Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a peritoneal dialysis device. Background Art

[0002] Peritoneal dialysis uses the peritoneum as a semipermeable membrane. Water and solutes are exchanged between the peritoneal capillaries and the dialysate. Electrolytes and small molecules move from the side with high concentration to the side with low concentration (diffusion), and water molecules move from the side with low osmotic concentration to the side with high osmotic concentration (osmosis). Increasing the concentration of the dialysate can achieve the purpose of removing water from the body. The uremic substances in the blood can be removed from the dialysate through the difference in solute concentration gradient, and the electrolyte and acid-base balance can be maintained, replacing some of the functions of the kidneys. In the related art, a peritoneal dialysis machine is usually used for peritoneal dialysis treatment. During the peritoneal dialysis operation, it is necessary to observe the properties of the dialysate, that is, the clarity of the dialysate, such as color and turbidity. If the dialysate becomes turbid or the color changes from colorless to other colors, it is abnormal, which helps to detect complications such as peritonitis.

[0003] Existing peritoneal dialysis devices usually include a pressure control mechanism, a drainage tube and a peritoneal dialysis catheter; one end of the drainage tube is connected to the pressure control mechanism, and the other end is connected to the peritoneal dialysis catheter so that dialysate is introduced through the peritoneal dialysis catheter, and the drainage tube is sequentially connected to a liquid outlet tube and a collection bag so as to drain the dialysate to the collection bag for detection. The drained dialysate usually needs to be manually observed for clarity, which is time-consuming and labor-intensive. At the same time, it is difficult to accurately identify whether the dialysate has abnormalities due to the influence of environmental and human factors, which can easily delay the treatment opportunity.

[0031] Example 1

[0032] See also Figure 1 and Figure 2The present embodiment provides a peritoneal dialysis device, comprising: a main catheter 1, one end of which is connected to a liquid inlet bag 10, and the other end of which is suitable for being placed in the patient's peritoneal cavity to infuse dialysate; a drainage tube 2, one end of which is connected to the peripheral side of the main catheter 1, and the other end of which is connected to a collection bag 3; a detection component, comprising a detection pot 4 and a first detection member 5; the detection pot 4 is connected and arranged on the pipeline of the drainage tube 2; the first detection member 5 is arranged on the detection pot 4, and is suitable for detecting whether the clarity of the liquid in the detection pot 4 is abnormal; wherein the liquid outlet speed of the liquid outlet end of the detection pot 4 is less than the liquid inlet speed of the liquid inlet end of the detection pot 4; an alarm component, which is arranged on the detection pot 4, is in communication connection with the first detection member 5, and is suitable for issuing an alarm when the first detection member 5 detects that the properties of the liquid in the detection pot 4 are abnormal.

[0033] It should be noted that new dialysate is stored in the liquid inlet bag 10; the liquid inlet bag 10 is connected to the main catheter 1, and the collection bag 3 is connected to the drainage tube 2; the clarity of the dialysate refers to the color transparency or turbidity of the dialysate. If the dialysate becomes turbid or the color changes from colorless to other colors, its clarity is abnormal; the main catheter 1 and the drainage tube 2 are both soft tubes.

[0034] Communication connection refers to the communication between connected devices through signal transmission interaction, including wired connection (such as through wires, network cables, etc.) and wireless connection (such as WiFi, 4G connection, etc.).

