[0002] Invasive arterial blood pressure monitoring is an important means of monitoring vital signs in critically ill patients. It involves inserting an arterial catheter into an artery to directly measure blood pressure within the artery. Invasive arterial blood pressure monitoring provides continuous, reliable, and accurate blood pressure data and is suitable for intraoperative and postoperative monitoring of patients in shock, severe illness, severe peripheral vasoconstriction, undergoing major surgery or life-threatening surgery, as well as other high-risk patients.
[0003] Invasive arterial blood pressure monitoring typically uses an arm-type invasive blood pressure kit, which is secured to the outside of the arm with a strap. However, existing straps are configured with buttons and fixing holes, which do not allow for stepless adjustment. Since the human arm varies in thickness, this affects the stability of the invasive blood pressure kit and the convenience of daily use for medical staff.

[0008] In some embodiments, the vent is provided with a one-way valve to allow gas to be introduced into the chamber.
[0009] In some embodiments, the width of the retaining strap matches the width of the mounting hole.
[0010] In some embodiments, the surface of the fixing strap is provided with spaced convex structures to increase the friction between the fixing strap and the fixing clip.
[0011] In some embodiments, the convex structure is a cylindrical protrusion that is spaced apart at both ends of the fixing band.
[0012] In some embodiments, the height of the convex structure is 0.5-1.5 mm.
[0013] In some embodiments, the fixing clip has a H-shaped structure with a fixing plate disposed in the middle, and the fixing plate is offset along the thickness direction of the fixing clip.
[0014] In some embodiments, the surface of the fixing plate is provided with raised ribs, and the number of raised ribs is multiple and evenly distributed.

[0027] A schematic diagram of a fixation device for an invasive blood pressure kit according to this utility model is shown below. Figure 1 As shown. The fixation device for the invasive blood pressure kit includes a fixation strap 10 and a fixation clip 20, the end of which passes through the mounting hole 31 of the invasive blood pressure kit 30 and is locked by the fixation clip 20.
[0028] Furthermore, the fixing belt 10 is provided with a chamber 11, such as... Figure 3 As shown, the chamber 11 is arranged along the length direction of the fixing belt 10; the fixing belt 10 is also equipped with Figure 2 The vent 12 shown is connected to the chamber 11 to allow gas to be introduced into the chamber 11, causing the fixing band 10 to inflate and abut against the fixing clip 20.
[0029] In this invention, the fixing strap 10 is made of hard rubber, which has a certain degree of elasticity. The interior of the fixing strap 10 forms a sealed chamber 11, such as... Figure 3 As shown.
[0030] Figure 2In the illustrated embodiment, a one-way valve is disposed inside the vent hole 12, so as to facilitate gas delivery toward the chamber 11.
[0031] In some embodiments, the vent hole 12 is generally not disposed at the middle position of the fixing strap 10, so as to prevent the vent hole 12 from being located at the lower part of the arm and causing discomfort during use.
[0032] Further, the width of the fixing strap 10 matches the width of the mounting hole 31. Specifically, the width of the fixing strap 10 is slightly smaller than the width of the mounting hole 31, so that the fixing strap 10 can pass through the mounting hole 31 to be connected to the invasive blood pressure kit 30.
[0033] As another embodiment of the present utility model, spaced protruding structures 13 are disposed on the surface of the fixing strap 10, to increase the friction force between the fixing strap 10 and the fixing clip 20.

[0036] Ribs 21a are disposed on the surface of the fixing plate 21, and the number of the ribs 21a is multiple and are uniformly arranged. Figure 5 In the illustrated embodiment, the number of the ribs 21a is four, which are substantially uniformly distributed on the upper surface of the fixing plate 21.
[0037] Further, the ribs 21a are strip-shaped structures, which are arranged along the length direction of the fixing plate 21, to increase the friction force between the fixing clip 20 and the fixing strap 10.
[0038] Figure 4 is a schematic diagram of the connection between the fixing strap 10 and the hand-held air bag 40 provided by an embodiment of the present utility model. After the fixing strap 10 is fixed by the fixing clip 20, the air tube end of the hand-held air bag 40 is connected to the vent hole 12, to inflate the chamber 11 of the fixing strap 10, so that the fixing strap 10 is inflated to fully abut against the fixing clip 20, thereby achieving reliable fixation of the invasive blood pressure kit 30.
[0039] The use process of the fixing device for an invasive blood pressure kit provided by the present utility model is briefly described as follows:
[0040] First, the invasive blood pressure kit 30 is pre-positioned on the outer side of the arm, which is located at the fourth intercostal space on the midaxillary line;
[0041] Next, wrap the fixation strap 10 around the back of the arm and pass the end of the fixation strap 10 through the mounting hole of the invasive blood pressure kit 30 to pre-tighten the fixation strap 10 by means of the fixation clip 20.
[0042] Finally, the tracheal end of the handheld airbag 40 is connected to the ventilation port 12 to inflate it toward the chamber 11 of the fixation strap 10, so that the fixation strap 10 inflates and fully abuts against the fixation clip 20, thereby achieving reliable fixation of the invasive blood pressure kit 30.
[0043] Compared with the shortcomings and deficiencies of the prior art, the present invention provides a fixation device for an invasive blood pressure kit, which has a reasonable structure, is easy to operate, and can flexibly adjust the tightness of the fixation as needed to expand the application range of invasive blood pressure measurement; the fixation band has an internal cavity to abut against the fixation clip through expansion, and the surface of the fixation band is equipped with a convex structure to increase the friction between the fixation band and the fixation clip and improve the reliability of fixation.
[0044] This utility model is not limited to the above-described embodiments. Anyone can derive other products in various forms under the guidance of this utility model.
