Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a device for protecting intravenous drug extravasation in leukemia chemotherapy patients. Background Art

[0002] When leukemia patients undergo chemotherapy, they will need intravenous infusion. During the process of intravenous infusion, extravasation of infused drugs may occur due to the patient's own activities or improper puncture and fixation by medical staff. Leukemia patients have poor physical conditions and perception due to long-term illness, repeated chemotherapy, and medication. They may not notice drug extravasation at the first time. Chemotherapy drugs are highly irritating, such as anthracyclines and vinca alkaloids. Once they extravasate into the surrounding skin, they will cause serious skin damage. In addition, intravenous injection is a continuous process. When drug extravasation occurs, if the intravenous infusion is not stopped at the first time, the continuously injected chemotherapy drugs will continue to erode the surrounding skin, further expanding the scope of skin necrosis at the extravasation site. For example, what was originally just a small area of ​​redness and swelling will gradually develop into a large area of ​​ulcers and skin necrosis, which will not only cause harm to leukemia patients, but also cause waste of chemotherapy drugs.

[0003] Therefore, a device for protecting intravenous drug extravasation in leukemia chemotherapy patients was proposed. Summary of the invention

[0006] Furthermore, it also includes a lifting alarm component arranged on the infusion table, the lifting alarm component includes multiple electric telescopic rods, the telescopic ends of the multiple electric telescopic rods are fixedly connected to the bottom surface of the infusion table, the fixed ends of the multiple electric telescopic rods are commonly fixedly connected to a bottom plate, the end of another square column away from the side plate that is not fixed to the vertical plate is fixedly connected to a cross plate, two trigger blocks are installed on the slide plate close to one side of the cross plate, two switches are installed at the positions of the two trigger blocks on the side of the cross plate close to the slide plate, and a buzzer is installed on the side of the cross plate away from the switches.

[0007] Furthermore, it also includes four anti-tampering components arranged at the four corners of the side wall of the infusion table, the anti-tampering components include a rotating shaft, the rotating shaft is fixedly connected to the side wall of the infusion table, an L-shaped rod is rotatably connected to the surface of the rotating shaft, a rubber block is fixedly connected to the L-shaped rod, a torsion spring is fixedly connected between the L-shaped rod and the rotating shaft, and a magnet is fixedly connected to the bottom plate.

[0008] Furthermore, two ends of the two springs are fixedly connected to the slide plate and the side plate on the same side respectively.

[0009] Furthermore, the two pressing plates are both inclined toward the side close to the side plate.

[0010] Furthermore, the transverse rack and the vertical rack are staggered, the transverse rack is meshed with the bottom of the gear, and the vertical rack is meshed with the side of the gear away from the side plate.

[0011] Furthermore, two ends of the two springs three are fixedly connected to the vertical rack and the lifting plate respectively, and the infusion tube passes through the top and bottom ends of the control shell.

[0013] Furthermore, the two switches are located on the moving paths of the two trigger blocks, and the two switches are electrically connected to the electric telescopic rod and the buzzer through an external controller.

[0014] Furthermore, a side of the rubber block away from the L-shaped rod is configured as a curved surface.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By monitoring the extravasation of intravenous drugs in patients through absorbent paper and triggering subsequent structures, the flow of drugs inside the infusion tube is cut off, so that intravenous infusion can be stopped immediately to prevent the patient from failing to detect the extravasation of drugs in time, resulting in the continued extravasation of chemotherapy drugs, and the further expansion of the skin necrosis at the extravasation site. This can stop the chemotherapy drugs and avoid the waste of chemotherapy drugs.

[0017] By monitoring the extravasation of intravenous drugs in patients with absorbent paper, the chemotherapy drugs that have seeped out of the patient's skin surface can be absorbed immediately, which can prevent the accumulation of such drugs on the patient's skin surface and reduce the concentration of drugs in the local skin, thereby reducing the irritation of the drugs to the surrounding skin. At the same time, it can prevent the drugs from further eroding the surrounding skin and reduce the possibility of skin necrosis.

[0018] The patient's affected limb is also raised above the patient's heart by the top of the infusion table. Raising the affected limb can use gravity to promote the return of blood and skin fluid from the extravasation site to the heart, which helps reduce the accumulation of extravasated drugs in the local skin, thereby reducing blood vessel swelling caused by drug extravasation. At the same time, by promoting blood return and reducing swelling, pain can also be relieved accordingly. Raising the affected limb can make the extravasated drugs flow toward the heart under the action of gravity instead of continuing to spread to the surrounding skin. This helps control the scope of drug extravasation and reduce damage to more skin.

