Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to a neurointerventional pressurized nursing device. Background Art

[0002] Neurointerventional pressurized flushing refers to the process during neurointerventional surgery in which a certain pressure is applied to the flushing fluid through a specific device to make it flow rapidly in the blood vessels and interventional instrument channels, thereby removing substances such as drug solutions, thrombus fragments, tissue debris, maintaining a clear surgical field of view, preventing catheter and guidewire blockage, and maintaining vascular patency.

[0003] The traditional pressurization method is to put a pressure bag on the outside of the infusion bag. Medical staff inflate the spherical air bag by holding it in their hands, and expand the air bag through the air tube to squeeze the infusion bag. This method requires nurses to frequently enter the catheterization room to press the spherical air bag, which is inconvenient to operate. Moreover, only one infusion bag can be pressurized at a time. It relies on the operator's experience, and the pressure control is imprecise, which can easily lead to air embolism, hypothermia complications, etc.

[0004] The existing infusion bag pressurizing device is more accurate in controlling the pressurization by setting a pressure gauge, but there are still some problems with the part in contact with the infusion bag. On the one hand, when a conventional air bag is inflated with gas, the middle part bulges the most, and the middle part of the infusion bag is squeezed the most. The air bag may squeeze part of the liquid above the middle part of the infusion bag upward, causing the liquid above the infusion bag to be difficult to flow downward, affecting the infusion speed. On the other hand, the existing pressurizing device lacks an alarm device and cannot remind medical staff to replace the infusion bag in time. As the liquid in the infusion tube drips away, air will enter the intracranial blood vessels through the interventional tube, leading to the formation of air embolism, which can be fatal in severe cases.

The drawings described in the present invention are only structural schematic diagrams.

[0024] The present invention provides a neurointerventional compression nursing device, such as Figures 1 to 3 As shown, it includes a pressurizing component 1 for pressurizing the infusion bag, and the pressurizing component 1 includes a pair of extrusion plates 101, a groove 102 is opened in the middle of the pair of extrusion plates 101, the pair of extrusion plates 101 are located on the left and right sides of the infusion bag and are connected to the bracket 2 for hanging the infusion bag, and a movable plate 103 is correspondingly provided on the pair of extrusion plates 101. The movable plate 103 is vertically arranged in the groove 102 and is slidably connected to the extrusion plate 101 along the opening direction of the groove 102. The movable plate 103 is provided with an arc-shaped abutting surface 105 adapted to the infusion bag on the side facing the infusion bag. A pressurizing airbag 104 is provided in the pair of movable plates 103, and the pair of pressurizing airbags 104 are arranged one by one correspondingly to the pair of movable plates 103. The pressurized airbag 104 is located in the groove 102, and the pressurized airbag 104 is set in a bellows shape. A placement groove is opened on the extrusion plate 101, and the pressurized airbag 104 is located in the placement groove. A moving rod 106 is provided in the placement groove. One end of the moving rod 106 is fixedly connected to the telescopic end of the pressurized airbag 104, and the other end is fixedly connected to the moving plate 103. The inflation component 4 includes a first inflation tube 41 and a pressurizing instrument 42. One end of the first inflation tube 41 is connected to the air outlet of the pressurizing instrument 42, and the other end is connected to the air inlet of the pressurized airbag 104. Medical rubber is provided on the arc-shaped abutting surface 105. The alarm device is provided on the bracket 2. When the liquid medicine in the infusion bag is delivered, it will promptly remind medical staff to replace it.

[0025] When in use, the infusion bag is placed between a pair of extrusion plates 101, and the pressurizer 42 delivers gas to the airbag through the first inflation tube 41. Because the airbag is located in the placement groove, the movable rod 106 is pushed when the airbag expands. At this time, the movable rod 106 pushes the movable plate 103, and the movable plate 103 slides with the extrusion plate 101 and moves stably toward one side of the infusion bag. The infusion bag is squeezed in both directions by the movable plates 103 on both sides of the infusion bag, so that the pressure of the infusion bag is balanced, and the uneven pressure does not affect the flow of the part of the medicine in the infusion bag and affects the infusion situation. Moreover, the movable plate 103 is provided with an arc-shaped abutting surface 105 close to the infusion bag side to better fit the side of the infusion bag, so that the pressure on the infusion bag is balanced, which is convenient for the infusion pressurization work.

