Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of injection molding manufacturing, in particular to an integrated injection molding equipment for anesthetic drug delivery tracheal tube. BACKGROUND

[0002] With the development of society, medical equipment manufacturing is developing towards high precision and integration. The anesthetic drug delivery tracheal tube, as a key auxiliary device in anesthesia surgery, needs to have both airway ventilation and drug delivery functions. Its structure includes a main pipe body, an air bag, a drug pipe, a trachea and a connector.

[0003] The anesthetic drug delivery tracheal tube has a main pipe for gas delivery, and a hollow air bag and a drug pipe integrated on the outer wall of the main pipe. Since the air bag has a hollow structure, an inner wall mold and an outer wall mold need to be provided during the injection molding process to form the hollow chamber of the air bag. After each component is molded, the air bag and the drug pipe are assembled to the outer wall of the main pipe one by one by manual or mechanical means. However, this batch production mode requires multiple handling and transportation of each molded component, increasing the complexity of the production process. Moreover, the components are easily exposed to the external environment during handling and subsequent assembly, which is difficult to meet the stringent cleanliness requirements of medical devices. Therefore, there is an urgent need for an equipment that can realize integrated injection molding of the main pipe, air bag and drug pipe. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides an integrated injection molding equipment for anesthetic drug delivery tracheal tube. The equipment drives multiple molds through multiple linear slides on the gantry to integrally complete the injection molding of the air bag, main pipe, branch pipe and connector on the same equipment, thereby solving the problems of complex process and easy pollution raised in the background art.

[0005] To achieve the above purpose, the present application realizes the following technical scheme: an integrated injection molding equipment for anesthetic drug delivery tracheal tube, comprising a gantry, a horizontal linear slide is installed on the chassis of the gantry, a vertical linear slide one is installed on the left vertical rod of the gantry, a bidirectional linear slide one is installed on the sliding table of the vertical linear slide one, a bidirectional linear slide two is fixedly installed on the outer wall of the base of the bidirectional linear slide one, a vertical linear slide two is installed on the right vertical rod of the gantry, a bidirectional linear slide three is installed on the sliding table of the vertical linear slide two, a bidirectional linear slide four and a vertical linear slide three are installed on the cross beam of the gantry, the vertical linear slide three is installed vertically on the top of the bidirectional linear slide four, a support mold is slidably installed on the bidirectional linear slide one, an air bag mold is slidably installed on the bidirectional linear slide two, during the air bag injection stage, the air bag mold is wrapped around the outer wall of the support mold, and then molten material is injected to form the air bag; The bidirectional linear slide rail is slidably mounted with a main pipe mold. During the main pipe injection stage, the main pipe mold wraps around the support mold, and then the molten material is injected to form the main pipe and the drug and gas channels. The bidirectional linear slide rail four is slidably mounted with a branch pipe mold, and the longitudinal linear slide rail three is slidably mounted with a joint mold. During the joint and branch pipe injection stage, the branch pipe mold is wrapped around the outer wall of the support mold, and the joint mold is located on top of the branch pipe mold. Then, the molten material is injected to form the joint, medicine tube and air tube.

[0006] The support mold includes two main support rods mounted on two slides of a bidirectional linear slide rail. A drug channel support rod and an air channel support rod are fixedly connected to both sides of the main support rod. A baffle tube is fixedly connected to the outer wall of the drug channel support rod and the air channel support rod. An airbag support block is slidably connected to the outer wall of the baffle tube.

[0007] A connecting block is fixedly connected to the outer wall of the baffle tube, and an installation cavity is opened on the inner wall of the airbag support block. A spring is installed inside the installation cavity, and the top of the spring is connected to the connecting block.

[0008] The airbag mold includes two mold blanks mounted on two slides of a bidirectional linear slide rail. The inner wall of the mold blank has an airbag forming groove and an injection hole.

[0009] In the above technical solution, the airbag is encapsulated and injection molded by the cooperation of the support mold and the airbag mold. At the same time, the spring and the airbag support block are adapted to adjust the position of the airbag after molding, which provides a basis for the subsequent connection between the main tube and the airbag.

[0010] Based on the above, the main tube mold includes two mold blanks mounted on two slides of the bidirectional linear slide rail. The end of the inner wall of the mold blank is fixedly connected to an end support rod, and the inner wall of the mold blank is provided with a main tube forming groove.

[0011] Two top support rods are fixedly connected to the inner wall of the main forming groove, and the mold blank two has an injection hole two inside.

[0012] The top of the main support rod, the drug channel support rod, and the mold blank two are all fixedly connected with a connector, and the bottom of the end support rod one and the top support rod are both provided with a connector corresponding to the connector.