[0035] In this embodiment, a drainage tube 2 is connected to the main catheter 1. When dialysis is performed, one end of the main catheter 1 is inserted into the patient's abdominal cavity, and the other end is connected to the fluid inlet bag 10. First, the pipeline between the main catheter 1 and the detection component on the drainage tube 2 can be clamped by an external clamping device 12, such as a clamp, to prevent the collection bag 3 from being connected to the main catheter 1 and causing new dialysate to flow into the collection bag 3. Then, the fluid inlet bag 10 is placed at a position higher than the patient's abdominal cavity. Under the action of gravity, the dialysate in the fluid inlet bag 10 is injected into the patient's abdominal cavity through the main catheter 1. After the dialysate is stored in the abdominal cavity for 3-4 hours, the external clamping device 12 on the drainage tube 2 is released, and then the pipeline between the drainage tube 2 and the fluid inlet bag 10 on the main catheter 1 is clamped by an external clamping device 12, such as a clamp, to prevent the fluid inlet bag 10 from being connected to the drainage tube 2 and affecting the outflow of dialysate in the abdominal cavity. Then, the drainage tube 2 and the collection bag 3 are placed at a position lower than the patient's abdominal cavity. According to the suction principle, the dialysate in the peritoneal cavity flows out of the peritoneal cavity under the action of gravity, and the dialysate flows into the drainage tube 2 through the main catheter 1, and flows into the collection bag 3 for recovery after being detected by the detection component in the drainage tube 2. After being recovered by the collection bag 3, a certain volume of dialysate will be accumulated in the detection pot 4 when the dialysate passes through the detection pot 4, so as to avoid the failure to detect the clarity of the dialysate in time when the dialysate flows through the drainage tube 2, thereby improving the detection accuracy, and facilitating the real-time detection of the clarity of the dialysate in the detection pot 4 by the first detection component 5. When the dialysate is drawn out of the patient's body, if the clarity of the dialysate detected by the first detection component 5 is abnormal, a signal is transmitted to the alarm component, and an alarm signal is issued through the alarm component to prompt the patient or other accompanying personnel, so as to find the abnormality in time, help the patient identify peritonitis as early as possible, so as to seek medical treatment in time, improve the degree of intelligence, save time and effort, avoid errors caused by manual observation, have high detection accuracy, and be convenient and simple.

[0036] Example 2

[0037] As a further improvement to Example 1, Figure 1 As shown, the first detection component 5 is a turbidity meter, which is suitable for detecting the turbidity of the liquid in the detection pot 4.

[0038] In this embodiment, the first detection component 5 adopts a turbidity meter, which detects the turbidity of the dialysate in the detection pot 4 in real time. The turbidity threshold can be preset in the turbidity meter. When the turbidity value of the dialysate detected by the turbidity meter exceeds or is equal to the preset turbidity threshold, the clarity of the dialysate is judged to be abnormal, and a signal is sent to the alarm component to issue an alarm through the alarm component.

[0039] As a convertible embodiment, the first detection member 5 may be an electronic eye, which is suitable for detecting the turbidity and color of the liquid in the detection pot 4. It should be noted that the electronic eye may adopt an existing electronic eye for visual analysis, such as the IRIS electronic eye. In this embodiment, the image information of the dialysate in the detection pot 4 is collected in real time by the electronic eye, and analyzed in combination with the existing visual imaging technology, and the properties of the dialysate, that is, the turbidity and color, are analyzed in real time. When the dialysate becomes turbid or the color changes, that is, the color changes from colorless to other colors, the clarity of the dialysate is judged to be abnormal, and then a signal is sent to the alarm component to sound an alarm through the alarm component.

[0040] Specifically, the drainage tube 2 is detachably connected to the collection bag 3 to facilitate replacement.

[0041] Specifically, the main conduit 1 is detachably connected to the liquid inlet bag 10, so as to facilitate replacement.

[0042] Specifically, the collection bag 3 and the liquid inlet bag 10 are both disposable drainage bags, which are convenient for replacement and save costs.

[0043] Specifically, the end of the drainage tube 2 connected to the main catheter 1 is tilted toward the end of the main catheter 1 inserted into the patient's abdominal cavity, so that the dialysate flows more smoothly when the dialysate is injected and drained.

[0044] Based on the above implementation, in a specific implementation, as Figure 1 As shown, the detection component also includes a second detection component 6, which is communicatively connected to the alarm component; the second detection component 6 is arranged on the drainage tube 2, and is suitable for detecting the liquid flow rate in the drainage tube 2.

