[0024] A method for using a hemodialysis monitoring and nursing instrument according to any one of claims 1-9, characterized in that it includes the following steps:

[0025] S1. Medical staff set a retention needle on the patient's arm, and then the patient places the arm with the indwelling needle in the arm support groove to contact the massage rod.

[0026] S2. Medical staff connect the arterial hose on the dialysis device to the one-way connector at one end of the relay tube, and connect the retention needle on the patient's arm to the other one-way connector, so as to form blood circulation by connecting the arterial hose and the human body.

[0027] S3. Limit the relay tube in the relay tube installation limit groove, and lead out the end of the relay tube close to the patient from the lead tube groove and limit it by the limit elastic piece.

[0028] S4. Install a monitoring device on the patient, and lead out the pipeline of the monitoring device from the lead tube groove and the relay tube installation limit groove.

[0029] S5. The patient starts the linear motor through a remote control, a manual switch or a timing device. The linear motor slowly drives the sliding frame to move back and forth, driving the massage rod to slowly push the muscles of the patient's arm to relieve the discomfort of the patient's arm.

[0030] S6. When the patient's arm needs further limitation or cooling, by installing a limit protection mechanism, align the support legs on the limit protection mechanism with the lead tube groove and press down. The limit elastic piece deforms to clamp the support legs to fix the triangular support frame, reducing the distance that the arm can be lifted up.

[0031] S7. Connect the power supply to make the fan in the limit plate work to blow air downward for cooling.

[0032] When the patient temporarily needs to interrupt dialysis, separate the indwelling needle from the one-way connector, and interconnect the two one-way connectors at the end close to the patient to enable the dialysis equipment to circulate on its own to avoid blood coagulation. When continuing dialysis, simply reconnect the indwelling needle to the one-way connector.

[0033] As described above, a hemodialysis monitoring and nursing instrument of the present invention has the following beneficial effects:

[0034] 1. By arranging a driving part installation groove inside the arm support frame of the present invention, and opening a limiting sliding groove inside the arm support groove, a linear motor is installed at the inner bottom of the driving part installation groove to drive the sliding frame to perform reciprocating motion in the horizontal direction, so as to drive the massage rod to massage the patient's arm, thereby improving the comfort of the patient during dialysis treatment.

[0035] At the same time, a telescopic groove is arranged on the connecting plate, and the telescopic groove is adapted to the position of the massage rod. When the patient places the arm, the massage rod can compress the telescopic groove according to the different diameters of the patient's arm, so as to adapt to patients with different arm diameters and adapt to the change of arm thickness during massage.

[0036] 2. By arranging a plurality of massage rods and distributing the massage rods along the arc of the arm support groove of the present invention, when the patient's arm is placed between the massage rods, the lower row of massage rods contacts the patient's arm from the side, and the upper row of massage rods rests on the upper part of the patient's arm to limit the arm. During massage, the massage rod can limit the patient's arm to avoid accidental movement of the patient's hand resulting in needle removal.

[0037] 3. By arranging relay pipe installation limiting grooves on both sides of the top of the arm support frame of the present invention, arranging a pipe guiding groove on the side of the relay pipe installation limiting groove close to the arm, and arranging limiting elastic pieces on both sides of the inner wall of the pipe guiding groove, and cooperating with the relay pipe installation limiting groove to fix and limit the relay pipe. During dialysis, the indwelling needle on the patient's arm and the arterial hose on the dialysis equipment are connected through the one-way connector on the relay pipe. When the patient temporarily needs to interrupt dialysis, the indwelling needle can be separated from the one-way connector, avoiding the problems of needle removal and the need to reinsert the needle after needle removal, and improving comfort and convenience.

[0038] At the same time, due to the limitation of the relay pipe installation limiting groove and the pipe guiding groove, the position of the relay pipe is restricted, which can effectively avoid the hose from bending and winding.