[0013] In the above technical solution, the main tube is encapsulated and injection molded through the main tube mold. The end support rod 1, the top support rod and the joint of the support mold are precisely connected. At the same time, the pre-formed airbag and the main tube are directly connected in the mold, without the need for subsequent manual assembly, thus realizing the integrated molding of the main tube and the airbag.

[0014] Based on the above, the branch pipe mold includes two mold blanks three mounted on two slides of the bidirectional linear slide rail four. The mold blank three has two branch pipe forming grooves inside, an injection hole three inside, and an injection hole four communicating with the joint forming groove inside.

[0015] The joint mold includes a joint support block installed on the three slides of the longitudinal linear slide rail. The joint support block has an end support rod two inside, and the top of the mold blank three has a joint forming groove.

[0016] The bottom of the second end support rod is provided with a mating interface corresponding to the mating joint.

[0017] In the above technical solutions, the injection molding of the medicine tube, air tube and connector is achieved by cooperating with the branch tube mold and the connector mold, realizing the integrated molding of the entire cannulation process.

[0018] This invention provides an integrated injection molding device for endotracheal intubation and administration of anesthetic drugs. It has the following beneficial effects: By setting up an airbag mold and a support mold, during use, the first bidirectional slide rail drives the two main support rods to merge, and the second bidirectional slide rail drives the two mold blanks to merge and wrap around the main support rods. The baffle tube extends from the top by a spring and injects material into the mold blank, forming an airbag between the airbag forming groove and the support block. Then, the transverse slide rail moves the first longitudinal slide rail to the two mold blanks, so that the main support rod is located between the main tube forming groove. The third bidirectional slide rail merges the two mold blanks and wraps around the main support rod. The second longitudinal slide rail controls its downward movement, so that the top of the main support rod aligns with the end support rod, and the top of the air passage and medicine passage support rod aligns with the top support rod. Then, the first longitudinal slide rail drives the first bidirectional slide rail and the main support rod to move downward, and the baffle tube retracts relative to the airbag support block, exposing the top and end of the airbag. The main tube is formed in the molding groove, and then the material is injected through the second injection hole to form the main tube and internal air and drug channels inside the airbag. Finally, the transverse slide rail brings back the main support rod, and the bidirectional slide rail two moves the airbag mold away to complete the demolding of the outer wall. The top joint is fixed with a clamp. The bidirectional slide rail one moves the support mold away so that the axis of the air and drug channel support rod is located on the outer wall of the main tube. The longitudinal slide rail one drives it to move down, and the main support rod is demolded from the main tube. The airbag support block is released through the gap between the airbag and the main tube. After the support block is demolded, the electric heating ring melts the lower end of the airbag, and the two main support rods move outward to expand the main tube wall and fit and connect with the inner wall of the airbag. Finally, the airbag support block is pulled out, which can realize the one-piece injection molding of the airbag and the main tube, improve the efficiency of the manufacturing process, and reduce the risk of pollution.

[0021] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] The current production of endotracheal tubes for anesthesia requires multiple independent processes. First, the main tube, cuff, branch tube, and connector are injected separately, and then they are assembled by pasting or hot-melting through manual transport. This process is not only complicated, but also prone to contamination due to contact with air during transport, which affects the safety of medical use.

[0023] Therefore, in view of the above-mentioned problems, the present invention discloses an integrated injection molding device for endotracheal intubation for anesthesia, with reference to... Figures 2-6As shown, the system includes a gantry frame 1, a transverse linear slide rail 2 mounted on the base of the gantry frame 1, a longitudinal linear slide rail 3 mounted on the left upright of the gantry frame 1, a bidirectional linear slide rail 4 mounted on the slide table of the longitudinal linear slide rail 3, and a bidirectional linear slide rail 5 fixedly mounted on the outer wall of the base of the bidirectional linear slide rail 4. Both the bidirectional linear slide rail 4 and the bidirectional linear slide rail 5 are double-slide table structures. A support mold 11 is slidably mounted on the bidirectional linear slide rail 4 to provide internal support during injection. An airbag mold 10 is slidably mounted on the bidirectional linear slide rail 25. During the airbag injection stage, the bidirectional linear slide rail 25 drives the two mold blanks 101 to... The airbag mold 10 is moved to enclose the outer wall of the support mold 11, forming a closed airbag forming cavity. Molten material is then injected into the cavity through the injection hole 102. After the molten material cools, the airbag is formed. The support mold 11 includes two main support rods 111 mounted on two slides of the bidirectional linear slide rail 4. The main support rods 111 provide central support for the main tube forming. Drug channel support rods 112 and air channel support rods 113 are fixedly connected to both sides of the main support rods 111 to ensure the drug and air channels are formed. A baffle tube 117 is fixedly connected to the outer wall of the drug channel support rod 112 and the air channel support rod 113. The baffle tube 117 is used during airbag injection. The airbag support block 114 is slidably connected to the outer wall of the baffle tube 117, providing top support. The airbag support block 114 is perfectly aligned with the inner wall of the airbag, providing precise inner wall support for airbag formation and ensuring uniform airbag thickness. A connecting block 115 is fixedly connected to the outer wall of the baffle tube 117, used to fix one end of the spring 116. An installation cavity is formed on the inner wall of the airbag support block 114, and the spring 116 is installed inside the cavity. The top of the spring 116 is connected to the connecting block 115. Initially, the spring 116 is in a slightly compressed state, using its elasticity to push the airbag support block 114 upwards, thus providing top support. The top of 14 fits against the inner wall of the airbag forming groove 103 of the mold blank 101, ensuring that the top of the airbag is sealed after forming. The airbag mold 10 includes two mold blanks 101 mounted on two slides of the bidirectional linear slide rail 2 5. The opposite surfaces of the two mold blanks 101 are provided with semi-circular arc grooves. After the mold is closed, a complete circular airbag forming groove 103 is formed. The inner wall of the mold blank 101 is provided with the airbag forming groove 103. The arc surface of the airbag forming groove 103 is consistent with the shape of the outer wall of the airbag. The inner wall of the mold blank 101 is provided with the injection hole 102. During injection, the molten material enters the airbag forming groove 103 at a uniform speed through the injection hole 102.