[0019] The buzzer is controlled by an external controller to sound an alarm, which can attract the attention of medical staff as soon as drug extravasation occurs, so that medical staff can deal with it in time. Compared with relying on regular inspections by medical staff or patients calling after discovering the problem themselves, it can achieve the effect of timely reminder and avoid aggravating the patient's condition due to delayed treatment;

[0020] The curved surface of the rubber block and the straightened torsion spring exert inward pressure on the L-shaped rod, so that the rubber block and the patient's affected limb collide with each other and exert pressure on each other. The anti-slip surface of the rubber block can enhance the friction between the rubber block and the affected limb. At this time, the patient is lifted to a height higher than the heart, and the affected limb is fixed in position by four rubber blocks, which avoids the patient panicking and causing the affected limb to move randomly during the process of lifting the affected limb, thereby ensuring the safety of the patient's affected limb during the lifting process.

[0021] The affected limb is fixed by four rubber blocks. During the lifting process of the affected limb, it can be ensured that the affected limb is lifted horizontally in accordance with the infusion table, so that the patient's blood vessels are in a more natural state, avoiding the tilt or twisting of blood vessels caused by the patient's movement and affecting the blood flow. At the same time, it can make all parts of the affected limb be evenly affected by gravity, thereby promoting blood return. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiments provided by the present invention:

[0040] Embodiment 1:

[0041] See also Figures 1 to 7As shown, the intravenous drug extravasation protection device for leukemia chemotherapy patients includes a monitoring and stopping liquid component, which includes an infusion platform 11 and two side panels 12. The two side panels 12 are symmetrically fixedly connected to the two sides of the infusion platform 11. The tops of the two side panels 12 that are away from each other are fixedly connected with a square column 13. A slide plate 14 is slidably connected to each of the two square columns 13. A spring 15 is sleeved on the surface of each of the two square columns 13. The two ends of the two springs 15 are fixedly connected to the slide plate 14 and the side panel 12 on the same side, respectively. The slide plate 14 is set in an "L" shape. The slide plate 14 The vertical surface of the square column 13 is slidably connected, and the top surfaces of the horizontal surfaces of the two slides 14 are fixedly connected to multiple springs 16, and the tops of the multiple springs 16 on the same side are commonly fixedly connected to a pressure plate 17, and the two pressure plates 17 are both set in a "Z" shape. The lower surface of the top of the pressure plate 17 is fixedly connected to the top of the spring 16, and an absorbent paper 18 is sandwiched between the upper surface of the horizontal surface of the slides 14 on both sides and the lower surface of the bottom of the pressure plate 17. One end of one of the square columns 13 away from the side plate 12 is fixedly connected to a vertical plate 19, and a connecting block is fixedly connected to the middle side wall of the vertical plate 19 110, the connecting block 110 is set in a "U" shape, the middle side wall of the connecting block 110 close to the side of the vertical plate 19 is rotatably connected to the gear 111, the horizontal surface of the slide plate 14 close to the side of the vertical plate 19 is fixedly connected to the top surface of the side of the spring 2 16, and the end of the connecting block 110 away from the side of the vertical plate 19 and close to the gear 111 is connected to the vertical rack 113 in an up and down sliding manner, the horizontal rack 112 and the vertical rack 113 are staggered, the horizontal rack 112 and the bottom of the gear 111 are meshed with each other, and the vertical rack 113 and the side of the gear 111 away from the side plate 12 are mutually meshed. The top of the vertical rack 113 is meshed with each other and is symmetrically and slidably connected to two guide columns 114. The two guide columns 114 are fixedly connected to a lifting plate 115 at one end close to the infusion table 11. A spring three 116 is respectively sleeved on the surface of the two guide columns 114. The two ends of the two spring three 116 are respectively fixedly connected to the vertical rack 113 and the lifting plate 115. A control shell 21 is provided at the top of the vertical plate 19. A rotating wheel 22 is slidably connected to the inside of the control shell 21. An infusion tube 23 is slidably connected to the control shell 21, and the infusion tube 23 passes through the top and bottom of the control shell 21.

[0042] It should be noted that the infusion site here takes the elbow fossa where intravenous infusion is commonly used in the human body, that is, the connection between the forearm and the upper arm of the upper limb as an example. Leukemia chemotherapy patients usually receive infusion in a lying position.

