Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to an adjustable nursing device for intravenous therapy. Background Art

[0002] Intravenous therapy nursing devices are a series of instruments used to assist intravenous therapy, ensure the safety and effectiveness of treatment, and promote the recovery of patients. The following are some common devices: vascular access devices, auxiliary devices, and nursing and fixation devices. The nursing and fixation devices include elastic stockings and elastic bandages. Elastic stockings promote venous return through the design of different pressure gradients from the ankle to the thigh, reducing swelling and discomfort caused by varicose veins; elastic bandages are usually used during the recovery period after varicose vein surgery to help reduce postoperative edema, pain, and bleeding, and promote wound healing.

[0003] Varicose veins refer to the venous tortuosity and dilation caused by factors such as blood stasis and weak venous walls. Lower extremity varicose veins are a type of varicose veins. The early symptoms are not obvious and are easily overlooked. If left untreated for a long time, the disease will worsen. Since the elderly have relatively weak immunity in the population, the incidence of lower extremity varicose veins in the elderly is higher. Varicose veins themselves can cause poor blood return in the limbs. Coupled with increasing age, the disease develops more rapidly and is likely to develop into more harmful venous inflammation and ulcers. Preventing lower extremity varicose veins in the elderly can not only relieve the pain of lower extremity varicose veins but also effectively avoid the occurrence of the disease. Foot bathing can accelerate blood circulation in the legs, enabling the venous blood in the legs to return to the right heart in a timely manner, which is beneficial to reducing venous congestion in the legs and preventing and treating lower extremity varicose veins. Massaging the soles of the feet also has the effect of promoting blood circulation and activating meridians, which is beneficial to preventing lower extremity varicose veins. Rubbing the calf can more directly accelerate blood circulation in the legs.

[0004] Combined with actual work, we found that most of the existing lower extremity varicose vein nursing devices are elastic cylinder stockings (such as the high-elastic stockings for treating lower extremity varicose veins disclosed in the utility model patent with the publication number CN204468435U), which achieve varicose vein nursing by compressing the veins. However, such devices are troublesome to wear, the temperature cannot be adjusted, and the nursing effect is not significant. The elasticity or pressing force is not easy to adjust and control, and excessive elasticity or pressing force will cause discomfort in the patient's calves. Summary of the Invention

[0005] In order to improve the nursing effect on the legs of varicose vein patients, this application provides an adjustable nursing device for intravenous therapy.

[0006] An adjustable nursing device for intravenous therapy provided by this application adopts the following technical solutions:

[0007] An adjustable nursing device for intravenous therapy, comprising a base, a placement plate arranged on the base and used for placing the patient's leg, and a massage device installed on the placement plate. Both the base and the placement plate are long strip-shaped plate structures and are arranged along the length direction of the leg. The massage device includes a pair of massage plates that are slidably matched on the placement plate and massage the leg. The two massage plates are symmetrically arranged on both sides of the placement plate, and both massage plates are arc-shaped structures that cooperate with the leg, and the two massage plates can wrap around the patient's leg.

[0008] By adopting the above technical solution, when nursing varicose veins in the patient's leg, the patient's leg can be moved onto the placement plate, and the two massage plates are used to wrap around the patient's leg to form clamping and fixation. Through the two slidably matched massage plates, the patient controls the sliding of the massage plates to let the massage plates massage the leg, thereby realizing the nursing of the patient's leg and relieving the varicose veins on the patient's leg.

[0009] Preferably, the massage device further includes a driving component installed on the placement plate and used to control the movement of the two massage plates. The driving component includes a sliding block slidably matched on the placement plate and a driving member for driving the sliding block to move. The ends of the two massage plates are connected to the sliding block. The driving member includes a driving screw rod rotatably matched on the placement plate. The driving screw rod is arranged along the length direction of the placement plate, and the driving screw rod passes through the sliding block and is threadedly connected.

