Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a sterile, reusable, adjustable pressing angle and force arterial hemostasis robotic arm. Background Technology

[0002] In the clinical diagnosis and treatment of critical care medicine, arterial catheterization is a common procedure for monitoring vital signs and carrying out related treatments. After the catheter is removed, continuous pressure needs to be applied to the puncture site to stop bleeding. At present, the mainstream hemostatic devices in clinical practice are mainly divided into two categories: wrist-type pneumatic compression devices and groin lever-type compression devices. These devices are fixed to the corresponding parts of the body by binding structures and achieve hemostasis by means of inflation or lever action. They can meet the basic hemostatic needs of different puncture sites and are widely used in clinical practice.

[0003] Most of the current mainstream compression hemostatic devices are disposable consumables that need to be discarded and replaced after a single use. Long-term use will continuously increase the medical costs for patients. In conjunction with the current medical insurance control requirements, the standards for medical expense control are becoming increasingly strict. The additional expenses brought by disposable consumables not only increase the economic burden on patients, but also do not meet the development needs of reducing costs and increasing efficiency and saving medical resources in clinical practice. Moreover, the fact that these devices cannot be reused also leads to unnecessary consumption of medical supplies. Summary of the Invention

[0004] The purpose of this invention is to provide a sterilizable, reusable, adjustable pressing angle and force arterial hemostasis robotic arm to solve the problems of existing hemostasis devices being disposable consumables, resulting in high usage costs and resource waste.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sterile, reusable, adjustable pressing angle and force arterial hemostasis robotic arm, including a mechanical positioning arm;

The pipeline connecting pipe is fixedly installed at the other port of the negative pressure switching three-way valve, and the manual negative pressure airbag is fixedly installed at the end of the pipeline connecting pipe.

[0010] Furthermore, the pressure regulating mechanism also includes an adjusting screw, a graduated sleeve, an adjusting plate, a compression spring, two limit brackets, and a pressure sensor. The adjusting screw is threaded onto the end of the fixed sleeve away from the connecting bracket. The graduated sleeve is fixedly installed on one end of the adjusting screw. The adjusting plate is installed on the other end of the adjusting screw via a bearing. The compression spring is fixedly installed between the adjusting plate and the connecting bracket. The two limit brackets are respectively fixedly installed on both sides of the cylinder wall of the fixed sleeve. The pressure sensor is embedded in the center of the end of the connecting bracket.

[0011] Furthermore, the pressure regulating mechanism also includes two limb restraint straps, a female plug and a male plug. The two limb restraint straps are respectively fixedly installed on the outer walls of both sides of the connecting frame. The female plug is fixedly installed at the end of one of the limb restraint straps, and the male plug is fixedly installed at the end of the other limb restraint strap, with the female plug and male plug engaging in a snap-fit ​​connection.

[0012] Furthermore, the mechanical positioning arm includes a ball joint universal adapter, a main column, a middle swing arm, a telescopic sleeve arm, and a universal joint. The main column is fixedly installed on the top of the ball joint universal adapter, the middle swing arm is movably hinged to the upper part of the main column, the telescopic sleeve arm is movably hinged to the upper part of the middle swing arm, and the universal joint is fixedly installed on the other end of the telescopic sleeve arm, and the universal joint is fixedly connected to the graduated sleeve.

[0013] Furthermore, a clamping base is installed at the bottom of the ball joint universal adapter, a controller is installed on the outer wall of the clamping base, a knob handle is threadedly installed at the bottom of the clamping base, and a clamping block is fixedly installed at the top of the knob handle.

[0014] Furthermore, the silicone insert has a magnetic post inside that is opposite to the magnetic pole of the positioning magnetic ring, and the silicone insert engages with the negative pressure slot, and the silicone sealing lip engages with the sealing groove.

[0015] Furthermore, both the small and large silicone pressure heads have concave surfaces that contact the patient's skin, with a micro-convex surface integrally formed at the center of the concave surface, and both the small and large silicone pressure heads are made of medical-grade silicone.

[0016] Furthermore, the outer wall of the fixed sleeve is provided with multiple scale lines, the adjusting plate is provided with a limiting groove that cooperates with the limiting frame, the limiting frame is configured as an L-shaped structure, and the connecting frame is configured as a T-shaped structure.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] (1) The present invention is equipped with a detachable small silicone pressing head and a large silicone pressing head. The pressing head achieves initial positioning and sealing by cooperating with the silicone insert, silicone sealing lip and negative pressure slot and sealing groove on the connecting frame. Then, the negative pressure is generated by the negative pressure locking mechanism to achieve final locking and fixation. The whole can be completely disassembled, disinfected and reused. It abandons the traditional disposable hemostatic consumable usage mode, effectively reduces the consumption of clinical consumables, reduces the cost of medical treatment for patients, and meets the development needs of medical cost reduction and efficiency improvement and saving medical supplies.