[0043] Among them: the control shell 21, the rotating wheel 22, and the infusion tube 23 are all existing known technologies, and the control shell 21 and the rotating wheel 22 are combined to form a drip rate regulator in the prior art. It should be noted that in the accompanying drawings, the infusion tube 23 is partially displayed, and only the connection part with the control shell 21 and the rotating wheel 22 is displayed. When in use, the medical staff adjusts the position of the control shell 21 on the infusion tube 23 so that the control shell 21 is located at one end of the infusion tube 23 close to the patient's intravenous infusion, and fixes the control shell 21 to the top of the vertical plate 19 by means of medical tape or buckles. This is because the control shell 21, the rotating wheel 22, and the infusion tube 23 are usually disposable items, which will be replaced with a new batch for use after use, and the detachable installation can increase the versatility of the device.

[0044] Wherein: the control housing 21 is set to a right-angled trapezoid shape that increases from top to bottom, and the rotating wheel 22 slides on the inclined side of the right-angled trapezoid of the control housing 21. When the rotating wheel 22 is at the top inside the control housing 21, the squeezing deformation force of the rotating wheel 22 on the infusion tube 23 is the largest, so that the infusion tube 23 is cut off, and then the infusion tube 23 no longer infuses the patient's vein.

[0045] Among them: Figure 2 , Figure 4 As shown, the lifting plate 115 abuts against one side of the opening of the control housing 21 . The opening of the control housing 21 is designed to be inclined. The lifting plate 115 and the inclined side of the control housing 21 have complementary inclination angles and are slidably adapted.

[0046] Among them: the pulp fibers inside the absorbent paper 18 are tightly bound and arranged relatively neatly before absorbing water. The fibers themselves have certain strength and toughness and can withstand certain tension. After absorbing water, water molecules enter the fibers and make them swell. The distance between the fibers increases, and the arrangement becomes loose and chaotic, so they are easily broken when subjected to tension.

[0047] When a leukemia chemotherapy patient (hereinafter referred to as a patient) needs intravenous infusion, the control housing 21 is not installed on the vertical plate 19 , and the absorbent paper 18 is not clamped between the two pressing plates 17 and the slide plate 14 .

[0048] The patient places the affected limb flat on the concave part of the top surface of the infusion table 11, and places the elbow fossa in the middle of the infusion table 11, that is, at the position of the side panel 12. The medical staff then performs intravenous infusion on the patient's elbow fossa. After completion, the medical staff adjusts the control housing 21 on the infusion tube 23 to the end close to the patient's intravenous infusion, and then puts the control housing 21 aside to wait for subsequent operations.

[0049] Then, the medical staff first pulls up the pressure plate 17 on one side, so that the multiple springs 16 at the bottom of the pressure plate 17 are elastically stretched, so that an opening is exposed between the springs 16 and the pressure plate 17 on the same side, and then one end of the absorbent paper 18 is inserted into the opening. After completion, the pressure plate 17 is no longer pulled. Under the elastic contraction of the springs 16, the springs 16 and the pressure plate 17 clamp the absorbent paper 18 between them. At this time, one end of the absorbent paper 18 is clamped. Then the medical staff pushes the two slides 14 toward each other, so that the two springs 15 are elastically compressed, and repeats the above-mentioned clamping operation on the absorbent paper 18, so that the two ends of the absorbent paper 18 are clamped by the two springs 16 and the pressure plate 17 on both sides, respectively. At this time, the absorbent paper 18 is clamped. In a taut state, the lower surface of the absorbent paper 18 is attached to the patient's intravenous infusion position, and because the absorbent paper 18 itself has the property of being soft, it will not exert pressure on the patient's intravenous infusion position. The two are in a state of being attached but not exerting pressure on each other. After completion, the medical staff pulls the guide column 114 to the side away from the infusion table 11, so that the spring three 116 is elastically compressed, and at the same time uses medical tape to fix the control shell 21 to the top of the vertical plate 19, and then stops pulling the guide column 114. Under the elastic extension action of the spring three 116, the guide column 114 and the lifting plate 115 move toward the side of the control shell 21 until the lifting plate 115 hits the bottom end of the control shell 21, so that the lifting plate 115 is located on the moving path of the rotating wheel 22.