[0010] By adopting the above technical solution, when controlling the two massage plates to move and massage along the patient's leg, the provided sliding block can move along the placement plate, and the rotation of the driving screw rod can control the movement of the sliding block, thereby driving the two massage plates to move. During massage, the patient can directly control the rotation of the driving screw rod, avoiding the need to control the sliding of the two massage plates on the placement plate.

[0011] Preferably, the driving member further includes a driving motor arranged at one end of the placement plate. The output shaft of the driving motor is fixed to the end of the driving screw rod, and the driving motor controls the forward and reverse rotation of the driving screw rod.

[0012] By adopting the above technical solution, when controlling the rotation of the driving screw rod, the driving motor can directly drive the rotation of the driving screw rod, liberating the patient's hands, enabling the massage plates to massage the leg for a long time, and improving the nursing ability for varicose veins on the leg.

[0013] Preferably, the massage plate is hinged to the sliding block, and the two massage plates can rotate outward to open and rotate inward to close. The end of the massage plate close to the sliding block is fixedly provided with a rotating shaft, and the rotating shaft rotates on the sliding block. A torsion spring for automatically rotating the massage plate is sleeved on the rotating shaft. One end of the torsion spring is fixed to the massage plate, and the other end is fixed to the sliding block.

[0014] By adopting the above technical solution, the rotation shaft is arranged to enable the two massage plates to rotate freely on the sliding block. After the patient's leg needs to be moved onto the placement plate, the two massage plates are controlled to open outwards so that the patient's leg can be better moved onto the placement plate. After the leg is moved onto the placement plate, the two massage plates are then controlled to rotate outwards and close, enabling the massage plates to tighten around the patient's leg and form a wrap. Under the action of the torsion springs provided, the two massage plates can be in a closed state in the initial state. When massage is required, the two massage plates are opened. After the two massage plates clamp the patient's leg, the torsion springs provided can make the two massage plates always hold tightly to the patient's leg, preventing the two massage plates from opening outwards during massage.

[0015] Preferably, a plurality of massage rollers are rotatably arranged on the arc-shaped inner surface of the massage plate, and the plurality of massage rollers are evenly arranged along the arc direction of the massage plate, and the massage rollers can roll-press the leg.

[0016] By adopting the above technical solution, during the massage process, the massage rollers can abut against the leg, and by rolling the massage rollers along the patient's leg, the massage effect is achieved. The rolling massage can improve the nursing effect on the patient's varicose veins.

[0017] Preferably, a positioning plate is vertically fixed at the end of the placement plate, and the patient's foot can abut against the positioning plate.

[0018] By adopting the above technical solution, when massaging the patient's leg, the patient can place the foot against the positioning plate, and the massage rollers can better roll-press at the position of the patient's varicose veins, preventing the wrong placement position of the patient's leg on the placement plate and ensuring that the massage rollers cannot massage the correct position.

[0019] Preferably, a guiding hole is formed on the placement plate along its length direction, and the guiding hole runs through the placement plate along its width direction. The sliding block is slidably fitted in the guiding hole and extends out from both ends of the guiding hole. A pair of limiting plates are fixed at both ends of the sliding block, and the two limiting plates are snap-fitted to both sides of the placement plate.

[0020] By adopting the above technical solution, the sliding block can be slidably fitted into the guiding hole and move along the length direction of the guiding hole, thereby controlling the two massage plates to move and massage along the patient's leg. The limiting plates fixed at both ends of the sliding block can make the two limiting plates be snap-fitted to both side edges of the placement plate, making the sliding block more stable during the sliding process on the placement plate. In addition, the sliding block arranged in the guiding hole can make the surface of the placement plate smoother and flatter, enabling the patient's leg to be better placed on the placement plate and preventing the sliding block from rubbing against the patient's leg.

[0021] Preferably, the massage device further includes a flexible massage component installed on the placement board. The flexible massage component includes a pair of massage airbags installed on the placement board. The massage airbags are arranged along the length direction of the placement board, and the massage airbags are arc-shaped structures. The two massage airbags can wrap around the patient's legs. The air inlets of the two massage airbags are connected to the ports on both sides of the guiding holes. And a massage board is arranged inside the massage airbags. At the end of the placement board, there is a gas supply device for inflating and deflating the massage airbags, and the gas supply device communicates with the guiding holes.

