Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a patient intraperitoneal delivery device. Background Technology

[0002] Uncompressible truncal bleeding is a leading cause of some potentially preventable deaths both in the pre-hospital and battlefield contexts. As the largest solid organ in the human body, the liver is a significant component of uncompressible truncal bleeding caused by trauma. In addressing this challenge, rapid hemostasis is crucial for saving lives. Polysaccharide-based hemostatic materials such as cellulose and starch, due to their excellent biocompatibility, biodegradability, and unique hemostatic properties, have shown great potential in the treatment of uncompressible liver bleeding.

[0003] However, since the bleeding site in the liver is located deep in the abdominal cavity, the time for emergency hemostasis is extremely urgent in battlefield environments or outdoor emergency situations. Although it is convenient for stopping bleeding from external injuries, the lack of hemostatic tools makes it impossible to quickly stop bleeding from wounds in the abdominal cavity. Even with polysaccharide-based hemostatic materials such as cellulose and starch, how to deliver the corresponding hemostatic microspheres into the bleeding site during pre-hospital intervention is a major challenge.

[0004] Therefore, we propose a patient intraperitoneal delivery device to address the problems mentioned above.

[0005] The information disclosed above in this background section is only for enhancing the understanding of the background section of this invention, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a patient intraperitoneal drug delivery device to solve the problem of how to quickly stop bleeding in intraperitoneal wounds in emergency situations, as mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides a patient intraperitoneal drug delivery device, including a balloon, and further including a connecting seat at the top of the balloon, the connecting seat being detachably connected to a telescopic tube, and a drug box inside the balloon, the drug box having an air outlet for gas from inside the balloon to enter the drug box, the air outlet, the inner cavity of the drug box, and the telescopic tube being sequentially connected along the airflow direction.

[0008] Preferably, the balloon tail is also provided with an opening, and a plug is tightly connected to the opening. The air outlet of the medicine box is connected to a one-way valve, and both the plug and the one-way valve are one-way air inlet valves.

[0009] Preferably, the telescopic tube includes an inner tube connected to the connecting seat, an outer tube sleeved on the outer wall of the inner tube, and a nozzle installed at the top of the outer tube.

[0010] Preferably, the inner wall of the connecting seat is provided with a fixing plate, the fixing plate is provided with a spring, and the top end of the spring is fixedly connected to an annular top plate.

[0011] Preferably, the annular top plate slides in conjunction with the inner wall of the connecting seat, the inner wall of the connecting seat is provided with a plurality of limiting grooves, and the outer wall of the annular top plate is provided with a plurality of limiting sliders, the limiting sliders being adapted to the limiting grooves.

[0012] Preferably, the surface of the connector is provided with several slots, and the end of the telescopic tube near the connector is provided with a connector head, which is engaged with the connector. The outer wall of the connector head is provided with several locking blocks, which are adapted to the slots.

[0013] Preferably, a connecting tube is rotatably connected inside the connecting seat. The connecting tube is divided into an insertion end and a connecting end. The insertion end is adapted to the connecting head, and the connecting end is rotatably engaged with the connecting seat.

[0014] Preferably, the inner wall of the connecting seat is provided with a rotating seat, the connecting end is provided with a rotating plate, the rotating plate is adapted to the rotating seat, the inner wall of the connecting end is connected with a plurality of connecting rods, the connecting rods are fixedly connected to rotating rods, and the circumferential side of the rotating rods is provided with a plurality of stirring rods.

[0015] Preferably, a plurality of rotating blocks are fixedly connected to the outer wall of the insertion end, and a plurality of spiral grooves are opened on the inner wall of the connector, wherein the rotating blocks are adapted to the spiral grooves.

[0016] Preferably, one end of the medicine box is provided with a threaded head, the threaded head is threadedly connected to the connecting seat, the rotating rod passes through the threaded head and is inserted into the medicine box, and the stirring rod is made of soft material.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention, by setting up a balloon, a medicine box, and a telescopic tube, first snaps the telescopic tube together with the connecting seat during use. The medicine box is pre-installed inside the balloon at the factory. The telescopic tube itself is interference-fitted and can stop at any position during extension and retraction. The telescopic tube is up to 20cm long. At this time, the tip of the telescopic tube is inserted into the bleeding site of the liver in the abdominal cavity through an external wound. By quickly pressing the balloon at the rear, the hemostatic microspheres inside are delivered to the bleeding site to achieve the purpose of rapid hemostasis. It can easily and quickly deliver hemostatic powder directly into the patient's abdominal cavity in various environments.