[0039] 4. By arranging a limiting protection mechanism, when the patient undergoes long-term dialysis, the sleeping patient's arm can be further limited by the limiting protection mechanism to avoid the increase in the amplitude of the patient's arm movement during sleep. At the same time, the fan (405) in the limiting plate is started to blow air to cool the patient's arm, which can effectively reduce the patient's pain.

[0040] Therefore, the present invention effectively overcomes various drawbacks in the prior art and has high industrial utilization value. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification

[0058] Please refer to Figures 1 to 10 . It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention. Therefore, they do not have technical essential meanings. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present invention can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this specification are only for the convenience of clear description and are not used to limit the scope for the implementation of the present invention. The change or adjustment of their relative relationships, without substantial change of the technical content, should also be regarded as the scope for the implementation of the present invention

[0059] As Figures 1 - 3 shown, the present invention provides a hemodialysis monitoring and nursing instrument, including a support arm frame 1 and a linear motor 2. The support arm frame 1 is used to support the patient's arm, and the linear motor 2 is used to provide power during massage

[0060] Specifically, an arm support groove 101 is provided at the top of the support arm frame 1, and the arm support groove 101 is used to limit the patient's arm. A driving part installation groove 102 is provided inside the support arm frame 1, and mechanical equipment is installed inside the driving part installation groove 102. A limit sliding groove 103 communicating with the inside of the driving part installation groove 102 is provided on the inner wall of the arm support groove 101

[0061] On both sides of the top arm support groove 101 of the support arm 1, relay pipe installation limit grooves 104 are provided. During dialysis, the arterial hose can be guided through the relay pipe installation limit grooves 104, reducing the entanglement and twisting between the arterial hoses and improving the smoothness of blood circulation. On the side of the relay pipe installation limit groove 104 facing the arm support groove 101, a number of pipe guiding grooves 105 are equidistantly arranged. After being guided by the relay pipe installation limit groove 104, the arterial hose is led out from the position of the pipe guiding groove 105 to contact the patient's arm. The arm lengths of people of different ages and body types are different, and the blood drawing and blood transfusion positions are different. Therefore, a number of equidistantly distributed pipe guiding grooves 105 are provided to adapt to different populations.

[0062] The linear motor 2 is arranged at the inner bottom of the arm support groove 101. The linear motor 2 is powered by a lithium battery or an external power supply, and the working mode of the linear motor 2 is controlled by a control circuit board. A sliding frame 201 is arranged on the linear motor 2. After the linear motor 2 is powered on, a magnetic field that drives the sliding frame 201 is generated, enabling the linear motor 2 to drive the sliding frame 201 to reciprocate along the track of the linear motor 2. A plurality of massage rods 202 are arranged on the surface of the sliding frame 201, and all the massage rods 202 penetrate through the limit sliding groove 103 to the inside of the arm support groove 101. After the patient's arm is placed inside the arm support groove 101, it will directly contact the massage rods 202. When the sliding frame 201 moves, the massage rods 202 will move along with the movement of the sliding frame 201 to massage the patient's arm to relieve the discomfort of the patient's arm.

[0063] As Figure 4 shown, in some embodiments, the sliding frame 201 of the present invention includes a motor connection rail 2011. The motor connection rail 2011 is restricted on the linear motor 2 and magnetically coupled. A magnetic block is arranged inside the motor connection rail 2011. The magnetic block interacts with the electromagnetic field of the linear motor 2 to drive the sliding frame 201 to move and guide and limit the moving direction of the sliding frame 201. A connecting plate 2012 is arranged on the top of the motor connection rail 2011. The connecting plate 2012 has an arc shape adapted to the arm support groove 101 for supporting the massage rods 202. Telescopic grooves 2013 are arranged on both sides of the connecting plate 2012. The telescopic grooves 2013 are arranged along the arrangement direction of the massage rods 202. When the massage rods 202 are pressed, the telescopic grooves 2013 can deform inward, thereby changing the distance between the two side massage rods 202 to adapt to different arm diameters. The pressure required to directly deform the entire connecting plate 2012 is smaller. And the reaction force is also smaller, and the patient's arm will not generate a strong clamping pain.

