Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a radial artery puncture hand fixing device. Background Art

[0002] Radial artery puncture is commonly used in clinical practice for arterial blood gas analysis, monitoring arterial pressure, cardiovascular intervention, etc. Successful radial artery puncture is a prerequisite for establishing radial artery access and smoothly performing radial artery intervention operations. However, compared with the femoral artery, the radial artery is relatively small and prone to muscle spasm. Therefore, the difficulty of radial artery puncture is higher than that of femoral artery, especially for patients with abnormal radial artery development, stress and anxiety. During radial artery puncture, it is best to raise the patient's wrist and keep the elbow in a hyperextended state, which is helpful to improve the success rate of radial artery puncture.

[0003] During the existing puncture process, medical staff will use tape to fix their hands on the table or use one hand to fix the patient's hand, and then expose the puncture point by rotating or raising the wrist to facilitate puncture. This has the following shortcomings:

[0004] 1. The fixation effect of adhesive tape is limited. During the puncture process, the patient's hand may unconsciously move sideways or rotate, which increases the difficulty of puncture for medical staff. In addition, when the adhesive tape is removed, residual adhesive is likely to remain on the patient's hand, which reduces the patient's comfort level.

[0005] 2. During the puncture process, the patient may retract his hand when the needle is inserted due to fear. When fixing the patient's hand, the adhesive tape is generally placed across the patient's palm to press the patient's hand against the table. The above-mentioned adhesive tape fixation cannot prevent the patient's hand from retracting and moving, and the fixation effect is poor.

[0006] Therefore, how to design a radial artery puncture hand fixation device that can solve the above-mentioned technical problems is a technical problem that needs to be solved. Utility Model Content

[0007] In order to solve the above problems, the purpose of the utility model is to provide a radial artery puncture hand fixation device, which solves the problem that the existing fixation of the patient's hand has poor fixation effect and cannot prevent the patient's hand from retracting, moving laterally and rotating, which increases the difficulty of puncture for medical staff.

[0008] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a fastening clamp and a fixing plate rotatably arranged on the fastening clamp; fasteners for fixing the palm are arranged on both sides of the front part of the fixing plate; a plurality of finger fixing arc plates are arranged at the upper end surface of the fixing plate corresponding to the finger positions, the inner sides of the plurality of finger fixing arc plates are covered with annular air bags, a mounting groove is also arranged at the rear part of the upper end surface of the fixing plate, and an inflatable air bag cushion is arranged in the mounting groove; a driving component for inflating the annular air bag and the inflatable air bag cushion is also arranged in the fixing plate, and the driving component includes a micro pump 1 connected to the plurality of the annular air bags, a micro pump 2 connected to the inflatable air bag cushion, a control key 1 arranged on the outer side surface of the fixing plate and connected to the micro pump 1 by telecommunication, a control key 2 arranged on the outer side of the fixing plate and connected to the micro pump 2 by telecommunication, and a power supply for providing electric energy to the micro pump 1 and the micro pump 2.

[0009] Furthermore, the number of the finger fixing arc plates and the number of the annular airbags are both 4.

[0010] Furthermore, the lengths of the four finger-fixing arc plates are different, and the lengths of the four annular airbags are the same as the inner lengths of the four finger-fixing arc plates.

[0011] Furthermore, the fasteners are Velcro straps connected to each other via Velcro.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model is provided with a finger fixing arc plate and an annular air bag is covered on its inner side. When the patient is undergoing puncture, the fingers pass through the finger fixing arc plate respectively, and the micro pump inflates the annular air bag to fit tightly with the patient's fingers, so as to fix the patient's fingers and prevent the patient's hand from retracting and moving, thereby increasing the fixing effect of the utility model and reducing the work difficulty of medical staff. The utility model is provided with a Velcro strap for fixing the patient's palm to fix the patient's palm and prevent the patient from moving laterally or rotating the palm.

[0014] 2. The utility model sets an inflatable airbag cushion at the rear of the fixing plate corresponding to the patient's wrist position, and inflates the airbag cushion in two directions through a micro pump to expand it and lift the patient's wrist, so that the patient's wrist is in a hyperextension state, fully exposing the wrist, and reducing the difficulty of puncture for medical staff.

[0021] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0022] See also Figure 1-3 As shown, the scheme includes a fastening clamp 2 and a fixing plate 1 rotatably arranged on the fastening clamp 2. The fastening clamp 2 and the fixing plate 1 are rotatably connected via a rotating shaft to realize multi-directional rotation of the fixing plate 1, so that medical staff can adjust the use angle of the fixing plate 1 according to the patient's hand position when using it.

[0023] The front sides of the fixing plate 1 are provided with fasteners 11 for fixing the palm; the upper end surface of the fixing plate 1 is provided with a plurality of finger fixing arc plates 12 corresponding to the finger positions, and the inner sides of the plurality of finger fixing arc plates 12 are covered with annular airbags 121; the upper end surface of the fixing plate 1 is also provided with a mounting groove 13 at the rear, and an inflatable airbag cushion 131 is arranged in the mounting groove 13; the fixing plate 1 is also provided with a driving component 14 for inflating the annular airbag 121 and the inflatable airbag cushion 131, the The driving assembly 14 includes a micro pump 141 connected to the plurality of annular airbags 121, a micro pump 2 143 connected to the inflatable airbag cushion 131, a control key 142 provided on the outer side of the fixed plate 1 and electrically connected to the micro pump 1 141, a control key 2 144 provided on the outer side of the fixed plate 1 and electrically connected to the micro pump 2 143, and a power supply 145 for providing electrical energy to the micro pump 1 141 and the micro pump 2 143.