[0019] 2. This invention, by setting up a telescopic tube, a connector, and a connecting seat, allows the connector to be inserted into the connecting seat during use. When the connector is inserted, the annular top plate, under the action of a spring, applies an outward pushing force to the connector until the locking block reaches the bottom of the slot. The annular top plate then pushes the connector outward to tighten it, and the locking block is locked in the slot, thus preventing accidental loosening of the connector. When disassembly is required, simply press the connector inward and then rotate it in the opposite direction to remove the connector and telescopic tube. This allows the telescopic tube and the balloon to be stored separately, reducing the overall length and making it easier to carry. A puncture-resistant film can be provided at the port of the medicine box to prevent spillage.

[0020] 3. This invention, by setting up a connecting pipe, a rotating rod, and a stirring rod, allows the rotating rod to be inserted into the medicine box during installation. During insertion, the stirring rod bends until it enters the medicine box and then automatically unfolds. As the connector is inserted, the connecting pipe rotates in the opposite direction, driving the stirring rod to rotate inside the medicine box, thereby stirring the medicine in the medicine box evenly and preventing the medicine in the medicine box from settling.

[0021] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the invention will become readily apparent from the accompanying drawings and the following detailed description.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. It should be noted that the drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size. Any size is only illustrative and not limiting.

[0036] Example 1

[0037] Please see Figure 1 and Figure 4 The present invention provides a patient intraperitoneal drug delivery device, including a balloon 1, and a connecting seat 2 at the top of the balloon 1. The connecting seat 2 is detachably connected to a telescopic tube 3. The balloon 1 is also provided with a drug box 6 inside. The drug box 6 has an air outlet for gas inside the balloon 1 to enter the drug box 6. The air outlet, the inner cavity of the drug box 6 and the telescopic tube 3 are connected in sequence along the airflow direction.

[0038] The medicine box 6 is installed on the connector 2 and is located inside the balloon 1. The medicine box 6 contains hemostatic microspheres. The materials used in this device can meet the functional requirements and also meet the biosafety requirements of medical devices. The balloon 1 can apply air pressure to the medicine box 6 by pressing, thereby spraying the hemostatic microspheres in the medicine box 6 into the telescopic tube 3. After passing through the telescopic rod, the hemostatic microspheres are sprayed onto the patient's wound for precise hemostasis.

[0039] The working principle of this embodiment is as follows: When in use, the telescopic tube 3 and the connecting seat 2 are first snapped together. The medicine box 6 is installed inside the balloon 1 at the factory. The telescopic tube 3 is interference-fitted and can stop at any position during telescopic movement. The telescopic tube 3 is up to 20cm long. At this time, the top of the telescopic tube 3 is inserted into the bleeding site of the liver in the abdominal cavity through the external wound. By quickly pressing the balloon 1 behind it, the hemostatic microspheres inside are delivered to the bleeding site to achieve the purpose of rapid hemostasis.

[0040] Example 2

[0041] Reference Figure 4 The balloon 1 is also provided with an opening 11 at the tail. A block 12 is tightly connected to the opening 11. The air inlet of the medicine box 6 is connected to a one-way valve 62. Both the block 12 and the one-way valve 62 are one-way air inlet valves. The block 12 and the opening 11 can be fixedly connected or detachably connected. The connection method is not limited, as long as it can achieve the effect of sealing the opening 11.

[0042] The working principle of this embodiment is as follows: When in use, the balloon 1 is squeezed, and the air pressure inside the balloon 1 increases. As the air pressure increases, the one-way valve 62 is opened by the air pressure, and the plug 12 is tightly closed by the air pressure. The gas inside the balloon 1 rushes into the medicine box 6. The airflow carries the hemostatic microspheres in the medicine box 6 out until they are sprayed onto the patient's wound through the telescopic tube 3. When the balloon 1 is released, the balloon 1 begins to expand and the inside of the balloon 1 is in a negative pressure state. At this time, the plug 12 is sucked open by the negative pressure, and the one-way valve 62 is sucked closed by the negative pressure. At this time, external air can enter the balloon 1 until the air pressure inside the balloon 1 is balanced.