[0045] In this embodiment, the second detection member 6 detects the liquid flow rate in the drainage tube 2, and the flow rate of the dialysate being led out of the patient's peritoneal cavity can be determined by the liquid flow rate. The flow rate of the dialysate being led out of the patient's peritoneal cavity should not be too fast to prevent the greater omentum from flowing into the main catheter 1 along the dialysate, which would affect the accuracy of the detection by the first detection member 5. At the same time, the flow rate can be used to determine whether the dialysate is poorly drained or completed. In a specific application, a first flow rate threshold and a second flow rate threshold can be set in the second detection member 6, and the second flow rate threshold is smaller than the first flow rate threshold. When the dialysate is led out, During the process of dialysate being drawn out of the patient's peritoneal cavity, when the second detection component 6 detects that the flow rate of the dialysate being drawn out of the patient's peritoneal cavity is greater than the first flow rate threshold, it is judged that the liquid flow rate is abnormal, and then a signal is sent to the alarm component to issue an alarm through the alarm component for timely adjustment; when the second detection component 6 detects that the flow rate of the dialysate being drawn out of the patient's peritoneal cavity is less than the second flow rate threshold, it is judged that the liquid flow rate is abnormal, and there is a situation where the dialysate drainage is not smooth and the dialysate is not drawn out, and then a signal is sent to the alarm component to issue an alarm through the alarm component for timely adjustment.

[0046] Based on the above implementation, in a specific implementation, the second detection component 6 is a flow meter.

[0047] In this embodiment, the second detection member 6 uses a flow meter to measure the flow rate of the liquid in the drainage tube 2 to improve the detection capability.

[0048] Specifically, the second detection member 6 is arranged at the liquid inlet end of the detection pot 4, and the second detection member 6 is integrated and integrated, and has a compact structure, reduces costs, and is easy to use.

[0049] Based on the above implementation, in a specific implementation, as Figure 1 As shown, the peritoneal dialysis device further includes a wireless communication component 11 ; the first detection component 5 and the second detection component 6 are both communicatively connected to the wireless communication component 11 , and are suitable for transmitting information to an external device through the wireless communication component 11 .

[0050] In this embodiment, the first detection member 5 and the second detection member 6 are connected via the wireless communication component 11, and the detection information of the first detection member 5 and the second detection member 6 can be remotely sent to an external device, such as a computer, server, mobile phone or tablet computer, via the wireless communication component 11, thereby improving convenience and timely understanding the condition of the dialysate.

[0051] Specifically, the wireless communication component 11 can send data to an external device via Wi-Fi, Bluetooth, infrared, NFC, wireless communication network, etc.

[0052] Based on the above implementation, in a specific implementation, as Figure 1 As shown, the detection pot 4 is a Mofei drip pot.

[0053] In this embodiment, the detection pot 4 is a Moffitt drip pot, which is convenient for accumulating a certain volume of dialysate inside the Moffitt drip pot when the dialysate flows through, and the liquid level is maintained at about two-thirds, which is convenient for the first detection component 5 to perform detection, improve the detection accuracy, and avoid the dialysate flow rate in the drainage tube 2 being too fast to affect the detection effect of the first detection component 5.

[0054] On the basis of the above implementation manner, in a specific implementation manner, the capacity of the Moffitt drip pot is 5ml-10ml.

[0055] In this embodiment, the capacity of the Moffitt drip pot is 5-10ml, and the structure is small, which is convenient for operation and carrying, improves convenience, and has low cost. The capacity of the Moffitt drip pot can be selected to be 5ml, 8ml or 10ml, and the specific selection can be made according to actual conditions.

[0056] Based on the above implementation, in a specific implementation, as Figure 1 As shown, the alarm component includes at least one of an alarm light 7 and a buzzer 8 .

[0057] In this embodiment, the alarm component includes at least one of an alarm light 7 and a buzzer 8. The alarm light 7 can be used for light warning, and the buzzer 8 can be used for sound warning to improve the warning effect. The alarm light 7 and the buzzer 8 can also be used in combination to warn at the same time to further improve the warning effect, so as to facilitate timely feedback of abnormal situations.

[0058] On the basis of the above-mentioned implementation manner, in a specific implementation manner, a third detection component 13 is provided on the main conduit 1, and the third detection component 13 is communicatively connected with the alarm component; the third detection component 13 is located between the main conduit 1 and the drainage tube 2 to improve the detection accuracy, and is suitable for detecting the liquid inlet flow rate of the main conduit 1.

