Background
The infusion is a method of injecting liquid medicine into human body's vein by using the principle of pressure difference (gravity) produced by liquid drop height, and is a common method for clinical rescue and treatment of patients.
The work of intravenous drip infusion has been manually operated, monitored and cared by medical personnel for many years. Due to uncertainty of environment factors of manual operation behaviors, such as: dust, fiber bacteria, viruses or other particles in the air, and uncertain environmental influence factors of medical personnel can cause imperceptible pollution to liquid medicine when the medical personnel carry out transfusion and convert the transfusion bottle, thereby bringing negative effects to clinical safe medication.
In addition, the conventional artificial intravenous drip infusion often has the phenomenon of over-input of liquid medicine due to untimely manual monitoring, so that negative pressure difference is generated between the inside of the infusion tube and blood, the blood flows back into the infusion tube, and serious consequences are caused. The biggest harm is that in order to reduce workload, medical staff can re-input the blood in a coagulated state in the infusion tube into the blood of a patient, which may bury the pen-hold for the formation of thrombus and may increase the incidence of cerebral thrombosis and cerebral infarction.
Bubbles are easily generated in the process of infusion, and if the bubbles enter a human body without being treated in time, hidden troubles are brought to the health of the human body. The common medical staff measures to process the bubbles include that the liquid medicine is squeezed into the drip cup again, or the needle head of the infusion tube is pulled out to remove the discharged bubbles and then is inserted into the drip cup again, so that the processing process is complex, the infusion of the patient is influenced, and the labor intensity of the medical staff is increased.
When the artificial intravenous drip is used for transfusion, the needle inserted by medical staff cannot be completely inserted into a vein, so that the liquid medicine is injected into the muscle of a patient, the medical staff cannot find the needle in time, and the phenomenon of edema of the peripheral skin and the muscle of the needle inserted by a transfusion person when the needle is found not can be caused, so that the liquid medicine loss can be caused, the treatment effect can be influenced, and the pain of frosting on snow can be caused for the patient.
In the infusion process, no equipment for well controlling the infusion temperature exists in the existing market, and only one simple heating rod is used for heating the temperature of the infusion liquid in the existing market; and the heater is disposable, so that the heater can not be repeatedly used and is much wasted.
An effective solution to the problems in the related art has not been proposed yet.

Referring to fig. 3, the limiting mechanism 103 comprises a stopper 103c disposed at the top end of the infusion bottle fixing device 100, a first limiting adjustment part 103a and a second limiting adjustment part 103b disposed on the transmission pushing block 102a-4, a third transmission part 102d and a fourth transmission part 102e connected to the first limiting adjustment part 103a and the second limiting adjustment part 103b, respectively, and a first guide part 104a and a second guide part 104b disposed on the inner side surfaces of the third transmission part 102d and the fourth transmission part 102e, respectively. In this embodiment, the blocking body 103c may have a specific structure that the blocking body 103c is inverted in a "concave" shape in a plan view, and both end arms forming the inverted "concave" shape are connected to the third transmission member 102d and the fourth transmission member 102e, respectively. So configured, a "guide rail" may be provided for the third transmission member 102d and the fourth transmission member 102e during ascent or descent. One end of the first guide part 104a penetrates through the first boss 101a-1 from the third transmission part 102d through the through hole of the first boss 101a-1, is movably connected with the first boss 101a-1 until the other end forms a blocking block, and an elastic recovery part is arranged between the blocking block and the first boss 101 a-1; one end of the second guiding component 104b penetrates through the second boss 101b-1 from the fourth transmission component 102e through the through hole of the second boss 101b-1, and is movably connected with the second boss 101b-1 until the other end forms a blocking block, and an elastic recovery component is arranged between the blocking block and the second boss 101 b-1.
The power unit 102a supplies driving force to the driving mechanism 102 for fixing and releasing the iv bag. The drive mechanism 102 includes a power member 102a and first and second transmission members 102b and 102c connected to the power member 102 a. In this embodiment, referring to fig. 3, the power unit 102a includes a power source 102a-1, a fixing plate 102a-2 disposed at an upper end of the power source 102a-1, a first transmission rail 102a-3 and a second transmission rail 102a-5 disposed at both ends of the fixing plate 102a-2 and abutting against a lower end surface a of the stopper 103c, and a transmission push block 102a-4 directly connected to a power input shaft of the power source 102 a-1. Here, the power input shaft of the power source 102a-1 passes through the fixing plate 102a-2 at the upper end thereof, is movably connected with the fixing plate 102a-2, and is fixedly connected with the transmission push block 102 a-4. The transmission push block 102a-4 is also movably connected with the first transmission track 102a-3 and the second transmission track 102 a-5. The power source 102a-1 may be selected here as a hydraulic rod, but is not particularly limited as long as it is formed as a mechanism capable of reciprocating in the vertical direction.
