Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a simple bladder clot removal device. Background Technology

[0002] Clinically, various factors can cause blood clots to form in the bladder, leading to difficulty urinating, urinary retention, abdominal distension and pain. In severe cases, bladder bleeding can result in hemorrhagic shock. Rapidly removing blood clots from the bladder and maintaining unobstructed urination are effective ways to relieve patient suffering and reduce bleeding. Currently, the most common methods for removing blood clots from the bladder are indwelling catheterization for bladder irrigation, or removal of the clots under electrocautery in the operating room. In severe cases, cystostomy or open bladder clot removal may be necessary. All non-minimally invasive methods for treating blood clots in the bladder require open surgery, which is more invasive to the patient and carries a higher risk of complications.

[0003] If small blood clots are not removed in time, they can form larger clots. Because the inner diameter of the catheter's discharge hole is very small, usually 2-3 mm, it is even more difficult to aspirate them. At the same time, when pushing or pulling the piston, liquid often sprays out from the connection point, and even bloody liquid may spray onto the eyes, posing a risk of hospital-acquired infection to medical staff.

[0004] In clinical practice, a piston-type "blood removal device" consisting of a metal catheter and a piston is often used. The negative pressure generated by pulling the piston is used to remove blood clots. It has the advantages of simple equipment, convenient operation, low investment, strong practicality, and easy promotion.

[0005] Because blood clots continuously dissolve and detach, small clots frequently clog the catheter, requiring medical staff to repeatedly aspirate, which is labor-intensive. During use, the inventors discovered that existing blood-drawing devices have weak suction, and with repeated aspiration, the negative pressure effect significantly decreases. Summary of the Invention

[0006] The purpose of this invention is to overcome the above-mentioned problems in the prior art and provide a bladder blood clot remover with a simple structure, which has the advantages of simple and reasonable structure, convenient use, clean removal of blood clots, and high efficiency.

[0007] To solve the above-mentioned technical problems, the present invention provides a bladder blood clot remover with a simple structure, comprising: a hollow sleeve and an inner core, wherein the hollow sleeve has a water inlet at the tail end, the head of the hollow sleeve is upturned, and an elongated hole is provided on the back side of the upturned part of the hollow sleeve, the length direction of the elongated hole being consistent with the length direction of the hollow sleeve; the water inlet is provided with a closing device.

[0008] The inner core is inserted into the hollow sleeve from the tail end. The diameter of the head of the inner core is larger than the diameter of the middle part of the inner core. The head of the inner core is provided with a groove, and an elastic ring is sleeved in the groove.

[0009] When the inner core is inserted into the hollow sleeve from the tail end, a piston effect is formed between the elastic ring and the middle of the hollow sleeve.

[0010] Preferably, the hollow sleeve has multiple side holes on both sides of its head, arranged in parallel along the length of the hollow sleeve. This structure increases the flow area of ​​the blood clot entering the hollow sleeve. Furthermore, since the side holes are arranged in parallel along the length of the hollow sleeve, each side hole corresponds to the sidewall on the other side of the hollow sleeve. When the blood clot is aspirated, the sidewall blocks and forces the blood clot to flow along the length of the hollow sleeve.

[0011] Preferably, the elongated hole is an elliptical hole.

[0012] Preferably, the hollow sleeve and / or inner core are made of metal, which not only allows for repeated use but also provides better toughness and reliability.

[0013] Preferably, the top end of the hollow sleeve is also provided with a hole, which increases the rinsing angle during rinsing.

[0014] Preferably, the hollow sleeve is provided with a handle at its tail end.

[0015] Preferably, the closing device is a one-way valve. During cleaning, the inner core is pulled back to the tail of the hollow sleeve, and cleaning fluid is injected through the inlet. After cleaning, the waste liquid is discharged from the hollow sleeve. Since the closing device is a one-way valve, the waste liquid and blood clots cannot flow out of the inlet in reverse during cleaning and blood clot removal, and will not contaminate the clean cleaning fluid.

[0016] Preferably, there are multiple grooves arranged along the length of the inner core, and each groove is provided with an elastic ring.

[0017] Preferably, the groove is provided with a slot along the length of the inner core near the tail end of the inner core, and the elastic ring is provided with a protrusion. When the elastic ring is sleeved in the groove, the protrusion is engaged in the slot. During suction, the inner core and the hollow sleeve will rotate. The cooperation of the slot and the protrusion restricts the rotation of the elastic ring in the groove and maintains the suction force.