[0022] By adopting the above technical solution, when massaging and nursing the patient's legs, the gas supply device can inflate the inside of the massage airbags, causing the massage airbags to expand. The expanded massage airbags can wrap around the patient's legs and squeeze and massage the legs.

[0023] Preferably, the massage device includes a pair of massage blocks rotatably arranged at both ends of the sliding block. The massage blocks are hollow structures inside. On the opposite surfaces of the two massage blocks, there are multiple massage rods slidably fitted. The massage rods are vertically arranged on the massage blocks and slidably penetrate through the massage blocks. The multiple massage rods are evenly arranged on the massage blocks, and each massage rod can freely stretch. A massage ball is fixed to the end of the massage rod facing the leg, and the massage ball abuts against the patient's leg. A fixing strap that is convenient for connection and disassembly is connected between the two massage blocks, and the two fixing straps are used to tighten the two massage blocks.

[0024] By adopting the above technical solution, when massaging the patient's legs, rotate the two massage blocks so that the two massage blocks rotate to both sides of the legs. After rotation, the massage blocks can make the massage balls at the ends of the massage rods abut against the leg skin. Due to the shape of the legs, each massage rod extends different lengths from the massage block to ensure that each massage ball can abut against the patient's leg. After the massage balls abut, fix the two massage blocks with the fixing strap, and finally control the movement of the sliding block so that the massage balls can roll on the surface of the patient's leg, thereby performing regular massage.

[0025] Preferably, a compression spring is sleeved on the massage rod inside the massage block. One end of the compression spring is fixed to the massage rod, and the other end is fixed to the inner wall of the massage block.

[0026] By adopting the above technical solution, when the massage rod abuts against the leg surface, the compression spring is compressed and applies an elastic force to keep the massage ball always abutting against the leg skin.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. In an open - wearing manner, the leg can be directly placed in the corresponding position, which is quite convenient for wearing. When massaging and nursing the patient's leg, the inflated massage airbag can tightly wrap the patient's leg, achieving extrusion of the patient's leg to relieve the pain caused by varicose veins in the patient's leg. Additionally, different degrees of massage effects can be achieved through intermittent inflation and deflation, thereby realizing the adjustment and control of the massage intensity. At the same time, intermittent massage is also realized, avoiding pain or other discomfort caused by massaging a certain fixed position for a long time;

[0029] 2. After the massage airbag expands, start the driving motor to drive the movement of the sliding block, enabling the massage plate to move inside the massage airbag along the leg. Thus, the massage roller can press against the leg through the massage airbag and roll along the leg. The reciprocally rolling massage roller can achieve a deep - level massage effect and can massage and care for all positions of the leg, with a larger range of massage and care;

[0030] 3. Through the massage method of the massage blocks and massage rods, during massage and nursing, the massage balls on each massage rod can be pressed tightly against the patient's leg skin, achieving a pricking - like massage effect. During the process of controlling the movement of the sliding block, the massage balls can roll on the leg skin, enabling the massage balls to perform regular massage on the leg, further realizing the original intention of this application design and achieving the expected technical effects of the research and development.

Detailed implementation manners

[0039] The following further elaborates on this application in conjunction with the Figure 1-7 accompanying drawings.

[0040] The embodiment of this application discloses an adjustable nursing device for intravenous therapy.

[0041] Embodiment 1

[0042] Referring to Figure 1 , an adjustable nursing device for intravenous therapy includes a horizontally arranged base 1 and a placing plate 2 fixed on the base 1. Both the base 1 and the placing plate 2 are long strip-shaped plate structures, and their length directions are the same. A massage device 3 for massaging the legs is installed on the placing plate 2. This nursing device can be used in pairs, aiming at the varicose veins of the patient's legs. When a varicose vein patient uses this nursing device, the legs can be placed on the placing plate 2, and then massaged by the massage device 3 to relieve the varicose veins of the legs. When using, the patient can use it lying flat or sitting.

