Description

Technical Field

[0001] The utility model relates to the technical field of infusion stands, in particular to a mobile infusion device for emergency departments. Background Art

[0002] As one of the common medical equipment, the IV stand is common, but it does not mean that you can choose it at will, because it is the basic configuration to ensure the smooth infusion. When choosing an IV stand, you generally need to consider the load-bearing capacity, height adjustment and stability. The load-bearing capacity is the premise to ensure safe infusion, the height adjustment is to meet the needs of different patients, and the stability is to prevent the infusion bottle or bag from tipping over due to external collision.

[0003] In the prior art, the infusion stand utilizes the height difference to allow the liquid medicine to flow into the patient's body through the pipe. Therefore, in order to meet the needs of most people, the height of the infusion stand is made relatively high. This makes it more troublesome for medical staff with shorter height to replace the infusion bottle. The emergency department is under great pressure and has a fast work pace. The troublesome replacement of the infusion bottle will undoubtedly increase the pressure of the medical staff in the emergency room in disguised form. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide a mobile infusion device for emergency department, so as to solve the technical problems mentioned in the above background technology.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A mobile infusion device for emergency department comprises a chassis, a plurality of movable wheels are connected to the bottom of the chassis, a sleeve is fixedly connected to the top of the chassis, a piston is slidably connected inside the sleeve, a support spring is arranged between the bottom of the piston and the sleeve, a support rod extending out of the sleeve is fixedly connected to the top of the piston, and a hook for placing an infusion bottle is arranged at one end of the support rod away from the piston.

[0007] Furthermore, a circular groove is formed at the bottom of the piston, and the circular groove extends into the support rod. A plurality of exhaust holes connected to the circular groove are formed at the bottom of the outer wall of the support rod.

[0008] Furthermore, a sealing sheet is hingedly connected to the support rod above the exhaust hole, and a side of the sealing sheet close to the support rod is provided with a curved surface that fits with an outer side wall of the support rod.

[0009] Furthermore, the width of the sealing sheet is greater than the width of the exhaust hole, and the length of the sealing sheet is less than the length of the exhaust hole, so that when the sealing sheet is in contact with the support rod, a gap remains between the sealing sheet and the exhaust hole.

[0010] Furthermore, when the sealing sheet is in contact with the support rod, a gap is left between the sealing sheet and the inner wall of the sleeve.

[0011] Furthermore, a collar is fixedly connected to the top of the sleeve, and a placement table for placing medical instruments is fixedly connected to the outer side wall of the collar.

[0012] In summary, the present invention includes at least one of the following beneficial technical effects:

[0013] 1. The mobile infusion device for emergency department can easily adjust the height of the hook during use through the piston, support spring and support rod, so that medical staff can replace the infusion bottle more easily and save trouble, thereby reducing the work pressure of medical staff in the emergency room, reducing the physical burden of medical staff, and making the infusion device more practical;

[0014] 2. This mobile infusion device for emergency department can make it easier to move the hook down by setting the exhaust hole and the sealing sheet, and slow down the upward movement speed when the hook is moved up and reset after replacing the infusion bottle, which can effectively prevent the infusion bottle from being shaken off by the impact caused by the collision between the support rod and the sleeve when the hook moves up too fast.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] Example:

[0022] Reference Figure 1 - Figure 3 The utility model discloses a mobile infusion device for emergency department, including a chassis 1, a plurality of moving wheels 2 are connected to the bottom of the chassis 1, a sleeve 3 is fixedly connected to the top of the chassis 1, a piston 4 is slidably connected in the sleeve 3, a support spring 5 is arranged between the bottom of the piston 4 and the sleeve 3, a support rod 6 extending out of the sleeve 3 is fixedly connected to the top of the piston 4, and a hook 7 for placing an infusion bottle is arranged at one end of the support rod 6 away from the piston 4.

[0023] In this embodiment, when in use, the infusion bottle is hung on the hook 7, and then the infusion tube is connected to the infusion bottle to start infusion to the patient.

[0024] When the infusion bottle needs to be replaced, in order to make the replacement of the infusion bottle more convenient, the support rod 6 can be pulled down. By applying a downward force to the support rod 6, the support rod 6 moves downward along the axial direction of the sleeve 3, and the height of the hook 7 is lowered, so that medical staff can replace the infusion bottle more easily, which can reduce the pressure on medical staff in a variable manner.

[0025] After the infusion bottle is replaced, the external force applied to the support rod 6 is released, and then the support rod 6 will be reset under the push of the support spring 5, eliminating the step of manual reset, making the use of the infusion device simpler and effectively improving the practicality of the infusion device.