[0026] Preferably, Figure 1 As shown, the bracket 2 includes a base 21, a telescopic rod group 22, a support plate 23, a support rod 24 and a hook. The bottom end of the telescopic rod group 22 is fixedly connected to the base 21, and the top end is fixedly connected to the support plate 23. A plurality of support rods 24 are evenly arranged around the support plate 23. The bottom side of the support rod 24 is fixedly connected to a hook for hanging an infusion bag. The telescopic rod group 22 includes a first telescopic rod 221 and a second telescopic rod 222. The first telescopic rod 221 is vertically fixedly connected to the top of the base 21, and the second telescopic rod 222 is slidably inserted in the first telescopic rod 221. A plurality of through-limiting holes are evenly and horizontally opened on the first telescopic rod 221 and the second telescopic rod 222 along the axial direction. A limiting screw 223 is inserted into any one of the through-limiting holes. The limiting screw 223 sequentially penetrates the first telescopic rod 221 and the second telescopic rod 222. A limiting nut is adapted on the limiting screw 223, and the pressurizer 42 is fixedly connected to the second telescopic rod 222.

[0027] In this embodiment, the base 21 supports the first telescopic rod 221. When in use, the second telescopic rod 222 is stretched to an appropriate height. After the limiting screw 223 passes through the first telescopic rod 221 and the second telescopic rod 222 in sequence, the nut is screwed on the limiting screw 223 to limit the relative position of the first telescopic rod 221 and the second telescopic rod 222, thereby improving the overall applicability of the device. The second telescopic rod 222 supports the support plate 23, and a number of support rods 24 are evenly arranged around the support plate 23. Each support rod 24 is provided with a pressure component 1 to facilitate application in various complex situations.

[0028] Preferably, Figures 1 and 2As shown, a reset assembly 3 is provided between a pair of extrusion plates 101. The reset assembly 3 includes a placement tube 31 and a first spring 32. A pair of placement tubes 31 are provided. The pair of placement tubes 31 are correspondingly provided with a pair of extrusion plates 101. The pair of placement tubes 31 are both horizontally slidably inserted on the support rod 24. The first spring 32 is sleeved on the placement tube 31, one end of which is fixedly connected to the support rod 24, and the other end is fixedly connected to the extrusion plate 101.

[0029] In this embodiment, a reset component 3 is provided between a pair of extrusion plates 101. Since the infusion bag may shake under pressure when the pressurizing component 1 is working, a placement tube 31 and a first spring 32 are provided in this embodiment. When the infusion tube is hung on the hook, the pair of extrusion plates 101 are first pulled to pull a portion of the placement tube 31 out of the support rod 24. At this time, the first spring 32 is in a stretched state. After the infusion bag is hung on the hook, the stretched extrusion plate 101 is released. At this time, the stretched first spring 32 needs to return to its original position and will pull the pair of extrusion plates 101. The pair of extrusion plates 101 will clamp the infusion bag and limit it to prevent the infusion bag from shaking during pressurization, resulting in uneven pressure on the infusion bag.

[0030] Preferably, Figures 1 to 3 As shown, the inflation component 4 also includes a second inflation tube 43 and a third inflation tube 44, the pressure gauge 42 is fixedly connected to one side of the telescopic rod group 22, the telescopic rod group 22 is hollow inside, the first inflation tube 41 is located in the telescopic rod group 22, and the support plate 23 and the support rod 24 are both provided with channels, the first inflation tube 41 is located in the channel, the second inflation tube 43 and the third inflation tube 44 are both configured as elastic tubes, the second inflation tube 43 and the third inflation tube 44 are respectively located on both sides of the support rod 24, and are connected to the corresponding pressurized airbag 104 air inlet, the second inflation tube 43 and the third inflation tube 44 are respectively placed in the placement tube 31 on each side.

[0031] In this embodiment, the first inflation tube 41 is directly arranged in the hollow second telescopic tube 63 to avoid being arranged outside and causing the first inflation tubes 41 to be entangled with each other, which affects the pressurization work. Since the extrusion plate 101 needs to be adjusted back and forth, the second inflation tube 43 and the third inflation tube 44 are both elastic tubes, which can better transport the gas of the pressurizer 42 to the pressurized airbag 104 and maintain the stable expansion of the pressurized airbag 104.

