Description

A pressure infusion bag for cerebrovascular intervention and its usage method Technical Field

[0001] This invention belongs to the field of pressurized infusion bag technology, and specifically relates to a pressurized infusion bag for cerebrovascular intervention and its usage method. Background Technology

[0002] In interventional cerebrovascular procedures, arterial pressure infusion lines are a key measure to prevent intraoperative thrombosis and reduce complications. Traditional pressure infusion bags are usually manually pressurized, requiring nurses to pressurize each bag individually, which is time-consuming and lacks precise pressure control, easily leading to prolonged operation time, increased nursing workload, and low patient satisfaction.

[0003] Utility model CN223464292U discloses an alarm-type pressurized infusion bag for interventional procedures, including a pressurized bag body. One end of the pressurized bag body is connected to a connecting hose, and the other end of the connecting hose is equipped with an inflation bladder and a three-way valve. The other end of the pressurized bag body is equipped with a connector, and the outer end of the connector is equipped with a pressure gauge. The pressure gauge rotates with the pointer by a ring rotating component at the rear end of the pressure gauge. Under the interaction between the positioning columns, when the pressurized bag is inflated and the pressure reaches 300 mmHg, the switch is turned on, and the buzzer does not sound. During continuous irrigation during the procedure, the pressure drops. When the pressure drops to 250 mmHg, the first contact switch and the third contact switch are connected, and the buzzer sounds an alarm, indicating that the pressurized infusion bag needs to be pressurized. After pressurization, the first contact switch and the third contact switch are disconnected, the buzzer circuit is broken, and the buzzer alarm stops. This realizes the pressure alarm function of the entire infusion bag. It mainly achieves the alarm when the pressure is insufficient by the ring rotating component rotating with the pointer.

[0004] The utility model disclosed in announcement number CN222708781U is a heated and pressurized infusion bag. The key technical features include an outer bag body, an inflation mechanism, and a heating mechanism. The outer bag body has an inner cavity for placing the infusion bag. The inflation mechanism is connected to the outer bag body and is used to inflate the inner cavity with gas. The heating mechanism is detachably connected to the outer bag body and is used to heat the inner cavity. The heated and pressurized infusion bag mainly separates the pressurized gas from the liquid inside the infusion bag through the inner and outer cavities to avoid direct contact.

[0005] Utility model announcement CN214859982U discloses an alarm device for a pressurized infusion bag. Key technical features include an infusion bag body, with a pressure gauge and a pressurizing balloon connected to the bottom of the body via a first and second air inlet pipe. The bottom of the infusion bag body also has a first outlet pipe communicating with it. Inside the first outlet pipe is a second outlet pipe. A through hole is provided on the side wall of the second outlet pipe near the connection point with the first outlet pipe. A float is provided inside the second outlet pipe. The inner diameter of the second outlet pipe near the first outlet pipe is larger than the inner diameter of the outlet end of the second outlet pipe. The diameter of the float is equal to the inner diameter of the outlet end of the second outlet pipe. An alarm sensor is provided on the outer wall of the second outlet pipe. Its structure emphasizes reminding the patient when the infusion is about to be completed and preventing air from entering the patient's body.

[0006] The above-mentioned issues highlight the cumbersome operation when multiple infusion bags are used in parallel, the inability to achieve synchronized pressurization and automatic pressure regulation, and the potential safety risks.

[0007] Therefore, there is an urgent need for an infusion bag system that can achieve rapid, synchronous, and automatic pressurization to improve surgical efficiency and nursing quality. Summary of the Invention

[0008] The purpose of this invention is to address the shortcomings of the prior art by providing a pressurized infusion bag for cerebrovascular intervention and its usage method, thereby achieving rapid, synchronous, and automatic pressurization of the infusion bag.

The clamping assembly (8) is located on the corresponding side wall grooves of the stepped groove (603). The clamping assembly (8) includes a clamping plate (801) and a buffer spring (802). One end of the buffer spring (802) is fixed on the wall groove body, and the other end is sleeved on the clamping plate. Under the action of the buffer spring, the pressure bag located in the middle is clamped and pressed. The clamping plate is also equipped with an adjustment assembly (9) for adjusting the clamping force. The main infusion tube (4) is also equipped with a pressure gauge (2) for real-time pressure monitoring. The pressure gauge (2) is connected to the adjustment assembly (9) and the winding tube (7) by electrical control signal. During installation, the pressure bag (1) passes through the trapezoidal groove (602), the stepped groove (603), and the clamping assembly (8) in sequence and is fixed on the winding tube (7). Under the detection of the pressure gauge (2), it is collected and pressurized in real time by the action of the adjustment assembly (9) and the winding tube (7).