[0026] In a further preferred embodiment of the present invention, Figure 3 As shown, a circular groove 8 is formed at the bottom of the piston 4 , and the circular groove 8 extends into the support rod 6 . A plurality of exhaust holes 9 connected to the circular groove 8 are formed at the bottom of the outer wall of the support rod 6 .

[0027] In this embodiment, the circular groove 8 and the exhaust hole 9 are provided so that the air in the sleeve 3 can flow through the piston 4, and the exhaust hole 9 is used to limit the cross-section through which the air can pass. The air medium is used to provide damping for the movement of the piston 4, thereby preventing the support rod 6 from rising too fast and causing impact when resetting, and making the movement of the support rod 6 smoother.

[0028] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, a sealing sheet 10 is hingedly connected to the support rod 6 above the exhaust hole 9 , and a curved surface that fits with the outer wall of the support rod 6 is provided on one side of the sealing sheet 10 close to the support rod 6 .

[0029] In this embodiment, since the exhaust hole 9 is provided to slow down the air flow and make the air provide damping to the piston 4, the piston 4 will be affected by the resistance whether it moves up or down, which results in an increase in the physical strength required to move the hook 7 down. When the exhaust hole 9 is enlarged, the air flow speed is significantly increased, and the damping force generated by the air on the piston 4 will be reduced, but this will also cause the support rod 6 to increase its rising speed when it is reset under the push of the support spring 5, causing the support rod 6 to collide with the sleeve 3.

[0030] Therefore, the exhaust hole 9 is enlarged, and a sealing sheet 10 is hinged above the support rod 6 at the exhaust hole 9. At this time, the downward movement of the piston 4 will squeeze the air at the bottom of the sleeve 3, and then the air will be squeezed and flow upward through the piston 4, and then the air will push the sealing sheet 10 to open, so that the area of ​​the exhaust hole 9 is increased, so that the damping force received by the piston 4 when it moves downward is reduced, and the hook 7 is quickly adjusted; and when the support spring 5 pushes the piston 4 to move upward, the piston 4 squeezes the air at the top of the sleeve 3, so that the air at the top passes through the piston 4 and moves downward, so that the air will push the sealing sheet 10 and make the sealing sheet 10 fit with the support rod 6, thereby reducing the area of ​​the exhaust hole 9 through the sealing sheet 10, slowing down the passing speed of the air, so that the air exerts a larger damping force on the piston 4, which can effectively slow down the reset speed of the piston 4 and prevent the support rod 6 from rising too fast and colliding with the sleeve 3.

[0031] In a further preferred embodiment of the present invention, Figure 3 As shown, the width of the sealing sheet 10 is greater than the width of the exhaust hole 9, and the length of the sealing sheet 10 is less than the length of the exhaust hole 9, so that when the sealing sheet 10 is in contact with the support rod 6, a gap remains between the sealing sheet 10 and the exhaust hole 9.

[0032] In this embodiment, by making the width of the sealing sheet 10 larger than the width of the exhaust hole 9, the sealing sheet 10 can block the exhaust hole 9 when it is in contact with the support rod 6, and making the length of the sealing sheet 10 smaller than the length of the exhaust hole 9, a gap for air to pass through is retained at the bottom of the exhaust hole 9 when the sealing sheet 10 is in contact with the support rod 6, thereby preventing the sealing sheet 10 from blocking the exhaust hole 9 and preventing air from circulating. In addition, a smaller gap can increase the difficulty of air flow, thereby allowing the air to exert a greater damping force on the piston 4 when it moves upward.

[0033] In a further preferred embodiment of the present invention, Figure 3 As shown, when the sealing sheet 10 is in contact with the support rod 6 , a gap is left between the sealing sheet 10 and the inner wall of the sleeve 3 .

[0034] In this embodiment, by making the sealing sheet 10 fit against the support rod 6, a gap is left between the sealing sheet 10 and the sleeve 3, so that the sealing sheet 10 can rotate around the hinge, so that the sealing sheet 10 can be opened, which has the effect of expanding the area of ​​the exhaust hole 9, thereby reducing the resistance encountered by the piston 4 when moving downward.

[0035] In a further preferred embodiment of the present invention, Figure 1 As shown, a collar 11 is fixedly connected to the top of the sleeve 3, and a placement table 12 for placing medical instruments is fixedly connected to the outer wall of the collar 11.

[0036] In this embodiment, a ring 11 is provided on the outer wall of the sleeve 3, and a placement table 12 is connected to one side of the ring 11, so that some medical instruments can be temporarily placed on the infusion device, so that medical personnel can temporarily store some medical instruments on the infusion device when taking care of patients, making it more convenient for medical personnel to take care of patients.

[0037] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
