Abstract

The utility model relates to the technical field of medical equipment, and discloses an intraoperative catheter for preventing blockage, which comprises a catheter body and a nozzle, wherein the nozzle is integrally formed at one end of the catheter body, the nozzle is in an annular wavy structure, and a plurality of blood sampling holes are uniformly formed in the outer side wall of the nozzle; set up annular wavy through the mouth of pipe with the heparin tube, when making the heparin tube stretch into the internal blood sampling that carries on of patient, internal tissue or organ are difficult to become stifled tight with the mouth of pipe, and a plurality of blood sampling holes have evenly been seted up to orificial lateral wall, the work of taking a blood sample that can be better, in addition, annular wavy mouth of pipe cooperates a plurality of blood sampling holes of its lateral wall, can keep the inside and outside pressure of heparin tube unanimous, can not cause the condition that the heparin tube is difficult to extract because of pressure, make things convenient for medical personnel to use more.

Description

Catheter for preventing blockage in operation

Technical Field

The utility model relates to the technical field of medical equipment, in particular to an intraoperative catheter capable of preventing blockage.

Background

The medical apparatus refers to instruments, equipment, appliances, in-vitro diagnostic reagents and calibrators, materials and other similar or related articles which are directly or indirectly used for the human body, and comprises required computer software for diagnosing, preventing, monitoring, treating or relieving diseases; diagnosis, monitoring, treatment, mitigation, or functional compensation of injury; examination, replacement, regulation or support of a physiological structure or physiological process; support or maintenance of life; controlling pregnancy; through examining the sample that comes from the human body, for medical treatment or diagnosis purpose provide information, diagnose for better patient, medical personnel often can stretch into patient's internal work of taking a blood sample through the heparin tube, traditional heparin tube is when deepening patient's internal blood sampling, the mouth of pipe is blocked by tissue or organ around the blood vessel very easily and can not take a blood sample, and because the reason of pressure, the pipe is difficult to be taken off, extract by force and cause the injury to patient's tissue or organ easily again.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

The utility model provides a prevent intraoperative catheter of jam to prior art not enough, has solved the problem that exists among the above-mentioned background art.

(II) technical scheme

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a prevent intraoperative catheter of jam, includes body and mouth of pipe, the one end integrated into one piece of body has the mouth of pipe, the mouth of pipe is annular wavy structure, just a plurality of blood sampling holes have evenly been seted up to orificial lateral wall.

Preferably, the plurality of blood sampling holes are communicated with the inside of the tube mouth.

(III) advantageous effects

The utility model provides a prevent intraoperative catheter of jam possesses following beneficial effect:

the utility model discloses a set up the mouth of pipe of heparin tube annular wavy, when making the heparin tube stretch into the internal blood sampling that carries out of patient, internal tissue or organ are difficult to become stifled strictly with the mouth of pipe, and a plurality of blood sampling holes have evenly been seted up to orificial lateral wall, the work of taking a blood sample that can be better, in addition, annular wavy mouth of pipe cooperates a plurality of blood sampling holes of its outer lateral wall, can keep the inside and outside pressure of heparin tube unanimous, can not cause the condition that the heparin tube is difficult to extract because of pressure, make things convenient for medical personnel to use more.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. a pipe body; 2. a pipe orifice; 3. a blood sampling hole.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the utility model provides a technical solution: the utility model provides a prevent art in pipe of jam, including body 1 and mouth of pipe 2, the one end integrated into one piece of body 1 has mouth of pipe 2, mouth of pipe 2 is annular wavy structure, and a plurality of blood sampling holes 3 have evenly been seted up to the lateral wall of mouth of pipe 2, annular wavy mouth of pipe 2, can make the heparin tube go deep into when mixing internal blood sampling, mouth of pipe 2 is difficult to by the internal tissue or the stifled rigor reality of organ, and a plurality of blood sampling holes 3, can be better carry out the blood sampling operation to the patient, and a plurality of blood sampling holes 3 on wavy mouth of pipe 2 cooperation its outer wall, can keep the blood sampling intraductal outer pressure unanimous, the convenience is after the blood sampling finishes, extract the heparin tube from patient's is internal.

Further, a plurality of blood sampling holes 3 all are linked together with the inside of mouth of pipe 2, and the in-process of being convenient for at the blood sampling, the internal blood of patient can enter into mouth of pipe 2 through a plurality of blood sampling holes 3, enters into in the body 1 via mouth of pipe 2 again.

To sum up, the utility model discloses a work flow: when using, with the heparin tube deepening mix internal, because mouth of pipe 2 is annular wavy structure, consequently, pipeline 2 can not be mixed internal tissue or the stifled rigor of organ tightly, and cooperate a plurality of blood sampling hole 3 on its outer wall, can be better with the internal blood of patient take out, wavy mouth of pipe 2 cooperates a plurality of blood sampling hole 3 on its outer wall in addition, can keep the blood sampling intraductal outer pressure unanimous all the time, avoid finishing taking a blood sample, under the effect of pressure, lead to whole heparin tube to be difficult to the condition of following the internal extraction of patient.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
