Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a compression hemostasis device for nursing. Background Art

[0002] In clinical nursing work in hospitals, patients often need to undergo blood tests or intravenous injections. After blood drawing or intravenous injection, the needle puncture site will bleed, and medical staff will ask patients to press the puncture site with a sterilized cotton swab or a sterilized cotton ball for a period of time to prevent bleeding. Pressing to stop bleeding is relatively easy for most patients, but for patients with severe illnesses or who cannot take care of themselves, they cannot complete the above-mentioned pressing process by themselves, which requires medical staff to press the puncture point for a long time; in the process of pressing the patient, subcutaneous congestion or bleeding on the skin may occur due to improper pressing force or a relatively short pressing time, which undoubtedly increases the burden on medical staff and causes certain harm to patients. Therefore, it is necessary to use a compression hemostasis device to continuously press and stop bleeding on the patient to reduce the burden on medical staff and improve the overall nursing experience of patients.

The rotating disk 32 rotates to cooperate with the arc groove 35 and the first guide block 36 to drive the clamping block 30 to move inside the fixed disk 31, and the fixed disk 31 is used to move out of the clamping groove 34, thereby releasing the fixed state between the first pressing piece 12, the second pressing piece 13 and the third pressing piece 14. Because the size of the fixed disk 31 fixed to the rotating rod 28 is smaller than the fixed disk 31 fixed to the first rod 24, that is, when rotating, the fixed state between the first pressing piece 12 and the second pressing piece 13 is first released, and at this time, the second pressing piece 13 and the third pressing piece 14 are still fixed. In the subsequent pressing process of hemostasis, the first pressing piece 12 is compressed and collected in the second pressing piece 13 to form a larger pressing range, thereby completing the initial adjustment and forming a preliminary increase in the pressing range;

[0096] When it is necessary to further expand the range, that is, continue to rotate the second knob 26. During the rotation of the second knob 26, the first set rod 24 and the rotating rod 28 still rotate synchronously. At this time, since the arc groove 35 inside the bottom rotating disk 32 and the block 30 have formed motion interference, during the continuous rotation of the rotating rod 28, the built-in cavity 49 is squeezed by the second spring 50 and received into the first embedding groove 47, which will not affect the subsequent continuous rotation of the first set rod 24, so that the engaging state between the block 30 and the groove 34 at the middle position can continue to be controlled to be released, and then the combination between the second pressing piece 13 and the third pressing piece 14 is completed during the pressing process, so as to further expand the pressing range to meet the needs of different patients.

[0097] Embodiment 4:

[0098] This embodiment aims to address the problem that the compression hemostasis device for nursing in the prior art is difficult to buffer the sudden increase in pressure at the beginning of pressing and cannot maintain uniform pressure distribution when pressing to stop bleeding.

[0099] A buffer assembly 22 is installed between the third pressing piece 14 and the lifting block 9. The buffer assembly 22 includes four connecting rods 37 rotatably connected to the upper surface of the third pressing piece 14 in a rectangular shape. The bottom end of the connecting rod 37 passes through and extends to the top of the lifting block 9 and is rotatably connected to the second guide block 40. A guide groove 41 is provided at the inner top of the lifting block 9 corresponding to the position of the second guide block 40. A guide rod 38 fixed in the guide groove 41 passes through the interior of the second guide block 40. The outer layer of the guide rod 38 is sleeved with a buffer spring 39 fixed to one side of the second guide block 40. A buffer is formed by the buffer spring 39, and at the same time, a more stable and uniform pressure is applied to the three pressing pieces, so as to perform a better pressing and hemostasis operation on the patient.

[0100] During the process of pressing and stopping bleeding, the three pressing pieces move upward after contacting the skin due to the reaction force. During the movement, the third pressing piece 14 moves toward the internal position of the positioning hole 6. During the movement of the third pressing piece 14, the connecting rod 37 is driven to move. The movement of the connecting rod 37 drives the second guide block 40 to move along the guide rod 38 toward the outside of the guide groove 41. During the movement of the second guide block 40, it is buffered by the rebound force of the buffer spring 39. At the same time, a more stable and uniform pressure is applied to the third pressing piece 14, thereby forming a more uniform pressing and stopping bleeding effect on the patient's skin and avoiding excessive local pressure differences.

[0101] Working process and principle of the present invention:

[0102] Step 1: When fixing, the device is sleeved on the outside of the patient's limb, and then the third knob 46 is rotated to drive the bidirectional screw 43 to rotate, and the two-way screw 43 rotates to cooperate with the screw sleeve to drive the limit block 42 to move relatively, thereby pulling the protective strap 2 to tighten, so as to match the patient's limb size to form a preliminary fixation, and then filling the air bag 3 with gas through the ventilation tube. After the air bag 3 is filled with gas, it expands, so as to form a close fit with the patient's limb and reduce the discomfort caused by long-term fixation;

[0103] Step 2: When performing a compression hemostasis operation on a patient, the initial position of the lifting block 9 is located at the bottom end of the first lead screw 10. First, the first knob 15 is rotated to drive the rotating shaft 16 to rotate. The rotating shaft 16 rotates in coordination with the first bevel gear 17 and the second bevel gear 18 to drive the first lead screw 10 to rotate. The rotation of the first lead screw 10 drives the moving block 8 to rise, and the lifting of the moving block 8 drives the three pressing plates to rise.

