Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a nursing device for children's arterial puncture. Background Art

[0002] Arterial puncture is an important medical procedure, suitable for patients with severe shock who need emergency treatment, during anesthesia or surgery, and for continuous monitoring of arterial blood pressure in critically ill patients. Arterial puncture is also a necessary vital sign monitoring procedure in complex major surgeries, when there may be heavy bleeding during surgery, and in cases of open heart surgery with extracorporeal circulation. Traditional arterial puncture care requires medical staff to manually press the puncture site for a long time to stop bleeding, which not only increases the workload of medical staff, but may also cause discomfort and pain to the child. In addition, children, especially infants, have small blood vessels with poor elasticity, and are prone to struggle and non-cooperation during the puncture, which increases the difficulty and failure rate of the puncture.

[0003] At present, after arterial puncture for children, a tourniquet is generally used to press the puncture point, without the need for medical staff or family members to press. For example, the patent with publication number CN201418766Y discloses a pressurized hemostatic device for children's infusion, including an inflatable one-way valve installed on one end of the air inlet pipe, the other end of which is fixedly connected and communicated with the hemostatic airbag, and nylon buckles are respectively provided on the two ends of the winding belt fixed on the hemostatic airbag; when in use, an inflatable one-way valve is installed on one end of the air inlet pipe, the other end of which is fixedly connected and communicated with the hemostatic airbag, and nylon buckles are respectively provided on the two ends of the winding belt fixed on the hemostatic airbag. After intravenous infusion, when the needle is pulled out from the puncture point, a cotton ball is pressed on it and then on the hemostatic airbag, the winding belt is wrapped around the limb and fastened with each other through the nylon buckle, and the inflatable balloon is used to push open the inflatable one-way valve and inflate the hemostatic airbag through the air inlet pipe to pressurize the puncture point for hemostasis.

[0004] A tourniquet such as the pressurized hemostatic device provided by the above patent is used to compress the puncture point. Although the tourniquet is convenient for children to move around, the blood vessels of children, especially infants, are small and have poor elasticity. When the child's wrist moves, the tourniquet will be displaced. To prevent the tourniquet from being displaced, the tourniquet must be in tight contact with the child's wrist. However, this will increase the pressure of the tourniquet on the puncture point, affecting the hemostatic pressure effect and causing subcutaneous bruising.

[0005] In addition, the current hemostatic compression device only performs hemostatic compression on the puncture point and has a single function. Therefore, there is an urgent need to design a nursing device that is easy to wear and does not exert excessive pressure on the puncture point to ensure the safety of infusion for children. Summary of the invention

Beneficial Effects

[0017] 1. The present invention uses a combined design of a hemostatic presser and a fixing plate to accurately press the puncture point of the patient, and the fixing plate can limit the movement of the child's wrist to prevent the hemostatic presser from shaking and moving; 2. The present invention adopts the combined design of a massage head, a hydraulic rod and a hemostatic compression block. After the hemostatic compression block is used to press the puncture point, the hydraulic rod can be stretched to tilt the massage head so that the massage head can massage the skin around the puncture point. In addition, the massage head includes a plurality of massage units, and each massage unit is provided with a contact rod on one side close to the hemostatic compression block. In this way, when the hemostatic compression block is extended under the action of the positioning assembly, the side of the truncated cone-shaped moving block in the hemostatic compression block contacts the contact rod, so that each massage unit expands outward, so that the opening formed by each massage unit becomes larger, and then the hemostatic compression block passes through the opening formed by the massage unit and is located on the outside of the massage head, so that the hemostatic cotton ball can be pressed above the puncture point. In particular, since the center of the opening formed by each massage unit coincides with the center of the hemostatic compression block, when massaging the skin around the patient's puncture point, there is no need to adjust the position of the massage head again to confirm the position of the puncture point, and the operation is simple and convenient. 3. The present invention adopts the combined design of the massage head, the liquid capsule and the pressing spring. When the liquid capsule contacts the patient's skin, the elastic part is deformed by the pressure of the outer surface of the massage unit. Specifically, the elastic part switches from a cylindrical shape to a disc shape. At this time, the surface area of ​​the elastic part and the patient's skin is increased, which can further improve the cold compress effect on the patient's skin, relieve pain, and avoid swelling of the patient's skin. Fourth, the fixing part provided by the present invention is a hemispherical structure, which can further improve the cold compress effect on the patient's skin while ensuring that the pressing force of the fixing part on the patient's skin will not be reduced due to the deformation of the elastic part, and the massage effect is good; 5. The compression spring provided by the present invention can not only further increase the pressing force of the fixing part on the patient's skin, but also drive the elastic part to restore the natural state more quickly when the fixing part is not in contact with the patient's skin, so that the patient can use it more comfortably during the next massage.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The embodiment of the present invention is suitable for patients undergoing arterial puncture, especially for children. Example 1