[0043] Example 3

[0044] Reference Figure 5 The telescopic tube 3 includes an inner tube 31 connected to the connecting seat 2. An outer tube 32 is sleeved on the outer wall of the inner tube 31. A nozzle 33 is installed at the top of the outer tube 32. The inner wall of the outer tube 32 is sleeved on the outer wall of the inner tube 31. The outer tube 32 and the inner tube 31 are interference-fitted. Damping allows the telescopic tube 3 to stop arbitrarily within its stroke range. The nozzle 33 is located at the top of the outer tube 32. The nozzle 33 restricts the range of hemostatic microspheres and prevents the hemostatic microspheres from splashing everywhere.

[0045] Reference Figure 3 The surface of the connector 2 is provided with several slots 21. The end of the telescopic tube 3 near the connector 2 is provided with a connector 4. The connector 4 is engaged with the connector 2. The outer wall of the connector 4 is provided with several locking blocks 41, which are adapted to the slots 21.

[0046] The connecting seat 2 is a cylindrical sleeve. The slot 21 is divided into three parts: the first part is a straight groove that passes through the connecting seat 2; the second part is a spiral groove 42 that communicates with the straight groove; and the third part is a fixed groove located at the bottom of the spiral groove 42. The connecting head 4 is a hollow cylindrical structure. The inner diameter of the connecting head 4 is the same as the inner diameter of the telescopic tube 3. The connecting head 4 and the connecting seat 2 are slidably fitted. The locking block 41 is cylindrical. The number, position, and size of the locking blocks 41 correspond to the slot 21. One end of the connecting head 4 is fixedly connected to the top end of the telescopic tube 3.

[0047] When in use, hold the telescopic tube 3 and align the various locking blocks 41 on the connector 4 with the various locking slots 21. Then insert the connector 4 into the connector seat 2. The locking blocks 41 on the connector 4 enter the spiral groove 42 through the straight groove. At this time, the locking blocks 41 drive the connector 4 to rotate until the locking blocks 41 reach the fixed groove at the bottom of the spiral groove 42. At this time, the connector 4 and the connector seat 2 are locked and fixed.

[0048] Reference Figure 3 and Figure 6 The inner wall of the connecting seat 2 is provided with a fixing plate 22, and a spring 23 is provided on the fixing plate 22. The top of the spring 23 is fixedly connected to an annular top plate 24. The annular top plate 24 slides with the inner wall of the connecting seat 2. The inner wall of the connecting seat 2 is also provided with several limiting grooves 27. The outer wall of the annular top plate 24 is also provided with several limiting sliders 28. The limiting sliders 28 are adapted to the limiting grooves 27.

[0049] The fixed plate 22 is an annular plate body. The fixed plate 22 is fixedly connected to the connecting seat 2. One end of the spring 23 is fixedly connected to the fixed plate 22, and the other end is fixedly connected to the annular top plate 24. The limiting groove 27 is a straight groove. The limiting slider 28 is a rectangular block set on the outer wall of the annular top plate 24. The limiting slider 28 slides with the limiting groove 27 to limit the rotation of the annular top plate 24. The annular top plate 24 is pushed outward under the action of the spring 23.

[0050] The working principle of this embodiment is as follows: When the connector 4 is inserted into the connector seat 2, the annular top plate 24 applies an outward pushing force to the connector 4 under the action of the spring 23 until the locking block 41 reaches the bottom of the slot 21. The annular top plate 24 pushes the connector 4 outward and the locking block 41 is locked in the slot 21, thereby preventing the connector 4 from being accidentally loosened. When disassembly is required, simply press it inward and then rotate the connector 4 in the opposite direction to remove the connector 4 and the telescopic tube 3.

[0051] Example 4

[0052] Reference Figure 4-Figure 6 The connecting seat 2 is also rotatably connected to a connecting pipe 5. The connecting pipe 5 is divided into an insertion end 51 and a connecting end 52. The insertion end 51 is adapted to the connecting head 4, and the connecting end 52 is rotatably engaged with the connecting seat 2. The inner wall of the connecting seat 2 is provided with a rotating seat 25, and the connecting end 52 is provided with a rotating plate 53. The rotating plate 53 is adapted to the rotating seat 25. Several connecting rods 54 are connected to the inner wall of the connecting end 52. The connecting rods 54 are fixedly connected to a rotating rod 55, and several stirring rods 56 are provided on the circumferential side of the rotating rod 55.