[0024] refer to Figures 7-11As shown, a longitudinal linear slide rail 2 6 is installed on the right upright of the gantry frame 1. A bidirectional linear slide rail 3 7 is installed on the slide platform of the longitudinal linear slide rail 2 6. A main tube mold 12 is slidably installed on the bidirectional linear slide rail 3 7. The main tube mold 12 is used for injection molding the main tube body of the cannula, and simultaneously molding the drug passage and gas passage inside the main tube. During the main tube injection stage, the transverse linear slide rail 2 first drives the support mold 11 to move directly below the main tube mold 12. Then, the bidirectional linear slide rail 3 7 drives the two mold blanks 2 121 to move towards each other, so that... The main tube mold 12 encloses the supporting mold 11, forming a closed main tube forming cavity. Molten material is then injected through the injection hole 125. After cooling, the main tube and its internal drug and gas channels are formed. The main tube mold 12 includes two mold blanks 121 mounted on two slides of the bidirectional linear slide rail 7. Semi-circular arc-shaped main tube forming grooves 123 are formed on the opposite surfaces of the two mold blanks 121. After mold closing, a complete circular main tube forming cavity is formed. End support rods 122 are fixedly connected to the ends of the inner walls of the mold blanks 121. When the mold is closed, the end support rod 122 is coaxially aligned with the main support rod 111 to ensure the overall coaxiality of the main tube forming. The inner wall of the mold blank 121 has a main tube forming groove 123. Two top support rods 124 are fixedly connected to the inner wall of the main tube forming groove 123. The two top support rods 124 correspond to the drug channel support rod 112 and the air channel support rod 113 respectively, and their diameters are the same as those of the drug channel support rod 112 and the air channel support rod 113. The bottom end also has a mating interface, which aligns with the drug channel support rod 112 during mold closing. The air channel support rod 113 is coaxially connected to ensure that the medicine channel and air channel can run through the entire main pipe without any breaks or misalignments. The mold blank 2 121 has an injection hole 2 125 inside. During injection, the molten material is evenly distributed along the main pipe forming groove 123 to ensure that the wall thickness of the main pipe is consistent. The top of the main support rod 111, the medicine channel support rod 112 and the mold blank 2 121 are all fixedly connected with a butt joint. The bottom of the end support rod 122 and the top support rod 124 are both provided with a butt joint corresponding to the butt joint. The joint and the butt joint are rigidly connected.

