Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to an intelligent multi-functional invasive arterial catheter connection device. Background Art

[0002] An invasive arterial catheter connection device is a medical device for connecting an arterial catheter. Its main functions are to real-time monitor indicators such as the patient's invasive arterial pressure, heart rate, and blood oxygen saturation, and at the same time provide a channel for arterial blood gas analysis or autologous blood collection. However, repeatedly opening the channel to collect arterial blood greatly increases the probability of infection, and manual supervision is required during blood collection, and the functions of controlling the flow rate and volume of autologous blood cannot be achieved, which increases the workload of medical staff. At the same time, it is difficult for the arterial catheter connection device to cooperate with a fixed rack such as a hospital bed or an infusion stand for fixed use during operation, resulting in the problem that it is prone to tipping and damage after accidental contact, affecting normal use. Moreover, after the arterial connection device is displaced, the catheter connection is likely to loosen and fall off, resulting in a large amount of arterial blood loss, which will endanger the patient's life. Especially for children or neonates, such harm is fatal. Therefore, it is necessary to improve the existing arterial connection device. Summary of the Invention

The blood collection bag 40 is placed in the storage box 39. The peristaltic pump 41 and the small blood flowmeter 42 are respectively fixedly connected to the top surface of the support base 38.

[0027] As Figure 3 shown, a back plate 12 is fixedly installed on the left side of the rear end wall of the intelligent monitor body 1. A set of vertically symmetric guide holes 13 are provided on the side wall of the back plate 12. The guide holes 13 are used to cooperate with the guide rod 22 to guide the movement of the left clamping plate 20. A first rotation hole 14 is further provided between the guide holes 13 on the side wall of the back plate 12. The first rotation hole 14 is used to cooperate with the first rotating rod 17 to realize the rotation operation. A ring groove 15 is provided on the inner wall of the first rotation hole 14. The ring groove 15 is used to cooperate with the limit ring 18 to realize the rotation operation and can limit the first rotating rod 17 to rotate within the first rotation hole 14;

[0028] As Figure 3As shown in the figure, a first rotating rod 17 is fixedly installed on the right side wall of the first knob 16, and the first rotating rod 17 is movably installed in the first rotating hole 14.

The right clamping plate 21 is fixedly installed on the rear end wall of the intelligent monitor body 1, and arc-shaped clamping grooves 24 are respectively opened on the opposite side walls of the right clamping plate 21 and the left clamping plate 20. A number of anti-slip arc-shaped strips 25 are fixedly installed on the inner wall of the arc-shaped clamping groove 24 in a vertical array. After placing the vertical rod 8 between the left clamping plate 20 and the right clamping plate 21, rotate the first knob 16 to drive the first rotating rod 17 to rotate the first rotating rod 17 at a fixed position through the limiting ring 18, so that the threaded rod 23 pushes the left clamping plate 20 in the right direction along the first threaded hole 19 and approaches the right clamping plate 21 fixed on the rear end wall of the intelligent monitor body 1. The left clamping plate 20 and the right clamping plate 21 will clamp and fix the vertical rod 8 through the arc-shaped clamping grooves 24 opened on the opposite side walls, and further cooperate with the use of the anti-slip arc-shaped strips 25 to ensure the clamping friction force with the vertical rod 8, prevent the problem of the intelligent monitor body 1 sliding down after being installed on the vertical rod 8, and thus achieve the purpose of facilitating the installation and fixation of the whole device on a fixed frame such as a hospital bed or an infusion stand for use;

[0029] As Figure 2 shown, an arterial catheter interface 4, an invasive arterial blood pressure monitor interface 5, a blood gas analyzer interface 6, and a blood sampling catheter interface 7 are respectively fixedly installed on the right side wall of the intelligent monitor body 1 from top to bottom. The arterial catheter interface 4 is connected to the arterial catheter at the patient end. The invasive arterial blood pressure monitor interface 5 is connected to the monitor end with an arterial transducer for monitoring vital signs such as invasive blood pressure, heart rate, blood oxygen saturation, body temperature, etc. The blood gas analyzer interface 6 is connected to the blood gas analyzer end and can monitor indicators such as electrolytes, acid-base, hemoglobin, etc. The blood sampling catheter interface 7 is connected to the autologous blood collection mechanism to automatically collect the patient's autologous blood;

[0030] As Figure 4 shown, a frame 26 is also fixedly installed on the right side wall of the intelligent monitor body 1, and sliding openings 27 are respectively opened on the top surface and the bottom surface of the frame 26 for sliding operation in cooperation with the sliding strips 34. A group of front and rear symmetric fixing blocks 28 are fixedly installed on the top surface of the frame 26, and a second rotating hole 29 is opened on the side wall of the fixing block 28 for rotating operation in cooperation with the second rotating rod 31;

