A device for shunting and merging of medical catheters

Abstract

The invention relates to a distribution and confluence device of a medical catheter. According to the solving scheme, the device comprises a left tube sleeve and a right tube sleeve, wherein a longitudinal semi-round left through groove is formed in the right end of the left tube sleeve, a longitudinal semi-round right through groove is formed in the left end of the right tube sleeve, the axis of the left through groove and the axis of the right through groove coincide, and the two through grooves are equal in radius. A sliding block capable of sliding in a left-right mode to penetrate through the right tube sleeve is installed on the right tube sleeve and is provided with two blades arranged at the left end of the sliding block, and the two blades are aligned to the front end face and the rear end face of the sliding block respectively. A longitudinal round through hole is formed in the left portion of the sliding block, the round through hole and the axis of the right through groove are located in the same horizontal plane, a distribution hole communicated with the round through hole is formed in the right end face of the sliding block, and a sinking groove matched with the sliding block is formed in the right end face of the left tube sleeve. The distribution and confluence device is ingenious in structure and can be directly operated on an existing catheter when distribution, confluence or remediation is needed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a device for shunting and merging medical catheters. Background technique [0002] As a conventional medical device, medical catheter is the preferred medium for gas or liquid transmission between the human body and the outside world. There are many types of medical catheters, which can meet the different needs of conventional operations, such as single-lumen tubes and multi-lumen tubes. Tubes, single-channel transmission catheters, multi-channel transmission catheters that can merge or diverge, etc. In actual operation, the required medical catheters can be selected according to the usage conditions. [0003] However, in the face of some complex situations, such as major surgery, the condition may exceed the prediction or the patient's signs are unstable, so that the used catheters cannot meet the actual needs, and it is necessary to divert gas or liquid or Drainage is used to co...

Problems solved by technology

[0003] However, in the face of some complex situations, such as major surgery, the condition may exceed the prediction or the patient's signs are unstable, so that the used catheters cannot meet the actual needs, and it is necessary to divert gas or liquid or Drainage is used to complete further treatment. At this time, we can only choose to add additional gas or liquid transmission equipment or replace the catheter with a multi-channel transmission catheter; adding transmission equipment will obviously increase the economic burden of patients, and to a certain extent will cause medical resources. Resources can not be fully utilized, resulting in waste of resources; although replacement of the catheter is simple and economical, the original catheter needs to be pulled out from the patient's body and reinserted after replacement, which will bring a certain amount of physical pain and mental burden to the patient; moreover, For some patients who need to temporarily rely on transmission therapy such as oxygen or blood to maintain vital signs, once the catheter is pulled out of the body for replacement, even if the replacement speed is fast, it is also easy to cause medical safety accidents

[0004] Secondly, in some emergency rescue, outdoor rescue and other situations, in addition to the above-mentioned situations, there will also be insufficient backup resources. Inability to perform operation due to insufficient delivery equipment or insufficient divertable catheters

[0005] Thirdly, during the surgical operation or rescue process, if the catheter is damaged due to the patient’s emotional agitation or other accidental factors, and air or fluid leakage occurs, a new catheter needs to be replaced and reinserted into the patient’s body, but at this time It may be difficult to replace the catheter due to the patient's reluctance to actively cooperate or other factors

[0006] In addition, for some special patients, it is often necessary to temporarily add other drugs or liquids during the infusion of drugs or liquids for further treatment. Another intubation operation on another body part of the patient is likely to bring discomfort and mental stress to the patient, and various drugs cannot be fully mixed and absorbed in the body, which affects the therapeutic effect
