Description

Technical Field

[0001] The invention relates to the technical field of medical supplies, in particular to a blood drawing baffle device for pediatric surgical care. Background Art

[0002] The diagnosis and treatment scope of pediatric surgery covers multiple sub-specialties such as neonatal surgery, pediatric general surgery, pediatric thoracic surgery, pediatric urology, pediatric neurosurgery, pediatric otolaryngology-head and neck surgery, and pediatric orthopedics. In clinical nursing work, blood sample collection is one of the routine examination items, but due to the low degree of cooperation of child patients, they are prone to crying, limb movement, etc. during the blood collection process, which affects the smooth progress of the blood collection operation.

[0003] The pediatric blood collection auxiliary devices currently used clinically have obvious shortcomings, mainly manifested in poor fixing functions and inability to effectively restrain the limb activities of children. When the child's limbs shake during the blood collection process, it will not only increase the difficulty of puncture, but also may affect the quality of the blood sample. In severe cases, it may even lead to blood collection failure or cause medical safety hazards. The Chinese utility model patent with application number 202022969613.X discloses a blood collection baffle device for pediatric surgical care. The application achieves the effect of easy fixation through the arrangement of a base, a bracket, a baffle plate, a protective shell, a first arc-shaped fixed plate, a second arc-shaped fixed plate, a chute, a slider, a mobile plate, a drive motor, a drive shaft, a gear, a rack plate, a mobile column, a sliding sleeve, a sliding column, a buffer block, a buffer spring, a compression spring, a buffer plate and a buffer column. However, the utility model patent has many parts, a large volume, and a low aesthetic level, which is not conducive to placement in the hospital, and children are also prone to rejection of the device; in addition, the utility model clamps the child's arms or legs through a clamping plate. Although there is a spring buffer, there is still a risk of causing injury to the child.

[0032] The edges of the lower half circle 1, the upper half circle 2, the baffle 5 and the eaves 6 are all provided with arc chamfers.

[0033] The inner walls of the lower half circle 1 and the upper half circle 2 are both provided with a silicone layer.

[0034] A cartoon pattern is drawn on the surface of the baffle 5 on the side facing away from the eaves 6 .

[0035] Working principle of this embodiment:

[0036] When the present embodiment is in operation, the child's arm or leg is placed on the lower half circle 1, and the upper half circle 2 is closed with the lower half circle 1 by rotational connection, forming an arc-shaped fixed structure. The strap 3 and the adhesive layer 4 are bonded by Velcro to ensure that the upper half circle 2 and the lower half circle 1 are tightly fixed, effectively restraining the child's limb movement. The baffle 5 is arranged on the circumferential outer wall of the upper half circle 2, extending outward and having an eaves 6. The design of the baffle 5 and the eaves 6 can block the child's line of sight, reduce his fear of the blood collection process, and thus reduce the possibility of crying and limb movement.

[0037] A silicone layer is provided on the inner wall of the lower half circle 1 and the upper half circle 2 to provide soft protection to avoid damage to the skin of the child. At the same time, a cartoon pattern is drawn on the side of the baffle 5 facing away from the eaves 6 to attract the attention of the child, increase the affinity of the device, and reduce the child's rejection psychology.

[0038] The lower half circle 1 is detachably fixed on the base 17. When drawing blood from some special children with strong mobility, in order to avoid limb contusion of the children, the lower half circle 1 can be removed from the base 17. At this time, the upper half circle 2 and the lower half circle 1 are fixed on the limbs of the children, and the baffle 5 and the eaves 6 play the role of shielding the line of sight. At this time, the children can be held by their family members for blood drawing.

[0039] The silicone layer on the inner wall of the lower half circle 1 and the upper half circle 2 provides soft protection to avoid damage to the skin of the child and ensure the safety of the blood collection process.

[0040] In this embodiment, through the closed structure of the lower half circle 1 and the upper half circle 2 and the bonding of the strap 3 and the adhesive layer 4, the device can effectively restrain the limb movement of the child, reduce the shaking of the limbs during the blood collection process, and improve the smooth progress of the blood collection operation. The design of the baffle 5 and the eaves 6 blocks the sight of the child, reduces his fear of the blood collection process, thereby reducing the possibility of crying and limb movement, and improving the success rate of blood collection. The cartoon pattern on the baffle 5 increases the affinity of the device, reduces the rejection of the child, improves his cooperation, and further ensures the smooth progress of the blood collection operation. The lower half circle 1 is detachably fixed to the base 17. When drawing blood for some special children with excessive mobility, the lower half circle 1 can be removed from the base 17, and the upper half circle 2 and the lower half circle 1 are fixed on the child's limbs. The baffle 5 and the eaves 6 play a role in blocking the sight. At this time, the child can be held by his family for blood collection. This embodiment effectively solves the problems of poor fixing function, low cooperation of children, and difficult blood collection operation in the prior art, and has significant beneficial effects.
