Description

Technical Field

[0001] The present invention relates to the technical field of nursing equipment, and particularly to an auxiliary device for blood collection from children during physical examinations. Background Art

[0002] During the blood collection process for children's physical examinations, due to limited cognitive abilities, children have difficulty understanding this medical behavior of blood collection; facing the blood collection needle, they often suddenly struggle due to fear or pain; such struggles are very likely to lead to serious consequences, such as the displacement of the needle, which obstructs the blood collection process and makes it impossible to smoothly obtain sufficient blood volume for testing; blood vessel rupture, which may cause local hematoma and increase the pain of children; or even accidentally stabbing other tissues, causing additional harm to the children's bodies; in addition, the unsmooth blood collection process will prolong the blood collection time, resulting in an increase in the time children are exposed to pain and anxiety, thereby increasing the probability of fainting at the sight of a needle, crying, vomiting or suffocation; currently, although there are some simple fixation methods, such as medical staff manually fixing the children's limbs, this method not only consumes manpower, but also has limited fixation effect and is difficult to cope with the situation of children's violent struggles; some existing fixation devices are either complex in structure and inconvenient to operate, or cannot well meet the needs of children of different ages and body types, and cannot effectively solve many problems during children's blood collection. Summary of the Invention

[0003] In view of the problems existing in the use of some fixation devices during the blood collection process for children's physical examinations, the present invention is proposed.

[0004] Therefore, the object of the present invention is to provide an auxiliary device for blood collection from children during physical examinations, which can effectively fix the children's limbs, reduce the risks of needle displacement, blood vessel rupture and accidental stabbing caused by children's struggles during the blood collection process, while shortening the blood collection time, reducing the duration of children's exposure to pain and anxiety, and reducing the probability of fainting at the sight of a needle, crying, vomiting or suffocation.

[0005] To achieve the above object, the present invention provides the following technical solution:

[0006] An auxiliary device for blood collection from children during physical examinations, comprising a support plate, the four corners of the top surface of the support plate are fixedly connected to an installation frame through support columns, and a light-shielding mirror is fixedly arranged on the inner wall of the installation frame;

[0007] Guide blocks are respectively movably arranged at both ends of the top surface of the support plate, and a semi-circular fixing arm is fixedly arranged on the surface of each guide block. A soft silicone pad is arranged inside the semi-circular fixing arm, and a number of ventilation holes are opened to improve the comfort of children during use. The two groups of semi-circular fixing arms are connected by a pleated connecting belt;

[0008] On one side of each of the two groups of the guiding blocks, an adjusting assembly is respectively arranged. The function of the adjusting assembly is to adjust the horizontal position of the guiding blocks on the supporting plate, so as to realize the effective limiting of the child's arm by the two semi-circular fixing arms.

[0009] Preferably, the adjusting assembly includes an adjusting slide rod. The upper and lower ends of the adjusting slide rod are respectively fixedly connected to the mounting frame and one side of the supporting plate. Slide sleeve A and slide sleeve B are respectively sleeved on the outer side of the adjusting slide rod in a sliding manner, and slide sleeve B is located above slide sleeve A. A transmission rod is rotatably installed on the outer side of slide sleeve A, and the other side of the transmission rod is rotatably connected to the guiding block. By moving slide sleeve A, the transmission rod is driven to move the guiding block.

[0010] Preferably, a spring frame is sleeved on the outer side of the adjusting slide rod. One end of the spring frame is fixedly connected to the bottom of the adjusting slide rod, and the other end is fixedly connected to the outer side of slide sleeve A. The spring frame plays a certain role in assisting the reset. A threaded hole is opened in slide sleeve B, and a fixing nut is threadedly connected in the threaded hole. The fixing nut is used to fix the position of slide sleeve B, and thus indirectly fix the positions of slide sleeve A and the guiding block.

[0011] Preferably, positioning blocks are fixedly installed on the surface of the supporting plate and on one side of the supporting column. A guiding rod is fixedly installed between the supporting column and the positioning block, and a transmission block is movably sleeved on the outer side of the guiding rod. The transmission block is fixedly connected to one end of the corresponding guiding block.

[0012] Preferably, the two groups of slide sleeve Bs are fixedly connected by a connecting rod, and a handle is fixedly installed at one end of the connecting rod. By holding the handle, the two groups of slide sleeve Bs can be conveniently moved simultaneously, and thus the positions of the two groups of guiding blocks can be adjusted synchronously, and the operation is more convenient and efficient.