[0050] When drug extravasation occurs during the patient's intravenous infusion, the drug will penetrate from the patient's veins to the skin surface of the patient's elbow fossa. At this time, the drug is absorbed by the absorbent paper 18. The absorbent paper 18 cannot balance the pulling force applied by the springs 15 on both sides, and then the absorbent paper 18 is broken under the elastic stretching action of the springs 15 on both sides. At this time, the slides 14 on both sides slide away from each other on the square column 13 on the same side. Among them, the slide 14 on the side of the vertical plate 19 will drive the horizontal rack 112 to move synchronously during the movement. During the movement of the horizontal rack 112, the meshing drives the gear 111 to rotate. When the gear 111 rotates, it drives the vertical rack 113 to move. At this time, the vertical rack 113 is vertically upward on the surface of the connecting block 110. The vertical rack 113 drives the lifting plate 115 to move upward synchronously. During the upward movement of the lifting plate 115, since the opening side of the control shell 21 is designed to be inclined, the lifting plate 115 is always in contact with the control shell 21 under the elastic extension of the spring three 116. During this process, the lifting plate 115 is in contact with the rotating wheel 22, driving the rotating wheel 22 to slide upward inside the control shell 21. During the movement of the rotating wheel 22, the rotating wheel 22 gradually increases the degree of deformation of the part in contact with the infusion tube 23. When the spring 15 is fully elastically extended, the rotating wheel 22 slides to the top inside the control shell 21, so that the rotating wheel 22 squeezes the infusion tube 23 to cut off the flow, and no more drugs are injected into the patient's vein.

[0051] During this process, the absorbent paper 18 is used to monitor the patient's intravenous drug extravasation and trigger the subsequent structure to cut off the drug flow inside the infusion tube 23, so that the intravenous infusion can be stopped at the first time. This can prevent the patient from being unable to detect the drug extravasation in time, resulting in continuous extravasation of chemotherapy drugs, and further expansion of the skin necrosis area at the extravasation site, thereby improving the patient's treatment safety.

[0052] When the absorbent paper 18 detects extravasation of intravenous drugs from the patient, the chemotherapy drugs that have seeped out of the patient's skin surface can be absorbed immediately, which can prevent the accumulation of this part of the drugs on the patient's skin surface and reduce the concentration of the drugs in the local skin, thereby reducing the irritation of the drugs to the surrounding skin. At the same time, it can prevent the drugs from further eroding the surrounding skin and reduce the possibility of skin necrosis.

[0053] See also Figure 5 and Figures 8 to 9 As shown, when drug leakage occurs, it is difficult for medical staff to guard the patient all the time, and it is necessary to inform the medical staff in time and provide emergency protection for the patient. Therefore, a lifting alarm component is also set on the infusion table 11, and the lifting alarm component includes multiple electric telescopic rods 31, and the telescopic ends of the multiple electric telescopic rods 31 are fixedly connected to the bottom surface of the infusion table 11, and the fixed ends of the multiple electric telescopic rods 31 are commonly fixedly connected to a bottom plate 32, and the other square column 13 without a fixed vertical plate 19 is fixedly connected to the end away from the side plate 12 with a cross plate 33, and two trigger blocks 34 are installed on the slide plate 14 close to the side of the cross plate 33, and two switches 35 are installed on the side of the cross plate 33 close to the slide plate 14 corresponding to the positions of the two trigger blocks 34, and a buzzer 36 is installed on the side of the cross plate 33 away from the switch 35.

[0054] The two switches 35 are located on the moving paths of the two trigger blocks 34 , and the two switches 35 are electrically connected to the electric telescopic rod 31 and the buzzer 36 through an external controller.

[0055] When the two switches 35 are contacted by the two trigger blocks 34 , the two switches 35 control the extension of the telescopic ends of the multiple electric telescopic rods 31 through the external controller, and control the buzzer 36 to sound an alarm.

[0056] It should be noted that when the telescopic end of the electric telescopic rod 31 is extended, the infusion table 11 is lifted to a height higher than the heart height of the patient when the patient lies flat.

[0057] When the lifting alarm component is in operation, the monitoring liquid-cutting component is in operation, and the slide plates 14 on both sides are sliding away from the square column 13 on the same side. At this time, the two trigger blocks 34 move toward the two corresponding switches 35. When the two trigger blocks 34 collide with the two switches 35, the switches 35 control the extension of the telescopic ends of the multiple electric telescopic rods 31 through the external controller, so that the infusion table 11 is lifted to a height higher than the heart of the patient when lying flat, and then the patient's affected limb located on the top of the infusion table 11 is also lifted to a height higher than the patient's heart. Lifting the affected limb can use gravity to promote the blood and skin fluid in the extravasation site to return to the heart, which helps to reduce the accumulation of extravasated drugs in the local skin, thereby reducing blood vessel swelling caused by drug extravasation. At the same time, by promoting blood reflux to reduce swelling, pain can also be relieved accordingly, and the lifting of the affected limb can make the extravasated drugs flow toward the heart under the action of gravity, instead of continuing to diffuse to the surrounding skin. This helps to control the scope of drug extravasation and reduce damage to more skin.

