the liquid level of the concentration bottle 3. Specifically, the detection component 4 includes an infrared receiver 41 and an infrared transmitter 42. The infrared receiver 41 and the infrared transmitter 42 are respectively connected to the inner side of the extension plate 121. The infrared receiver 41 and the infrared transmitter 42 correspond to each other on the left and right. When the liquid level is higher than the detection position of the infrared receiver 41 and the infrared transmitter 42, due to refraction, the infrared receiver 41 cannot receive the signal of the infrared transmitter 42. When the liquid level is lower than the detection position of the infrared receiver 41 and the infrared transmitter 42, the infrared receiver 41 cannot receive the signal of the infrared transmitter 42. When the infrared receiver 41 receives the signal from the infrared transmitter 42, the driving cylinder 56 corresponding to the unopened contrast agent bottle will extend, and the output end of the driving cylinder 56 will extend, causing the second movable plate 55 to move. Due to the inclined matching relationship between the first movable plate 54 and the second movable plate 55, the matching surfaces of the first movable plate 54 and the second movable plate 55 are relatively displaced, causing the first movable plate 54 to move upward. When the two first movable plates 54 move upward, the push plate 53 will also move along with the first movable plate 54, causing the needle tube 51 to penetrate the contrast agent bottle.

[0026] The alarm prompt device includes two displacement sensors, which are used to detect whether the output end of the drive cylinder 56 is extended. There is a warning light on the control panel. When both displacement sensors sense that the output end of the cylinder is extended, it means that both bottles of contrast agent have been opened. At this time, the warning light is on, prompting medical staff to replace the contrast agent bottles in time.

[0027] The above shows and describes the basic principles and main features of the invention and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions only illustrate the principles of the utility model. Without departing from the spirit and scope of the invention, the utility model will have various changes and improvements, and these changes and improvements will fall within the scope of the utility model to be protected.