[0018] Preferably, the diameter of the head of the hollow sleeve is smaller than the diameter of the middle part of the hollow sleeve. When the inner core is inserted into the hollow sleeve from the tail end, the head of the hollow sleeve can play a positioning role for the inner core. At the same time, due to the reduced diameter of the head of the hollow sleeve, the pressure of the cleaning fluid sprayed out from the hole at the head of the hollow sleeve during rinsing is increased, thereby improving the cleaning effect.

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] Because a long hole is located on the dorsal side of the upward-curving portion of the hollow cannula, saline solution can enter the catheter and flow into the bladder through the inlet. When the inner core is pulled outward, negative pressure is created at the long hole at the head of the hollow cannula, which can aspirate large blood clots, saline solution, and urine from the bladder. The hollow cannula can be rotated, tilting the long hole to the left or right, allowing blood clots from the bladder sidewall to be drawn into the hollow cannula and removed. The head of the inner core features mating grooves and an elastic ring, providing excellent suction force that does not decrease with repeated suction. The elastic ring can also be replaced to control the suction force.

[0021] Extensive practical experience has shown that this bladder clearer can effectively remove blood clots from the bladder. It can be operated under local anesthesia, reducing the occurrence of complications such as epidural or general anesthesia, and minimizing medical disputes. This invention is simple in structure, easy to manufacture, and convenient to use, and is suitable for bladder packing caused by blood clots from various reasons. Attached Figure Description

[0033] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0034] The term "comprising" and its variations as used herein signify open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment".

Other explicit and implicit definitions may also be included below.

[0035] To at least partially address one or more of the above-mentioned problems and other potential problems, embodiments of this disclosure propose several structurally simple bladder clot removers.

[0036] Example 1

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 The bladder clot remover shown includes: a hollow sleeve 1 and an inner core 2. The hollow sleeve has an inlet 4 at its tail 3 and an upward-curving head 21. An elongated hole 6 is provided on the back side of the curved part of the hollow sleeve. The length direction of the elongated hole 6 is consistent with the length direction of the hollow sleeve 1. The inlet 4 is provided with a closing device (not shown in the figure).

[0038] The inner core 2 is inserted into the hollow sleeve from the tail 3 of the hollow sleeve. The diameter of the head 21 of the inner core is larger than the diameter of the middle part of the inner core. The head 21 of the inner core is provided with a groove 8, and the elastic ring 7 is sleeved in the groove 8.

[0039] When the inner core 2 is inserted into the hollow sleeve 1 from the tail 3 of the hollow sleeve, a piston effect is formed between the elastic ring 7 and the middle of the hollow sleeve.

[0040] In this example, the diameter of the middle part of the hollow sleeve is 8.3mm, the elongated hole 6 is an elliptical hole with a major axis of 15mm and a minor axis of 8.3mm, and is located on the back side of the head of the hollow sleeve, with a straight-line distance of 30mm from the top of the head 5 of the hollow sleeve. The hollow sleeve and / or the inner core are made of metal, which not only allows for repeated use but also has better toughness and reliability.

[0041] Based on the aforementioned basic structure, to increase the flow area of ​​the blood clot entering the hollow sleeve, in this embodiment, multiple side holes 62 are provided on both sides of the head 21 of the hollow sleeve, arranged side by side along the length of the hollow sleeve. Since the side holes are arranged side by side along the length of the hollow sleeve, each side hole corresponds to the sidewall of the other side of the hollow sleeve. When the blood clot is aspirated, the sidewall blocks and forces the blood clot to flow along the length of the hollow sleeve. When there are two side holes 62, they can be staggered one after the other.

[0042] Furthermore, in order to increase the rinsing angle during rinsing, a hole is also provided at the top of the head of the hollow sleeve.

[0043] Furthermore, for ease of use, the tail end 3 of the hollow sleeve is provided with a handle 31.

[0044] In this embodiment, no specific closing device is shown. The closing device may be a one-way valve or switch installed at the inlet. During cleaning, the inner core is pulled back to the tail of the hollow sleeve, and the cleaning fluid is injected through the inlet. After cleaning, the waste liquid is discharged from the hollow sleeve. Since the closing device is a one-way valve or switch, the waste liquid and blood clots cannot flow out of the inlet in reverse during cleaning and blood clot removal, and will not contaminate the clean cleaning fluid.

[0045] Furthermore, in order to improve the suction force and the reliability of the device, there are two grooves 8 arranged along the length of the inner core 2, and each groove 8 is provided with an elastic ring 7.

