[0027] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figure 1 shown, in this embodiment, an infusion protector is provided, including: a support plate 1, a fixing part 2 and a fixing band 3.

[0029] The fixing part 2 is arranged at one end of the support plate 1. The support plate 1 is in the shape of a long plate. The fixing part 2 can be arranged on the end face at one end in the length direction of the support plate 1. The fixing part 2 has four through holes 21 for the patient's fingers to extend out. For example, the four through holes 21 can be arranged according to the distribution of the finger joints of the human hand, so that the patient's index finger, middle finger, ring finger and little finger can extend out from the corresponding through holes 21, and each through hole can fix the joint close to the palm.

[0030] A notch 11 is arranged on the edge of the support plate 1. The notch 11 can be an arc-shaped notch. The notch 11 is arranged close to the fixing part 2. The arrangement position of the notch 11 can cooperate with the arrangement position of the through hole 21. After the patient's finger fully extends into the through hole 21, the thumb is exactly located at the notch 11. The through hole 21 and the notch 11 can limit the movement of the proximal palmar joint, and the movement of the distal palmar joint will not affect the stability of the connection of the infusion needle. Such an arrangement can not only prevent the patient's hand from moving, but also avoid the discomfort caused by the patient's finger staying still for a long time. A notch 11 can be arranged on each of the two opposite edges of the support plate 1, so that the same support plate 1 can be adapted to the left or right hand. Of course, different support plates can also be provided according to the structures of the left or right hand.

[0031] One end of the fixing band 3 is connected to the edge of the support plate 1 in the width direction, and the other end is connected to another edge of the support plate 1 in the width direction, which is used to fix the patient's hand and / or arm to prevent the support plate 1 from separating from the patient's hand and / or arm.

[0032] During use, medical staff can guide the patient to place the hand and forearm on the support plate 1. The index finger, middle finger, ring finger, and little finger can respectively extend out from the four through holes 21 of the fixing part 2 to fix the joints of the index finger, middle finger, ring finger, and little finger close to the palm. The thumb is aligned with the notch 11. After the palm part of the patient is fixed, the fixing band 3 can be fixed to the patient's hand and / or arm, and then the infusion needle is punctured and the adhesive tape is fixed. The support plate 1 can support the patient's palm and cooperate with the fixing part 2 to ensure that the patient's hand cannot move. The cooperation of the support plate 1 and the fixing band 3 can prevent the patient's hand and / or arm from separating from the support plate 1 and prevent the patient's wrist from moving, so that the patient keeps the hand, wrist, and forearm in a static state until the infusion is completed. Such a setting can prevent the patient from causing the displacement or dislodgment of the infusion needle due to hand movement and ensure the stable progress of the infusion.

[0033] As Figure 1 and Figure 2 shown, in this embodiment, the support plate 1 is made of a flexible material, and a support steel bone 121 is arranged inside the support plate 1. The support steel bone 121 extends along the length direction of the support plate 1. The flexible material can fit the palm, wrist, and arm skin to avoid causing discomfort to the patient. The support steel bone 121 can ensure the support strength of the support plate 1 and prevent the support plate 1 from bending.

[0034] As Figure 1 and Figure 2 shown, in this embodiment, a support steel plate 122 is arranged inside the support plate 1 near the fixing part 2. The support steel bone 121 is connected to the support steel plate 122. The support steel plate 122 can prevent the support plate 1 from bending caused by the contraction movement of the patient's palm and improve the stability of the support of the support plate 1.

[0035] As Figure 1 and Figure 2 shown, in this embodiment, four support steel bones 121 are arranged at intervals inside the support plate 1 to further improve the stability of the support plate 1. The flexible material is silica gel, and the silica gel is formed on the support steel bone 121 and the support steel plate 122 through a process of encapsulation injection molding.

[0036] As Figure 1 and Figure 3 shown, in this embodiment, a plurality of ventilation holes 13 are opened on the end face of the support plate 1. The ventilation holes 13 enable the support plate 1 to have a ventilation and heat dissipation effect, which can prevent the patient's hand and / or arm from sweating and causing discomfort.

[0037] As Figure 1 and Figure 3 shown, in this embodiment, at least three columns of ventilation holes 13 are arranged at intervals on the end face of the support plate 1. Each column of ventilation holes 13 is located between two adjacent support steel frames 121, and some ventilation holes penetrate through the support steel plate 122. Such an arrangement can increase the number of ventilation holes 13 while taking into account the support strength of the support plate 1.

[0038] As Figure 1 shown, in this embodiment, the fixing part 2 is arranged on the end face of the support plate 1, and the extending direction of the through hole 21 is the same as that of the support plate 1, avoiding discomfort when the patient inserts a finger.

[0039] As Figure 1 shown, in this embodiment, the fixing part 2 is made of a hard material, and an annular silica gel sleeve that fits the hole wall is provided in the through hole 21. When the patient inserts a finger into the through hole 21, the annular silica gel sleeve can change its shape according to the thickness of the patient's finger, so as to adapt to the finger sizes of most patients, and can also avoid discomfort caused by the hard fixing part 2 to the patient.

[0040] As Figure 1 and Figure 3 shown, in this embodiment, at least three fixing straps 3 are arranged at intervals on the edge of the support plate 1. At least three fixing straps 3 can respectively fix the patient's hand, wrist and arm, further preventing the patient's hand from moving.

[0041] As Figure 1 shown, in this embodiment, at least one end of the fixing strap 3 is connected to the edge of the support plate 1 through a magic tape 31. The male and female tapes of the magic tape 31 can be respectively arranged at the ends of the support plate 1 and the fixing strap 3, so as to facilitate medical staff to fix the patient's hand and / or arm.

[0042] Although the embodiments of the present utility model have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present utility model, and such modifications and variations all fall within the scope defined by the appended claims.