[0043] Referring to Figure 1 and Figure 2, the massage device 3 includes a pair of massage plates 31 slidably arranged on the placement plate 2 and a driving assembly 32 for driving the sliding of the massage plates 31. The two massage plates 31 are symmetrically arranged on both sides of the placement plate 2. The massage plates 31 are of an arc-shaped structure, and the concave surfaces of the two massage plates 31 face each other. During massage, the two massage plates 31 can wrap around the patient's legs, and the legs are massaged by the sliding massage plates 31; a plurality of massage rollers 311 are rotatably arranged on the opposite concave surfaces of the two massage plates 31. The plurality of massage rollers 311 are evenly arranged along the arc direction of the massage plate 31. The plurality of massage rollers 311 form a group on the massage plate 31, and multiple groups of massage rollers 311 can be arranged on a single massage plate 31. The multiple groups of massage rollers 311 are arranged in a staggered manner along the width direction of the massage plate 31, so that the next group of massage rollers 311 is arranged at the position between two adjacent massage rollers 311 of the previous group. Therefore, during the massage process, the massage rollers 311 can press tightly against the legs, and the legs are rolled by the massage rollers 311 along the patient's legs to achieve the massage effect. Moreover, two or more groups of massage rollers 311 arranged can roll and cover all the skin of the legs, improving the nursing effect on the patient's varicose veins. Further, a positioning plate 21 is vertically fixed on the upper surface of the placement plate 2 and near one end thereof. During use, the patient can place the feet against the positioning plate 21, and the massage rollers 311 can better roll at the position of the patient's varicose veins, preventing the wrong placement position of the patient's legs on the placement plate 2 and ensuring that the massage rollers 311 cannot massage to the correct position.

[0044] Refer to Figure 2 and Figure 3, the driving assembly 32 includes a sliding block 321 slidably fitted on the placing plate 2 and a driving member for driving the sliding block 321 to slide. The length direction of the sliding block 321 is arranged along the width direction of the placing plate 2. Two massage plates 31 are symmetrically arranged at both ends of the sliding block 321, and the lower end of the massage plate 31 is connected to the end of the sliding block 321. The driving member includes a driving screw 322 rotatably arranged on the placing plate 2 and a driving motor 323 fixed on the base 1 and located at one end of the placing plate 2. The length direction of the driving screw 322 is arranged along the length direction of the placing plate 2, and both ends of the driving screw 322 are rotatably connected to both ends of the placing plate 2. The driving screw 322 horizontally passes through the sliding block 321 and is threadedly connected thereto. One end of the driving screw 322 passes through the placing plate 2. The output shaft of the driving motor 323 is fixed to the end of the driving screw 322. By driving the driving motor 323 to drive the rotation of the driving screw 322, the driving motor 323 can rotate forward and backward. When the driving motor 323 is started, it controls the massage plate 31 and the massage roller 311 to perform rolling massage on the leg. When the sliding block 321 moves to the end of the placing plate 2, the driving motor 323 reverses to control the movement of the sliding block 321. Through the reciprocating movement of the sliding block 321 on the placing plate 2, the massage plate 31 and the massage roller 311 perform continuous rolling massage on the patient's leg, improving the effect of nursing the legs of patients with varicose veins.

[0045] Refer to Figure 1 and Figure 3 , a guiding hole 22 is formed in the placing plate 2. The length direction of the guiding hole 22 is arranged along the length direction of the placing plate 2, and the width direction of the guiding hole 22 penetrates through the width direction of the placing plate 2. The sliding block 321 is slidably fitted in the guiding hole 22, and both ends of the sliding block 321 extend out of the guiding hole 22. A pair of limiting plates 324 are symmetrically fixed at both ends of the sliding block 321 outside the guiding hole 22. The two limiting plates 324 are snap-fitted to both side edges of the placing plate 2, making the sliding of the sliding block 321 on the placing plate 2 more stable. In addition, the sliding block 321 arranged in the guiding hole 22 can make the surface of the placing plate 2 smoother and flatter, enabling the patient's leg to be better placed on the placing plate 2 and avoiding being affected by the sliding of the sliding block 321.