[0059] In this embodiment, the inlet flow rate of the main duct 1 is detected by the third detection component 13, and the inlet flow rate of the main duct 1 can be detected in real time. When the inlet flow rate is too fast, the third detection component 13 transmits information to the alarm component, so that the alarm component issues an alarm to facilitate timely adjustments to avoid discomfort to the patient caused by the excessive inlet flow rate. In specific applications, a third flow rate threshold can be set in the third detection component 13. When the third detection component 13 detects that the inlet flow rate is greater than the third flow rate threshold, the alarm component issues an alarm.

[0060] Specifically, the third detection component 13 is a flow meter, which is convenient for detecting the inlet flow rate of the main conduit 1.

[0061] Based on the above implementation, in a specific implementation, as Figure 2 As shown, a three-way valve 9 is provided on the main conduit 1 , and the main conduit 1 is connected to the drainage tube 2 through the three-way valve 9 .

[0062] In this embodiment, a three-way valve 9 is provided at the connection between the main catheter 1 and the drainage tube 2, and the main catheter 1 is connected to the drainage tube 2 through the three-way valve 9. The three-way valve 9 can be used to control the inlet bag 10 to be connected to the end of the main catheter 1 inserted into the patient's abdominal cavity to facilitate the infusion of dialysate, or control the collection bag 3 to be connected to the end of the main catheter 1 inserted into the patient's abdominal cavity to facilitate the withdrawal of dialysate. There is no need to use an external clamping device 12 for clamping, which is convenient and quick.

[0063] The specific working principle of a peritoneal dialysis device provided in this embodiment is as follows: when performing dialysis, one end of the main catheter 1 is placed in the patient's abdominal cavity, and the other end is connected to the fluid inlet bag 10. First, the pipeline between the main catheter 1 and the detection component on the drainage tube 2 can be clamped by an external clamping device 12 such as a clamp, or a three-way valve 9 is used to prevent the main catheter 1 from being connected to the drainage tube 2, and the fluid inlet bag 10 is connected to the patient's abdominal cavity through the main catheter 1 to prevent the collection bag 3 from being connected to the main catheter 1, resulting in new dialysate flowing into the collection bag 3. Then, the fluid inlet bag 1 is connected to the main catheter 1. 0 is placed at a position higher than the patient's abdominal cavity. Under the action of gravity, the dialysate in the inlet bag 10 is poured into the patient's abdominal cavity through the main catheter 1. After the dialysate is stored in the abdominal cavity for 3-4 hours, the external clamping device 12 on the drainage tube 2 is loosened, and then the pipeline between the drainage tube 2 and the inlet bag 10 on the main catheter 1 is clamped by the external clamping device 12, such as a clamp, or the three-way valve 9 is used to make the main catheter 1 and the drainage tube 2 conductive, and the main catheter 1 and the inlet bag 10 not conductive, so as to prevent the inlet bag 10 from communicating with the drainage tube 2. The outflow of the dialysate in the abdominal cavity is affected. Then, the drainage tube 2 and the collection bag 3 are placed at a position lower than the patient's abdominal cavity. The siphon principle is used to make the dialysate in the abdominal cavity flow out of the abdominal cavity under the action of gravity. In this process, the second detection component 6 detects the outflow rate of the liquid on the drainage tube 2 in real time. When the outflow rate of the liquid is abnormal, an alarm is sounded through the alarm component. At the same time, when the dialysate passes through the detection pot 4, a certain volume of dialysate is accumulated in the detection pot 4, so as to avoid the failure to timely detect the properties of the dialysate when the dialysate flows through the drainage tube 2, thereby improving the accuracy of the detection. The first detection component 5 detects the clarity of the dialysate in the detection pot 4 in real time, such as the turbidity and color of the dialysate. If the first detection component 5 detects that the turbidity or color of the dialysate is abnormal, a signal is transmitted to the alarm component, and an alarm signal is issued through the alarm component to prompt the patient or other accompanying personnel, so as to find the abnormality in time, help the patient identify peritonitis as early as possible, so as to seek medical treatment in time, improve the degree of intelligence, save time and effort, avoid errors caused by manual observation, and have high detection accuracy, which is convenient and simple. The technical problem that the existing peritoneal dialysis machine needs to manually observe the clarity of the dialysate, which is time-consuming and labor-intensive, and it is difficult to accurately identify whether the dialysate has abnormalities, which is easy to delay the treatment time is solved.

[0064] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