[0031] As Figure 5 shown, second rotating rods 31 are fixedly installed at the front and rear ends of the bidirectional screw rod 30 respectively, and the second rotating rods 31 are movably installed in the second rotating holes 29. A second knob 32 is also fixedly installed on the front end wall of the front second rotating rod 31. A set of symmetrical clamping strips 33 are provided, and sliding strips 34 are fixedly installed at the top and bottom ends of the clamping strips 33 respectively. The sliding strips 34 are movably installed in the sliding openings 27, and a connecting block 35 is also fixedly installed on the top surface of the sliding strip 34. A second screw hole 36 is provided on the side wall of the connecting block 35, and the connecting block 35 is threadedly connected to the bidirectional screw rod 30 through the second screw hole 36. Arc-shaped clamping openings 37 corresponding to the arterial catheter interface 4, the invasive arterial blood pressure monitor interface 5, the blood gas analyzer interface 6, and the blood sampling catheter interface 7 are respectively provided on the opposite surface walls of the symmetrical clamping strips 33. After the catheter or the instrument connection wire is connected to the corresponding position on the right side of the intelligent monitor body 1, rotate the second knob 32 to drive the bidirectional screw rod 30 to rotate through the second rotating rod 31, so that the symmetrical connecting blocks 35 respectively make relative movement operations through the second screw holes 36, and the connecting blocks 35 drive the sliding strips 34 to slide in the sliding openings 27, and the sliding strips 34 drive the clamping strips 33 to move in the frame body 26, and the symmetrical clamping strips 33 make relative movement operations until the corresponding wires or connection wires are clamped and fixed between the clamping strips 33 through the arc-shaped clamping openings 37 provided on the corresponding clamping strips 33, so as to play a role in preventing the catheter or the connection wire from falling off, avoiding the problem that the catheter or the connection wire falls off from the intelligent monitor body 1 due to factors such as external force pulling, so as to ensure the normal use of the device;

[0032] As Figure 6 shown, a support base 38 is fixedly installed on the bottom surface of the intelligent monitor body 1. The support base 38 is used for fixedly supporting the peristaltic pump 41 and the blood small flowmeter 42, and a storage box 39 is fixedly installed on the bottom surface of the support base 38. The storage box 39 is used for placing the blood collection bag 40;

[0033] As Figure 6As shown, the blood collection bag 40 is movably installed in the storage box 39. The peristaltic pump 41 is fixedly installed on the inner bottom surface of the notch of the support base 38. And on the top surface of the support base 38 and to the left of the peristaltic pump 41, a small blood flow meter 42 is also fixedly installed. A blood extraction delivery catheter 43 is fixedly installed between the blood extraction catheter interface 7 and the input end of the blood collection bag 40. And the blood extraction delivery catheter 43 passes through the peristaltic pump 41 and the small blood flow meter 42 in sequence. The blood extraction catheter interface 7 on the intelligent monitor body 1 is communicated with the arterial catheter interface 4. After the arterial catheter interface 4 is adjacent to the patient's artery through the arterial catheter, when the peristaltic pump 41 is started, the patient's blood can be extracted through the blood extraction delivery catheter 43. When the blood is transported to the blood collection bag 40 through the blood extraction delivery catheter 43, it will pass through the small blood flow meter 42. The small blood flow meter 42 monitors the flow rate of the transported blood. Until the flow rate of the transported blood reaches the preset value, the extraction of the patient's blood is stopped, which can ensure that the volume of the patient's blood extracted in the blood collection bag 40 meets the collection volume requirement, so as to achieve the purpose of automatically and accurately collecting the patient's autologous blood.

[0034] The specific usage principle and operation of the installation mechanism 9, the anti-detachment mechanism 10, and the autologous blood collection mechanism 11 in cooperation with the intelligent monitor body 1 are as follows:

[0035] Before using this device, install the device on the vertical rod 8 of a fixed rack such as a hospital bed or an infusion stand through the installation mechanism 9. During installation, place the vertical rod 8 between the left clamping plate 20 and the right clamping plate 21. Rotate the first knob 16 on the left side wall of the back plate 12. The first knob 16 drives the first rotating rod 17 to rotate in the first rotating hole 14. The first rotating rod 17 drives the limiting ring 18 to rotate in the ring groove 15. Under the cooperative limiting action of the limiting ring 18 and the ring groove 15, the first rotating rod 17 will be positioned and rotated in the first rotating hole 14, so that the threaded rod 23 pushes the left clamping plate 20 to the right along the first threaded hole 19 opened on the end wall of the first rotating rod 17. The guide rod 22 on the left side wall of the left clamping plate 20 moves along the guide hole 13. The left clamping plate 20 will approach the right clamping plate 21 fixed on the rear end wall of the intelligent monitor body 1 until the vertical rod 8 is anti-slip clamped and fixed by the arc-shaped clamping grooves 24 opened on the opposite side walls of the left clamping plate 20 and the right clamping plate 21 and several anti-slip arc-shaped strips 25 vertically arranged in the arc-shaped clamping grooves 24. In this way, the device can be installed and fixed on a fixed rack such as a hospital bed or an infusion stand for use;