[0064] Specifically, at least two rows of massage rods 202 are arranged on each side, and the lower row contacts the lower side of the arm. When the arm falls into the bottom of the arm support groove 101, the upper row of massage rods 202 rebound under the action of elasticity and contact the upper edge of the arm to restrict the arm. When the massage rods 202 are used for massage, the upper row of massage rods 202 can exert a small amount of restraining force on the arm to prevent the arm from unconsciously moving and causing the needle to fall off.

[0065] It is worth noting that the connecting plate 2012 of the present invention is made of memory metal and has elasticity. The memory metal helps the expansion slot 2013 return to its original state after deformation. When the massage rod 202 is compressed, the connecting plate 2012 can deform under the elastic force and exert a reaction force on the massage rod 202, so that the massage rod 202 always contacts the arm.

[0066] like Figure 3 and Figure 4 As shown, in some embodiments, the ends of all massage rods 202 of the present invention are provided with rollable protective balls 203, and the protective balls 203 are in direct contact with the patient's arm. When the massage rod 202 moves repeatedly to massage the patient's arm, the protective balls 203 will roll, thereby reducing the friction between the skin, avoiding skin damage and improving comfort. The inner bottom of the arm support groove 101 is provided with a soft hand rest 107 for supporting the bottom of the patient's arm. Avoid pain and discomfort caused by the arm contacting the hard arm support groove 101 for a long time.

[0067] like Figure 5 As shown, in some embodiments, the palm rest 107 of the present invention includes a foreskin sponge pad 1071 , and a honeycomb hole 1072 is provided inside the foreskin sponge pad 1071 .

[0068] Through the above technical solution, the foreskin sponge pad 1071 can provide a comfortable support for the arm, and the honeycomb hole 1072 can make the foreskin sponge pad 1071 have better deformability to further improve comfort. At the same time, the foreskin sponge pad 1071 and the honeycomb hole 1072 can cooperate to have better sweat absorption.

[0069] like Figure 2 and Figure 7As shown, in some embodiments, elastic limiting elastic pieces 106 are provided on both sides of the inner wall of the pipe guiding groove 105 of the present invention. The two limiting elastic pieces 106 can achieve the effect of clamping and limiting through their own elasticity. A relay pipe 3 is arranged inside the pipe guiding groove 105, and the relay pipe 3 can be limited by the limiting elastic pieces 106. One-way connectors 301 are arranged at both ends of the relay pipe 3. A rubber pad is arranged at the mouth of the one-way connector 301 for sealing. Thus, only when the needle penetrates the rubber pad can the liquid flow, and after the needle is pulled out, the rubber pad achieves the effect of intercepting the flow. One of the one-way connectors 301 is connected to the arterial hose led out by the dialysis device outside the support arm 1 along the installation limiting groove 104 of the relay pipe. The other one-way connector 301 extends into the inner part of the arm support groove 101 along the pipe guiding groove 105 and is connected to the indwelling needle on the patient's arm. The relay pipe 3 is arranged in two, one is used as an input pipe and the other is used as an output pipe to form blood circulation.

[0070] Through the above technical solution, during the long-term dialysis process of the patient, if it is necessary to temporarily terminate dialysis, the indwelling needle on the arm can be separated from the one-way connector 301. There is no need to pull out the needle in the traditional way and then insert the needle again when the patient comes back. It can improve the convenience of the operation of medical staff and reduce the pain of the patient.

[0071] As Figure 6 shown, in some embodiments, the hemodialysis monitoring and nursing instrument of the present invention further includes a limiting and protecting mechanism 4, and the limiting and protecting mechanism 4 is fixed through the cooperation of the pipe guiding groove 105 and the limiting elastic pieces 106.