[0010] The take-up tube (7) includes a rotating shaft (701) and a take-up gear (703) fixedly connected to one end thereto, and the take-up gear (703) is engaged with the transmission motor (10) for transmission.

[0011] The rotating shaft is also equipped with a fixed cover, which is installed and fixed by a slot opened on the rotating shaft, while the pressure bag is fixed between the two.

[0012] The tee (3) has a main channel (301) and a secondary channel (302). The main channel (301) is sealed to the main infusion tube (4), and the secondary channel (302) is connected to the secondary infusion tube (5). Both the main channel (301) and the secondary channel (302) are equipped with sealing caps (304) on their outer sides and are sealed by rubber sealing gaskets (303).

[0013] The adjustment assembly (9) includes a threaded shaft (901), an electrical connection block (903) symmetrically sleeved on the threaded shaft (901), and a rotary knob (902) fixed at both ends of the threaded shaft (901) for adjusting the position of the electrical connection block (903). The rotary knob (902) rotates to adjust the threaded shaft (901) and drives the electrical connection block (903) to rotate. The threaded shaft (901) is rotatably mounted on the winding shell (601), and the rotary knob (902) is placed on the outer surface of the winding shell (601). One end of the electrical connection block (903) is limited between the two clamping plates (801), and the other end is electrically connected to the drive motor (10) and controls the start and stop of the drive motor (10).

[0014] The pressure bag (1) is also equipped with a buzzer and indicator light.

[0015] A method for using a pressure infusion bag for cerebrovascular intervention includes the following steps: (1) connecting multiple pressure bags (1) in parallel via a three-way valve (3); (2) initially storing and pressurizing the pressure bags (1) via a winding tube (7); (3) using a clamping assembly (8) and an adjusting assembly (9) for automatic pressure feedback control; (4) during infusion, automatically adjusting the pressure via a drive motor (10) to maintain a constant pressure; (5) after infusion, alerting medical staff via an indicator light and a buzzer.

[0016] In step (2), the top of the pressure bag (1) passes through the trapezoidal groove (602) and the stepped groove (603) and is fixed to the take-up tube (7). Then, the take-up tube (7) is rotated, and the liquid in the pressure bag (1) moves upward and pushes the clamping plate (801) to move to both sides. At the same time, the take-up tube (7) collects the blank part of the pressure bag (1) and pressurizes the pressure bag (1) in conjunction with the clamping assembly (8). When the pressure reaches the pressure threshold set by the pressure gauge (2), the take-up tube (7) stops, and the rotary knob (902) is rotated to move the electrical connection block (903) to the center. When the electrical connection contact point of the electrical connection block (903) separates from the edge of the clamping plate (801), the indicator light goes out, and the standard position is reached. After connecting the multiple pressure bags (1) to be used to the tee (3) in this way, the installation work is completed.

[0017] In step (4), as the liquid in the pressure bag (1) decreases, the pressure decreases accordingly. The clamping plate (801) moves towards the center. When its edge contacts the electrical connection block (903), the drive motor (10) is controlled to rotate, and the winding tube (7) rotates to retract the pressure bag (1). The pressure inside the bag increases. This process is repeated continuously, and the pressure inside the pressure bag (1) remains constant.

[0018] The beneficial effects of the present invention are: (1) The present invention discloses a pressure infusion bag for cerebrovascular intervention and its usage method.

By setting up the pressure assembly and the multi-channel three-way structure, multiple bags can be pressurized synchronously and quickly, which greatly shortens the traditional manual pressurization time and significantly improves the efficiency of the operation. By setting up the winding tube and the clamping assembly, it is beneficial to realize the automatic storage and pressure maintenance of the pressure bags, forming a closed-loop control of "pressure reduction-automatic pressure replenishment", which effectively maintains the pressure stability and realizes the rapid, synchronous and automatic pressurization of the infusion bags, reducing the operational burden of nursing staff.

