Description

Technical Field

[0001] The invention relates to the technical field of catheter treatment nursing devices, in particular to a catheter nursing device for intravenous treatment in an oncology department. Background Art

[0002] Central venous catheterization via peripheral venous puncture is to puncture the vein of the peripheral arm with a catheter. After puncture, the dressing at the puncture site needs to be changed and disinfected every day. When changing the dressing at the puncture site, it is necessary to avoid pulling out the catheter.

[0003] When medical staff are cleaning the catheter and the patient's puncture point, the catheter remaining on the patient after puncture does not have a structure for auxiliary care. This causes subsequent staff to swing their arms and pull the catheter. At the same time, due to the differences in physique and arms of each patient, some patients' arms are not suitable for lying flat. On the other hand, there are many catheters required for later infusion, but there are no separate devices to fix them, resulting in entanglement of multiple catheters, thus affecting later care.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0026] like Figure 1-7 As shown, the present invention provides a catheter care device for intravenous treatment in the oncology department, including a base plate 1, a U-shaped positioning frame 11 is slidably provided on the lower surface of the base plate 1, a positioning component is provided in the positioning frame 11, a vertically arranged fixing column 4 is fixedly provided at the middle end of the upper surface of the base plate 1, a care plate 12 is rotatably provided on the top of the fixing column 4, a groove 2 is provided at one end of the upper surface of the fixing plate, a first adjustment block and a second adjustment block are slidably provided at the two ends inside the groove 2, a support plate 13 is provided on the top of the first adjustment block and the second adjustment block, a fixing sleeve 14 is fixedly provided on the upper surface of the support plate 13, an observation groove 15 is provided at the middle end of the fixing sleeve 14, and circular airbag cushions 16 are installed inside the two ends of the fixing sleeve 14.

[0027] The fixing assembly includes a positioning frame 11, and positioning plates 6 are arranged inside the two ends of the positioning frame 11. Two symmetrically arranged adjusting screws 61 are threadedly inserted at the bottom of the positioning frame 11, and the tops of the adjusting screws 61 are connected to the positioning plate 6 through bearings.

[0028] By adopting the above technical solution, the staff rotates the two adjusting screws 61 towards each other at the same time, and jointly pushes the top positioning plate 6 to move, thereby cooperating with the top of the positioning frame 11 so that the device is stably fixed as a whole at the edge of the patient's bed, which is convenient for timely installation and subsequent rapid disassembly.

[0029] The internal rotation of the nursing plate 12 is provided with two symmetrically arranged first screw rods 21 and second screw rods 22, the threads on the two first screw rods 21 and second screw rods 22 are respectively opened at both ends and are arranged diagonally, the threads between the two first screw rods 21 and second screw rods 22 located in the groove 2 are arranged oppositely, the first slider 23 and the second slider 24 are respectively threadedly inserted on the first slider 23 and the second slider 24, an adjusting rod 25 is hingedly provided between the upper surfaces of the first slider 23 and the second slider 24 and the lower surface of the support plate 13, and the adjusting rod 25 between the first slider 23 and the second slider 24 is arranged in an "eight" shape.

[0030] By adopting the above technical solution, the first slider 23 and the second slider 24 can be driven to move respectively by the first screw rod 21 and the second screw rod 22. Later, when only the first slider 23 moves, the adjustment rod 25 hinged to the first slider 23 and the support plate 13 will change its angle, so that one end of the support plate 13 is tilted downward or upward. When the first screw rod 21 and the second screw rod 22 are driven to rotate at the same time, the two adjustment rods 25 can be controlled to work synchronously at the same time, so that the overall vertical height of the fixed sleeve 14 on the support plate 13 can be adjusted, which can better meet the needs of patients from different user groups.

[0031] A horizontally arranged mounting plate 3 is fixedly connected to one end of the side wall of the support plate 13 near the fixed column 4, and an inverted U-shaped fixing frame 31 is fixed on the mounting plate 3. An arc-shaped placement groove 32 is opened on the upper surface of the outer wall of the fixing frame 31, and semicircular supporting plates 33 are fixed at both ends of the placement groove 32. A limiting plate 34 is rotatably provided at one end of the upper surface of the fixing frame 31, and a flexible limiting cotton 35 is fixed on the end of the limiting plate 34 near the placement groove 32.

[0032] By adopting the above technical solution, a plurality of placement grooves 32 are provided to limit the different catheters required for subsequent infusion, so as to avoid the intersection and entanglement of multiple catheters. The catheter can be positioned close to the patient's arm through the limiting plate 34 and the supporting plate 33, which can solve the problem that the catheter arranged on the surface is not limited away from the arm.

[0033] A magnetic block 36 for attracting each other is fixedly disposed between the end of the limiting plate 34 away from the rotation of the limiting plate 34 and the top of the fixing frame 31 .

[0034] By adopting the above technical solution, the magnetic block 36 can ensure that the limiting plate 34 can be against the surface of the fixing frame 31, so that the separated catheters can be limited to avoid interlacing and causing subsequent confusion, which affects the use.

[0035] A long plate 44 is fixedly provided at one end of the nursing plate 12 away from the fixed sleeve 14, and a horizontal plate 41 vertically arranged therewith is fixedly provided on the upper surface of the bottom plate 1 directly below the long plate 44. A moving block 43 is slidably provided in the horizontal plate 41, and a rotating block 45 is rotatably provided on the lower surface of the long plate 44. The bottom of the rotating block 45 is movably inserted in the moving block 43, and a third screw rod 42 is rotatably provided inside the horizontal plate 41. The bottom thread of the moving block 43 is inserted on the third screw rod 42.