[0032] Preferably, Figures 4 and 5As shown, a support tube 5 is fixedly sleeved on the second telescopic rod 222, and the support tube 5 is axially and evenly fixedly connected with several limit assemblies 6. The limit assembly 6 includes a concave support block 61, a clamping plate 62, a telescopic tube 63 and a second spring 64. The concave block is fixedly connected to the second telescopic rod 222, and a pair of clamping plates 62 are provided. A pair of clamping plates 62 are arranged opposite to each other and are fixedly connected to the telescopic tube 63 on one side away from each other. One end of the telescopic tube 63 is fixedly connected to the concave support block 61, and the second spring 64 is sleeved on the telescopic tube 63, one end is fixedly connected to the clamping plate 62, and the other end is fixedly connected to the concave support block 61. A cavity is provided in the support tube 5, and the support tube 5 is made of heat-conducting material. A heater 7 is provided in the cavity. A cavity is provided in the base 21, and a water inlet is provided on the top of the base 21, and a drain outlet is provided on the side. Plugs are inserted on the water inlet and the drain outlet.

[0033] In this embodiment, when performing infusion, in order to avoid the impact caused by the messy placement of the infusion tube, a limiting component 6 is designed to limit the infusion tube, and the adjusting part of the infusion tube is placed between a pair of clamping plates 62. In the original state, the pair of clamping plates 62 are tightly attached. The pair of clamping plates 62 will stably clamp the adjusting part of the infusion tube to limit the infusion tube. In addition, a cavity is provided inside the support tube 5 provided in this embodiment, and a heater 7 is provided inside to heat the support tube 5. The support tube 5 will heat the liquid medicine passing through the clamping plate 62 to improve the comfort of the patient during use. A cavity is provided in the base 21. When in use, water is injected into the base 21 through the water inlet to improve the stability of the base 21. When the use is completed and the water is stored, it is discharged through the drain outlet.

[0034] Preferably, Figure 1 As shown, the alarm device includes a pair of squeezing plates 101, each of which is close to another side and is provided with a pressure sensor 8 and a pressure rod 9. An alarm 10 is provided on the base 21. The pressure sensor 8 and the alarm 10 are electrically connected. When the liquid in the infusion bag is squeezed, the pressure rod 9 touches the pressure sensor 8, and the pressure sensor 8 will control the alarm 10 to alarm.

[0035] In this embodiment, as the infusion work proceeds, a pair of extrusion plates 101 will approach each other. When the infusion of the liquid in the infusion bag is completed, the pressure rod 9 will touch the pressure sensor 8. At this time, the pressure sensor 8 will transmit the information to the signal receiver in the alarm 10. After receiving the signal, the signal receiver will make the alarm 10 sound an alarm through the control part, and promptly remind medical staff to replace the infusion bag.

[0036] The method of using the neurointerventional compression nursing device of the present invention is as follows:

[0037] Move the base 21 to the side of the patient's bed, and add water into the base 21 through the water inlet to improve the stability of the base 21. At this time, stretch the second telescopic rod 222 to a suitable height, insert the limit bolts through the first telescopic rod 221 and the second telescopic rod 222 in sequence, and then screw the nuts on the bolts to limit the relative positions of the first telescopic rod 221 and the second telescopic rod 222.

[0038] Pull a pair of extrusion plates 101 to pull a portion of the placement tube 31 out of the support rod 24. At this time, the first spring 32 is in a stretched state. After hanging the infusion bag on the hook, release the stretched extrusion plate 101. At this time, the stretched first spring 32 needs to return to its original position and will pull the pair of extrusion plates 101. The pair of extrusion plates 101 will clamp the infusion bag and limit it to prevent the infusion bag from shaking during pressurization, resulting in uneven pressure on the infusion bag.

[0039] The pressurizing instrument 42 rushes the gas into the pressurized airbag 104 through the first inflation tube 41, the second inflation tube 43 and the third inflation tube 44. At this time, because the airbag is located in the placement groove, it will push the set moving rod 106 when the airbag expands. At this time, the moving rod 106 will push the set moving plate 103. The moving plate 103 slides with the extrusion plate 101 and will move stably toward one side of the infusion bag. The infusion bag is squeezed by the two-way movement of the moving plates 103 located on both sides of the infusion bag, so that the pressure on the infusion bag is balanced, and.

[0040] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