[0104] At the same time, the first lead screw 10 rotates to drive the connecting rod 19 to rotate, and the connecting rod 19 rotates to drive the second lead screw 20 to rotate, thereby driving the dust cover 5 to descend and separate from the mounting plate 1, and then the patient can be fixed with the device to perform the next step of pressing and stopping bleeding;

[0105] Step 3: After the preparatory work is completed, the first knob 15 is used to control the positioning hole 6 to descend, and the positioning hole 6 descends to drive the three pressing pieces to descend. When the initial state is pressed, the first pressing piece 12 is used to press the wound to stop bleeding. When the patient needs to expand the pressing range due to physical requirements or wound requirements;

[0106] The second knob 26 is rotated to drive the second rod 25 to rotate, and the second rod 25 is rotated to drive the first rod 24 and the rotating rod 28 to rotate. The first rod 24 and the rotating rod 28 are driven to rotate the rotating disk 32 during the rotation process. The rotating disk 32 rotates to cooperate with the arc groove 35 and the first guide block 36 to drive the clamping block 30 to move inside the fixed disk 31, and the fixed disk 31 is used to move out of the clamping groove 34, thereby releasing the fixed state between the first pressing piece 12, the second pressing piece 13 and the third pressing piece 14. Because the size of the fixed disk 31 fixed to the rotating rod 28 is smaller than the fixed disk 31 fixed to the first rod 24, that is, when rotating, the fixed state between the first pressing piece 12 and the second pressing piece 13 is first released, and at this time, the second pressing piece 13 and the third pressing piece 14 are still fixed. In the subsequent pressing process of hemostasis, the first pressing piece 12 is compressed and collected in the second pressing piece 13 to form a larger pressing range, thereby completing the initial adjustment and forming a preliminary increase in the pressing range;

[0107] When the range needs to be further expanded, that is, the second knob 26 is continuously rotated. During the rotation of the second knob 26, the first set rod 24 and the rotating rod 28 still rotate synchronously. At this time, since the arc groove 35 inside the bottom rotating disk 32 and the clamping block 30 have formed motion interference, during the continuous rotation of the rotating rod 28, the built-in cavity 49 is squeezed by the second spring 50 and received into the first embedded groove 47, which will not affect the subsequent continuous rotation of the first set rod 24, so that the clamping state between the clamping block 30 and the clamping groove 34 at the middle position can be continuously controlled to be released, and then the combination between the second pressing piece 13 and the third pressing piece 14 is completed during the pressing process, so as to further expand the pressing range, thereby meeting the needs of different patients;

[0108] Step 4: During the process of pressing and stopping bleeding, the three pressing pieces move upward after contacting the skin due to the reaction force. During the movement, the third pressing piece 14 moves toward the internal position of the positioning hole 6. During the movement of the third pressing piece 14, the connecting rod 37 is driven to move. The movement of the connecting rod 37 drives the second guide block 40 to move along the guide rod 38 toward the outside of the guide groove 41. During the movement of the second guide block 40, it is buffered by the rebound force of the buffer spring 39. At the same time, a more stable and uniform pressure is applied to the third pressing piece 14, thereby forming a more uniform pressing and stopping bleeding effect on the patient's skin and avoiding excessive local pressure differences.

[0109] In summary, the dust cover 5 pressing piece is protected daily to avoid contamination. When in use, the protective strap 2 is used in conjunction with the airbag 3 to form a stable and tight fixation between the patient's limbs. Then, the elastic mechanism 21 is used to adjust the state of the first pressing piece 12, the second pressing piece 13 and the third pressing piece 14 to meet the needs of the patient. The first knob 15 is used to control the lifting and lowering of the lifting block 9. During the pressing process, the buffer component 22 is used to reduce the sudden increase in pressure, while maintaining the uniform distribution of subsequent pressure, thereby improving the patient's overall nursing experience.

[0110] 1. Compared with the prior art, the present invention is provided with an elastic mechanism, and the first pressing plate, the second pressing plate and the third pressing plate cooperate with each other to press and stop bleeding. Since the size of the puncture wound of the patient and the elasticity of the individual skin and tissue are different, it can be adjusted according to the needs of different patients. The state between the card block and the card slot is controlled by the second knob, and then the state between the three pressing plates is controlled, that is, when pressing, the first pressing plate moves into the second pressing plate, and the second pressing plate moves into the third pressing plate. In this way, according to the patient's condition, the pressure on the patient is dispersed, the overall pressing range is increased, the efficiency of overall compression and hemostasis is improved, and the overall nursing experience of the patient is improved;

[0111] 2. The present invention is provided with a buffer component. When the patient is pressed by three pressing plates, the third pressing plate moves toward the inside of the lifting block, and the connecting rod cooperates with the guide rod and the guide block to move toward the inside and outside of the guide groove. During the movement of the guide block, the rebound force of the buffer spring forms a buffer to reduce the impact of the sudden pressure increase on the patient. At the same time, due to the effect of the rebound force of the buffer spring, the pressing plate forms a more uniform and continuous pressure on the skin to reduce the occurrence of excessive pressure differences on the local skin.

[0112] 3. The present invention is provided with a dust cover, and the pressing sheet is located at the bottom of the support frame during daily storage. The dust cover is used to protect the pressing sheet from dust, and further protects the pressing sheet from contamination, thereby ensuring the cleanliness of the pressing sheet. When compression hemostasis is required for the patient, the lifting block is raised by controlling the first knob, and the connection rod is rotated at the same time. The rotation of the connection rod drives the second screw to rotate, thereby releasing the fixation of the dust cover, and then the dust cover can be removed, providing a good preparatory state for subsequent compression hemostasis.

[0113] In the present invention, an air bag is arranged on the inner side of the protective bandage. When the device is fixed at the wound position of the patient, the device is sleeved on the outer side of the patient's limb, and the movement of the two limit plates is controlled by the second knob, thereby driving the protective bandage to move to match the patient's limb size. After the initial fixation, gas is filled into the air bag through the air hole to cause the air bag to expand. The expanded air bag forms a tighter fit with the patient's limb, while reducing the discomfort caused by long-term binding.
