Description

Technical Field

[0001] The utility model relates to the technical field of compression hemostasis devices, in particular to a compression hemostasis device capable of countdown after venous blood sampling and puncture. Background Art

[0002] Venous blood sampling is a method of collecting blood samples by puncturing a vein with a steel needle. The veins used for blood collection are relatively superficial and are usually punctured at the wrist, elbow, or back of the hand. After puncture, the puncture site needs to be compressed for 5-10 minutes to stop bleeding. Incorrect compression can not only lead to complications such as subcutaneous congestion, bleeding, pain, and even limited limb movement, but also affect the clarity of the blood vessels, increase the difficulty of re-puncture, cause pain to the patient, and increase the workload of the nurse.

[0003] Currently, manual compression is the most commonly used method for hemostasis. Medical staff will place cotton balls at the patient's puncture site and let the patient press the blood collection puncture site themselves. Due to the different compliance of patients with the pressing behavior, it is often not long enough, the pressure is not strong enough, and the position is not good. Because the steel needle is inserted into the vein at an angle, the puncture point and the point of puncture into the blood vessel are arranged in front and behind each other. When pressing, the area covered by both points should be taken into account. The literature reports that the pressing time is 5-10 minutes. Whether post-puncture complications occur is also related to factors such as whether the patient is taking anticoagulants. Due to different heights and weights of patients and different disease progression, weak pressure and ineffective pressing may occur in special cases such as children. Therefore, there is an urgent need for a device for pressing and stopping bleeding after venous blood collection puncture with a countdown to ensure the safety of patients after puncture with effective time, appropriate pressure, and accurate position. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a device for pressing and stopping bleeding after venous blood sampling and puncture with a countdown function.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A device for pressing and stopping bleeding after venous blood sampling and puncture with a countdown, comprising an elastic band, an elastic connecting section fixed to the outer wall of the elastic band, an elastic band fixed to the outer wall of the elastic connecting section, a mounting plate fixed to one end of the elastic band, a limiting ring fixed to the outer wall of one side of the mounting plate, an electromagnet fixed to the inner wall of the limiting ring, an elliptical pressure block fixed to the outer wall of the elastic band, a plurality of metal buckles fixed to the outer wall of the other side of the elastic band, and the limiting rings clamped on the outer walls of the metal buckles.

[0007] As a further solution of the present invention: a control box is fixed to the outer wall of the mounting plate, a control panel is provided on the outer wall of the control box, and the electromagnet is electrically connected to the control panel.

[0008] As a further solution of the present invention: a control button is provided on the outer wall of the control box, and the control button is electrically connected to the control panel.

[0009] As a further solution of the present invention: a charging interface is provided on an outer wall of one side of the control box, and a battery is provided on an inner wall of the control box.

[0010] As a further solution of the present invention: an indicator light is fixed to the outer wall of the mounting plate, and the indicator light is electrically connected to the control panel.

[0011] As a further solution of the present invention: a pull ring is provided on the outer wall of the mounting plate.

[0012] As a further solution of the present invention: a pressure sensor is fixed to the inner wall of the elastic band, an outer wall of one side of the pressure sensor is arranged on an outer wall of one side of the elliptical pressure block, and the pressure sensor is electrically connected to the control panel.

[0013] As a further solution of the present invention: a reserved hole is opened on the outer wall of the elastic band.

[0014] The beneficial effects of the utility model are:

[0015] 1. Medical staff can buckle the limit ring on different metal buckles according to the thickness of the patient's elbow, thereby adjusting the pressure of the elastic belt on the elliptical pressure block. Then the medical staff control the electromagnet to open through the control button. At this time, the limit ring will be fixed to the corresponding side of the metal buckle through the magnetic force of the internal electromagnet. At the same time, the medical staff can set the power-on time of the electromagnet through the control panel. After the time is up, the control panel will control the electromagnet to cut off the power, thereby automatically releasing the adsorption and fixation between the metal buckle and the limit ring, preventing the elliptical pressure block from squeezing the patient's puncture site for a long time.

[0016] 2. The medical staff puts the limiting ring on one side of the elastic band on the corresponding metal buckle on one side of the elastic strap. At this time, the pressure sensor installed between the elastic band and the elliptical pressure block can monitor the pressure on the elliptical pressure block in real time. When the pressure on the pressure sensor reaches the set value, the control panel will control the indicator light to light up, indicating that the pressing pressure applied by the elliptical pressure block to the patient's puncture site has reached the pressing and stopping bleeding requirements. The medical staff can buckle the limiting ring on different metal buckles according to the thickness of the patient's elbow, thereby adjusting the pressure of the elastic band and the elliptical pressure block.