[0025] The embodiment of the present invention provides a child arterial puncture care device, such as Figure 1-15 As shown, it includes a fixing plate 5 and a hemostatic presser arranged on the fixing plate 5, and the hemostatic presser includes a hemostatic pressing mechanism and a massage mechanism.

[0026] like Figure 1 As shown, the fixing plate 5 is provided with a U-shaped groove for sliding connection with the hemostatic presser. In actual use, the hemostatic presser can be slid to a position close to the patient's puncture point according to the position of the puncture point.

[0027] Specifically, the fixing plate 5 is provided with a plurality of Velcro strips for fixing the fixing plate 5 on the wrist or arm of the patient.

[0028] like Figure 2 and 3 As shown, the hemostatic pressing mechanism includes a positioning component 1 and a hemostatic pressing block 2 arranged at the movable end of the positioning component 1 .

[0029] The positioning assembly 1 includes a mobile base 11, a first electric telescopic rod 12, a second electric telescopic rod 13, a second rotating motor 14 and a two-stage electric telescopic rod 15, wherein a primary push rod 15a of the two-stage electric telescopic rod 15 is socketed with a fixed portion of the two-stage electric telescopic rod 15, and a secondary push rod 15b of the two-stage electric telescopic rod 15 is socketed with the primary push rod 15a.

[0030] The movable base 11 comprises a circular sliding block and an inverted "T"-shaped support frame arranged on the circular sliding block; the positioning assembly 1 is connected to the inverted "T"-shaped support frame.

[0031] In actual application, the mobile base 11 is provided with a fixer 6, and the fixer 6 includes a mounting block 61 and a locking bolt 62. Among them, the mounting block 61 is provided with a threaded hole threadedly connected with the locking bolt 62, and the bottom surface of the locking bolt 62 is provided with a circular positioning piece, so that after the mobile base 11 is moved to a position close to the patient's puncture point, the medical staff rotates the locking bolt 62 downward until the circular positioning piece at the lower end of the locking bolt 62 is in close contact with the surface of the fixing plate 5. At this time, the circular positioning piece at the lower end of the locking bolt 62 provides a downward pressure on the edge of the slide groove of the support plate, so that the bottom surface of the mobile base 11 is in close contact with the bottom surface inside the slide groove under the action of the locking bolt 62, and the friction force of the bottom surface of the mobile base 11 is increased, thereby achieving the fixation of the position of the hemostatic presser.

[0032] like Figure 4 and 6 As shown, the first electric telescopic rod 12 and the second electric telescopic rod 13 are both arranged on the mobile base 11; The bottom end of the first electric telescopic rod 12 is rotatably connected to the mobile base 11, and the push rod portion of the second electric telescopic rod 13 is connected to the bottom side of the first electric telescopic rod 12, so that the tilt angle of the first electric telescopic rod 12 can be adjusted by controlling the push rod portion of the second electric telescopic rod 13 to extend or retract, so as to adjust the height of the hemostatic compression block 2 according to the thickness of the patient's wrist; In actual use, the position of the hemostatic compression block 2 in the horizontal direction can be adjusted by controlling the push rod portion of the first electric telescopic rod 12 to extend or retract.