[0013] Preferably, a placing plate B is fixedly installed on one side of the supporting plate, and a placing rubber pad is fixedly installed on the upper surface of the placing plate B. The placing rubber pad is made of a skin-friendly soft material, which is convenient for placing the child's blood-sampling hand.

[0014] Preferably, a placing plate A is fixedly installed on one side of the mounting block, and toys that can attract the child's attention can be placed in the placing plate A to relieve the child's tension and fear.

[0015] Preferably, a fixing frame is fixedly arranged on the surface of the guiding block at one end of the supporting plate, and a magic tape part is fixedly arranged on the surface of the guiding block at the other end. A colloidal bandage is fixedly arranged at one end of the fixing frame, and one end of the colloidal bandage is adhesively fixed to the magic tape part through the magic tape. After the child's arm is placed in the semi-circular fixing arm, the arm can be further restricted by the colloidal bandage to enhance its auxiliary fixing effect.

[0016] In the above technical solution, the technical effects and advantages provided by the present invention:

[0017] In the present invention, structures such as a semi-circular fixing arm, an adjusting component, and a colloidal bandage are used to effectively fix and limit a child's arm, greatly reducing the risks of needle displacement, blood vessel rupture, and accidental stabbing of other tissues caused by a child's struggle during blood collection, thus ensuring the child's physical safety. Specifically, the soft silicone pad on the inner side of the semi-circular fixing arm can fit the child's arm, and the ventilation holes ensure comfort. The adjusting component can flexibly adjust the fixing degree according to the thickness of the child's arm. The colloidal bandage further enhances the fixing and limiting effect. The stable fixing and limiting effect enables medical staff to perform blood collection operations more smoothly, reducing the interruption of blood collection caused by a child's struggle, thereby shortening the blood collection time. This means that the duration of the child's exposure to pain and anxiety is reduced, and the probability of fainting, crying, vomiting, or suffocation is decreased.

[0018] In the present invention, through the adjusting component, the position of the semi-circular fixing arm can be flexibly adjusted according to the thickness of the arms of children of different ages and body types to effectively limit the child's arm. This adjustable design enables this auxiliary device to adapt to the needs of different children and has stronger versatility. Moreover, the design of the adjusting component makes the fixing process simple to operate. By holding the handle, two sets of sliding sleeves B can be moved simultaneously, and then the positions of two sets of guiding blocks can be adjusted synchronously to effectively limit the child's arm with the semi-circular fixing arm. Then, the fixing can be completed by rotating the fixing nut on one side. In addition, due to the auxiliary reset function of the spring frame, after blood collection for one child is completed, when the medical staff loosens the fixed fixing nut, the elastic force of the spring frame will take effect, pushing the guiding blocks to move to both sides. At the same time, with appropriate assistance from the medical staff, the reset operation can be quickly completed. This not only improves the convenience of operation but also enhances the stability of the entire adjustment process, making subsequent use smoother. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0028] The embodiments of the present invention disclose a blood collection assistant for physical examination of children.

[0029] Referring to Figures 1-4 , a blood collection assistant for physical examination of children includes a support plate 3. The four corners of the top surface of the support plate 3 are fixedly connected to the installation frame 1 through support columns 2, and a light-shielding mirror 5 is fixedly provided on the inner wall of the installation frame 1; the light-shielding mirror 5 mainly plays roles such as relieving the fear psychology of children, reducing external interference, and protecting the operation environment of medical staff, as follows;

[0030] Relieving fear psychology: Children, especially infants and young children, have an instinctive fear of sharp needles, blood, etc. in the blood collection scene; the light-shielding mirror 5 is installed on the inner wall of the installation frame 1, which can block the sight of children and prevent them from directly seeing things that are likely to cause fear such as blood collection needles and blood, thereby psychologically reducing their resistance and fear of blood collection, reducing struggles caused by fear, and making the blood collection process smoother;

[0031] Reducing external interference: Strong light, personnel movement, equipment, etc. in the blood collection environment may distract children's attention and increase their uneasiness; the light-shielding mirror 5 can block part of the light, create a relatively soft and quiet small environment, reduce the interference of external factors on children, help them maintain a relatively calm state, and facilitate blood collection operations;

[0032] On both ends of the top surface of the support plate 3, guiding blocks 8 are movably arranged respectively, and on the surface of each guiding block 8, a semi-circular fixed arm 10 is fixedly arranged. Inside the semi-circular fixed arm 10, a soft silica gel pad is arranged, and a number of ventilation holes are opened to improve the comfort level when children use it. The two groups of semi-circular fixed arms 10 are connected by a corrugated connecting belt 11;

[0033] On one side of the two groups of guiding blocks 8, adjusting components 9 are respectively arranged. The function of the adjusting component 9 is to adjust the horizontal position of the guiding block 8 on the support plate 3, so as to realize the effective limit of the two groups of semi-circular fixed arms 10 on the child's arm.