[0020] (2) The present invention can change the deformation of the compression spring by rotating the adjusting screw, and accurately control the pressure. The scale line on the fixed sleeve can intuitively show the adjustment stroke. The limit frame and the limit groove cooperate with each other to limit the adjustment limit and avoid excessive pressure adjustment. The pressure sensor can monitor the pressure in real time and maintain the pressure value within a safe range. This can prevent excessive pressure from causing limb ischemia in the patient, and also prevent insufficient pressure from causing wound bleeding. When used with limb limiting straps, the patient's limb can be fixed, effectively preventing limb movement from causing pressure deviation and improving the stability and safety of hemostasis.

[0021] (3) The present invention achieves rapid fixation of the whole machine through clamping base, knob handle and clamping block, which is suitable for various use scenarios such as hospital beds. The mechanical positioning arm composed of multiple joints can flexibly adjust the pressing position, height and angle, which can meet the needs of patients of different body size and different puncture sites. The controller, together with the pressure sensor, displays the pressing data in real time, which is convenient for medical staff to monitor the working condition in real time. The arterial hemostasis robotic arm can stably complete the hemostasis operation for a long time, greatly reducing the workload of medical staff. The overall structure is durable and easy to clean, and the comprehensive use value is outstanding. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] As attached Figure 1 To be continued Figure 8 As shown:

[0035] Example 1:

[0036] This invention provides a sterile, reusable, adjustable pressing angle and force arterial hemostasis robotic arm, including a mechanical positioning arm 1;

[0037] Pressure regulating mechanism 2 is fixedly installed at the end of the mechanical positioning arm 1;

[0038] The pressure regulating mechanism 2 includes a fixed sleeve 21, a connecting frame 22, a negative pressure locking mechanism 23, two negative pressure slots 213, a connecting air passage 214, four positioning magnetic rings 215, and two sealing grooves 216. The connecting frame 22 is movably inserted through the fixed sleeve 21 at the end away from the mechanical positioning arm 1. The negative pressure locking mechanism 23 is fixedly installed on one side of the outer wall of the connecting frame 22. The two negative pressure slots 213 are respectively opened on both sides of the end of the connecting frame 22. The connecting air passage 214 is opened inside the connecting frame 22 and connects the two negative pressure slots 213. The four positioning magnetic rings 215 are respectively embedded in the inner wall of each negative pressure slot 213. The two sealing grooves 216 are respectively opened on one side of the inner wall of each negative pressure slot 213.

[0039] The pressure regulating mechanism 2 is detachably mounted with a small silicone press head 3 or a large silicone press head 4 at the end away from the mechanical positioning arm 1. The two sizes of press heads can be flexibly selected according to the thickness of the patient's limb and the puncture site. The ends of the small silicone press head 3 and the large silicone press head 4 are fixedly mounted with two silicone inserts 5. The double insert design improves the assembly stability and avoids shaking under the force of a single support point. Each silicone insert 5 has an integrally formed silicone sealing lip 6. The integrally formed structure has good sealing performance, wear resistance and durability, and is easy to disinfect and clean.

[0040] The negative pressure locking mechanism 23 includes a negative pressure switching three-way valve 231, a negative pressure connecting pipe 232, a pipeline connecting pipe 233, and a manual negative pressure airbag 234. One end of the negative pressure connecting pipe 232 is connected to the negative pressure switching three-way valve 231, and the other end is fixedly installed on the outer wall of the connecting frame 22 and connected to the connecting airway 214. The pipeline connecting pipe 233 is fixedly installed at the other port of the negative pressure switching three-way valve 231. The manual negative pressure airbag 234 is fixedly installed at the end of the pipeline connecting pipe 233. It generates negative pressure by manual squeezing and does not require an external air source. Its clinical use is not limited by the site.

[0041] The silicone insert 5 has a magnetic post inside that has the opposite magnetic pole to that of the positioning magnetic ring 215. By using the principle of attraction between opposite magnetic poles, the press head can be pre-positioned, reducing assembly difficulty. The silicone insert 5 and the negative pressure slot 213 are snapped together. The snap-fit ​​structure is easy to install and remove and is not easy to jam even after repeated use. The silicone sealing lip 6 and the sealing groove 216 are snapped together to form an annular sealing barrier, which effectively maintains the negative pressure state inside the negative pressure slot 213.