[0046] Example 2

[0047] like Figure 5 The image shown is another structural example of inner core 2; other structures are referenced. Figure 1 , Figure 2 , Figure 3 Compared to Embodiment 1, the improvements lie in the groove 8 and the elastic ring 7. The groove 8 has a slot 81 along the length of the inner core, near the tail 22 of the inner core. The elastic ring 7 has a protrusion 71. When the elastic ring 7 is fitted into the groove 8, the protrusion 71 engages with the slot 81. During suction, the inner core 2 and the hollow sleeve 1 will rotate. The engagement of the slot 81 and the protrusion 71 restricts the rotation of the elastic ring 7 in the groove 8, thus maintaining the suction force.

[0048] Example 3

[0049] like Figure 6 , Figure 7 The image shows another structural example of the hollow sleeve 1; other structures are shown in the figure. Figure 1 , Figure 2 , Figure 3 , Figure 4 or Figure 5 In this embodiment, the improvement lies in the head 5 of the hollow sleeve. The diameter of the head 5 of the hollow sleeve is smaller than the diameter of the middle part of the hollow sleeve. When the inner core 2 is inserted into the hollow sleeve from the tail 3, the head 5 of the hollow sleeve can play a positioning role for the inner core. At the same time, due to the reduced diameter of the head 5 of the hollow sleeve, the pressure of the cleaning fluid sprayed out from the hole at the head of the hollow sleeve during rinsing is increased, thus improving the cleaning effect.

[0050] Furthermore, to facilitate the removal of larger blood clots, such as Figure 8 As shown, it can be improved by making the diameter of the head 5 of a portion of the hollow sleeve smaller than the diameter of the middle part of the hollow sleeve. For example, the diameter of the head 5 of the hollow sleeve with the first side hole is kept consistent with the diameter of the middle part of the hollow sleeve, and only the diameter of the end near the head 5 of the hollow sleeve is reduced.

[0051] When using any of the above-described structures or combinations of structures for bladder clot removal, first insert the tip of the hollow cannula 1 into the bladder to aspirate the urine, then continue to aspirate as many blood clots as possible. Once the bladder pressure decreases, the patient's abdominal distension and pain will immediately subside. Then, 20ml to 50ml of normal saline is pumped into the bladder under high pressure. The saline sprays out from the flushing port of the metal catheter, breaking up the blood clots in the bladder. Pulling the inner core 2 draws the blood clots into the metal catheter (hollow cannula 1). Repeated flushing can remove as many blood clots as possible from the bladder. Simultaneously, an assistant can gently massage the patient's lower abdomen in the bladder area to move any blood clots attached to the bladder wall to the bottom of the bladder, where they can continue to be aspirated through the catheter. A simple way to determine if the bladder clots are basically cleared is to inject 50ml of normal saline; approximately 50ml of saline should be easily withdrawn. Through practice, this device has shown to significantly improve the clearance rate and result in high patient satisfaction.

[0052] Injecting 50ml of normal saline is achieved by connecting the syringe tip to the inlet 4 of the hollow cannula 1 via a connecting tubing. The syringe tip is inserted into the connecting tubing, which is then fitted into the inlet 4. Due to the elasticity of the connecting tubing, the connection between the tubing, the syringe tip, and the hollow cannula is tight, preventing water leakage during blood clot aspiration. The connecting tubing is 50mm long and 8.3mm in diameter. The syringe tip is conical, 30mm long, and made of a hard plastic material commonly used in medical equipment. The syringe barrel is 70mm long and 30mm in inner diameter, made of a translucent cylindrical hard plastic material commonly used in medical equipment. The syringe barrel has volume markings on its outer wall, from the tip to the bottom, up to 50ml. The hollow cannula has outwardly protruding handles 31 on both sides of its rear section. When the hollow cannula is inserted into the bladder, it can be adjusted by rotating the handles 31.

[0053] The beneficial effects of this invention are as follows: When treating blood clots formed by blood accumulation in the bladder, the negative pressure generated by extracting the inner core draws the blood clots out through the holes in the hollow tube, without damaging the bladder mucosa. The inlet 4 is equipped with a one-way valve. This structure not only facilitates blood clot removal and cleaning but also has an injection function. During cleaning and blood clot removal, cleaning waste liquid and blood clots will not pass through the inlet, thus preventing contamination of the clean cleaning solution. This invention has a simple and reasonable structure, low cost, and facilitates blood clot removal and cleaning, making it suitable for bladder blood clot removal in many grassroots hospitals with limited medical resources.