[0058] When the trigger block 34 contacts the switch 35, the switch 35 controls the buzzer 36 through the external controller to sound an alarm. The alarm can attract the attention of medical staff as soon as drug extravasation occurs, so that the medical staff can deal with it in time. Compared with relying on the regular inspection of medical staff or the patient's own discovery of the problem and then calling, it can achieve the effect of timely reminder and avoid aggravating the patient's condition due to delayed treatment.

[0059] See also Fig.10 and Fig.11 As shown, when the lifting alarm component is in operation, due to the suddenness of the incident, the lifted affected limb may cause the patient to panic and move around subconsciously. Since the patient is still in the injection stop stage where the needle has not been pulled out, the moving affected limb may cause harm to the patient. Therefore, four anti-tampering components are arranged at the four corners of the side wall of the infusion table 11. The anti-tampering components include a rotating shaft 41, which is fixedly connected to the side wall of the infusion table 11. An L-shaped rod 42 is rotatably connected to the surface of the rotating shaft 41, a rubber block 43 is fixedly connected to the L-shaped rod 42, a torsion spring 44 is fixedly connected between the L-shaped rod 42 and the rotating shaft 41, and a plurality of magnets 45 corresponding to the position of the L-shaped rod 42 are fixedly connected to both sides of the bottom plate 32.

[0060] Among them: the L-shaped rod 42 is set to be made of iron material, and its function is to be magnetically attracted to the magnet 45. In the initial state, due to the magnetic attraction between the L-shaped rod 42 and the magnet 45, the torsion spring 44 is in an elastic deformation state, and the side of the rubber block 43 away from the L-shaped rod 42 is set to an arc surface, which can better fit the two sides of the arm.

[0061] When the anti-tampering assembly is in use, the alarm assembly is in the process of being raised, and the telescopic end of the electric telescopic rod 31 is extended to lift the infusion table 11.

[0062] When the telescopic ends of the multiple electric telescopic rods 31 are extended, the infusion table 11 is lifted to a higher height, and then the infusion table 11 and the bottom plate 32 are separated from each other, and the rotating shaft 41 drives the L-shaped rod 42 to rise synchronously. As the telescopic ends of the electric telescopic rods 31 continue to extend, the L-shaped rod 42 is no longer magnetically attracted to the magnet 45. At this time, under the elastic reset action of the torsion spring 44, the torsion spring 44 drives the L-shaped rod 42 to rotate upward, so that the rubber block 43 rotates upward around the rotating shaft 41. In this process, the rubber block 43 contacts the side of the patient's arm. Since there are four anti-tampering components, and at this time the patient's elbow fossa is located in the middle of the infusion table 11, that is, a part of the patient's upper arm and forearm are respectively placed flat on the infusion table 11, and then the four rubber blocks 43 are in a state of being flat. The rubber blocks 43 rotate in pairs and come into contact with the sides of the patient's upper arm and forearm. The curved surface of the rubber block 43 and the inward pressure applied to the L-shaped rod 42 by the torsion spring 44 make the rubber block 43 come into contact with the patient's affected limb and press against each other. The anti-slip surface of the rubber block 43 can enhance the friction between the rubber block 43 and the affected limb. At this time, the patient is lifted to a height higher than the heart, and the affected limb is fixed in place by the four rubber blocks 43. This avoids the patient panicking and causing the affected limb to move around during the lifting process, thereby ensuring the safety of the patient's affected limb during the lifting process. After the infusion table 11 is lowered, the L-shaped rod 42 can be manually rotated downward to be reset and re-adsorbed by the magnet 45.

[0063] At the same time, the four rubber blocks 43 fix the affected limb. During the lifting process of the affected limb, it can be ensured that the affected limb is lifted horizontally in accordance with the infusion table 11, so that the patient's blood vessels are in a more natural state, avoiding the blood vessels from tilting or twisting due to the patient's movement and affecting the blood flow. At the same time, it can make all parts of the affected limb be evenly affected by gravity, thereby promoting blood return.

[0064] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