[0042] Both the small silicone compression head 3 and the large silicone compression head 4 have concave surfaces that contact the patient's skin. The concave structure conforms to the contours of the human limb, improving wearing comfort and compression fit. A micro-convex surface is integrally formed at the center of the concave surface, which is used to directly compress the puncture point. Both the small silicone compression head 3 and the large silicone compression head 4 are made of medical-grade silicone, which is soft, skin-friendly, and biocompatible. It can be sterilized at high temperatures and meets the requirements for repeated use.

[0043] Working principle: In use, first, select the appropriate small silicone compression head 3 or large silicone compression head 4 according to the patient's arterial puncture location and body size. Align the silicone insert 5 at the bottom of the compression head with the negative pressure slot 213 at the end of the connecting frame 22 to complete the insertion and assembly. The silicone sealing lip 6 is inserted into the sealing groove 216 to form a sealing structure. The magnetic column inside the insert and the positioning magnetic ring 215 on the inner wall of the negative pressure slot 213 achieve initial positioning through magnetic attraction, preventing the compression head from shifting or loosening. Subsequently, repeatedly squeeze the manual negative pressure airbag 234. During the squeezing process, the air inside the manual negative pressure airbag 234 is discharged to the outside through its own one-way valve. When the airbag is released, the airbag rebounds, generating suction force, drawing the air from the negative pressure slot 213 and the connecting airway 214 into the airbag through the negative pressure connecting tube 232, the negative pressure switching three-way valve 231, and the pipeline connecting tube 233, and then discharged to the outside again with the next squeeze. Repeating this process several times gradually extracts air from the two negative pressure slots 213 and the connecting airway 214, creating a stable negative pressure environment inside. This further securely locks the silicone insert 5, significantly improving the firmness and sealing of the compression head assembly. After assembly, the overall posture of the mechanical positioning arm 1 is adjusted so that the compression head precisely fits the patient's arterial puncture wound. With the overall support of the mechanical positioning arm 1 and the pressure regulating mechanism 2, continuous and stable pressure is applied to the puncture site for hemostasis, without the need for manual hand-held compression. Once the hemostasis operation is complete, the negative pressure switching three-way valve 231 is switched to release the negative pressure state inside the negative pressure slot 213, eliminating the negative pressure locking force. The small silicone compression head 3 or the large silicone compression head 4 can then be easily removed from the negative pressure slot 213. The entire set of components can be cleaned and disinfected. After disinfection, it can be reassembled for subsequent use, achieving equipment recycling.

[0044] Example 2:

[0045] This embodiment is basically the same as the previous embodiment, except that the pressure regulating mechanism 2 also includes an adjusting screw 27, a scale sleeve 28, an adjusting plate 29, a compression spring 210, two limit frames 211, and a pressure sensor 212. The adjusting screw 27 is threadedly installed on the end of the fixed sleeve 21 away from the connecting frame 22. The scale sleeve 28 is fixedly installed on one end of the adjusting screw 27. The adjusting plate 29 is installed on the other end of the adjusting screw 27 through a bearing. The compression spring 210 is fixedly installed between the adjusting plate 29 and the connecting frame 22. The elastic element is used as the pressure output source to buffer the force and avoid hard contact that could damage the patient's limbs. The two limit frames 211 are respectively fixedly installed on both sides of the cylinder wall of the fixed sleeve 21. The pressure sensor 212 is embedded in the center of the end of the connecting frame 22.

[0046] The pressure regulating mechanism 2 also includes two limb restraint straps 24, a female plug 25 and a male plug 26. The two limb restraint straps 24 are respectively fixedly installed on the outer walls of the two sides of the connecting frame 22. The limb restraint straps 24 are made of medical elastic webbing, which is moderately elastic, breathable and skin-friendly, and resistant to disinfection. They can be reused. The female plug 25 is fixedly installed at the end of one of the limb restraint straps 24, and the male plug 26 is fixedly installed at the end of the other limb restraint strap 24. The female plug 25 and the male plug 26 are engaged.

[0047] The outer wall of the fixed sleeve 21 is provided with multiple scale lines, and the scale markings are clear, which makes it convenient for medical staff to adjust the pressure level in a standardized manner. The adjusting plate 29 is provided with a limiting groove that cooperates with the limiting frame 211. The limiting frame 211 is set with an L-shaped structure, which can limit the maximum movement range of the adjusting plate 29 and limit the ultimate compression of the compression spring 210, effectively preventing excessive pressure adjustment. The connecting frame 22 is set with a T-shaped structure, which has strong load-bearing capacity and can prevent the connecting frame 22 from detaching from the fixed sleeve 21.

