Description

Technical Field

[0001] This invention relates to the field of medical thermal insulation technology, and in particular to a medical thermal insulation device with constant temperature function. Background Technology

[0002] When primary and secondary schools organize free physical examinations for students, some students are afraid of blood collection and have difficulty controlling their arms to keep them steady. This is especially true for primary school students, who are younger and have a stronger fear of blood collection. This makes it easy for the blood collection needle to detach from the vacuum blood collection tube during the blood collection process, resulting in blood collection failure. In addition, when using the existing vacuum blood collection tube, it is necessary to take the vacuum blood collection tube out of the constant temperature incubator and then put it back into the incubator, which is a cumbersome operation. Summary of the Invention

[0003] To overcome the shortcomings of existing blood collection methods where students are afraid of blood collection, have difficulty controlling their arms to maintain stability, and are prone to detaching the blood collection needle from the vacuum blood collection tube, leading to blood collection failure, this invention provides a medical warming device with a constant temperature function.

[0004] Technical Solution: A medical warming device with constant temperature function includes a warming box and a lid; the lid is connected to the warming box; it also includes a support frame, vacuum blood collection tubes, blood collection needles, tube caps, connecting caps, connecting rings, protective films, and a shaking component; the support frame is installed inside the warming box; several vacuum blood collection tubes are placed on the support frame; a blood collection needle is installed above the lid; each vacuum blood collection tube is connected to a tube cap, which is detachably connected to the support frame; each tube cap is provided with a puncture membrane; an ice pack is installed inside the warming box to maintain the low temperature inside the box; the blood collection needle is provided with an interlocking part, which... The device has several semi-circular grooves on its top; several connecting caps are connected to the top cover, with the center point of each connecting cap aligned with the center point of the corresponding tube cap; each connecting cap has a fitting cylinder containing several semi-cylinders; each connecting cap has a connecting ring; each connecting ring has a protective membrane to prevent blood leakage from the vacuum blood collection tube; each protective membrane contacts the outer side of the adjacent puncture membrane via a sponge, which absorbs any leaked blood; the incubator and support frame are connected to a shaking assembly to ensure thorough mixing of the blood sample with the anticoagulant in the vacuum blood collection tube.

[0005] To further explain, the rocking assembly includes a push rod and baffles; two baffles are slidably connected to the insulated box; a push rod is rotatably connected to each of the two baffles; the push rods are fixedly connected to the support frame.

[0006] To further clarify, the insulated box is equipped with a carrying strap.

[0007] To further explain, a crank handle is fixed to the push rod located on the right side.

[0008] Further explanation: It also includes a rotating assembly, which comprises a mainspring, a first rotating ring, a second rotating ring, and a retaining plate; a mainspring is fixedly attached to the underside of each connecting cover; the other end of each mainspring is fixedly attached to an adjacent connecting ring; the connecting ring is rotatably connected to the connecting cover; a first rotating ring is fixedly attached to the underside of each connecting ring, the first rotating ring being a clockwise spiral wedge shape; a second rotating ring is fixedly attached to each tube cap, the second rotating ring being a counterclockwise spiral wedge shape; several retaining plates are fixedly attached to the upper side of each protective film; each retaining plate is slidably connected to an adjacent connecting ring.

[0009] To further explain, the insulated box is equipped with two observation windows, each made of transparent plastic material; the support frame is also made of transparent plastic material.

[0010] To further explain, each pipe cover is provided with two first fitting blocks, each first fitting block is trapezoidal and the inclined surface faces forward; each connecting cover is provided with two second fitting blocks, each second fitting block is trapezoidal and the inclined surface faces forward.

[0011] To further explain, it also includes a guide tube; a guide tube is fixed to the underside of the puncture membrane on each tube cap; the other end of each guide tube is aligned with the inner wall of the adjacent vacuum blood collection tube.

[0012] To further clarify, the guide tube is made of flexible plastic.

[0013] To further explain, it also includes cleaning discs; several cleaning discs are fixed inside each guide tube.