[0019] (2) By setting up an electrical connection block and a pressure feedback mechanism, it is beneficial to achieve precise automatic adjustment of pressure, reduce the risk of arterial blood reflux and thrombosis caused by pressure fluctuations, and improve the safety of surgery; by setting up a sealed three-way valve and a parallel structure, it is beneficial to flexibly expand the infusion path, while ensuring the continuity of perfusion, reducing the occurrence of infection and air embolism, and improving the satisfaction of patients and medical staff.

Detailed Implementation

[0021] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0022] The present invention provides a pressurized infusion bag for cerebrovascular intervention, as shown in Figures 1 to 6.

[0023] A pressure infusion bag for cerebrovascular intervention includes multiple sets of pressure bags (1), a main infusion tube (4), and a secondary infusion tube (5) connected to the main infusion tube (4) via a tee (3). The secondary infusion tube (5) connects multiple pressure bags (1) arranged in parallel via a corresponding tee (3). Each set of pressure bags is also provided with a pressure assembly (6) and a clamping assembly (8). The pressure assembly (6) includes a winding shell (601), a winding tube (7) rotatably disposed on the winding shell (601), and a trapezoidal groove (602) and a stepped groove (603) opened in the winding shell (601). The trapezoidal groove (602) is located at the end of the stepped groove (603) and gradually widens from the inside to the outside. The clamping assembly (8) is correspondingly installed in the stepped groove (603). On the corresponding two side wall grooves; the clamping assembly (8) includes a clamping plate (801) and a buffer spring (802), and one end of the buffer spring (802) is fixed on the wall groove body, and the other end is sleeved on the clamping plate and pressurizes the pressure bag located in the middle under the action of the buffer spring. The clamping plate is also equipped with an adjustment assembly (9) for adjusting the clamping force; the main infusion tube (4) is also equipped with a pressure gauge (2) for real-time pressure monitoring, and the pressure gauge (2) is connected to the adjustment assembly (9) and the winding tube (7) by electrical control signal; during installation, the pressure bag (1) passes through the trapezoidal groove (602), the stepped groove (603), and the clamping assembly (8) in sequence and is fixed on the winding tube (7). Under the detection of the pressure gauge (2), it is stored and pressurized in real time by the action of the adjustment assembly (9) and the winding tube (7).

[0024] The take-up tube (7) includes a rotating shaft (701) and a take-up gear (703) fixedly connected to one end thereto, and the take-up gear (703) is engaged with the transmission motor (10) for transmission.

[0025] The rotating shaft is also equipped with a fixed cover, which is installed and fixed by a slot opened on the rotating shaft, while the pressure bag is fixed between the two.

[0026] The tee (3) has a main channel (301) and a secondary channel (302). The main channel (301) is sealed to the main infusion tube (4), and the secondary channel (302) is connected to the secondary infusion tube (5). Both the main channel (301) and the secondary channel (302) are equipped with sealing caps (304) on their outer sides and are sealed by rubber sealing gaskets (303).

[0027] The adjustment component (9) includes a threaded shaft (901), an electrical connection block (903) symmetrically sleeved on the threaded shaft (901), and a rotary knob (902) fixed at both ends of the threaded shaft (901) for adjusting the position of the electrical connection block (903). The rotary knob (902) rotates to adjust the threaded shaft (901) and drives the electrical connection block (903) to rotate. In this embodiment, the threaded shaft (901) adopts a mirror threaded shaft structure.

[0028] The threaded shaft (901) is rotatably mounted on the winding housing (601), and the rotary knob (902) is placed on the outer surface of the winding housing (601). One end of the electrical connection block (903) is limited between the two clamping plates (801), and the other end is electrically connected to the drive motor (10) and controls the start and stop of the drive motor (10).

[0029] The pressure bag (1) is also equipped with a buzzer and indicator light.

[0030] A method for using a pressure infusion bag for cerebrovascular intervention includes the following steps: (1) connecting multiple pressure bags (1) in parallel via a three-way valve (3); (2) initially storing and pressurizing the pressure bags (1) via a winding tube (7); (3) using a clamping assembly (8) and an adjusting assembly (9) for automatic pressure feedback control; (4) during infusion, automatically adjusting the pressure via a drive motor (10) to maintain a constant pressure; (5) after infusion, alerting medical staff via an indicator light and a buzzer.