[0048] Working principle: After the small silicone press head 3 or the large silicone press head 4 is installed and the negative pressure is locked, the rotating scale sleeve 28 drives the adjusting screw 27 to rotate. The adjusting screw 27 moves axially within the fixed sleeve 21 through the threaded structure, driving the adjusting plate 29 at the end to move synchronously under the guide limit of the limiting frame 211, thereby squeezing or releasing the compression spring 210. The elastic deformation of the compression spring 210 changes the overall output pressing force. By observing the corresponding position of the scale sleeve 28 on the outer wall of the fixed sleeve 21 and combining it with the scale lines, the adjustment stroke can be intuitively judged, which is convenient for medical staff. The pressure is precisely controlled; at the same time, the pressure sensor 212 monitors the force applied during the compression process in real time, continuously monitoring whether the pressure is within a safe range, avoiding excessive pressure that could cause limb ischemia or insufficient pressure that could cause wound bleeding; after the pressure adjustment is completed, the two limb restraint straps 24 are wrapped around the outside of the patient's limb, and the female plug 25 and male plug 26 at the end are engaged to assist in fixing the patient's limb, reducing positional deviation caused by limb movement. Finally, the mechanical positioning arm 1 is finely adjusted to ensure that the compression head fits tightly against the puncture wound, stably completing the arterial compression hemostasis operation.

[0049] Example 3:

[0050] This embodiment is basically the same as the previous embodiment, except that the mechanical positioning arm 1 includes a ball joint universal adapter 11, a main column 12, a middle swing arm 13, a telescopic sleeve arm 14 and a universal joint 15. The main column 12 is fixedly installed on the top of the ball joint universal adapter 11, the middle swing arm 13 is movably hinged to the upper part of the main column 12, the telescopic sleeve arm 14 is movably hinged to the upper part of the middle swing arm 13, and the universal joint 15 is fixedly installed on the other end of the telescopic sleeve arm 14, and the universal joint 15 is fixedly connected to the scale sleeve 28.

[0051] A clamping base 7 is installed at the bottom of the ball joint universal adapter 11. A controller 8 is installed on the outer wall of the clamping base 7. A knob handle 9 is threaded on the bottom of the clamping base 7. A clamping block 10 is fixedly installed on the top of the knob handle 9.

[0052] The clamping base 7 is designed with a C-shaped structure. The C-shaped opening makes it easy to clamp onto rod-shaped or plate-shaped supports, making it suitable for a wide range of applications. The top inner wall of the clamping base 7 is equipped with anti-slip teeth, which increase the friction of the contact surface and effectively prevent the whole machine from slipping and shifting. The controller 8 is electrically connected to the pressure sensor 212, ensuring stable electrical signal transmission and enabling real-time reception and analysis of pressure detection data. The ball joint universal adapter 11, main column 12, middle swing arm 13, telescopic sleeve arm 14, and universal joint 15 are all adjusted using star-shaped locking knobs. The star-shaped knobs are easy to hold, allowing for locking and unlocking operations to be completed with one hand, resulting in high adjustment efficiency.

[0053] Working principle: In use, first place the C-shaped clamping base 7 on the support of the hospital bed, operating table, etc., and turn the knob handle 9 to drive the clamping block 10 at the top to move. The clamping block 10 and the clamping base 7 cooperate to clamp the support, realizing the stable installation of the entire device. The anti-slip teeth on the inner wall of the clamping base 7 can increase the contact friction and prevent the device from sliding. After the device is fixed, operate the ball head universal adapter 11, main column 12, middle swing arm 13, telescopic sleeve arm 14 and universal joint 15. The mechanical positioning arm 1 composed of the above components can realize multi-angle and multi-directional adjustment, flexibly change the pressing height, horizontal position and tilt angle, adapt to patients of different body sizes and arterial puncture wounds in different positions. After adjustment, tighten the star-shaped locking knobs at each joint to lock the posture of the mechanical positioning arm 1 and ensure that the pressing position is always stable. Then according to For hemostasis, a small silicone compression head 3 or a large silicone compression head 4 is installed. The compression pressure is then adjusted, and the pressure sensor 212 collects pressure data in real time and transmits the electrical signal to the controller 8 for display, allowing medical staff to intuitively grasp the current compression pressure. The limb restraint strap 24 is then wrapped around the patient's limb and secured by the female plug 25 and male plug 26 to restrict the patient's limb movement. After all adjustments are completed, the device can provide long-term continuous compression hemostasis at the arterial puncture site, replacing traditional manual compression and effectively reducing the workload of medical staff. After hemostasis is completed, the limb restraint strap 24 is released, the negative pressure is released and the compression head is removed, the joints of the mechanical positioning arm 1 are unlocked, and the clamping base 7 is released. All detachable parts can be disassembled and sterilized. The entire device can be repeatedly used in clinical settings, reducing the cost and resource consumption of disposable consumables.

[0054] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