[0014] The beneficial effects of this invention are: by integrating the vacuum blood collection tube into the insulated box, there is no need to remove the vacuum blood collection tube and then put it back into the insulated box when performing blood collection operations, thus improving the convenience of blood collection.

[0015] By limiting the blood collection needle with the connecting cap, the blood collection needle cannot deviate, which improves the protection of the puncture membrane and protective membrane, and avoids the problem that the blood collection needle may easily detach from the vacuum blood collection tube during blood collection, leading to blood collection failure.

[0016] The blood sample leaking from the puncture membrane is wiped by rotating the sponge, which increases the contact area between the sponge and the blood sample, making it easier for the blood sample to adhere to the sponge and for medical staff to observe the blood adhering to the sponge.

[0017] By allowing blood to flow along the guide tube to the inner wall of the vacuum blood collection tube, and then flowing down the inner wall of the vacuum blood collection tube to the bottom of the vacuum blood collection tube, the blood is buffered, improving the subsequent testing effect of the blood sample.

Detailed Implementation

[0025] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0026] Example 1

[0027] like Figures 1-6 As shown, a medical insulation device with constant temperature function includes an insulation box 1 and a lid 2; the lid 2 is connected to the insulation box 1.

[0028] It also includes a support frame 3, vacuum blood collection tubes 4, blood collection needles 5, tube caps 6, connecting caps 7, connecting rings 8, protective films 9, and a shaking assembly; the support frame 3 is installed inside the insulated box 1; several vacuum blood collection tubes 4 are placed on the support frame 3; blood collection needles 5 are installed above the caps 2; each vacuum blood collection tube 4 is connected to a tube cap 6, which is snapped into the support frame 3; each tube cap 6 is provided with a puncture membrane 6001; ice packs are installed inside the insulated box 1; the blood collection needles 5 are provided with a fitting part 5001, and the fitting part 5001 is... The cover 2 is provided with several semi-circular grooves; several connecting covers 7 are connected to the cover 2, and the center point of the connecting cover 7 is directly opposite the center point of the corresponding tube cover 6; each connecting cover 7 is provided with a fitting cylinder 7002, and each fitting cylinder 7002 is provided with several semi-cylinders; each connecting cover 7 is connected with a connecting ring 8; each connecting ring 8 is connected with a protective film 9; each protective film 9 is in contact with the outer side of the adjacent puncture film 6001 through a sponge 9001; the insulated box 1 and the support frame 3 are jointly connected with a shaking component.

[0029] The rocking assembly includes a push rod 101 and a baffle 102; two symmetrical baffles 102 are slidably connected to the heat preservation box 1; each of the two baffles 102 is rotatably connected to a push rod 101 on the opposite side; the push rod 101 is fixedly connected to the support frame 3.

[0030] The insulated box 1 is fixed with a shoulder strap; making it convenient for medical staff to carry the insulated box 1.

[0031] A crank is fixed to the push rod 101 on the right side; this makes it easy for medical staff to turn the push rod 101.

[0032] It also includes a rotating assembly, which includes a spring 201, a first rotating ring 202, a second rotating ring 203, and a retaining plate 204; a spring 201 is fixedly attached to the lower side of each connecting cover 7; the other end of each spring 201 is fixedly attached to the adjacent connecting ring 8; the connecting ring 8 is rotatably connected to the connecting cover 7; a first rotating ring 202 is fixedly attached to the lower side of each connecting ring 8, and the first rotating ring 202 is in a clockwise spiral wedge shape; a second rotating ring 203 is fixedly attached to each tube cover 6, and the second rotating ring 203 is in a counterclockwise spiral wedge shape; several retaining plates 204 are fixedly attached to the upper side of each protective film 9; each retaining plate 204 is slidably connected to the adjacent connecting ring 8.

