Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to an arterial puncture point pressing auxiliary device. Background Technology
[0002] In clinical practice, patients may require arterial blood draws for blood gas analysis due to changes in their condition. Arterial blood can be collected from the radial, femoral, brachial, and dorsalis pedis arteries. After drawing blood from each site, pressure must be applied to stop the bleeding and prevent hematoma, bruising, or even infection at the puncture site. Normally, patients are accompanied by caregivers who can correctly apply pressure to the puncture site after the blood draw. However, there are situations where a patient's condition suddenly worsens, leaving no caregiver present, or the caregiver is unavailable. When a nurse is on duty alone, they must apply pressure to the puncture site for at least 10 minutes after the blood draw, and for patients with bleeding tendencies, this may need to exceed half an hour. During this time, the nurse cannot remove their hand to promptly send the blood sample for testing, affecting the blood analysis results and the clinician's assessment of the patient's condition. Therefore, this utility model is proposed. Utility Model Content

[0027] Example 1
[0028] An arterial puncture point compression aid, such as Figure 1 and Figure 2 As shown, the device includes a human hand model 1, whose fingers and palm can be bent freely. A pressure airbag 2 is fixed to the fingerprint side of the thumb of the human hand model 1. The pressure airbag 2 is connected to an air pump 6 via a pipe 5. The human hand model 1 is equipped with a control panel 8 and an alarm device 10, both of which are connected to the control panel 8. In this embodiment, the control panel 8 is a device integrating a controller and a display screen.
[0029] The hand model 1 is made of medical-grade silicone or foam material, with a solid internal structure and a certain degree of elasticity, allowing it to be molded and the fingers to bend freely. Figure 3 As shown, a mounting plate 12 is fixed inside the wrist of the human hand model 1. Five metal strips 13 are fixed on the mounting plate 12, each located inside one finger. The metal strips 13 are made of shape-memory metal, which facilitates bending of the fingers and palm and maintains a suitable shape. A protective cover 14 is fixed to the end of the metal strip 13 near the fingertip. The protective cover 14 is teardrop-shaped to prevent the metal strip 13 from piercing out of the fingertip during bending, thus improving safety. The protective cover 14 can be made of metal or plastic.
[0030] A circular mounting groove 3 is provided at the point where the compression airbag 2 contacts the human body. A sterile cotton swab 4 is placed in the mounting groove 3. The mounting groove 3 is made of flexible silicone, and its sidewalls are attached to the compression airbag 2 using medical double-sided tape. In use, simply place the sterile cotton swab 4 directly into the mounting groove 3, ensuring it protrudes beyond the outer edge (ensuring contact between the cotton swab 4 and the puncture site), and then attach the mounting groove 3 to the compression airbag 2.
[0031] A pressure sensor is installed on the side wall of the press-fit airbag 2 near the mounting groove 3, and the pressure sensor is connected to the control panel 8. Precise pressure control is difficult using only the air pump 6 and the press-fit airbag 2; the pressure sensor allows for real-time monitoring of the actual pressing pressure. The pressure sensor transmits data to the control panel 8, which, based on a preset optimal pressure value, controls the start / stop of the air pump 6 or adjusts its power to achieve precise pressure control.
[0032] The control panel 8 is located on the web between the thumb and index finger of the hand model 1. It features start / stop buttons and a time adjustment button 9, allowing medical staff to accurately set the compression time based on the puncture type, location, and individual patient differences. An alarm device 10 is located on one side of the control panel 8. This device emits a clear and loud alarm sound when the set time is reached, preventing medical staff from forgetting to compress the puncture site due to busyness or negligence, ensuring sufficient compression time. It can also be set to deflate the cuff at the end of the set time to stop compressions. The control panel 8 can also connect to a remote terminal device (computer or mobile phone) via a built-in wireless transmission module, allowing medical staff to directly monitor the compression status, enhancing its intelligent functionality.
[0033] The wrist of the human hand model 1 houses a power module 11, which provides power to the control panel 8, alarm device 10, and pressure sensor. It also includes a primary protective diaphragm 20, such as... Figure 4 As shown, the disposable protective film 20 is shaped to match the hand model 1, and is slightly larger than the hand model 1. The disposable protective film 20 has an opening 201 at a position corresponding to the mounting groove 3. In use, the disposable protective film 20 is directly attached to the palm side of the hand model 1, which can reduce cross-infection. The disposable protective film 20 is made of medical sterile isolation membrane commonly used in clinical settings.