[0033] A second rotary motor 14 is provided at the end of the push rod portion of the first electric telescopic rod 12, and a rotary gear is provided at the output end of the second rotary motor 14, which is meshed and connected with a gear arranged at the bottom end of the two-stage electric telescopic rod 15; wherein, the bottom of the two-stage electric telescopic rod 15 is rotationally connected to the first electric telescopic rod 12; in this way, medical staff can rotate the two-stage electric telescopic rod 15 by controlling the rotation direction and number of rotations of the rotary gear on the output end of the second rotary motor 14, so that the hemostatic compression block 2 located at the end of the secondary push rod 15b of the two-stage electric telescopic rod 15 is vertically arranged above the patient's puncture point; so as to press and fix the hemostatic cotton ball.

[0034] In practical applications, the first-stage push rod 15a of the two-stage electric telescopic rod 15 can be further controlled to extend or retract to further position the hemostatic compression block 2 so that the hemostatic compression block 2 is accurately located above the puncture point; Furthermore, the secondary push rod 15b of the two-stage electric telescopic rod 15 can be controlled to extend, so that the hemostatic compression block 2 located at the end of the secondary push rod 15b extends to the outside of the massage mechanism to press the hemostatic cotton ball.

[0035] It should be noted that the two-stage electric telescopic rod 15 is a prior art, and the embodiment of the present invention does not make any improvements thereto. For example, the model of the two-stage electric telescopic rod 15 is Songli 10-1000.

[0036] The hemostatic compression block 2 includes a truncated cone-shaped moving block 21 , a compression column 22 and a plurality of fixing units 23 .

[0037] Specifically, one end of the truncated cone-shaped moving block 21 is fixedly connected to the free end of the secondary push rod 15b, and the other end is fixedly connected to the compression column 22. The compression column 22 is provided with a plurality of equally spaced fixing units 23 at one end away from the truncated cone-shaped moving block 21. The compression column 22 is used to press the hemostatic cotton ball above the puncture point, and the fixing unit 23 is used to further fix the hemostatic cotton ball to prevent the hemostatic cotton ball from moving above the puncture point. It should be noted that the embodiment of the present invention does not limit the shape of the fixing unit 23. For example, the fixing unit 23 is a cylindrical structure.

[0038] The truncated cone-shaped moving block 21 , the compression column 22 and the plurality of fixing units 23 are all made of hard materials, for example, the hard material is plastic.

[0039] The massage mechanism includes a rotating component 3 and a massage head 4 connected to the rotating component 3 .

[0040] The rotating assembly 3 includes a first rotating motor 31 , a driving gear 32 , and a gear plate 33 .

[0041] The first rotary motor 31 is fixedly arranged on the side of the primary push rod 15a, and the output rod of the first rotary motor 31 and the primary push rod 15a are arranged parallel to each other; the output end of the first rotary motor 31 is fixedly connected to the driving gear 32; The gear plate 33 is sleeved on the end of the primary push rod 15a, and the gear plate 33 is rotatably connected to the primary push rod 15a. The gear plate 33 has a side that is meshed with the driving gear 32, and the wheel plate 21c is connected to the massage head 4 on the side opposite to the driving gear 32.

[0042] In actual use, the first rotary motor 31 drives the driving gear 32 to rotate, the driving gear 32 drives the gear plate 33 to rotate, and then the gear plate 33 drives the massage head 4 to rotate, so as to massage the patient.

[0043] The massage head 4 includes a plurality of massage units 41 arranged in a circle with the truncated cone-shaped moving block 21 as the center, wherein the massage unit 41 includes a spherical massage block and a connecting rod integrally connected to the spherical massage block; in actual application, the massage unit 41 is provided with one end of the connecting rod fixedly connected to the connecting piece 43, and the plurality of massage units 41 and the connecting piece 43 form a receiving cavity; the connecting piece 43 is integrally connected to the connecting rod of the massage unit 41. The material of the massage unit 41 and the connecting piece 43 are both elastic materials, and for example, the elastic material is silicone.