[0072] Through the above technical solution, when the patient undergoes dialysis for a long time, having nothing to do will make the patient feel nervous and scared. At this time, by installing the limiting and protecting mechanism 4 and blocking the arm through the limiting and protecting mechanism 4, the nervousness of the patient can be reduced. And when the patient is asleep, by installing the limiting and protecting mechanism 4, the activity space of the patient's arm can be reduced. To avoid excessive movement of the patient's sleeping arm and the indwelling needle cannot be effectively blocked by the massage rod 202 resulting in needle removal.

[0073] As Figure 8 、 10 shown, in some embodiments, the limiting and protecting mechanism 4 of the present invention includes four triangular support frames 401, and a support leg 402 is arranged at the bottom of each triangular support frame 401. The support leg 402 can be limited in the pipe guiding groove 105. When installing, it can be directly inserted and pulled out to achieve the purpose of convenient operation. And hoses and the like can pass through between the pipe guiding groove 105 and the support leg 402 without affecting the wiring.

[0074] There is a limit plate 403 between the four triangular support frames 401. The limit plate is used to limit the space for the arm to move up and down, thereby preventing the unconscious lifting of the arm of a sleeping patient, which may cause the needle to fall off, and also preventing other people or objects from touching the dialysis tube on the arm. A plurality of through air guiding grooves 404 are provided in the middle of the limit plate 403, and a cooling fan 405 is provided inside each air guiding groove 404. A power socket is provided on the side of the limit plate 403 to connect with the cooling fan 405. While restricting the lifting of the patient's arm, the cooling fan 405 can blow air on the patient's arm, thereby reducing the temperature of the patient's arm and alleviating the patient's pain. Moreover, the air blown towards the hose can reduce the temperature of the hose, thereby reducing the speed of blood coagulation.

[0075] As Figure 6 , 9 shown, in some embodiments, an auxiliary support device 5 is provided in the middle of the upper end surface of the limit plate 403 of the present invention. The auxiliary support device 5 includes two fixing frames 501, and the two fixing frames 501 are symmetrically arranged on both sides of the limit plate 403.

[0076] A swing arm 503 is arranged between the two fixing frames 501. Damping rotating shafts 502 are arranged at both ends of the swing arm 503, and the two damping rotating shafts 502 are respectively hinged to the fixing frames 501 on both sides.

[0077] A plug-in slot 504 is arranged at the top of the swing arm 503. The two wall surfaces of the plug-in slot 504 are arranged at different heights, so that the object clamped by the plug-in slot 504 can be fixed obliquely. Moreover, the two wall surfaces of the plug-in slot 504 are both elastic, and the clamping effect is achieved through the elastic deformation; a magnetic plate 505 is arranged on the inner wall of the higher wall surface of the plug-in slot 504 to adsorb the object to be fixed by magnetic attraction.

[0078] By fixing an entertainment device (mobile phone) on the auxiliary support device 5, the discomfort of the patient can be alleviated, and when the patient undergoes dialysis for a long time, the situation of having nothing to do and generating nervous and fearful emotions can be avoided.

[0079] The specific use process of the present invention is as follows:

[0080] S1. The medical staff set a retention needle on the patient's arm, and then the patient places the arm with the indwelling needle in the arm support groove 101 to contact the massage rod 202.

[0081] S2. The medical staff connect the arterial hose on the dialysis device with the one-way connector 301 at one end of the relay tube 3, and connect the retention needle on the patient's arm with the other one-way connector 301, so as to form blood circulation by connecting the arterial hose and the human body.