[0046] Refer to Figure 2 and Figure 3, the end of the massage plate 31 and the end of the sliding block 321 are hinged, enabling the two massage plates 31 to open outward and close inward relative to each other. A rotating shaft 312 is fixedly inserted through the end of the massage plate 31. A pair of ear plates 325 are fixed at the end of the sliding block 321. Both ends of the rotating shaft 312 are rotatably inserted through the two ear plates 325, and the rotating shaft 312 is hinged with the sliding block 321. The provided rotating shaft 312 allows the massage plate 31 to rotate more freely on the sliding block 321. A torsion spring 33 is sleeved on the rotating shaft 312. One end of the torsion spring 33 is fixed to the massage plate 31, and the other end is fixed to the sliding block 321. In the initial state, the two massage plates 31 are relatively closed under the action of the torsion spring 33 and are fastened to the patient's leg, so that the massage rollers 311 are always pressed against the leg surface. Since the thickness of the patient's leg varies from the foot upwards, the provided torsion spring 33 can make the two massage plates 31 always hold tightly to the patient's leg. When the patient moves the leg onto the placement plate 2, the patient manually rotates the two massage plates 31 outward, then places the leg on the placement plate 2. After placement, release the two massage plates 31 to clamp onto the leg. Additionally, the two massage plates 31 can be horizontally offset on the sliding block 321 so that the two massage plates 31 can be arranged crosswise with each other, preventing the ends of the two massage plates 31 away from the sliding block 321 from abutting against each other after moving to the patient's ankle, which would cause the massage plates 31 to be unable to hold tightly to the patient's leg.

[0047] Refer to Figure 1 and Figure 4, the massage device 3 further includes a flexible massage component 34 installed on the placement board 2. The flexible massage component 34 includes a pair of massage airbags 341 fixed on the placement board 2. The massage airbags 341 are arranged along the length direction of the placement board 2, and the air inlet of the massage airbag 341 is strip-shaped. The air inlet of the massage airbag 341 is fixed at the port of the guide hole 22, so that a closed structure is formed between the two massage airbags 341 and the guide hole 22. The massage airbag 341 is an arc-shaped structure, and the two massage airbags 341 can wrap around the patient's legs. The massage airbag 341 is made of a flexible and skin-friendly material; a gas supply device 342 is arranged on the base 1 and at a position at one end of the placement board 2. The gas supply device 342 is internally connected to the guide hole 22. The gas supply device 342 conveys gas into the guide hole 22 and fills it into the massage airbag 341, causing the massage airbag 341 to expand, and enabling the two massage airbags 341 to wrap around the patient's legs, forming a certain squeezing massage on varicose veins of the legs; the massage board 31 and the massage rollers 311 are both arranged inside the massage airbag 341. After the massage airbag 341 expands, the massage rollers 311 can be pressed tightly against the patient's leg skin, allowing the massage board 31 to move inside the massage airbag 341. During the nursing process of varicose veins, the massage airbag 341 forms a certain massage effect, and the moving massage board 31 and massage rollers 311 roll-press the legs again, realizing double massage care and improving the ability to care for varicose veins.

[0048] Refer to Figure 1 and Figure 4 , a plurality of sets of connecting buckles 343 are arranged between the two end parts of the massage airbag 341 away from the placement board 2. The plurality of sets of connecting buckles 343 are evenly arranged along the length direction of the massage airbag 341 in the reverse direction. The arranged connecting buckles 343 can connect and fix the end parts of the two massage airbags 341 away from the placement board 2. After the patient's leg moves onto the placement board 2 and the massage airbag 341 is inflated, the multiple connecting buckles 343 are connected and fixed, enabling the two massage airbags 341 to tightly wrap around the patient's legs, preventing the two ends of the massage airbag 341 from spreading during the massage process; flexible temperature control plates 344 are fixed on the concave surfaces of the two massage airbags 341. The temperature control plates 344 are connected to the power supply. During use, the temperature of the temperature control plates 344 can be adjusted as needed to heat or cool, so that the surface of the patient's legs can be at a suitable temperature, improving the nursing effect on the legs.