[0053] The insertion end 51 of the connecting tube 5 can be inserted into the connector 4 after the connector 4 is inserted, and coincides with the connector 4. The rotating seat 25 in the connecting base 2 is rotatably connected to the connecting tube 5. The rotating seat 25 plays a limiting role, so that the connecting tube 5 can only rotate and cannot move. The connecting end 52 of the connecting tube 5 is fixedly connected to an annular rotating plate 53. A limiting plate 26 is also fixedly provided in the connecting base 2. A certain space is left between the rotating seat 25 and the limiting plate 26. The rotating plate 53 is located in this space. When the connecting tube 5 rotates, the rotating plate 53 rotates between the rotating seat 25 and the limiting plate 26. The movable plate 53 serves as a limit and seal. The inner wall of the connecting pipe 5 is fixed to the rotating rod 55 by multiple connecting rods 54. The rotating rod 55 is located on the axis of the connecting pipe 5. Multiple soft stirring rods 56 are provided on the circumferential side of the rotating rod 55, which can deform and automatically reset. The rotating rod 55 can be directly inserted into the inside of the medicine box 6, so that when the connecting pipe 5 rotates, the medicine in the medicine box 6 is stirred and mixed by the stirring rods 56 to prevent the medicine from settling and causing uneven spraying. A puncturable film can be provided at the port of the medicine box 6 to prevent the medicine from spilling.

[0054] Reference Figure 5 A number of rotating blocks 57 are fixedly connected to the outer wall of the insertion end 51. A number of spiral grooves 42 are opened on the inner wall of the connector 4. The rotating blocks 57 are adapted to the spiral grooves 42. The rotation direction of the spiral grooves 42 is opposite to the rotation direction of the slot 21. When the connector 4 is inserted, when the slot 41 is aligned with the slot 21, the rotating blocks 57 are aligned with each spiral groove 42. As the connector 4 is inserted, each rotating block 57 enters each spiral groove 42. The spiral grooves 42 will drive the rotating blocks 57 to drive the connecting tube 5 to rotate. When the connecting tube 5 rotates, it drives the rotating rod 55 to rotate, so that the medicine box 6 can be stirred by the stirring rod 56.

[0055] Reference Figure 5 One end of the medicine box 6 is provided with a threaded head 61, which is threadedly connected to the connecting seat 2. The rotating rod 55 passes through the threaded head 61 and is inserted into the medicine box 6. The medicine box 6 can be disassembled by setting the threaded head 61. The size of the medicine box 6 is smaller than the size of the opening 11 of the balloon 1. Therefore, after the medicine in the medicine box 6 is used up, the plug 12 can be removed, the medicine box 6 can be taken out from the opening 11 of the balloon 1, the medicine can be replenished, and then it can be reinstalled and fixed.

[0056] The working principle of this embodiment is as follows: When installing the medicine box 6, the rotating rod 55 is inserted into the medicine box 6. During the insertion process, the stirring rod 56 bends until it enters the medicine box 6 and then automatically unfolds. The medicine box 6 is threadedly connected to the connecting seat 2 through the threaded head 61. Then, the plug 12 is installed to seal the balloon 1. The connector 4 of the telescopic tube 3 is inserted into the connecting seat 2. The snap-fit ​​block 41 on the connector 4 enters the slot 21. During the insertion process, the connector 4 continuously squeezes the annular top plate 24 and compresses the spring 23 until the snap-fit ​​block 41 reaches the bottom of the slot 21. At this time, the spring 23 passes through... The annular top plate 24 pushes the connector 4 outward slightly, so that the connector 4 is locked and fixed with the connector seat 2. During the insertion of the connector 4, the rotating block 57 of the connecting tube 5 enters the spiral groove 42. As the connector 4 is inserted, the connecting tube 5 rotates in the opposite direction, driving the stirring rod 56 to rotate in the medicine box 6, thereby stirring the medicine in the medicine box 6 evenly. At this time, the outer tube 32 of the telescopic tube 3 is pulled outward, and the nozzle 33 at the top of the outer tube 32 is sent into the bleeding site of the liver in the abdominal cavity through the external wound. Then, the hemostatic microspheres inside the balloon 1 are sent to the bleeding site by quickly pressing the balloon 1 at the rear.
