Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment and supplies, in particular to an anti-falling anesthesia tube. Background Art

[0002] Epidural anesthesia is a commonly used clinical anesthesia technique. It involves puncturing and inserting a catheter in the appropriate spinous process space of the spine, and injecting local anesthetic nerve blocks into the epidural space through the catheter to achieve the effect of paralysis of the corresponding innervated area.

[0003] The Chinese patent application number 202320784742.2 discloses an anti-falling epidural anesthesia catheter connector, which is configured by passing the catheter through the catheter slot at the bottom of the connector tail body into the connector cap body, and injecting the drug into the inner groove through the syringe interface of the connector cap body before entering the catheter for use. On this basis, the connector cap body is threadedly rotated in the annular cap body slot of the connector tail body, and the inclined inner wall of the conical inner groove on the inner side of the connector tail body is used to squeeze the inner wall of the connector tail body when the connector cap body rotates and descends, and then the inner wall of the connector tail body is tightened together with the rubber ring, and the catheter passing through the center of the rubber ring is fixed. At this time, the hollow conical connector at the front end of the catheter can prevent the catheter from being pulled by external force and causing the catheter to fall out of the connector tail body, which can effectively avoid the risk of external infection caused by leakage or catheter falling off during drug injection;

[0004] However, when connecting the catheter to the syringe interface, the catheter is inserted into the connector tail body, and then the connector cap is rotated against the inner wall of the connector tail body to complete the connection of the catheter and the syringe interface. During this process, the friction force on the catheter is relatively large, and there is a possibility that the catheter will bend, which makes the connection between the catheter and the syringe interface more inconvenient. Utility Model Content

During this process, the friction force on the catheter insertion is relatively large, and there is a possibility that the catheter will be bent, which leads to the problem that the connection between the catheter and the syringe interface is relatively inconvenient.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-falling anesthesia tube, comprising a connecting block, a syringe connector is inserted into the inner side of the connecting block, a catheter is inserted into the inner surface of the connecting block located at the syringe connector, the catheter is inserted into the syringe connector, and four limiting mechanisms are symmetrically fixedly connected to the outer surface of the connecting block, two of which are in contact with the syringe connector, two of which are in contact with the catheter, and a fixing mechanism is bonded to the outer surface of the catheter.

[0009] Preferably, two sealing rings are fixedly connected to the outer surface of the syringe connector, and both of the sealing rings are in contact with the catheter.

[0010] Preferably, the four limiting mechanisms include four springs symmetrically fixedly connected to the outer surface of the connecting block, one end of the spring is fixedly connected to the limiting block, wherein two of the limiting blocks are in contact with the syringe connector, wherein two of the limiting blocks are in contact with the catheter, a side surface of the limiting block close to the spring is fixedly connected with a connecting rod, the spring is sleeved on the outer surface of the connecting rod, the four connecting rods are all slidably connected to the connecting block, one end of the connecting rod is fixedly connected to a connecting plate, a side surface of the connecting plate close to the connecting block is symmetrically fixedly connected with two limiting rods, and a plurality of limiting rods are all slidably connected to the connecting block.

[0011] Preferably, an oblique groove is provided on the outer surface of the limit block.

[0012] Preferably, the connecting block, the limiting block, the connecting rod, the connecting plate and the limiting rod are all made of plastic.

[0013] Preferably, the fixing mechanism comprises an adhesive tape bonded to the outer surface of the catheter, and a clip is bonded to the outer surface of the adhesive tape.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 3 , the utility model provides a technical solution:

[0025] An anti-falling anesthesia tube comprises a connecting block 1, a syringe connector 2 is inserted into the inner side of the connecting block 1, a catheter 3 is inserted into the inner surface of the connecting block 1 located on the syringe connector 2, the catheter 3 is inserted into the syringe connector 2, four limiting mechanisms 4 are symmetrically fixedly connected to the outer surface of the connecting block 1, two of which are in contact with the syringe connector 2, two of which are in contact with the catheter 3, and a fixing mechanism 5 is bonded to the outer surface of the catheter 3.

[0026] Specifically, Figure 1 and Figure 2As shown, two rubber pads 6 are symmetrically fixedly connected to the outer surface of the connecting block 1, one of the rubber pads 6 is in contact with the syringe connector 2, and the other of the rubber pads 6 is in contact with the catheter 3, thereby increasing the rotational friction between the syringe connector 2, the catheter 3 and the connecting block 1 and preventing the syringe connector 2 and the catheter 3 from rotating.

[0027] Specifically, Figure 1 and Figure 2 As shown, the outer surface of the connection block 1 is provided with anti-slip grooves to increase the contact friction with the fingers, thereby facilitating pinching the connection block 1 to connect the syringe connector 2 and the catheter 3 .

[0028] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, two sealing rings 7 are fixedly connected to the outer surface of the syringe connector 2 , and both sealing rings 7 are in contact with the catheter 3 , thereby improving the sealing performance between the syringe connector 2 and the catheter 3 .

[0029] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the four limiting mechanisms 4 include four springs 41 symmetrically fixedly connected to the outer surface of the connecting block 1, one end of the spring 41 is fixedly connected to the limiting block 42, wherein two limiting blocks 42 are in contact with the syringe connector 2, wherein two limiting blocks 42 are in contact with the catheter 3, a side surface of the limiting block 42 close to the spring 41 is fixedly connected with a connecting rod 43, the spring 41 is sleeved on the outer surface of the connecting rod 43, the four connecting rods 43 are all slidably connected to the connecting block 1, one end of the connecting rod 43 is fixedly connected to a connecting plate 44, a side surface of the connecting plate 44 close to the connecting block 1 is symmetrically fixedly connected with two limiting rods 45, and multiple limiting rods 45 are all slidably connected to the connecting block 1.