[0049] The implementation principle of Embodiment 1 is as follows: When performing massage care on the varicose veins of a patient's leg, the patient moves the leg onto the placement board 2, aligns the foot with the positioning board 21, then inflates the massage airbag 341 so that the massage airbag 341 can just wrap around the leg. After inflation is completed, the two massage airbags 341 are fixed with the connecting buckle 343. Then, the driving motor 323 is started, enabling the massage board 31 to move inside the massage airbag 341, so that multiple massage rollers 311 perform rolling massage on the patient's leg. During the massage process, the temperature control board 344 can be adjusted to an appropriate temperature to heat or cool the patient's leg skin, improving the care effect on leg varicose veins and relieving discomfort such as pain caused by varicose veins.

[0050] Embodiment 2

[0051] Referring to Figure 5 and Figure 6 This embodiment is different from Embodiment 1 in that the massage structure for massaging the patient's leg is different. In this embodiment, the massage device 3 includes a pair of massage blocks 35 hinged to both ends of the sliding block 321. The massage blocks 35 have a hollow internal structure. When massaging the leg, the two massage blocks 35 rotate into a vertical state. A plurality of massage rods 351 are vertically penetrated through the massage blocks 35. The massage rods 351 are arranged densely and evenly on the massage blocks 35. Each massage rod 351 is slidably arranged on the massage block 35, enabling the sliding massage rods 351 to freely stretch and abut against the leg skin. During massage care, the plurality of massage rods 351 can conform to the shape of the patient's leg so that the ends of the massage rods 351 all abut against the leg, and the plurality of massage rods 351 on the two massage blocks 35 form a wrapped and tightened state against the leg. A massage ball 352 is hinged to the end of each massage rod 351 facing the leg, enabling the massage ball 352 to abut tightly against the patient's leg. When performing massage care on the patient's leg, by controlling the movement of the sliding block 321, the massage ball 352 can roll on the surface of the patient's leg, thereby performing regular massage.

[0052] Referring to Figure 5 and Figure 7A fixing belt 353 is provided between the two ends of the two massage blocks 35 away from the sliding block 321, and the fixing belt 353 can connect and fix the two massage blocks 35. When it is necessary to massage the legs, the two massage blocks 35 are wrapped around the legs, and then the two massage blocks 35 are fixed by the fixing belt 353 to prevent the two massage blocks 35 from rotating during the massage process, so that the massage balls 352 are out of contact with the legs; a compression spring 354 is sleeved on each massage rod 351 inside the massage block 35, one end of the compression spring 354 is fixed to the massage rod 351, and the other end is fixed to the inner wall of the massage block 35. In the initial state, the compression spring 354 can allow the massage rod 351 to extend the longest distance on the massage block 35. When the massage rod 351 is pressed against the surface of the leg, the compression spring 354 is compressed and exerts elastic force to keep the massage ball 352 pressed against the leg skin. A temperature regulating plate 355 is fixed on the surfaces of the two massage blocks 35 that are away from each other. The massage rod 351 passes through the temperature regulating plate 355. The massage rod 351 and the massage ball 352 are both made of heatable materials. The temperature regulation of the temperature regulating plate 355 can regulate the temperature of the massage rod 351, thereby transferring the temperature to the leg skin through the massage ball 352. While massaging, the surface of the patient's legs is heated to improve the care effect.

[0053] The implementation principle of Example 2 is as follows: when massaging the patient's varicose veins on the legs, rotate the two massage blocks 35 so that the massage balls 352 can be pressed against the legs, and then fix the two massage blocks 35 through the fixing belts 353 so that the two massage blocks 35 can be clamped to the patient's legs, so that the massage balls 352 on each massage stick 351 can be pressed against the leg skin, and finally control the movement of the sliding block 321 to allow the massage balls 352 to roll and massage the surface of the legs to achieve the effect of massage care.