[0033] Before blood is drawn from a student, medical staff first carry the insulated box 1 on their back using a shoulder strap. Then, they insert one end of the blood collection needle 5 into a blood vessel in the student's arm and pass the other end of the needle 5 through the corresponding connecting cap 7. This causes the needle 5 to squeeze and pierce the protective membrane 9, sponge 9001, and puncture membrane 6001, allowing it to enter the vacuum blood collection tube 4 to begin the blood collection operation. After obtaining the required blood sample, the medical staff removes the needle 5 from the vacuum blood collection tube 4. The protective membrane 9 and puncture membrane 6001 gradually return to their original state after being released from the pressure of the needle 5 (the protective membrane 9 and puncture membrane 6001 are existing technologies and will not be elaborated on here). The puncture membrane 6001 seals the vacuum blood collection tube 4, and the protective membrane 9 protects the puncture membrane 6001, preventing external dust and impurities from directly contacting it and causing it to age and fail, thus compromising the vacuum blood collection process. Blood flows out of tube 4; subsequently, blood is collected from other students in sequence using the same method. Thus, by integrating the vacuum blood collection tube 4 into the insulated box 1, it is not necessary to remove the vacuum blood collection tube 4 and then reinsert it into the insulated box 1 during blood collection, improving the convenience of blood collection. Furthermore, compared to existing methods that require removing the vacuum blood collection tube 4 from the insulated box 1 before blood collection, this invention keeps the vacuum blood collection tube 4 within the insulated box 1 throughout the blood collection process, maintaining a constant temperature and allowing the blood to cool rapidly after entering the tube, thus preserving the original state of the blood sample. It should be noted that, unlike blood collection in hospital pharynx departments, when medical staff collect blood from students on campus, they need to carry the insulated box 1 and the vacuum blood collection tube 4 to the blood collection point. Therefore, integrating the vacuum blood collection tube 4 into the insulated box 1 also facilitates the carrying of blood collection tools.

[0034] Considering that students may have difficulty maintaining arm stability during blood collection using the lancet 5, causing the end of the lancet 5 inserted into the vacuum blood collection tube 4 to deviate, which may compress the puncture membrane 6001 and the protective membrane 9, making them more susceptible to damage and losing their protective effect on the collected blood, after the lancet 5 is inserted into the vacuum blood collection tube 4, the fitting part 5001 is embedded into the fitting cylinder 7002, and the semi-circular groove of the fitting part 5001 is embedded into the semi-cylinder of the fitting cylinder 7002. The connecting cover 7 limits the lancet 5, preventing it from deviating, thus improving the protection of the puncture membrane 6001 and the protective membrane 9, and avoiding the problem of the lancet 5 easily detaching from the vacuum blood collection tube 4 during blood collection, leading to blood collection failure.

[0035] After blood collection, medical staff hold both push rods 101 and push them downwards. Push rods 101, via baffle 102, cause support frame 3 to move downwards until baffle 102 can no longer move downwards. Simultaneously, the downward movement of support frame 3 causes vacuum blood collection tube 4 and cap 6 to move downwards, separating the puncture membrane 6001 and protective membrane 9. After baffle 102 can no longer move downwards, using a left-to-right viewpoint, the staff holds the crank on the right push rod 101 and rotates it back and forth slightly. Support frame 3 and vacuum blood collection tube 4 follow the slight rotation of push rod 101. The blood sample inside vacuum blood collection tube 4 shakes with the rotation, gradually mixing the blood sample with the anticoagulant inside, preventing blood coagulation and ensuring subsequent blood sample retrieval. This invention achieves batch mixing of blood sample and anticoagulant inside vacuum blood collection tube 4, which, compared to existing shaking methods, avoids blood... Excessive shaking can cause hemolysis. To improve blood protection, medical staff use push rod 101 to move the vacuum blood collection tube 4 upwards and reset it, allowing the puncture membrane 6001 and protective membrane 9 to re-attach. Then, the incubator 1 and vacuum blood collection tube 4 are moved to the laboratory. Note that a manual locking structure is provided between the baffle 102 and the incubator 1 (the manual locking structure is existing technology and is not shown in the attached diagram; its specific working principle will not be elaborated upon). The manual locking structure fixes the baffle 102 to the incubator 1, thus stabilizing the push rod 101, support frame 3, vacuum blood collection tube 4, and tube cap 6. Note that during the process of moving the incubator 1 and vacuum blood collection tube 4 to the laboratory, if the blood sample in the vacuum blood collection tube 4 leaks from the puncture membrane 6001 due to shaking of the incubator 1 and vacuum blood collection tube 4, the sponge 9001 absorbs the leaked blood sample to prevent leakage and contamination of the incubator 1 and other vacuum blood collection tubes 4.