[0044] Each massage unit 41 is provided with a contact rod 42 on one side close to the truncated cone-shaped moving block 21. The upper end of the contact rod 42 is fixedly connected to the massage unit 41, and the lower end is in contact with the side of the truncated cone-shaped moving block 21. Specifically, the contact rod 42 is made of a hard material, and in an exemplary embodiment, the material of the contact rod 42 is plastic. In actual applications, the contact rod 42 is fixedly connected to the massage unit 41 by gluing or snapping.

[0045] In the initial state, the hemostatic compression block 2 is located in the accommodating cavity formed by multiple massage units 41 and the connecting plate 3. At this time, the ends of each massage unit 41 close to the patient's skin are close to each other, so that the spherical massage blocks of each massage unit 41 contact each other to form a hemispherical massage head, so as to massage the skin around the patient's puncture point; it should be noted that the embodiment of the present invention does not limit the number of massage units 41. For example, the embodiment of the present invention is described by taking the massage head 4 as including four massage units 41 as an example.

[0046] In actual application, when it is necessary to press the puncture point to stop bleeding, the secondary push rod 15b is extended, and the hemostatic compression block 2 passes through the accommodating cavity of the massage unit 41 to the outside under the action of the secondary push rod 15b. In this process, the lower end of the contact rod 42 contacts the side of the truncated cone moving block 21. Under the limiting action of the side of the truncated cone moving block 21, the contact rod 42 gradually rises and moves away from the center of the truncated cone moving block 21, so that each massage unit 41 bends and deforms outward, ensuring that the hemostatic pressing block 12 is extended normally.

[0047] When it is necessary to perform hemostatic compression on the skin around the puncture point, the secondary push rod 15b retreats, driving the hemostatic compression block 2 back to the initial position. At this time, the height of the contact rod 42 gradually decreases, approaching the center of the truncated cone-shaped moving block 21, until each massage unit 41 returns to its initial shape, so as to massage the skin around the patient's puncture point.

[0048] A hydraulic rod 44 and a connecting block 45 are provided on a side of the connecting piece 43 away from the massage unit 41 . The hydraulic rod 44 and the connecting block 45 are arranged relatively on the connecting piece 43 . One end of the hydraulic rod 44 and the connecting block 45 away from the connecting piece 43 is connected to the gear plate 33 .

[0049] Specifically, the connecting block 45 is made of elastic material, for example, the connecting block 45 is made of silicone.

[0050] In actual application, medical staff can manually adjust the overall length of the hydraulic rod 44 to adjust the inclination angle of the massage head 4. In this way, the center of the massage head 4 can be moved to the side of the puncture point, so that the edge of the massage head 4 contacts the skin around the patient's puncture point, and then turn on the rotating component 3 to make the massage head 4 rotate in a circle with the gear plate 33 as the center. Since the gear plate 33 is located directly above the puncture point through the positioning component 1, the massage head 4 rotates in a circle with the patient's puncture point as the center, thereby massaging the skin around the patient's puncture point. Example 2

[0051] Based on Example 1, different from Example 1, Figure 3 , 14 As shown in FIG. 15 , each massage unit 41 provided in the embodiment of the present invention has a liquid bag 46 on its side in contact with the patient's skin, and a pressing spring 47 is provided in the liquid bag 46 .

[0052] The bladder 46 includes an elastic portion 46 a and a fixing portion 46 b .

[0053] The elastic part 46a is a cylindrical structure, and one end of the elastic part 46a away from the fixed part 46b is fixedly connected to the outer surface of the massage unit 41. The material of the elastic part 46a can be silicone, and the elastic part 46a is integrally connected to the massage unit 41. It should be noted that the embodiment of the present invention does not limit the fixed connection method of the elastic part 46a and the massage unit 41. For example, the elastic part 46a is integrally connected to the outer surface of the massage unit 41.