[0034] The adjusting component 9 includes an adjusting slide rod 15. The upper and lower ends of the adjusting slide rod 15 are respectively fixedly connected with the mounting frame 1 and one side of the support plate 3. Slide sleeves A17 and B19 are respectively sleeved on the outside of the adjusting slide rod 15, and the slide sleeve B19 is located above the slide sleeve A17. A transmission rod 18 is rotatably installed on the outside of the slide sleeve A17, and the other side of the transmission rod 18 is rotatably connected with the guiding block 8. By moving the slide sleeve A17, the transmission rod 18 is driven to move the guiding block 8.

[0035] A spring frame 16 is sleeved on the outside of the adjusting slide rod 15. One end of the spring frame 16 is fixedly connected with the bottom of the adjusting slide rod 15, and the other end is fixedly connected with the outside of the slide sleeve A17. The spring frame 16 plays a certain role in assisting in resetting. A threaded hole is opened in the slide sleeve B19, and a fixing nut 20 is threadedly connected in the threaded hole. The fixing nut 20 is used to fix the position of the slide sleeve B19, and thus indirectly fix the positions of the slide sleeve A17 and the guiding block 8;

[0036] It should be noted that with reference to Figure 5 , in the present invention, it is considered that when medical staff may control the semi-circular fixed arm 10 to limit the patient's arm, the patient's arm may be overly squeezed. Therefore, a second spring frame 25 is sleeved between the slide sleeve A17 and the slide sleeve B19 on the outside of the adjusting slide rod 15. In this way, the second spring frame 25 enables the semi-circular fixed arm 10 to move slightly within a certain range, thereby increasing a certain buffering effect.

[0037] On the surface of the support plate 3 and on one side of the support column 2, positioning blocks 21 are fixedly installed. A guiding rod 22 is fixedly installed between the support column 2 and the positioning block 21, and a transmission block 23 is movably sleeved on the outside of the guiding rod 22. The transmission block 23 is fixedly connected with one end of the corresponding guiding block 8.

[0038] The two groups of slide sleeves B19 are fixedly connected by a connecting rod 24, and a handle 25 is fixedly installed at one end of the connecting rod 24. By holding the handle 25, the two groups of slide sleeves B19 can be conveniently moved simultaneously, and thus the positions of the two groups of guiding blocks 8 can be adjusted synchronously, and the operation is more convenient and efficient;

[0039] This design takes into account that medical staff need to adjust the position of the guide block 8 one by one and then fix the sliding sleeve B19 one by one. When facing the problem of slow efficiency during blood collection for active children or class club organizations, the connecting rod 24 is designed. In this way, only one side of the sliding sleeve B19 needs to be fixed to achieve fixation, and only by moving the handle 25 can the guide block 8 be moved simultaneously, greatly increasing the efficiency of the limiting arm.

[0040] One side of the support plate 3 is fixedly installed with a placement plate B6, and the upper surface of the placement plate B6 is fixedly installed with a placement rubber pad 7. The placement rubber pad 7 is made of skin-friendly soft material, which is convenient for placing the hand of the child for blood collection.

[0041] One side of the mounting block is fixedly installed with a placement plate A4, and toys that can attract children's attention can be placed in the placement plate A4 to relieve the tension and fear of children.

[0042] On the surface of the guide block 8 at one end of the support plate 3, a fixing frame 12 is fixedly provided, and on the surface of the guide block 8 at the other end, a magic tape part 14 is fixedly provided. One end of the fixing frame 12 is fixedly provided with a colloidal bandage 13, and one end of the colloidal bandage 13 is adhesively fixed to the molded sticker part through the magic tape. After the child's arm is placed in the semi-circular fixing arm 10, the arm can be further restricted by the colloidal bandage 13 to enhance its auxiliary fixing effect.