[0082] S3. Limit the relay tube 3 in the relay tube installation limiting groove 104, and lead out the end of the relay tube 3 close to the patient from the lead tube groove 105 and limit it through the limiting elastic piece 106;

[0083] S4. Install monitoring equipment on the patient, and lead out the pipelines of the monitoring equipment from the lead tube groove 105 and the relay tube installation limiting groove 104;

[0084] S5. The patient starts the linear motor 2 through a remote control, a manual switch or a timing device. The linear motor 2 slowly drives the sliding frame 201 to perform reciprocating motion, driving the massage rod 202 to slowly push the muscles of the patient's arm to relieve the discomfort of the patient's arm;

[0085] S6. When the patient's arm needs further limitation or cooling, install the limit protection mechanism 4. Align the support legs 402 on the limit protection mechanism 4 with the lead tube groove 105 and press down. Through the deformation of the limit elastic piece 106, the support legs 402 are clamped to fix the triangular support frame 401, reducing the distance that the arm can be lifted;

[0086] S7. Connect the power supply to make the fan 405 in the limit plate 403 work to blow air downward for cooling;

[0087] When the patient temporarily needs to interrupt dialysis, separate the indwelling needle from the one-way connector 301, and interconnect the two one-way connectors 301 at the end close to the patient to make the dialysis equipment circulate by itself to avoid blood coagulation. When continuing dialysis, connect the indwelling needle to the one-way connector 301 again.

[0088] In summary, for the hemodialysis monitoring and nursing instrument of the present invention, by arranging a driving part installation groove 102 inside the arm support 1, arranging a limiting sliding groove 103 inside the arm support groove 101, and installing a linear motor 2 at the inner bottom of the driving part installation groove 102 to drive the sliding frame 201 to perform reciprocating motion in the horizontal direction, the massage rod 202 is driven to massage the patient's arm, so as to improve the comfort of the patient during dialysis treatment.

[0089] At the same time, a telescopic groove 2013 is arranged on the connecting plate 2012, and the telescopic groove 2013 is adapted to the position of the massage rod 202. When the patient places the arm, the massage rod 202 can compress the telescopic groove 2013 according to the different diameters of the patient's arm, so as to adapt to patients with different arm diameters and adapt to the change of arm thickness during massage.

[0090] In the present invention, a plurality of massage rods 202 are provided and distributed along the arc of the arm support groove 101. When the patient's arm is placed between the massage rods 202, the lower row of massage rods 202 contacts the patient's arm from the side, while the upper row of massage rods 202 is placed on the upper part of the patient's arm to limit the arm. During massage, the massage rods 202 can limit the patient's arm to prevent the patient's hand from moving unconsciously and causing needle dislodgment.

[0091] In the present invention, relay tube installation limit grooves 104 are provided on both sides of the top of the arm support 1, pipe guiding grooves 105 are provided on the side of the relay tube installation limit grooves 104 close to the arm, and limit elastic pieces 106 are provided on both sides of the inner wall of the pipe guiding grooves 105 to cooperate with the relay tube installation limit grooves 104 to fix and limit the relay tube 3. During dialysis, the retention needle on the patient's arm and the arterial hose on the dialysis device are connected through the one-way connector 301 on the relay tube 3. When the patient temporarily needs to interrupt dialysis, the retention needle can be separated from the one-way connector 301, avoiding the problems of needle removal and the need for reinsertion after needle removal, and improving comfort and convenience.

[0092] At the same time, due to the limitation of the relay tube installation limit grooves 104 and the pipe guiding grooves 105, the position of the relay tube 3 is restricted, effectively avoiding hose bending and winding.

[0093] In the present invention, a limit protection mechanism 4 is provided. When the patient undergoes long-term dialysis, the limit protection mechanism 4 can further limit the arm of the sleeping patient to prevent the arm movement amplitude of the patient from becoming larger during sleep. At the same time, the fan 405 in the limit plate 403 is started to blow air to cool the patient's arm, which can effectively reduce the pain of the patient and cool the hose. According to research, for every one-degree decrease in temperature, the blood coagulation rate can be slowed down by 8%, which can reduce the blood coagulation rate.

[0094] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0095] The above embodiments are only illustrative of the principles and effects of the present invention and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