[0036] It is important to note that after moving the incubator 1 and vacuum blood collection tube 4 to the laboratory, medical personnel should first remove the connecting cap 7 from the cap 2. The connecting cap 7 will move the connecting ring 8, protective film 9, and sponge 9001 upwards to the outside. At this time, medical personnel should observe whether there is blood adhering to the sponge 9001. If there is blood, it indicates that the blood sample in the vacuum blood collection tube 4 has leaked, and this blood sample should not be used to avoid affecting the accuracy of the test results. In other words, there is no need to remove the blood sample from the vacuum blood collection tube 4. If there is no blood, the staff will insert the needle on the liquid collection device into the vacuum blood collection tube 4 and then remove the blood sample from the vacuum blood collection tube 4 into a glass test tube for subsequent analysis. After the medical personnel have removed all the blood samples from the vacuum blood collection tubes 4, the staff will open the cap 2, remove the vacuum blood collection tube 4 with the leaked blood sample, and finally take the incubator 1 for cleaning in preparation for future use.

[0037] Considering that during the process of absorbing leaked blood samples by the sponge 9001, if the leakage is small, the blood sample absorbed by the sponge 9001 may not be obvious, and given the large number of vacuum blood collection tubes 4, it is easy to overlook them manually, resulting in the leaked vacuum blood collection tubes 4 being used in subsequent analysis operations. Therefore, during the initial insertion of the connecting cap 7 into the cap 2, the sponge 9001 will first contact the puncture membrane 6001, and the first rotating ring 202 will contact the second rotating ring 203. As the connecting cap 7 continues to move downwards and is installed in place, the retaining plate 204 will slide within the connecting ring 8, and the first rotating ring 202 will continue to move downwards. Since the first rotating ring 202 is a clockwise spiral wedge shape and the second rotating ring 203 is a counterclockwise spiral wedge shape... Therefore, as the first rotating ring 202 continues to move downwards, it will press against the second rotating ring 203, causing both to rotate and compress the spring 201. The rotation of the first rotating ring 202 simultaneously drives the locking plate 204, connecting ring 8, protective film 9, and sponge 9001 to rotate. Later, when the connecting cover 7 is pulled upwards to observe whether blood is adsorbed on the sponge 9001, the first rotating ring 202 and the second rotating ring 203 disengage. At this time, the spring 201 gradually returns to its original state, causing the locking plate 204, connecting ring 8, protective film 9, and sponge 9001 to gradually rotate. It should be noted that at this time, the locking plate 204 will slide within the connecting ring 8 and will not move upwards. This ensures that the protective membrane 9 and sponge 9001 remain in constant contact with and rotate against the puncture membrane 6001. The rotating sponge 9001 then wipes away any leaked blood sample from the puncture membrane 6001, increasing the contact area between the sponge 9001 and the blood sample, making it easier for the blood sample to adhere to the sponge 9001 and facilitating observation by medical personnel. Subsequently, after the first rotating ring 202 completely disengages from the second rotating ring 203, the sponge 9001 stops rotating, and the clamping plate 204 moves upward as the connecting ring 8 continues to move upward, thus moving the sponge 9001 upward to the outside. Medical personnel can then observe whether there is any blood on the sponge 9001. It is worth noting that within the vacuum blood collection tube 4... During the mixing of blood samples and anticoagulant, as the vacuum blood collection tube 4 and cap 6 move downwards, the first rotating ring 202 and the second rotating ring 203 disengage from each other, the spring 201 gradually returns to its original state, and the first rotating ring 202, protective film 9, and sponge 9001 rotate. Subsequently, after the mixing of blood samples and anticoagulant in the vacuum blood collection tube 4 is completed, i.e., the push rod 101 is pushed upwards to reset the shaken vacuum blood collection tube 4 and cap 6, the second rotating ring 203 re-presses the first rotating ring 202, causing the spring 201 and the first rotating ring 202 to rotate, so that the protective film 9 and sponge 9001 return to the rotating state, so that the sponge 9001 can subsequently absorb the leaked blood sample.