[0043] In the present invention, basic blood collection assistance operation

[0044] Medical staff place the blood collection aid on a stable table and check whether all components are intact; put a colorful and cute cartoon-patterned sounding toy, such as a singing teddy bear doll, in the placement plate A4, and prepare blood collection supplies such as iodophor cotton balls and cotton swabs on the placement rubber pad 7 of the placement plate B6.

[0045] Guide a thinner child to sit on the chair and place his / her arm flat on the placement rubber pad 7 of the placement plate B6; medical staff hold the handle 25 and gently push downward to move the two sliding sleeves B19 synchronously, driving the sliding sleeve A17 to slide along the adjustment slide rod 15. The sliding sleeve A17 pushes the guide block 8 through the transmission rod 18 to make the semi-circular fixing arm 10 gradually approach the child's arm; when the semi-circular fixing arm 10 fits the child's arm, tighten the fixing nut 20 on one side of the sliding sleeve B19 to fix the position of the semi-circular fixing arm 10; since the child's arm is thinner, the semi-circular fixing arm 10 can fit tightly but not too tightly under the action of the adjustment component 9, and the pleated connecting band 11 can fill the bottom seam, and the rounded corners of the clamp of the semi-circular fixing arm 10 can also prevent it from clamping the patient's arm;

[0046] Bond the colloidal bandage 13 at one end of the fixed frame 12 to the Velcro part 14 through Velcro to further fix the child's arm; under the occlusion of the light-shielding mirror 5, the medical staff uses the toy on the placement plate A4 to attract the child's attention, making the child's eyes focus on the toy, and then smoothly perform the blood collection operation; when preparing for blood collection, the medical staff first picks up the iodine cotton ball and cotton swab, places the child's finger on the placement rubber pad 7, disinfects the finger with the iodine cotton ball, and after disinfection, uses the puncture needle to pierce the child's finger, and then gently squeezes the finger to collect blood. During the blood collection process, the medical staff will gently press the child's finger on the placement rubber pad 7, which can further prevent the child from affecting the blood collection operation due to struggling or involuntary movements, ensuring the smooth progress of the blood collection work;

[0047] After the blood collection is completed, the medical staff loosens the fixing nut 20, and the elastic force of the spring frame 16 pushes the sliding sleeve A17 to move upward, driving the guide block 8 and the semi-circular fixing arm 10 to separate. At the same time, the medical staff appropriately assists in moving the guide block 8 to facilitate the removal of the child's arm; clean the waste on the placement plate B6 and prepare to collect blood for the next child; considering that the elastic force of the spring frame 16 may not be able to fully drive the guide block 8 to move, the guide block 8 is made of hollow frosted plastic material, and at the same time, the medical staff needs to appropriately assist in moving the guide block 8.

[0048] Embodiment 2: Blood collection assistance for hyperactive children

[0049] Select a hyperactive child who is sensitive to noise for blood collection; the medical staff places a silent but interestingly shaped jigsaw puzzle toy in the placement plate A4 and arranges the items required for blood collection on the placement rubber pad 7 of the placement plate B6; check each component of the auxiliary device to ensure that the adjustment component 9 is flexible and the colloidal bandage 13 has good adhesion;

[0050] Let the hyperactive child sit on the chair and try to soothe his / her emotions; after placing the child's arm on the placement rubber pad 7 of the placement plate B6, the medical staff quickly holds the handle 25 and quickly adjusts the sliding sleeve B19 to make the semi-circular fixing arm 10 quickly fit the child's arm, and then quickly tightens the fixing nut 20; because the child is hyperactive, it is necessary to quickly complete the fixing operation to avoid his / her struggling from affecting the fixing effect.

[0051] Quickly paste and fix the colloidal bandage 13, use the jigsaw puzzle toy to attract the child's attention and make the child focus on the jigsaw puzzle; due to the occlusion of the light-shielding mirror 5, the child cannot see the blood collection process, reducing fear; the medical staff quickly and accurately performs the blood collection operation;

[0052] After the blood collection is completed, the medical staff loosens the fixing nut 20, and the elastic force of the spring frame 16 pushes the guide block 8 to move to both sides, assisting the medical staff to take out the child's arm; perform a simple cleaning on the auxiliary device and prepare for the next use.

[0053] It should be understood that the embodiments of the present application are not limited to the exact structures described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the embodiments of the present application is only limited by the appended claims.

[0054] The above-described embodiments only express several implementation manners of the embodiments of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the embodiments of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the embodiments of the present application.