[0034] Several straps 7 are fixed to the side wall of the air pump 6. When in use, the air pump 6 is fixed to the bed rail or the footboard of the bed by the straps 7 to improve its stability and prevent the air pump 6 from tipping over or moving due to accidental collisions or other accidents. It also helps to keep the connection between the air pump 6 and the compression airbag 2 smooth and prevents the pipe 5 from twisting or falling off, thereby ensuring the normal operation of the compression auxiliary device.
[0035] The human hand model 1 provided by this utility model is not limited to the above content. It can be an improved version of the more automated robotic hand sold on the market, making the operation more intelligent.
[0036] The method of using the arterial puncture point pressing auxiliary device provided by this utility model is as follows: (1) Before puncture, attach the disposable protective film 20 to the human hand model 1 to ensure that it covers completely and fits tightly with the palm side of the human hand model 1; stuff the sterile cotton 4 into the mounting groove 3 so that the sterile cotton 4 protrudes from the outer edge of the mounting groove 3, and then attach the mounting groove 3 to the pressing airbag 2; use the strap 7 to fix the air pump 6 to the guardrail of the bed or the footboard of the bed to ensure its stability. (2) After completing the arterial puncture, the medical staff immediately and tightly attach the thumb portion of the hand mannequin 1, covered with sterile cotton 4, to the puncture site. The staff then shapes the hand mannequin 1 to tightly wrap around the puncture site, maintaining a firm grip on the thumb portion throughout the process. Based on the pressure data displayed on the control panel 8, the staff operates the control panel 8 to control the air pump 6 to inflate or deflate the compression bag 2 until the pressure is adjusted to a suitable value (this value is monitored by the pressure sensor and compared with the preset optimal pressure value, then precisely adjusted by the control panel 8 controlling the air pump 6). After the pressure is adjusted, the staff releases their hand and sets the compression time using the time adjustment button 9 on the control panel 8. Once set, the staff can proceed with other tasks such as sending blood samples for testing. When the set compression time is reached, the alarm device 10 will issue an alarm signal, reminding the staff to remove the auxiliary device promptly. (3) After use, tear off and discard the disposable protective film 20, and remove and discard the disinfectant cotton 4 at the same time; tear off the mounting slot 3 from the pressing airbag 2, and then disinfect and sterilize the mounting slot 3 and the hand model 1 for the next use.
[0037] Example 2
[0038] An arterial puncture point compression aid, such as Figure 5 and Figure 6 As shown, the technical solution in this embodiment is basically the same as that in embodiment 1, except that: this embodiment also includes a handle 15, an anti-slip silicone pad 19, and an elastic restraint belt 16.
[0039] The handle 15 is fixedly connected to the wrist of the human hand model 1, and the air pump 6 is fixed in the handle 15, which reduces the size of the device, reduces the additional space occupied, and makes it convenient for medical staff to carry and use.
[0040] The palm side and palm part of the four fingers (excluding the thumb) of the human hand model 1 are fixed with anti-slip silicone pads 19 to increase the anti-slip properties of the parts in contact with the human body and ensure the stability of the pressing process.
[0041] The elastic restraint strap 16 is fixed to the thumb of the hand model 1 and connected to the back of the hand of the hand model 1 via Velcro. The loop side 18 of the Velcro is fixed to the back of the hand of the hand model 1, and the hook side 17 of the Velcro is fixed to one end of the elastic restraint strap 16. After the auxiliary device is installed, grasp one end of the elastic restraint strap 16 and wrap it around the other four fingers or other parts of the body to make the hook side 17 of the Velcro and the loop side 18 fit together, thus fixing the hand model 1. The number and position of the elastic restraint straps 16 can be set according to the actual clinical operation needs.
[0042] The arterial puncture point compression auxiliary device provided by this utility model has a structure shaped like a palm, with fingers and palm that can be bent at will. It can adjust the fit to the human body according to the puncture site, adjust the compression time, and has an alarm function to avoid prolonged compression affecting blood circulation. It can solve the problem of not having suitable personnel to assist in pressing the arterial blood puncture point in emergency situations in clinical work. On the other hand, it can also reduce hand fatigue and cramps caused by prolonged compression by the person pressing, and has strong practicality.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