[0036] On the right side of the intelligent monitor body 1, there are an arterial catheter interface 4, an invasive arterial blood pressure monitor interface 5, a blood gas analyzer interface 6, and a blood sampling catheter interface 7. The arterial catheter interface 4 is connected to the arterial catheter at the patient end to use the intelligent monitor body 1 to monitor the patient in real time. After the monitor end with an arterial transducer is connected to the invasive arterial blood pressure monitor interface 5 through a connecting wire, the intelligent monitor body 1 can be used to monitor vital signs such as the patient's invasive blood pressure, heart rate, blood oxygen saturation, body temperature, etc. When the blood gas analyzer end is connected to the blood gas analyzer interface 6 through a connecting wire, the intelligent monitor body 1 can monitor indicators such as the patient's electrolytes, acid-base balance, hemoglobin, etc. When connected to the blood sampling catheter interface 7 through the blood sampling delivery catheter 43, the intelligent monitor body 1 can automatically collect autologous blood through the autologous blood collection mechanism 11. When the required connecting wire or catheter is connected to the corresponding interface on the right side of the intelligent monitor body 1, rotate the second knob 32 to drive the second rotating rod 31 to rotate in the second rotating hole 29 opened on the side wall of the fixed block 28. The second rotating rod 31 will drive the bidirectional screw 30 to rotate, causing the symmetrical connecting blocks 35 to move relatively along the bidirectional screw 30 through the second screw holes 36 opened on the side walls. When moving, the sliding strips 34 at the top and bottom of the clamping strip 33 will slide in the sliding openings 27 opened on the top and bottom surfaces of the frame body 26, and the symmetrical clamping strips 33 will perform a relative movement operation until the catheter or connecting wire is clamped and fixed through the arc-shaped clamping openings 37 opened on the opposite side walls corresponding to the arterial catheter interface 4, the invasive arterial blood pressure monitor interface 5, the blood gas analyzer interface 6, and the blood sampling catheter interface 7, which can play a role in preventing the catheter or connecting wire from falling off, avoiding the problem that the catheter or connecting wire falls off the intelligent monitor body due to factors such as external force pulling, to ensure the normal use of the device;

[0037] When it is necessary to collect the patient's blood, the intelligent monitor body 1 controls the autologous blood collection mechanism 11. The patient's blood will enter the intelligent monitor body 1 through the arterial catheter interface 4 and then flow out to the blood sampling delivery catheter 43 through the blood sampling catheter interface 7. At this time, the peristaltic pump 41 installed on the inner bottom surface of the support base 38 will transport the blood in the blood sampling delivery catheter 43. The peristaltic pump 41 can control the blood delivery flow rate. The blood during the transportation process will enter the blood collection bag 40 placed in the storage box 39 after passing through the blood small flowmeter 42. The blood collection bag 40 is used to collect the blood. At the same time, the blood small flowmeter 42 will monitor the flow rate of the transported blood. When the flow rate reaches the volume required to be collected by the blood collection bag 40, the peristaltic pump 41 will stop transporting the blood, so as to achieve the purpose of automatically and accurately collecting the patient's autologous blood;

[0038] Furthermore, the device will integrate functions such as invasive arterial blood pressure monitoring, blood gas analysis, and monitoring of autologous blood collection. It can also monitor the pressure changes within the arterial catheter system. If the pressure is too high or too low beyond the set threshold, the device can issue an alarm in a timely manner. Through the provided arterial catheter interface 4, invasive arterial blood pressure monitor interface 5, blood gas analyzer interface 6, and blood sampling catheter interface 7, where the arterial catheter interface 4 is the patient end of the arterial catheter, and the other three are functional ends, appropriate ports can be selected according to needs. One is connected to the arterial catheter at the patient end, and the other two are connected to the monitor end with an arterial transducer, used to monitor vital signs such as invasive blood pressure, heart rate, blood oxygen saturation, and body temperature. The third is connected to the blood gas analyzer end, which can monitor indicators such as electrolytes, acid-base balance, and hemoglobin. The fourth can be connected to an autologous blood collection device, where the volume of autologous blood to be collected can be set. After reaching the collection volume, the autologous blood collection will automatically stop, and the speed and volume of autologous blood collection can be displayed through the display screen 2. The integrated design can instantaneously monitor indicators such as hemoglobin and hematocrit before and after autologous blood collection to ensure the safety of the patient. Through the intelligent monitor body 1, data such as invasive blood pressure, heart rate, and blood gas results can be displayed synchronously with the monitor and blood gas analyzer, and warnings can be given for abnormal values to achieve intelligent supervision of the arterial catheter connection system.

Although the present invention has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present invention, and components therein can be replaced with equivalents, or some of the technical features can be equivalently replaced.
