[0002] An arterial pressure monitoring device is a medical device used to monitor arterial pressure in real time. It has important application value in clinical medicine, especially in critical patient monitoring, surgical procedures, and cardiovascular disease management. Arterial pressure monitoring devices primarily work by implanting a cannula or pressure sensor into the artery and connecting it to a pressure measurement system to directly measure pressure changes within the artery. Depending on the implantation method and monitoring principle, they can be divided into two categories: invasive arterial pressure monitoring devices and non-invasive arterial pressure monitoring devices. Invasive arterial pressure monitoring devices directly measure arterial pressure by implanting a cannula into the artery and connecting it to a pressure measurement system. Invasive arterial pressure monitoring devices generally consist of an arterial cannula, a pressure measurement system, a flushing system, and an electronic monitor. This monitoring method is highly accurate, but is somewhat invasive and requires strict aseptic operation and postoperative care.

[0003] The above-mentioned existing technical solutions have the following defects: multiple parts of the existing blood pressure monitoring structure need to be connected using a spiral structure. When drawing blood during the monitoring process, the spiral structure is prone to blood accumulation, causing thrombosis or unnecessary infection. Therefore, we propose an integrated arterial pressure monitoring device to solve the above-mentioned problems. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] See also Figure 1The present invention provides an embodiment of an integrated arterial pressure monitoring device, comprising an arterial pressure monitoring device body 1 and a blood pressure monitor 2. The arterial pressure monitoring device body 1 comprises an arterial needle interface 3, a pressure tube 4, a first three-way valve 5, a second three-way valve 6, a third three-way valve 8, a blood pressure sensor 9, a first blood pressure monitor connection line 10, a second blood pressure monitor connection line 11, a flow rate regulating valve 12, a saline bag connector 13, and a drip tube 14. One end of the arterial pressure monitoring device body 1 is provided with an arterial needle interface 3, the upper end of the arterial needle interface 3 is connected to the pressure tube 4, the end of the pressure tube 4 close to the arterial needle interface 3 is connected to the first three-way valve 5 and the second three-way valve 6, the first three-way valve 5 is located on one side of the second three-way valve 6, a blood pressure sensor 9 is provided in the middle position of the pressure tube 4, the pressure tube 4 is respectively connected to the arterial needle interface 3, the first three-way valve 5, and the second three-way valve 6, the pressure tube 4 is respectively connected to the third three-way valve 8 and the blood pressure sensor 9, and the pressure tube 4 is respectively connected to the saline bag connector 13 and the drip tube 14.

[0019] The pressure tube 4 is integrally connected to the arterial needle interface 3, the first three-way valve 5 and the second three-way valve 6 respectively. The pressure tube 4 is integrally connected to the third three-way valve 8 and the blood pressure sensor 9 respectively. The pressure tube 4 is integrally connected to the saline bag connector 13 and the drip tube 14 respectively. The integrated structure can effectively improve the sealing effect of the arterial pressure monitoring device; one end of the first three-way valve 5 is sealedly connected to the suction needle 7. Before drawing blood, the first three-way valve 5 is rotated to generate negative pressure through the suction needle 7 for suction, and the mixed part of blood and intravenous saline is extracted, so that the syringe can draw pure blood for analysis. The design of the suction needle 7 can achieve the extraction of a certain amount of blood to ensure that the mixture of saline and blood is extracted. Then the first three-way valve 5 is rotated to connect the arterial needle interface 3 and the second three-way valve 6. One end of the second three-way valve 6 is connected to the syringe for blood drawing. The drawn blood can be subjected to blood gas analysis to analyze various required indicators such as blood potassium, sodium, calcium and pH. After blood collection, the blood drawn by the suction needle 7 is injected into the human blood vessels to prevent anemia. The connection between the aspiration needle 7 and the first three-way valve 5 adopts a conical structure, which can make the blood flow out in a spiral, avoiding the formation of blood clots on the tube wall. The layout between the aspiration needle 7, the first three-way valve 5, the second three-way valve 6 and the arterial needle interface can prevent blood from flowing back into the aspiration needle 7 during flushing, causing incomplete flushing and easily leading to blood clots. Figure 1 One side of the blood pressure sensor 9 is connected to the third three-way valve 8, and the other end of the arterial pressure monitoring device body 1 is provided with a saline bag connector 13, one side of the saline bag connector 13 is connected to a drip tube 14, and one side of the drip tube 14 is provided with a flow rate regulating valve 12, and the flow rate regulating valve 12 is located outside the pressure tube 4.

[0020] See also Figure 1The upper end of the blood pressure sensor 9 is connected to the first blood pressure monitor connection line 10, and one side of the blood pressure monitor 2 is connected to the second blood pressure monitor connection line 11. The second blood pressure monitor connection line 11 is connected to the first blood pressure monitor connection line 10 through a connector. One end of the first three-way valve 5 is sealed with a suction needle tube 7. The external sealing sleeve of the suction needle tube 7 and the connecting end of the first three-way valve 5 and the suction needle tube 7 is covered with a sealing silicone sleeve 15. As it is pulled, the sealing silicone sleeve 15 can be folded and unfolded without affecting the observation of the blood in the syringe tube, and can also achieve a better sterile effect.

[0021] Working principle: when in use, after the dropper 14 is injected into the saline bag, the arterial needle is connected to the arterial needle interface 3, and the air inside the saline is discharged after the saline enters the pressure tube 4. After the arterial needle is injected into the artery, the blood in the artery flows into the pressure tube 4 due to the pressure. One end of the first three-way valve 5 is sealed and connected to the suction needle 7. Before drawing blood, the first three-way valve 5 is rotated to generate negative pressure through the suction needle 7 for suction, and the mixed part of the blood and the intravenous saline is extracted, so that the syringe can draw pure blood for analysis. The design of the suction needle 7 can achieve the extraction of a certain amount of blood to ensure that the mixture of saline and blood is extracted. Then the first three-way valve 5 is rotated to connect the arterial needle interface 3 and the second three-way valve 6. One end of the second three-way valve 6 is connected to the syringe for blood drawing. The drawn blood can be subjected to blood gas analysis to analyze the various required indicators such as potassium, sodium, calcium and pH of the blood. After blood collection, the blood drawn by the suction needle 7 is injected into the human blood vessels to prevent anemia. The second and third-way valves 6 connect the arterial needle interface 3 and the blood pressure sensor 9. The blood pressure sensor 9 converts the received blood pressure signal into an electrical signal and transmits it to the blood pressure monitor 2 via the first and second blood pressure monitor connection lines 10 and 11. The blood pressure monitor 2 then uses a specific calculation method to obtain a dynamic waveform of blood pressure changes in real time within the blood vessels. By further processing these signals, specific values such as systolic pressure, diastolic pressure, and mean arterial pressure can be obtained and displayed. One end of the third three-way valve 8 is an atmospheric pressure port that can be controlled to be connected or disconnected to atmospheric pressure. The saline bag connector 13 can be connected to the airbag and the saline bag. When pressed hard, the pipeline can be quickly flushed. Flushing the pressure tube 4 with heparinized saline or air can effectively prevent blood from clotting in the pipeline and keep the pipeline unobstructed. After each arterial blood is drawn through the pressure tube, it is immediately quickly flushed with heparinized saline to prevent clotting and thereby reduce the risk of thrombosis.

[0022] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