[0031] In step (2), the top of the pressure bag (1) passes through the trapezoidal groove (602) and the stepped groove (603) and is fixed to the take-up tube (7). Then, the take-up tube (7) is rotated, and the liquid in the pressure bag (1) moves upward and pushes the clamping plate (801) to move to both sides. At the same time, the take-up tube (7) collects the blank part of the pressure bag (1) and pressurizes the pressure bag (1) in conjunction with the clamping assembly (8). When the pressure reaches the pressure threshold set by the pressure gauge (2), the take-up tube (7) stops, and the rotary knob (902) is rotated to move the electrical connection block (903) to the center. When the electrical connection contact point of the electrical connection block (903) separates from the edge of the clamping plate (801), the indicator light goes out, and the standard position is reached. After connecting the multiple pressure bags (1) to be used to the tee (3) in this way, the installation work is completed.

[0032] In step (4), as the liquid in the pressure bag (1) decreases, the pressure decreases accordingly. The clamping plate (801) moves towards the center. When its edge contacts the electrical connection block (903), the drive motor (10) is controlled to rotate, and the winding tube (7) rotates to retract the pressure bag (1). The pressure inside the bag increases. This process is repeated continuously, and the pressure inside the pressure bag (1) remains constant.

[0033] The following detailed description is provided with reference to a specific embodiment: In this embodiment, a drive motor 10 and an automatic pressure adjustment system are used to achieve rapid, synchronous pressurization and constant pressure of the pressure bag. Specifically, the pressure bag 1 is stored through a winding tube 7, and automatic pressure feedback control is achieved in conjunction with the clamping assembly 8 and the adjustment assembly 9. This solves the problem that the pressure bags 1 need to be installed sequentially during use, ensuring the continuity of injection and reducing the probability of local swelling and infection. The drive motor 10 is an existing structure, and its specific structure and connection method will not be described in detail in this embodiment.

[0034] As shown in Figure 2, multiple pressurized bags 1 to be used are connected in parallel through a T-junction 3. The T-junction 3 has a main channel 301 and a secondary channel 302. Both the main channel 301 and the secondary channel 302 are equipped with sealing caps 304 and rubber sealing gaskets 303 on their outer sides to ensure the sealing of the connection.

[0035] As shown in Figures 3 and 4, the take-up tube 7 includes a rotating shaft 701. One end of the rotating shaft 701 is fixedly connected to a take-up gear 703, which meshes with a drive motor 10. The drive motor 10 controls the rotation of the take-up tube 7. A fixing cover 702 is installed on the outside of the rotating shaft 701. The fixing cover 702 is installed on the rotating shaft 701 through a slot. The top of the pressure bag 1 is fixed between the rotating shaft 701 and the fixing cover 702. When the rotating shaft 701 rotates, it can take in the pressure bag 1, thereby increasing the pressure inside the bag.

[0036] The pressurizing component 6 is equipped with a buzzer and an indicator light. After the infusion of multiple bags is completed, the above steps cause the winding tube 7 to fail to retract again, and the clamping component 8 no longer separates under the action of the winding tube 7. At this time, it is determined that the liquid in the pressurizing bag 1 is completely injected. At this time, the indicator light is constantly on. When multiple pressurizing bags 1 are finished, the buzzer will work because the buzzer and the indicator light are connected in series.

[0037] As shown in Figure 5, the clamping assembly 8 includes a clamping plate 801 and a buffer spring 802. The edge of the clamping plate 801 is made of metal. When the electrical connection block 903 contacts the edge of the clamping plate 801, the electrical signal is connected and the drive motor 10 starts.

[0038] When the drive motor 10 rotates one unit, the take-up tube 7 rotates one unit, causing the pressure bag 1 to be partially retracted, and the pressure inside the pressure bag 1 will increase.

[0039] As shown in Figure 6, the adjustment component 9 includes a mirror threaded shaft 901, which has a mirror threaded groove. Rotary knobs 902 are provided at both ends of the mirror threaded shaft 901. The mirror threaded shaft 901 is mounted on the winding housing 601, and the rotary knobs 902 are located on the surface of the winding housing 601. Electrical connection blocks 903 are mounted at both ends of the clamping plate 801.

[0040] When the pressure threshold set by pressure gauge 2 is reached, the winding tube 7 stops. At this time, rotating the rotary knob 902 moves the electrical connection block 903 to the center. When the electrical connection contact point of the electrical connection block 903 separates from the edge of the clamping plate 801, the indicator light goes out, indicating that the standard position has been reached.