[0036] By adopting the above technical solution, the third screw rod 42 drives the moving block 43 to move. At this time, the moving block 43 will drive the long plate 44 on the top to move through the rotating block 45. The long plate 44 drives the nursing board 12 to rotate with the fixed column 4 as the center, so that the angle of the nursing board 12 itself can be adjusted. When some patients need to tilt their arms, they can be adjusted relatively to meet the patients' needs.

[0037] The ends of the first screw rod 21 , the second screw rod 22 , the third screw rod 42 and the adjusting screw rod 61 are all fixedly provided with driving wheels with anti-slip strips.

[0038] By adopting the above technical solution, the rotating wheel can be used to facilitate the staff to directly drive the first screw rod 21, the second screw rod 22, and the third screw rod 42 to rotate, thereby improving the convenience of operation.

[0039] Two symmetrically arranged slide plates 5 are fixedly provided on the top of the fixing frame 31, and the top of the slide plate 5 is movably inserted in the lower surface of the base plate 1, and a second connecting plate 57 is fixedly provided at the end of the base plate 1 away from the fixing sleeve 14, and a plurality of equally spaced stop grooves 56 are provided between the lower surface of the second connecting plate 57 and the lower surface of the base plate 1, and a first connecting plate 51 in a U-shape is commonly fixed between the lower surfaces of the two slide plates 5, and a vertically arranged stop rod 52 is movably inserted in the second connecting rod directly below the stop groove 56, and the top of the stop rod 52 is inserted in the stop groove 56, and a pull plate 55 is commonly fixed at the bottom of the two stop rods 52.

[0040] By adopting the above technical solution, the nursing staff can directly push the base plate 1 to move through the second connecting plate 57. At this time, the fixed sleeve 14 and other components located on the base plate 1 will move together, and the fixed sleeve 14 can be adjusted. In this way, when caring for different patients in the future, the distance between the patient's arm and the bedside can be adjusted to meet the usage conditions of different patients.

[0041] A stopper 53 is fixedly provided above the stopper rod 52 , and a spring 54 is fixedly connected between the lower surface of the stopper block 53 and the first connecting plate 51 , and the spring 54 is sleeved on the stopper rod 52 .

[0042] By adopting the above technical solution, the set block 53 can squeeze the spring 54. When the pull plate 55 is subsequently released, the spring 54 will push the block 53 to drive the stop rod 52 to be inserted into the stop groove 56 as a whole, thereby completing the fixation of the base plate 1. After adjusting the position distance of the base plate 1, it is ensured that it is prevented from moving during subsequent use by the patient, thereby preventing harm to the patient.

[0043] The second connecting plate 57 is configured in a U shape as a whole.

[0044] By adopting the above technical solution, the second connecting plate 57 is set to be U-shaped, which can facilitate subsequent staff to directly push the second connecting plate 57 to control the sliding plate 5 and other components to move horizontally, thereby controlling the distance between the bedside and the patient's arm to adjust and better meet the usage conditions of different patients.

[0045] Working principle: When in use, the staff can clamp the edge of the bed on the U-shaped positioning frame 11, and then the staff can directly rotate the two adjustment screws 61 towards each other at the same time to jointly push the top positioning plate 6 to move, so as to cooperate with the top of the positioning frame 11 so that the device is stably fixed on the edge of the patient's bed as a whole, which is convenient for timely installation and subsequent rapid disassembly;

[0046] Then the patient's arm can first pass through the fixing sleeve 14, so that the puncture position is left in the middle of the observation slot 15 to prevent the catheter from being compressed. At this time, the airbag cushion 16 is inflated, and the airbag cushion 16 can collide with the inner circle to limit the front and rear ends of the patient's puncture position, thereby ensuring that the patient's arm is not swinging and affecting the catheter position, causing damage to the patient's arm;

[0047] The staff can subsequently adjust the first screw rod 21 and the second screw rod 22 to rotate respectively, so that the first slider 23 and the second slider 24 can be driven to move respectively. When only the first slider 23 moves later, the adjustment rod 25 hinged to the support plate 13 of the first slider 23 will change the angle, so that one end of the support plate 13 is tilted downward or upward. When the first screw rod 21 and the second screw rod 22 are driven to rotate at the same time, the two adjustment rods 25 can be controlled to work synchronously at the same time, so that the vertical height of the entire fixed sleeve 14 on the support plate 13 can be adjusted, which can better meet the needs of patients of different user groups.

[0048] When different catheters need to be set for infusion later, the multiple placement slots 32 can limit the different catheters required for infusion later, so as to avoid the entanglement of multiple catheters caused by crossing each other, thereby affecting the subsequent care. The catheter can be positioned close to the patient's arm by the limiting plate 34 and the supporting plate 33. This can solve the problem that the catheter set on the surface is not limited away from the arm, resulting in the movement of the catheter in the subsequent use, which affects the patient's puncture position.

[0049] By driving the third screw rod 42 to rotate, the moving block 43 can be driven to move. At this time, the moving block 43 will drive the top long board 44 to move through the rotating block 45, and the long board 44 will drive the nursing board 12 to rotate with the fixed column 4 as the center, so that the angle of the nursing board 12 itself can be adjusted. When the arms of some patients need to be tilted, they can be adjusted relatively. When the positioning frame 11 is installed to the edge of the bed, the nursing staff can first directly push the base plate 1 to move through the second connecting plate 57. At this time, the fixed sleeve 14 and other components located on the base plate 1 will move together, and the fixed sleeve 14 can be adjusted. In this way, when caring for different patients in the future, the distance between the patient's arm and the bedside can be adjusted to meet the usage of different patients.

[0050] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