The third transmission component 102d and the fourth transmission component 102e are movably connected with the first transmission track 102a-3 and the second transmission track 102a-5 through hollow components respectively, and an elastic component is arranged between the hollow components and the transmission push block 102 a-4. The third transmission member 102d and the fourth transmission member 102e may be selected to have a block shape, i.e., a rectangular parallelepiped structure, and the "hollow member" connected thereto has a hollow structure, and can move on the first transmission rail 102a-3 and the second transmission rail 102a-5 depending on the shape of the first transmission rail 102a-3 and the second transmission rail 102 a-5. In this embodiment, first drive face D1 is configured to slope downwardly below the "axis of symmetry". Correspondingly, the second transmission component 102c is provided with a second transmission surface D2 which is matched with the second guide surface E2, and the second transmission surface D2 is also arranged in a structure which inclines towards the lower part of the symmetrical axis. Taking the example that the first guiding surface E1 is relatively displaced on the first driving surface D1, the first guiding surface E1 has a moving distance on the first guiding component 104a from the farthest end of the first driving surface D1 of the inclined structure to the limit position where the first guiding component 104a is abutted, so that the first boss 101a-1 can be close to the third driving component 102D and far from the third driving component 102D. Here, the "farthest end of the first transmission surface D1" means the highest point of the first transmission surface D1, which is disposed obliquely, from the horizontal plane where the transmission pushing block 102a-4 is located. Similarly, the second guiding surface E2 has a moving distance on the second guiding element 104b from the farthest end of the second transmission surface D2 to the limit position where it collides with the second guiding element 104b, so as to allow the second protrusion 101b-1 to approach the fourth transmission element 102E and move away from the fourth transmission element 102E.
Fig. 4 to 7 and fig. 1 to 3 show the whole operation process of the iv fixing apparatus 100 as shown in fig. 4 to 7. In the utility model discloses a, when power part 102a provides power and passes through the power input shaft of power source 102a-1 and transmit to transmission ejector pad 102a-4, each part moves on first transmission track 102a-3 and second transmission track 102a-5 under the promotion of total thrust F (F is far greater than 2F1), under the elastic component effect between the lower terminal surface of hollow component and transmission ejector pad 102a-4, keeps its distance H2 between each other invariable, and H2 is more than or equal to W sin alpha this moment. The distance 2W between the first engaging member 101a and the second engaging member 101B in the horizontal direction is constant under the action of the elastic restoring members provided on and above the first guide member 104a and the second guide member 104B of the first guide member 104a, and under the action of the horizontal position limitation of the first abutting surface B1 and the first position-retaining surface C1, the second abutting surface B2, and the second position-retaining surface C2. The main function of the first limit adjusting part 103a and the second limit adjusting part 103b in this movement is to maintain the elastic tension between the hollow part and the elastic part between the transmission pushing block 102a-4, thereby ensuring the stability of H2 and simultaneously playing the balance role for the moving part.

The exhaust mechanism 400 includes a driving rod member 401 having one end connected to the power member 102a and the other end extending downward to form a driving end 401 a; a drip cup fixing member 402 having a drip cup bayonet 402a for fastening and fixing the drip cup and a through hole 402b communicating with the drip cup bayonet 402 a; and one end of the exhaust pushing component 403 can penetrate through the through hole 402b to push the drip cup clamped in the drip cup clamping opening 402a, the other end of the exhaust pushing component 403 is provided with an exhaust pushing component 403 (see fig. 13) with a transmission end 403a matched with the pushing end 401a, and the exhaust pushing component 403 finally converts the force transmitted by the transmission guide rod component 401 into the force pushing the drip cup, so that the redundant air in the drip cup or the infusion tube is exhausted.