[0025] refer to Figures 12-15As shown, a bidirectional linear slide rail 4 (8) and a longitudinal linear slide rail 3 (9) are installed on the crossbeam of the gantry frame 1. The longitudinal linear slide rail 3 (9) is vertically installed on the top slide platform of the bidirectional linear slide rail 4 (8) and vertically installed on the top of the bidirectional linear slide rail 4 (8). A branch tube mold 13 is slidably installed on the bidirectional linear slide rail 4 (8). The branch tube mold 13 is used for injection molding of the drug tube and trachea that connect to the main tube. A connector mold 14 is slidably installed on the longitudinal linear slide rail 3 (9). The connector mold 14 is used for injection molding of the connector at the top of the drug tube and trachea, facilitating subsequent connection with anesthesia equipment. During the injection stage of the connector and branch tube, the horizontal... The linear slide rail 2 moves the support mold 11 directly below the branch pipe mold 13. The bidirectional linear slide rail 4 8 drives the two mold blanks 3 131 to move towards each other, so that the branch pipe mold 13 wraps around the outer wall of the support mold 11. Then, the longitudinal linear slide rail 3 9 drives the joint mold 14 to move downward, so that the joint support block 141 is inserted into the joint forming groove 134 of the mold blank 3 131, forming a closed branch pipe and joint forming cavity. Subsequently, molten material is injected through the injection hole 3 133 to form the medicine tube and gas tube, and molten material is injected through the injection hole 4 135 to form the joint. The branch pipe mold 13 includes two mold blanks mounted on the bidirectional linear slide rail 4 8. On the slide platform, two mold blanks 131 have two sets of semi-circular arc-shaped branch tube forming grooves 132 and one semi-circular arc-shaped connector forming groove 134 on their opposite surfaces. After mold closing, they form complete medicine tube, gas tube forming cavities, and connector forming cavities, respectively. Two branch tube forming grooves 132 are formed inside each mold blank 131. Injection holes 133 are also formed inside each mold blank 131, allowing for the injection of molten material. Injection holes 135 are also formed inside each mold blank 131, communicating with the connector forming groove 134. During injection, the molten material first fills the connector forming groove 134, and then... The molten material in the branch tube forming groove 132 is fused to ensure a firm connection between the joint and the branch tube. The joint mold 14 includes a joint support block 141 installed on the slide table of the longitudinal linear slide rail 39. The joint support block 141 has an end support rod 2 142 inside. The top of the mold blank 3 131 has a joint forming groove 134. The shape of the joint forming groove 134 is consistent with the outer wall of the joint. The bottom of the end support rod 2 142 has a mating interface corresponding to the mating joint. When mating, it is precisely matched with the mating joints of the drug channel support rod 112 and the air channel support rod 113 to avoid misalignment between the drug tube, air tube and drug channel, air channel.

[0026] Working principle: First, the bidirectional linear slide rail 4 drives the two main support rods 111 to merge, and the bidirectional linear slide rail 5 drives the two mold blanks 101 to close and wrap around the outer wall of the main support rods 111; at the same time, the baffle tube 117 extends from the top with the help of the spring force of the spring 116 and injects material into the airbag forming groove 103 of the mold blank 101 through the injection hole 102, forming an airbag between the forming groove and the airbag support block 114.

[0027] Next, the transverse linear slide rail 2 moves the longitudinal linear slide rail 1 3 and the support mold 11 to the two mold blanks 121, so that the main support rod 111 is located between the main tube forming groove 123; the bidirectional linear slide rail 3 7 drives the mold blank 121 to close, wrapping the main support rod 111; the longitudinal linear slide rail 2 6 adjusts the mold blank 121 to move down, so that the top of the main support rod 111 connects with the end support rod 1 122, and the top of the drug channel support rod 112 and the air channel support rod 113 connects with the top support rod 124; the longitudinal linear slide rail 1 3 moves the support mold 11 down, the airbag support block 114 shrinks relative to expose the airbag port, and the injection hole 2 125 injects material to form a main tube with drug channel and air channel, which merges with the airbag.

[0028] Then, the longitudinal linear slide rail 26 lifts the mold blank 2 121, causing the end support rod 1 122 to disengage from the joint. The bidirectional linear slide rail 3 7 drives the mold blank 2 121 to move to both sides, allowing the top support rod 124 to avoid the main pipe. Then, the mold blank 2 121 is lifted again to complete the demolding.

[0029] Subsequently, the transverse linear slide rail 2 moves the support mold 11 between the two mold blanks 131. The bidirectional linear slide rail 8 drives the mold blank 131 to close and wrap the main pipe. The longitudinal linear slide rail 9 drives the joint support block 141 to move down and get into the joint forming groove 134. The injection hole 133 injects material into the branch pipe forming groove 132 to form the medicine tube and the air tube. The injection hole 135 injects material to form the joint. Then, the joint support block 141 is raised and the mold blank 131 is opened to complete the demolding.

[0030] Finally, the transverse linear slide rail 2 with support mold 11 returns to the initial position, the bidirectional linear slide rail 2 5 opens the mold blank 101 to complete the demolding of the outer wall of the airbag, the fixture fixes the joint, the bidirectional linear slide rail 4 drives the support mold 11 to move to both sides, so that the drug channel support rod 112 and the air channel support rod 113 avoid the main tube, the longitudinal linear slide rail 3 with the main support rod 111 moves down to demold, the airbag support block 114 comes out from the gap between the airbag and the main tube, the electric heating ring melts the lower end of the airbag, the main support rod 111 expands outward to make the main tube and the airbag tightly fuse, and finally the airbag support block 114 is pulled out.