[0017] 3. The medical staff wraps the elastic band around the patient's elbow. The reserved hole on one side of the elastic band allows the patient's protruding elbow to be exposed, so that the elastic band can be wrapped around the patient's elbow more closely. The medical staff can charge the battery installed in the control box through the charging port, thereby stably powering the compression hemostasis device. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The outer wall of the control box 16 is provided with a control button 8, which is electrically connected to the control panel 7;

[0029] The outer wall of one side of the control box 16 is provided with a charging interface 15, and the inner wall of the control box 16 is provided with a battery;

[0030] An indicator light 10 is fixed to the outer wall of the mounting plate 11, and the indicator light 10 is electrically connected to the control panel 7;

[0031] The outer wall of the mounting plate 11 is provided with a pull ring 9;

[0032] A pressure sensor 2 is fixed to the inner wall of the elastic band 1. One outer wall of the pressure sensor 2 is arranged on one outer wall of the elliptical pressure block 12. The pressure sensor 2 is electrically connected to the control panel 7.

[0033] The outer wall of the elastic band 6 is provided with a reserved hole 5;

[0034] After the patient completes venipuncture and blood collection, the medical staff first applies an infusion patch or a hemostatic cotton ball to the patient's puncture site. Then, holding the elastic bandage 1, the medical staff aligns the elliptical pressing block 12 with the epidermal puncture site and presses it down, so that the elliptical pressing block 12 is pressed on the puncture site where the infusion patch or hemostatic cotton ball is applied. Since the elliptical pressing block 12 has a large compression area, the elliptical pressing block 12 applied to the patient's epidermal puncture site can cover the puncture point on the outer wall of the blood vessel located at a certain distance from the epidermal puncture point.

[0035] Then the medical staff wraps the elastic band 6 around the patient's elbow. The reserved hole 5 on one side of the elastic band 6 can allow the patient's protruding elbow to leak out, so that the elastic band 6 can be wrapped around the patient's elbow more snugly. Then the medical staff puts the limiting ring 13 on one side of the elastic band 6 on the corresponding metal buckle 3 on one side of the elastic bandage 1. At this time, the pressure sensor 2 arranged between the elastic bandage 1 and the elliptical pressing block 12 can monitor the pressure exerted on the elliptical pressing block 12 in real time. When the pressure exerted on the pressure sensor 2 reaches the set value, the control panel 7 will control the indicator light 10 to light up, indicating that the pressing pressure applied by the elliptical pressing block 12 to the patient's puncture site has reached the pressing and stopping bleeding requirements. The medical staff can buckle the limiting ring 13 according to the thickness of the patient's elbow. The control panel 7 is composed of a single-chip microcomputer, a timing chip and a display screen. The medical staff can charge the battery arranged inside the control box 16 through the charging interface 15, thereby stably powering the pressing hemostasis device.

[0036] Working principle: After the patient completes venipuncture and blood collection, the medical staff first applies an infusion patch or a hemostatic cotton ball to the patient's puncture site. Then, holding the elastic bandage 1, the medical staff aligns the elliptical pressing block 12 with the epidermal puncture site and presses it down, so that the elliptical pressing block 12 is pressed on the puncture site where the infusion patch or hemostatic cotton ball is applied. Since the elliptical pressing block 12 has a large compression area, the elliptical pressing block 12 applied to the patient's epidermal puncture site can cover the puncture point on the outer wall of the blood vessel located a certain distance away from the epidermal puncture point.

[0037] Then the medical staff wraps the elastic band 6 around the patient's elbow. The reserved hole 5 on one side of the elastic band 6 allows the patient's protruding elbow to leak out, so that the elastic band 6 can be wrapped around the patient's elbow more snugly. Then the medical staff puts the limiting ring 13 on one side of the elastic band 6 on the corresponding metal buckle 3 on one side of the elastic bandage 1. At this time, the pressure sensor 2 set between the elastic bandage 1 and the elliptical pressing block 12 can monitor the pressure exerted on the elliptical pressing block 12 in real time. When the pressure exerted on the pressure sensor 2 reaches the set value, the control panel 7 will control the indicator light 10 to light up, indicating that the pressing pressure applied by the elliptical pressing block 12 on the patient's puncture site is The force has reached the requirement of pressing to stop bleeding. The medical staff can buckle the limiting ring 13 on different metal buckles 3 according to the thickness of the patient's elbow, so as to adjust the pressure of the elastic band 6 on the elliptical pressure block 12. Then the medical staff controls the electromagnet 14 to open through the control button 8. At this time, the limiting ring 13 will be fixed to the corresponding side of the metal buckle 3 through the magnetic force of the internal electromagnet 14. At the same time, the medical staff can set the power-on time of the electromagnet 14 through the control panel 7. After the time is up, the control panel 7 will control the electromagnet 14 to cut off the power, thereby automatically releasing the adsorption and fixation between the metal buckle 3 and the limiting ring 13, and avoiding the elliptical pressure block 12 from squeezing the patient's puncture site for a long time.