[0030] When in use, the syringe connector 2 is plugged into the connection block 1. When the syringe connector 2 contacts the limit block 42, the limit block 42 is forced to move toward the outside of the syringe connector 2. After the syringe connector 2 and the connection block 1 are plugged in, the limit block 42 is moved in the opposite direction to contact the syringe connector 2 through the elastic force of the spring 41, and the position of the syringe connector 2 is fixed. Then, the catheter 3 is plugged into the connection block 1. When the catheter 3 contacts the limit block 42, the limit block 42 is forced to move toward the outside of the catheter 3. After the catheter 3 and the connection block 1 are plugged in, the limit block 42 is moved in the opposite direction to contact the catheter 3 through the elastic force of the spring 41, and the position of the catheter 3 is fixed, thereby completing the connection between the syringe connector 2 and the catheter 3. At this time, the syringe connector 2 and the catheter 3 are in a plugged-in state;

[0031] When disassembling, the connecting plate 44 is moved, and the connecting rod 43 is driven to move by the movement of the connecting plate 44, and then the limiting block 42 is driven to move and separate from the syringe connector 2 and the catheter 3 by the movement of the connecting rod 43, and the fixed state of the syringe connector 2 and the catheter 3 is released, and the syringe connector 2 and the catheter 3 can be separated from the connecting block 1, and the disassembly of the syringe connector 2 and the catheter 3 is completed. In this process, the limiting block 42 is limited by the limiting rod 45, so that the movement of the limiting block 42 is stable;

[0032] The function of quickly connecting the syringe connector 2 and the catheter 3 is realized. Through the cooperation of the spring 41, the limit block 42, the connecting rod 43, the connecting plate 44 and the limit rod 45, the connection between the syringe connector 2 and the catheter 3 can be completed in a short time, which is more time-saving and labor-saving, thereby facilitating the connection between the syringe connector 2 and the catheter 3. After use, the syringe connector 2 and the catheter 3 can be disassembled relatively quickly, and the connecting block 1 and related structures can be reused to save resources.

[0033] Specifically, Figure 2 As shown, an oblique groove 8 is provided on the outer surface of the limit block 42 . When the syringe connector 2 and the catheter 3 are in contact with the limit block 42 , the limit block 42 can be moved by force, thereby facilitating the connection between the syringe connector 2 and the catheter 3 .

[0034] Specifically, Figure 1 and Figure 2 As shown, the materials of the connecting block 1, the limiting block 42, the connecting rod 43, the connecting plate 44 and the limiting rod 45 are all plastic materials, and the plastic has the characteristics of light weight and corrosion resistance.

[0035] Specifically, Figure 1 As shown, the fixing mechanism 5 includes an adhesive tape 51 bonded to the outer surface of the catheter 3 , and a clip 52 is bonded to the outer surface of the adhesive tape 51 .

[0036] When in use, the adhesive tape 51 is connected to the catheter 3, and the clip 52 is connected to the adhesive tape 51. The catheter 3 can be fixed to the bedside or the patient's collar by the clip 52, thereby completing the position fixation of the catheter 3;

[0037] The function of fixing the position of the catheter 3 is realized. Through the cooperation of the adhesive tape 51 and the clip 52, the catheter 3 can be fixed on the bedside or the patient's collar. When adjusting the fixed position of the catheter 3, the clamp 52 can be pinched to release the fixation of the catheter 3, and then the position of the catheter 3 can be fixed at a suitable position. The operation is simple, and the position fixation of the catheter 3 is convenient.

[0038] Working principle: When in use, the syringe connector 2 is plugged into the connection block 1. When the syringe connector 2 contacts the limit block 42, the limit block 42 is forced to move toward the outside of the syringe connector 2. After the syringe connector 2 and the connection block 1 are plugged in, the limit block 42 is moved in the opposite direction to contact the syringe connector 2 through the elastic force of the spring 41, and the position of the syringe connector 2 is fixed. Then, the catheter 3 is plugged into the connection block 1. When the catheter 3 contacts the limit block 42, the limit block 42 is forced to move toward the outside of the catheter 3. After the catheter 3 and the connection block 1 are plugged in, the limit block 42 is moved in the opposite direction to contact the catheter 3 through the elastic force of the spring 41, and the position of the catheter 3 is fixed, thereby completing the connection between the syringe connector 2 and the catheter 3. At this time, the syringe connector 2 and the catheter 3 are in a plugged-in state;

[0039] Then, the catheter 3 is fixed to the bedside or the patient's collar by means of a clip 52;

[0040] When disassembling, move the connecting plate 44, and the connecting rod 43 is driven to move by the movement of the connecting plate 44, and then the limit block 42 is driven to move and separate from the syringe connector 2 and the catheter 3 by the movement of the connecting rod 43, and the fixed state of the syringe connector 2 and the catheter 3 is released, so that the syringe connector 2 and the catheter 3 can be separated from the connecting block 1, and the disassembly of the syringe connector 2 and the catheter 3 is completed. In this process, the limit block 42 is limited by the limit rod 45, so that the movement of the limit block 42 is stable.