[0054] The fixing portion 46b is a hemispherical structure and is fixedly connected to the elastic portion 46a.

[0055] Specifically, the cavity formed by the elastic part 46a, the fixed part 46b and the outer surface of the massage unit 41 is pre-filled with cold compress material, so that the skin around the puncture point of the patient can be cold-compressed while the patient is being massaged, which can relieve pain and avoid swelling of the patient's skin.

[0056] In actual application, when the liquid capsule 46 contacts the patient's skin, the elastic portion 46a is deformed by the pressure of the outer surface of the massage unit 41. Specifically, the elastic portion 46a switches from a cylindrical shape to a disc shape. At this time, the elastic portion 46a and the patient's skin surface area are increased, thereby improving the cold compress effect on the patient while ensuring the massage intensity on the patient. Moreover, the fixing portion 46b is a hemispherical structure, which can further improve the cold compress effect on the patient's skin while ensuring that the pressing force of the fixing portion 46b on the patient's skin will not be reduced due to the deformation of the elastic portion 46a, and the massage effect is good; In addition, the pressing spring 47 can not only further increase the pressing force of the fixing portion 46b on the patient's skin, but also drive the elastic portion 46a to restore the natural state more quickly when the fixing portion 46b is not in contact with the patient's skin.

[0057] Application examples: Mr. Liu was to undergo right femoral and tibial artery bypass surgery under general anesthesia, and the needle was removed after puncturing the left radial artery; Step 1: Before removing the needle, place the fixing plate 5 under the patient's left arm, and then fix the patient's left arm with the Velcro on the fixing plate 5; Step 2: Adjust the position of the movable base 11 so that the hemostatic presser is located on a side close to the patient's puncture point; Step 3: Start the second electric telescopic rod 13 to adjust the tilt angle of the first electric telescopic rod 12, and then start the first electric push rod 11b to adjust the position of the hemostatic compression block 2 in the horizontal direction; Step 4: Start the second rotary motor 14 to make the secondary push rod 15b rotate downward; Step 5: The secondary push rod 15b extends outward until the hemostatic compression block 2 on the end of the secondary push rod 15b passes through the massage unit 41, and then the hemostatic cotton ball is inserted into the fixing unit 23 of the hemostatic compression block 2; Step 6: Adjust the secondary push rod 15b again so that the secondary push rod 15b extends outward until the hemostatic cotton ball at the end of the fixing unit 23 is secured on the puncture point; In this process, the lower end of the contact rod 42 contacts the side of the truncated cone-shaped moving block 21. Under the limiting effect of the side of the truncated cone-shaped moving block 21, the contact rod 42 gradually rises and moves away from the center of the truncated cone-shaped moving block 21, so that each massage unit 41 bends and deforms outward, ensuring that the hemostatic pressing block 12 is normally extended. Step 7: The medical staff removes the needle, and the hemostatic presser is used to focus on the patient's puncture point to prevent bleeding.

[0058] After the hemostatic compression is completed, the patient's skin around the puncture site can be massaged; including the following steps: Step 8: Start the secondary push rod 15b, so that the secondary push rod 15b retreats into the massage unit 41. In this process, the secondary push rod 15b drives the hemostatic compression block 2 back to the initial position. At this time, the height of the contact rod 42 gradually decreases, approaching the center of the truncated cone-shaped moving block 21, until each massage unit 41 returns to the initial shape, that is, each massage unit 41 is combined into a hemispherical massage head; Step 9: The medical staff manually adjusts the length of the hydraulic rod 44 so that the hemispherical massage head tilts outward with the puncture point as the center; Step 10: Turn on the first rotating motor 31. The first rotating motor 31 drives the gear plate 33 to rotate through the driving gear 32. The gear plate 33 drives the hemispherical massage head to rotate through the hydraulic rod 44. Since the hemispherical massage head rotates around the gear plate 33 and the gear plate 33 is located directly above the puncture point, the hemispherical massage head contacts the patient's skin with the patient's puncture point as the center to achieve circular massage.