In one embodiment, the pusher end 401a includes a first pusher face 401a-1 and a second pusher face 401 a-2. For better illustration of the venting movement of the venting mechanism 400 for the infusion line or drip chamber, the first push surface 401a-1 is set: which extends to one side and most distally abuts the face formed by the end point of the pushing end 401 a. Thus, the second pushing surface 401a-2 is a surface extending to the same side as the first pushing surface 401a-1 and abutting against the end point of the pushing end 401a at the farthest. That is, the final intersection of the first pusher face 401a-1 and the second pusher face 401a-2 forms a pusher end 401a, which allows the drive end 403a to move along the first pusher face 401a-1 past the end of the pusher end 401a and then continue along the second pusher face 401 a-2. Here, the lowermost end of the drive link member 401 will extend beyond the entirety of the pushing end 401a, acting as a stop to ensure that the drive end 403a will not fall off the second pushing surface 401 a-2.
Preferably, the exhaust pushing member 403 includes an exhaust pushing rod 403b capable of passing through the through hole 402b, where, as shown in fig. 14 and 15, the through hole 402b includes a large hole section 402b-1 and a small hole section 402b-2, and the diameter of the large hole section 402b-1 is larger than that of the small hole section 402b-2, so that the connection point thereof forms an abutting end of the exhaust pushing rod 403b, or more precisely, an abutting end of the top rod 403b-1 of the exhaust pushing rod 403 b. The exhaust push rod 403b is divided into a top rod 403b-1 capable of passing through the small hole section 402b-2 and a concave surface 403b-2 matched with the large hole section 402b-1, and the diameter of the concave surface 403b-2 is larger than that of the top rod 403b-1, so that only the top rod 403b-1 in the exhaust push rod 403b is allowed to pass through the small hole section 402b-2, and the concave surface 403b-2 can only move in the hollow space in the large hole section 402 b-1.
Exhaust pushing member 403 also includes an exhaust return rod 403c connected to exhaust pushrod 403b, and an exhaust retainer 403d connected to exhaust return rod 403 c. Here, exhaust return lever 403c includes a drive rod 403c-1 that mates with concave surface 403b-2, a locating surface 403c-2 having a diameter greater than the diameter of drive rod 403c-1, and a drive end 403a that is provided with a first return surface 403a-1 and a second return surface 403 a-2. Here, the first restoring surface 403a-1 and the second restoring surface 403a-2 are configured similarly to the first pushing surface 401a-1 and the second pushing surface 401a-2, that is, the first restoring surface 403a-1 is a "surface": which is the surface extending to one side and abutting against the end point of the driving end 403a farthest. The second pushing surface 401a-2 extends toward the same side as the first restoring surface 403a-1 and is the surface formed by the end point of the driving end 403 a. The first return surface 403a-1 and the second return surface 403a-2 eventually intersect to form a drive end 403 a. An understanding of the unique design of exhaust return rod 403c requires reference to the structural arrangement of exhaust locator 403 d.

Thus, when the power component 102a moves upward, the linkage driving guide rod component 401 moves upward together, and at this time, the end point of the pushing end 401a and the end point of the driving end 403a are at the farthest distance, the first pushing surface 401a-1 moves along the second restoring surface 403a-2, and as the end point of the pushing end 401a and the end point of the driving end 403a approach, the first pushing surface 401a-1 of the driving guide rod component 401 gradually pushes the exhaust restoring rod 403c to the horizontal direction, compresses the elastic restoring component on the driving rod 403c-1, and further pushes the exhaust pushing rod 403b to pass through the through hole 402b to extrude the drip chamber to exhaust air. Then, beyond the end point of the driving end 403a, the second pushing surface 401a-2 comes into contact with the first restoring surface 403a-1, and as the end point of the pushing end 401a and the end point of the driving end 403a are far away, the ejector 403b-1 of the exhaust push rod 403b is pulled out from the small hole section 402b-2 and "pushes" back to the moving rod 403c-1, at this time, the elastic restoring component in the hollow space of the exhaust retainer 403d "abuts against the positioning surface 403c-2, so as to force the exhaust restoring rod 403c to restore to the end point of the pushing end 401a and the end point of the driving end 403a at the farthest distance, and the drip cup which was previously squeezed and deformed recovers due to the withdrawal of the squeezing force. In this embodiment, a drive guide positioning part (see fig. 14, not shown) is preferably disposed on the drive guide part 401, and is connected to a support rod (see fig. 12) supporting the whole infusion bottle fixing puncture bottle-changing air-discharging device, so as to ensure the movement track of the drive guide part 401 in the vertical direction.