[0041] The working principle of this invention is as follows: the automatic start of the drive motor 10 is achieved by using the connection of electrical signals and the conversion of pressure, forming a positive feedback relationship of "pressure decrease - electrical signal connection - drive motor start - pressure increase". At the same time, multiple pressure bags 1 can be used synchronously by using the multi-pipe connection of the three-way valve 3.

[0042] The specific steps for using the pressure infusion bag for cerebrovascular intervention are as follows: S1: Connect multiple pressure bags 1 to be used in parallel through a T-connector 3. The pressure bag 1 is installed at the main channel 301 through the main infusion tube 4 and at the secondary channel 302 through the auxiliary infusion tube 5. The end of the secondary channel 302 is connected to the injection port. When it is necessary to temporarily add items, open the sealing cap 304 at the farthest end and insert the tip of the auxiliary infusion tube 5 of the newly added pressure bag 1 into the rubber sealing gasket 303 to achieve convenient adjustment of the number of pressure bags 1.

[0043] S2: Secure the top of the pressure bag 1 through the trapezoidal groove 602 and the stepped groove 603 to the take-up tube 7. Rotate the take-up tube 7, and the liquid bag of the pressure bag 1 will move upward, pushing the clamping plate 801 to both sides. At the same time, the take-up tube 7 will collect the empty part of the pressure bag 1 and pressurize the pressure bag 1 in conjunction with the clamping assembly 8. When the pressure threshold set by the pressure gauge 2 is reached, the take-up tube 7 will stop. Rotate the rotary knob 902 to move the electrical connection block 903 to the center. When the electrical connection contact point of the electrical connection block 903 separates from the edge of the clamping plate 801, the indicator light will go out, indicating that the standard position has been reached. Connect the multiple pressure bags 1 to the tee 3 according to the above steps to complete the installation.

[0044] S3: As the arterial injection continues, the liquid in the pressure bag 1 decreases, and its pressure decreases accordingly. The clamping plate 801 moves towards the center, and its edge contacts the electrical connection block 903. Since the other end of the electrical connection block 903 is electrically connected to the drive motor 10, the drive motor 10 is controlled to rotate one unit, and the winding tube 7 rotates one unit, so that the pressure bag 1 is partially retracted, and the pressure in the pressure bag 1 increases. This process is repeated continuously so that the pressure in the pressure bag 1 remains constant.

[0045] S4: After the infusion of multiple bags is completed, the above steps cause the take-up tube 7 to fail to retract again, and the clamping component 8 no longer separates under the action of the take-up tube 7. At this time, it is determined that the liquid in the pressure bag 1 is completely injected, and the indicator light stays on. When multiple pressure bags 1 are finished, the buzzer will sound because it is connected in series with the indicator light, reminding medical staff to take action.

The method of using a pressure infusion bag for cerebrovascular intervention according to claim 7, characterized in that: In step (2), the top of the pressure bag (1) passes through the trapezoidal groove (602) and the stepped groove (603) and is fixed to the take-up tube (7). Then, the take-up tube (7) is rotated, and the liquid in the pressure bag (1) moves upward and pushes the clamping plate (801) to move to both sides. At the same time, the take-up tube (7) collects the blank part of the pressure bag (1) and pressurizes the pressure bag (1) in conjunction with the clamping assembly (8). When the pressure reaches the pressure threshold set by the pressure gauge (2), the take-up tube (7) stops, and the rotary knob (902) is rotated to move the electrical connection block (903) to the center. When the electrical connection contact point of the electrical connection block (903) separates from the edge of the clamping plate (801), the indicator light goes out, and the standard position is reached. After connecting the multiple pressure bags (1) to be used to the tee (3) in this way, the installation work is completed.

9. The method of using a pressure infusion bag for cerebrovascular intervention according to claim 7, characterized in that: In step (4), as the liquid in the pressure bag (1) decreases, the pressure decreases accordingly. The clamping plate (801) moves towards the center. When its edge contacts the electrical connection block (903), the drive motor (10) is controlled to rotate, and the winding tube (7) rotates to retract the pressure bag (1). The pressure inside the bag increases. This process is repeated continuously, and the pressure inside the pressure bag (1) remains constant.