[0038] The incubator 1 is equipped with two symmetrical observation windows 1001, each made of transparent plastic. The support frame 3 is also made of transparent plastic. When the vacuum blood collection tube 4 is placed on the support frame 3, the side of the vacuum blood collection tube 4 with the label should face the observation window 1001. This allows staff to observe the label on the vacuum blood collection tube 4 through the observation window 1001 before using the liquid extractor to remove the blood sample from the vacuum blood collection tube 4. This helps medical staff know which blood sample number is being used, facilitating the subsequent classification of the blood samples.

[0039] Each tube cap 6 is provided with two left-right symmetrical first fitting blocks 6002, each first fitting block 6002 is trapezoidal and the inclined surface faces forward; each connecting cap 7 is provided with two left-right symmetrical second fitting blocks 7001, each second fitting block 7001 is trapezoidal and the inclined surface faces forward; the tube cap 6 and connecting cap 7 are positioned by the first fitting blocks 6002 and the second fitting blocks 7001, thereby realizing the positioning of the first rotating ring 202 and the second rotating ring 203, avoiding the positional deviation between the first rotating ring 202 and the second rotating ring 203, which would cause the second rotating ring 203 to rotate the first rotating ring 202 by too small an angle, affecting the wiping effect of the sponge 9001 on the leaked blood sample.

[0040] Example 2

[0041] Based on Example 1, such as Figure 4 As shown, it also includes a guide tube 301; a guide tube 301 is fixed to the lower side of the puncture membrane 6001 on each tube cap 6; the other end of each guide tube 301 is aligned with the inner wall of the adjacent vacuum blood collection tube 4.

[0042] The guide tube 301 is made of flexible plastic tube.

[0043] Considering that after the blood enters the vacuum blood collection tube 4 along the blood collection needle 5, the blood will fall directly to the bottom of the vacuum blood collection tube 4, causing the red blood cells in the blood to collide with each other, resulting in red blood cell rupture and hemolysis, after the blood collection needle 5 is inserted into the vacuum blood collection tube 4, the blood is made to flow along the guide tube 301 to the inner wall of the vacuum blood collection tube 4, and then the blood is made to flow down along the inner wall of the vacuum blood collection tube 4 to the bottom of the vacuum blood collection tube 4, so as to buffer the blood and improve the subsequent detection effect of the blood sample;

[0044] It was also considered that when the needle on the liquid collection device is inserted into the vacuum blood collection tube 4, the guide tube 301 would interfere with the downward movement of the needle. Therefore, by setting the guide tube 301 as a flexible plastic tube, when the needle is inserted into the vacuum blood collection tube 4, the needle will squeeze the guide tube 301, causing the guide tube 301 to deform and gradually become vertical, so that the needle can move downward to the blood sample and then collect the blood sample.

[0045] It also includes cleaning plates 302; several cleaning plates 302 are fixedly connected inside each guide tube 301.

[0046] Considering that the needle of the liquid collection device will be inserted into the blood sample, the blood sample will adhere to the surface of the needle during the process of removing the needle from the vacuum blood collection tube 4. This will cause the blood adhering to the surface of the needle to drip down onto the cap 2 after the needle is removed from the vacuum blood collection tube 4, causing unnecessary contamination. Wiping the adhering blood with the puncture membrane 6001 can easily cause blood to seep out. Therefore, during the upward movement of the needle, the cleaning plate 302 is used to clean the blood adhering to the surface of the needle to prevent blood from dripping onto the cap 2.

[0047] It should be understood that the above description is for illustrative purposes only and is not intended to limit the invention. Those skilled in the art will understand that variations of the invention are included within the scope of the claims herein.
